What are Potatoes Au Gratin?

Potatoes au gratin are basically scalloped potatoes with cheese (haha, that made me think of “royale with cheese”). So if you like scalloped potatoes and you like cheese, you’ll LOVE potatoes au gratin!

If you’ve never had scalloped potatoes, you can think of potatoes au gratin like this: thinly sliced potatoes layered with cheese and a creamy white sauce, then baked until bubbly and delicious. It’s pretty incredible.

What Kind of Cheese Can I Use?

In general, you want to stick to smooth melting cheeses for potatoes au gratin and avoid hard aged cheeses that don’t melt as easily (like Parmesan, although that would make a nice topper mixed with breadcrumbs!). I had some cheddar cheese on hand today, that I used, but Gruyere is another popular choice for potatoes au gratin.

What to Serve with Potatoes Au Gratin

This is such a rich comforting dish that it pairs well with any roasted or baked comfort food. I would pair it with something like Herb Roasted Pork Tenderloin, Cheddar Cheeseburger Meatloaf, or Herb Butter Chicken Thighs. And of course you’ll probably need some sort of vegetable to balance out all that richness, so add a simple side of steamed green beans for good measure. ;)

What Kind of Potatoes are Best?

Most people like a waxier variety for potatoes au gratin, like Yukon gold or red potatoes, but I’m the opposite. I like russet potatoes because they are starchier, which helps keep the sauce nice and thick, and I enjoy how soft they get when baked in the creamy sauce. If you prefer a more firm slice, go with Yukon gold or red potatoes.

It’s not even Halloween yet, but it’s never too early to start planning for Thanksgiving, so I’m going to throw you this little tip to save for later. There are so many moving parts that go into making sure a Thanksgiving meal is hot and ready all at the same time, and it’s even more challenging when you’re working with just one stove. Recipes like these Slow Cooker Mashed Potatoes that can be prepared on the side will free up space on your stove top and, because it requires no babysitting, will leave your hands and eyes free to focus on other recipes. Thanksgiving Day boil-over averted. 😅

Why Make Mashed Potatoes in a Slow Cooker?

Using the slow cooker cuts out the “babysitting the boiling pot” step in the process of making mashed potatoes, which can really free you up to concentrate on the rest of your meal. It also eliminates boil overs, draining the potatoes, constantly checking them with a fork to see if they’re tender, using multiple pots and dishes, and gives you another free burner on your stove top. With slow cooker mashed potatoes, you just add everything to the pot and press a button and go. And if you can’t get to them right when the timer goes off, they’ll be okay!

How Do You Flavor Mashed Potatoes?

I flavored my mashed potatoes with garlic, pepper, butter, milk, and cream cheese, but you can use your tried and true favorite mashed potato add-ins with this recipe. The cooking process will stay the same: 3 lbs. potatoes and about 1.5 cups of broth. Then after they’re cooked, add in whatever you’d like! My All-Purpose Garlic Herb Seasoning is a favorite, but other fun seasoning blends include Everything But The Bagel Seasoning, or even ranch seasoning.

What Kind of Potatoes are Best for Mashed Potatoes?

Russet potatoes are my top choice for mashed potatoes because they have a light, fluffy flesh. You can use red potatoes, but they tend to create a more dense mashed potato.

Can I Make Them Vegetarian?

Absolutely! You can swap the chicken broth listed in the recipe below for vegetable broth. Just be aware that vegetable broth is usually a much darker color, so your finished mashed potatoes may look a little more brown.

What Size Slow Cooker Do I Need?

I’m using a 5 quart slow cooker, but it was only about half full, so you could probably get away with using a 3 quart slow cooker for this recipe.

Ingredients

  • 3 lbs. russet potatoes $1.80
  • 1.5 cups chicken broth $0.20
  • 2 cloves garlic, minced $0.16
  • 1/4 tsp Freshly cracked black pepper $0.05
  • 4 oz. cream cheese $0.40
  • 1/2 cup milk $0.25
  • 1 Tbsp butter $0.13

Instructions

  • Wash and peel the potatoes, then dice them into one-inch cubes. Rinse the diced potatoes with cool water in a colander to remove the excess starch.
  • Add the cubed potatoes, minced garlic, chicken broth, and some freshly cracked pepper to the slow cooker. Stir briefly to distribute the garlic and pepper.
  • Place a lid on the slow cooker and cook on high for three hours, or until the potatoes are fork tender. You can test the tenderness by lifting the lid just long enough to pierce the potatoes with a fork.
  • Take the lid off the slow cooker and add the cream cheese, milk, and butter. Stir to combine the ingredients and mash the potatoes. For an extra smooth mashed potato, use a hand mixer to briefly whip the potatoes until smooth.
  • Taste the potatoes and add salt or pepper if needed. Serve immediately, or switch the slow cooker to the "warm" setting until ready to serve.
