what are scalloped potatoes?

I used to think that the term “scalloped” referred to the cut of the potatoes, but it doesn’t. Scalloped potatoes are potatoes that are sliced thinly and baked in a sauce made of cream infused with herbs and spices. This dish could also be called Potatoes Au Gratin because it is topped with cheese rather than simply baked with cream. But whatever you call them, these creamy scalloped potatoes with thyme will be your new favorite! They have a fancy feel to them and definitely fit in nicely on a holiday table. But we love them so much, I often serve them for Sunday lunch.

Ingredients for Scalloped Potatoes

Ingredients for creamy Scalloped potatoes with thyme

The ingredient list is pretty simple. In fact, you may have everything you need in the pantry right now to get started! You’ll need:

  • 4 lbs Russet or Yukon Gold Potatoes
  • 4 Tbsp Unsalted Butter
  • 1/2 Cup Diced Yellow Onion
  • 3/4 tsp Garlic Powder
  • 1/4 tsp Black Pepper
  • 2 Tbsp Fresh Thyme or 2 tsp Dried Thyme
  • 1/4 Cup All Purpose Flour
  • 2 Cups Chicken Broth
  • 2 Cups Heavy Cream
  • Salt to Taste
  • 2 1/4 Cup Shredded Cheddar Cheese
  • 1/2 Cup Parmesan Cheese
butter and onion
homemade cream of onion soup


You can use Russet Potatoes or Yukon Gold Potatoes for this recipe, but other varieties such as Red Potatoes and Fingerling Potatoes will NOT work because they won’t get tender enough when baked.

The Heavy cream CAN be subbed out for milk, half and half, or a milk alternative. But a sub with less fat content will produce a less creamy end result.

You can use shredded or grated parmesan cheese instead of shaker parmesan.

To make ahead

This dish can be made ahead to save time! To do this, simply bake as instructed, let it cool completely on the counter, then cover it tightly with foil and refrigerate overnight. On the day of, take it out of the fridge and let it sit on the counter for 30 minutes. (Don’t place a cold casserole dish in a hot oven!) Then, leave covered and heat at 350 degrees for 30 minutes, or until warm and bubbly!

Can I sub milk for the heavy cream?

You can! You can do any combination of cream, half and half, milk, or milk alternative. However, the potatoes are MOST creamy and rich with the heavy cream and the sauce will be thinner with a lower fat liquid.

Can I Omit the thyme?

You can omit the thyme and still get a great potato casserole, but the thyme is really the star of the show. If you don’t want such a strong flavor you could half the amount called for in the recipe. But the thyme is what gives this such an earthy and delicious flavor!

Can I make these Gluten Free?

Absolutely! You can just sub your favorite gluten free All Purpose flour in place of the regular All Purpose when making the sauce. I like using Bob’s Red Mill Gluten Free 1- to- 1. You could also use Tapioca Starch as a 1- to-1 replacement for flour.

    1. I would think you could safely do half of the cheese melted in. If you did all of it, it might end up too thick… if you try it, please report back and let me know if it works!

    Taste is delicious, but there’s unfortunately no temperature to set this dish at. I did 350 for the states time since that is stated in the “make ahead” directions. Took an additional 25 minutes to cook completely beyond the hour and ten minute stated time. Maybe I needed a higher degree?

    1. Thank you for your patience! I’m so glad you enjoyed the taste. I’m sorry about the missing oven temp! I’ve updated the recipe card. In the future, set the oven to preheat at 375 and it should bake perfectly!
