  • Potatoes: Thinly sliced potatoes speed up the baking process. I typically will use starchier Russet potatoes since I prefer a creamy scalloped potatoes.
  • Butter: Salted or unsalted butter will work.
  • Garlic: Minced garlic is best!
  • Flour: All-purpose flour thickens the dairy mixture and makes a creamier sauce.
  • Milk: Any type of milk will work well with the cheese and flour mixture. I like whole milk or half and half, for a richer, thicker and creamier sauce.
  • Cheese: Freshly grated sharp cheddar cheese is what I used. Thick grated cheese is best for a cheesier casserole.
  • Garnish (optional): Fresh thyme, parsley or even Parmesan cheese can be used.

Best Potatoes To Use

For scalloped potatoes, Russet or Yukon Gold potatoes are the best choice. Russets are starchier, which helps create an extra creamy sauce, while Yukon Golds are naturally buttery and hold their shape nicely. You can use either one or even a mix of both for the perfect balance of texture and flavor.

Recipe Tips

  • Use a mandoline: The key is to make sure your potato slices are super thin in this cheesy scalloped potato recipe. Each slice should be about 1/8″ thick.
  • Extra cheesy: For the best taste, grate your own cheddar cheese. When it’s freshly grated, it makes it creamy and bubbly on top.
  • Room temperature milk: When adding milk to the roux to prevent heat shock and possible curdling, bring it to room temperature first before making the cream sauce.
  • Cut down on cooking time: To speed up the cooking time of the cheesy scalloped potatoes, pop them into boiling water to par boil for just a few minutes then drain well.
  • Creamier: Use heavy cream for the best rich tasting cheesy scalloped potatoes!

FAQs

What if the potatoes aren’t tender when the baking time is done?

Sometimes scalloped potatoes need a little extra time in the oven to soften fully. If the cheese has already browned but the potatoes are still firm, simply cover the dish back up with foil and continue baking in 10-minute increments until they’re tender.

Can I make cheesy scalloped potatoes ahead of time?

Yes! Assemble the potatoes, cover with foil, and bake for 30 minutes. Let cool, then refrigerate overnight. Before serving, bring to room temperature for 30 minutes, then bake uncovered for 20–30 minutes, until tender and bubbly.

How do I store leftovers?

Store leftovers in an airtight container in the refrigerator for 3–5 days. For best results, reheat gently on the stove or in the oven to keep the sauce from separating.

Can you freeze scalloped potatoes?

I don’t recommend freezing, since the creamy sauce and potatoes can change texture once thawed.
