Potatoes Au Gratin are incredibly creamy, cheesy, thinly sliced potatoes packed full of flavor. When you make them in stacks, they’re easy to serve and each portion is perfectly crusted at the edges! It’s a fun twist on Gratin Dauphinoise!

They’re easy, beautiful and have luxurious flavor! They’re easy enough to make on a weeknight, but delicious enough to serve at your next dinner party.

They freeze well so you can make a batch, freeze and enjoy as a simple side dish when you just need a few servings! The potatoes are perfectly softened through with lots of great texture from the browned edges of each serving – oh-so-delicious!

Potatoes, cream and cheese are slow baked to perfection in individual muffin tins to soak up all the creamy goodness. I think you’re going to love these potatoes, so let’s get started!

Ingredients and Substitutions

  • Potatoes – Russet potatoes are the best to use for these Potato Gratin stacks. Peel and slice thin (a mandoline makes this task a breeze).
  • Cheese – White cheddar, gruyere, Monterey jack, mozzarella are all delicious options. I use a blend of white cheddar and gruyere.
  • Milk and Heavy Cream – Use all heavy cream or a mix using the heaviest milk you have on hand.
  • Salt and Pepper – Fresh cracked sea salt and ground pepper add texture and flavor.
  • Leeks – Completely optional, but highly recommended! Leeks are in the onion, garlic, shallot family adding amazing flavor. Select leeks that have as much white/light green stem as possible. Remove roots and thinly slice stem.
  • Jalapeño – To give this side dish a hint of spice.

How to Make Potato Gratin Stacks

Tips

  • Need help with converting this recipe into more or less servings? Check out my Essential Measurement Conversion Chart or use the yield tab in the recipe card.
  • While a mandoline makes slicing the potatoes so easy, you can slice by hand. Just be patient and make the slices as consistent as possible.
  • When cooked perfectly, your potatoes should have no resistance as you cut in to serve. Check the resistance by slicing a knife through the center of one stack. Bake longer if they aren’t quite finished at 40 minutes.
  • Remove from the muffin tin by gently scooping with a small spatula at the base of each stack.

Frequently Asked Questions

Can you reheat au gratin potatoes?

Yes! Simply heat your oven to 375 degrees, cover with foil, and reheat for around 45 minutes to ensure they are warmed through. (Remove foil during the final 10 minutes of baking.)

Are scalloped potatoes and au gratin potatoes the same thing?

The key difference is cheese! Scalloped potatoes are made without cheese, while au gratin potatoes use cheese to create the creamy sauce. Scalloped potatoes also tend to be sliced a touch thicker than au gratin potatoes.

Best Potatoes for Gratin

Russet or any kind of “dirt” potatoes work well for gratin dishes. Russet potatoes are tender thanks to their starch making them ideal for gratin.

Make Ahead

Slice potatoes, make sauce reserving 1/2 cup, toss, fill muffin tins and cover tight with plastic wrap to prevent potatoes from browning and refrigerate. Add remaining sauce and bake just before serving.
