Mushroom galette

Looing for a stunning fall or winter vegetarian dinner idea? Try a savory Mushroom Galette! This free-form French tart isn’t just for dessert. Make it with a savory filling and it’s a fun vegetarian main dish, like a quiche. This one stars meaty mushrooms, layered over a fluffy smear of ricotta and Parmesan cheese and scented with garlic and fresh thyme. It’s all packed into a flaky, buttery crust and baked to perfection. The smell alone had us salivating before the first bite. Ready to bake?

Ingredients for this mushroom galette

galette is a rustic French tart: a round pie made without a pie dish using a folded pastry crust. That’s right: no pie plates or precise rolling and cutting! Simply roll out the dough, add filling and fold over the crust. Galettes are most often served as desserts, like a peach galette or blueberry galette. But they work as savory pies too, like a tomato galette or mushroom galette. Here’s what you’ll need for this mushroom galette recipe:

  • Mushrooms: a mix of cremini (baby bella) and shiitakes makes for a nuanced, complex flavor
  • Olive oil
  • Soy sauce
  • Garlic powder, onion powder, smoked paprika, dried thyme
  • Ricotta cheese
  • Parmesan cheese
  • Garlic
  • Fresh thyme
  • Flour
  • Butter
  • Salt
  • Baking powder
  • Egg

Tips for working with galette dough

The main part of this mushroom galette that takes a bit of technique? The pastry dough! Now, this galette dough is easy to work with, but there are a few things to keep in mind when making the pastry. Here are a few tips:

  • Weigh the flour in grams (or spoon and level it). Weighing your flour on a food scale in grams provides the most accurate measurement (and it’s less messy, we find!) Or you can spoon the flour into the measuring cup, then level it with the back of the spoon. This is more accurate than scooping flour right out of the container, which can result in more flour per cup.
  • Add just enough water for the dough to come together. It should take around 5 to 6 tablespoons, but maybe slightly more depending on the exact flour amount.
  • Chill 1 hour. Chilling is important, so that the butter can solidify. Otherwise, the crust can melt in the oven.
  • Roll into a 12-inch circle, then add the filling. Flour your work surface first. Pick up the dough and add more flour to the surface as necessary if it’s sticking. Then add the ricotta filling and mushrooms.
  • Gently fold it up to create a 2-inch crust. Overlap the folds to make a circle around the filling: see the photos.

For the egg wash

Before baking this mushroom galette, it’s important to brush the crust with an egg wash and sprinkle with salt. An egg wash makes a nice golden sheen on the crust. Full disclosure: we were out of eggs and had to brush on heavy cream to the crust for these photos (a substitute for an egg wash). You can tell it doesn’t have quite the sheen as the crusts in our other galette recipes! So an egg wash is the way to go.

Serving this mushroom galette

Once you bake up your mushroom galette, don’t dig into it just yet! The cooling time is important for achieving the best texture. Here’s what to know:

Storage info

Got leftovers of this mushroom galette? Place it in a storage container and refrigerate for up to 3 days. You can also make it 1 day in advance: bake it, then refrigerate over night. Before serving, leave it out on the counter for about 30 minutes to let it come to room temperature. If desired, reheat it in a 350 degree oven until warmed through.

This hearty mushroom galette is a tasty savory tart recipe bursting with flavor! This vegetarian dinner idea will wow everyone.


For the galette dough 

  • 1 ½ cups [210 grams] all-purpose flour, spooned and leveled
  • ¾ teaspoon kosher salt
  • ¼ teaspoon baking powder
  • 10 tablespoons cold unsalted butter
  • 5 to 6 tablespoons cold water
  • 1 egg, for the egg wash
  • Flaky sea salt, for sprinkling

For the filling

  • 16 ounces cremini mushrooms, cleaned and sliced
  • 4 ounces shiitake mushrooms, stems removed and sliced
  • 2 tablespoons olive oil
  • 1 tablespoon soy sauce (or tamari)
  • 2 teaspoons garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon smoked paprika
  • ½ teaspoon dried thyme
  • ¾ teaspoon kosher salt, plus more to sprinkle
  • ¾ cup whole milk ricotta
  • ½ cup shredded Parmesan cheese
  • 1 small garlic clove, grated
  • Fresh ground black pepper
  • 2 sprigs fresh thyme, for topping


  1. In a medium bowl, mix the flour, kosher salt, and baking powder. Slice the butter into small pieces, then use a pastry blender or fork to cut it into the flour mixture until mostly incorporated and a pebbly texture forms (with pea-sized or smaller pieces).
  2. Sprinkle 4 tablespoons of the cool water over the flour, mixing gradually with a fork until the flour is mostly incorporated. Add the additional 1 to 2 tablespoons of water until all the flour is incorporated, kneading with your fingers until the dough comes together. (Resist the urge to add more water; it should come together!) Form the dough into a ball and flatten into a thick disk. Wrap it in plastic or place it in a covered container and chill the dough for 1 hour. (To make in advance, you can refrigerate the dough up to 3 days; allow to sit at room temperature 30 minutes before rolling. Or, wrap in plastic wrap or aluminum foil and freeze up to 3 months, then defrost overnight in the refrigerator before rolling.)
  3. Preheat the oven to 400 degrees Fahrenheit.
  4. Clean and slice the mushrooms. Toss them in a bowl with the olive oil, soy sauce, garlic powder, onion powder, smoked paprika, thyme, and ½ teaspoon kosher salt. Place them in a single layer on a parchment lined baking sheet and bake for 20 minutes until tender.
  5. In a medium bowl, mix the ricotta cheese, Parmesan cheese, garlic, ¼ teaspoon kosher salt, and a few grinds black pepper. 
  6. On a floured surface, roll the dough into an even 12” circle, leaving the edges rough (if needed, move the dough around and add a bit more flour underneath to keep it from sticking). Carefully transfer the dough to a sheet of parchment paper on a rimmed baking sheet. 
  7. Gently spread the ricotta mixture on the dough, then add the mushrooms, leaving at least 2 inches of dough around the outside edge. Fold in the outside edges of the dough over the filling to form an approximately 2-inch crust, overlapping the folds as shown in the photos. Top with fresh thyme leaves.
  8. Whisk the egg and use a pastry brush to brush it onto the crust. Then top the crust with a small sprinkle of flaky sea salt. 
  9. Bake the galette for 30 to 33 minutes until the crust is golden brown. Remove from the oven and transfer the parchment paper to a baking rack to cool. Cool for at least 10 minutes, then slice into pieces and serve. It’s also great at room temperature or cold. Store leftovers for up to 3 days refrigerated; bring to room temperature or warm in the oven before serving.

This portobello sandwich stars a mix of roasted portobello mushrooms, crunchy veggies, and creamy horseradish sauce. It’s to die for!

Portobello Sandwich

Here’s a slam dunk for mushroom lovers, or anyone looking for a meaty vegetarian sandwich. Try this Portobello Sandwich! It’s modeled after a steak sandwich, but instead the filling is juicy roasted portobello mushrooms, seasoned with garlic, soy sauce and smoked paprika. Add to that crunchy pickles and onions, and the kicker: a horseradish sauce that smothers it all with a creamy, spicy tang. You’ll become a believer after your first bite!

What’s in this portobello sandwich?

You can build a portobello sandwich with many different flavor profiles. In fact, a Portobello Burger is a prime example of a classic spin on one. For this one, we took inspiration from a steak sandwich, infusing the roasted portobello mushrooms with smoky, savory spices and topping it off with a horseradish sauce. Here’s what you’ll need for this recipe:

  • Portobello mushrooms
  • Olive oil
  • Soy sauce (or tamari)
  • Garlic
  • Smoked paprika, onion powder and salt
  • Worcestershire sauce
  • Artisan buns
  • Baby arugula or greens, pickles, and white onion , for serving
  • Horseradish sauce, for serving
Portobello Sandwich

How to make roasted portobello mushrooms

The filling for this sandwich is not a whole portobello mushroom like in a Portobello Burger, but sliced mushrooms. The advantages? The sandwich is much easier to eat than trying to pull bites off of a big juicy portobello. It also makes for a taller sandwich, which is more aesthetically pleasing and has more mushroom flavor. Here’s the basic idea around how to make roasted portobello mushrooms:

  • Preheat the oven to 450 degrees Fahrenheit. Mushrooms roast best at very high heat.
  • Slice the portobello caps into 1/4-inch thick slices and season. Add olive oil and spices. We’ve found the combination of soy sauce, Worcestershire, garlic and smoked paprika makes an intensely savory, meaty flavor.
  • Roast for 15 minutes. That’s it! The mushrooms come out juicy and tender.

Don’t skip the sauce

This portobello sandwich highlights mushrooms, of course. But the other star who’s vying for attention? The horseradish sauce! This sauce is so full of creamy, savory flavor, it almost steals the show. Look for prepared horseradish in the condiments section of your local grocery, then you’ll need sour cream, mayo, Dijon mustard, vinegar, and chives. It’s simple and lasts for 2 weeks, and you can use it on just about anything: a fries dip, salads, and more.

Horseradish Sauce

Ways to serve this portobello sandwich

One thing to note about this portobello sandwich: because it’s based around mushrooms, it doesn’t have lots of protein. So when you serve this sandwich, make sure to serve with other proteins to make it into a complete meal. Here are some ideas:

The post Umami Rice Stacks with Vegan Caviar appeared first on My New Roots.

It hasn’t happened in so long; when an idea hits like a bolt of lightening, and a recipe is downloaded perfectly into my brain, complete and fully-baked: Umami Rice Stacks with Vegan Caviar. I was talking to a dear friend a couple weeks ago, about nothing related to food, and this random idea for vegan caviar popped into my head. Out of nowhere. Understanding how my creative self works, I had to say this idea out loud immediately so I wouldn’t forget. No sooner had the words chia and kelp come out of my mouth, then the rest of the recipe tumbles out, one element after the next until it was there: a crispy rice, caviar-studded, spicy, creamy, savoury, stack with carrot-kimchi salad, avocado, and sesame. If you’re familiar with “sushi pizza” you’ll get where I’m going with this! 

Although the entire dish is absolutely delicious, my favourite part has to be vegan caviar. It’s so easy to make and really fun! I knew that it had to have an “ocean-y” flavour, so using a sea veggie made the most sense. Nori is widely available and is a mild seaweed that most people enjoy the taste of, so I went with that. I used a product called nori “krinkles” that are minimally-processed kelp (just dried and toasted), but if you can’t find those, use nori flakes, or a couple sheets of sushi nori instead. After soaking for a minute, the nori becomes soft and easy to blend, and with the addition of tamari, a salty, umami-bomb liquid ensues – perfect for soaking the chia in! 

After 15 minutes, the chia absorbs all of that dark, delicious liquid, and swells up to resemble teeny tiny eggs…BOOM! Vegan caviar is born! I added a touch of olive oil to create a slick mouthfeel too – this is optional, but pretty effective. And the “chaviar” continues to absorb the liquid it’s in while hanging out in the fridge, so to make it the right consistency, I just drizzle in a little water before serving each time. I’m over the moon about this one, people! 

Sea Vegetables

Sea vegetables, like the nori used in this recipe are abundant, incredibly nutritious, eaten world-wide, and a truly nourishing food. Sea vegetables come in all different colours: red, brown, green, blue, and more and can be grown in the sea or cultivated in tanks. They have a smaller carbon footprint than the veggies we know and love that grow on land and don’t rely on the soil which globally needs restoring and rejuvenation!

Kind of like the sprouts of the ocean, packing so many nutrients in a small amount of food — they are actually the most nutrient-dense food on the planet, how rad is that? These rainbow-coloured, unassuming, under-water plants contain protein, various vitamins, important iodine (for thyroid health!), fiber, calcium, iron, and more, often times in much higher concentrations than their land veggie or even animal-food counterparts. Shining stars of the sea, the micronutrient content is just unparalleled especially as our soil nutrients continue to decrease due to degenerative farming practices. Holistic, regenerative agriculture works to combat soil nutrient loss and I highly recommend you seek out your local farmers trying to bring life back to the soil in your area and in the meantime, try incorporating more sea veggies into your daily diet. 

Some of the most common sea vegetables:

A great source of calcium (more than other sea veggies) and vitamin A. Sweet and mild, perfect for beginners and because of the fiber, Arame is great for digestion! 

Folate-, manganese-, and iron-rich wakame is a sweet kelp that’s often found in salad form! 

Handy in a pot of beans to enhance digestibility, and as a flavour and mineral-enhancer in broths, kombu is high in magnesium and potassium. 

Likely the most common sea veggie because of the popularity of sushi, you can find nori in krinkles, sheets, or flakes, dried or toasted! This is an easy and accessible way to eat more seaweed! 

You’ve probably seen the brightly-blue-hued smoothies coloured by this algae. Just 1 Tbsp. of spirulina has as much protein as a small handful of almonds and an impressive amount of iron. 

A beautiful red seaweed, with ample amounts of magnesium and calcium. 

There are countless more but these are the ones most commonly used in my recipes and are generally readily available! There are some concerns for sensitive populations about seaweed’s ability to store heavy metals when grown in polluted water. It’s important to find brands that are conscious about their sourcing, aren’t over-harvesting or are growing responsibly, and make sure you eat in moderation. I do think we all could benefit from diversifying our diets a little more to include these incredible superstars. 

Now back to the recipe!

The first layer of this dish is the rice bottom, and that is what I cooked first (after nailing the chaviar). I tried using a couple of types of brown rice here, but I only found success was the short grain, I’m guessing because it has a more glutinous consistency than long grain and basmati, which tend to be lighter and fluffier. When I tested with the latter, I had to use an egg to bind the ingredients, but desired a vegan final product, so wound up using short grain in the end. You can absolutely use white rice if you like, but keep in mind that brown rice still has the bran intact and therefore more fibre, vitamins, and minerals. 

Since my inspo was sushi pizza, I wanted a super crispy rice base. A quick sear in a hot pan was great, but without deep frying, I couldn’t get the satisfying crispiness that I desired. I’ll leave it up to you whether or not you take this extra step. I bet an air fryer would work beautifully here! The rice is still good even if it’s cold or room temperature, and a lot less fussy. Either way, make sure to cook the rice at least 4-5 hours before serving, so that it has time to cool down, so you can cut it into your desired shape. I used a jar lid for this, but a drinking glass or other circular tool would work perfectly. 

The kimchi-carrot salad was inspired by the spicy salmon that often crowns a sushi pizza – it’s savoury and moreish, with a consistency walking the fine line between and al dente and tender. I steamed the carrots to achieve this texture, and you can cook them as little or as much as you like depending on your preference! The end result was so close to raw fish that my husband has a hard time believing it was carrots at all. Smothered in a creamy, brine-y, funky sauce, these humble roots become uniquely surprising and remarkably flavourful. 

Don’t be intimidated by the multiple components of the Umami Rice Stacks with Vegan Caviar – once the rice is cooked and cooled, the rest comes together pretty quickly. You can even watch me make it in a live class on my wellness platform, My New Roots Grow! Perhaps bookmark this dish for a special occasion or celebration, so that you’ll set aside the time to make it. When tackling something new and different, I make sure I have ample hours so I don’t feel rushed. Cooking under pressure is the worst! Give yourself the gift of slow kitchen creation time. 

Now for some notes on the Umami Rice Stacks with Vegan Caviar recipe…

I would encourage you to use short grain brown rice here (as I mentioned above) because it is the most glutinous and sticky, and it holds together well when you’re making that little base for the toppings. But! If long grain brown or brown basmati is all you have available, no worries. You may need to skip the cut-out step, and instead make a little pile on your plate. It’s all going to same place and tastes great no matter what format it takes! Haha…

If you have the the time for it, soak the rice overnight or for 8-12 hours in plenty of filtered water with a little splash of apple cider vinegar or lemon juice added. This improves the digestibility of the rice, and cuts back a little on cooking time too. 

The amount of water you’ll use to cook the rice in depends on whether or not you’ve soaked the rice, and the size of the pot, so keep an eye on it, and add water as needed. You want the rice on the wetter side of things, since it’s the moisture in it that is going to help hold it together. Mirin, a sweet rice wine, is a tasty addition here, but it can be substituted with rice wine vinegar and a pinch of your sweetener of choice, or omitted altogether.

Umami Rice Stacks

  • 1 cup / 200g short grain brown rice
  • 2 ¾ cups / 650ml filtered water
  • ¾ tsp. fine sea salt
  • 1 Tbsp. mirin optional, but delicious


  • ½ cup / 125 ml nori too light to have a gram measure
  • sub with 3 sheets of sushi grade nori
  • ½ cup / 125ml hot water more as needed
  • 1 tsp. tamari or soy sauce
  • 2 Tbsp. chia seed
  • 1 tsp. olive oil

Kimchi Mayo

  • ¼ cup / 40g kimchi finely chopped
  • 1 Tbsp. sriracha
  • cup / 85ml mayonnaise vegan or egg-based
  • ¼ tsp. ground chili to taste
  • ½ tsp. toasted sesame oil

Carrot-Kimchi Salad

  • 3 medium / 300g carrots
  • 2 tsp. tamari or soy sauce
  • 2 tsp. freshly-squeezed lemon juice
  • 2 tsp. cold-pressed olive oil
  • ½ Tbsp. finely grated ginger
  • 1 batch kimchi mayo recipe above

For Serving

  • 1 ripe avocado
  • 2-3 spring onion
  • 1 Tbsp. toasted black sesame seeds


  • Start by soaking the rice (see headnotes). Drain and rinse well, then place in a cooking pot with 2 ½ + cups / 625ml +  water, plus the salt. Bring to a boil, reduce to simmer, and cook covered for about 35-40 minutes if soaked, 45-60 minutes if cooked from raw. Check the water levels periodically to make sure the pot isn’t drying out, and add water to the pot if necessary. When the rice is cooked, remove the lid and let cool for a few minutes. Add the mirin, and fold to combine.
  • Prepare a standard brownie pan (8×8” / 20x20cm) by rubbing it with a little fat to prevent sticking (olive oil, expeller-pressed coconut oil, ghee, or butter). Press the rice firmly into the pan, making it as level and even as possible. Place in the fridge for at least 4 hours, or overnight. 
  • Make the chaviar by combining the nori with water from a recently-boiled kettle. Let soak for 1-2 minutes, then add the tamari and transfer this mix in a blender (or use an immersion blender). Blend on high until smooth. Transfer mixture to a jar, then stir in the chia seeds. Let the chia absorb the liquid, stirring occasionally. Set aside. 
  • Make the kimchi mayo by stirring the ingredients together in a small bowl.
  • Scrub the carrots well, and chop them into your desired size – just make sure that they are relatively similar and bite-sized so that they cook evenly. Place in a steamer basket in a pot with water and set to medium-high heat, cover, and cook for 4-8 minutes once steaming – depending on their size and your preference. While the carrots are steaming, whisk together the tamari, lemon juice, olive oil, and grated ginger in a medium bowl and set aside. The carrots are ready when they are tender. Remove from heat, and immediately add to the bowl with the marinade. Stir well to coat. Let cool.
  • While the carrots are cooling, cut the rice out into your desired shapes. I used a jar lid (see photo) that would create four equal-sized portions, but you can also just cut the rice slab into four squares as well (alternatively, make a bunch of small, bite-sized pieces for appetizers!). 
  • Place the rice bases on your plates. Spread a dollop of the kimchi mayo on top of each base and spread it to the edges. Top with avocado slices, then a few spoonfuls of the chaviar on top. Fold the remaining mayo through the marinated carrots, then spoon those on top of the avocado. Sprinkle with finely sliced spring onions and sesame seeds. Say thank you and enjoy immediately.
