How to Make Scalloped Potatoes?
Follow these simple, detailed steps to create a classic scalloped potatoes recipe with cheese that beginners and seasoned cooks alike will love:
1. Prep the Potatoes

- Peel and Slice: Peel the Yukon Gold potatoes and slice them uniformly about 1/8-inch thick using a mandoline slicer. Uniform slices are key to an even bake.
- Optional Parboiling: For extra tender potatoes, place the slices in a pot of salted water. Boil for 2–3 minutes until they’re just starting to soften, then drain and set aside. This step helps prevent underdone potatoes and ensures they absorb the creamy sauce evenly.
2. Make the Cream Sauce

- Sauté Aromatics: In a 2-quart saucepan, melt 3 tablespoons of unsalted butter over medium heat. Add the thinly sliced onion and minced garlic; sauté until the onion is translucent and fragrant.
- Form a Roux: Sprinkle in 1 tablespoon of all-purpose flour and whisk constantly for about 1 minute. This step thickens the sauce without lumps.
- Add Dairy: Gradually pour in 2 cups of heavy cream and 2 cups of whole milk while whisking continuously. Stir in the fresh thyme, salt, pepper, and nutmeg.
- Simmer Gently: Bring the mixture to a gentle simmer. Allow it to cook for 2–3 minutes until slightly thickened. Do not let the sauce boil; high heat may cause curdling.
3. Assemble the Scalloped Potatoes
- Layering: Preheat your oven to 375°F. Generously butter your 3-quart baking dish. Start by layering one third of the potato slices at the bottom. Pour a portion of the warm cream sauce evenly over the potatoes, then sprinkle a third of the Gruyère cheese.
- Repeat Layers: Continue layering the remaining potato slices, sauce, and cheese. Aim for 3 even layers, ensuring every slice is well-coated with the creamy mixture.
- Final Touch: For a beautiful finishing touch, sprinkle a few extra thyme leaves over the top.

4. Bake and Broil
- Bake Covered: Cover the dish loosely with aluminum foil and bake for 35–40 minutes. This initial baking ensures that the potatoes cook evenly and absorb the flavors.
- Uncover and Broil: Remove the foil and switch your oven to the broil setting. Broil for an additional 3–5 minutes until the top is bubbly and golden brown.
- Rest Before Serving: Let the dish cool for about 15 minutes. This rest period allows the sauce to thicken slightly, making serving easier and enhancing the creamy texture.

Tips for Perfect Scalloped Potatoes
Although these creamy scalloped potatoes are simple to make, but to up your your homemade scalloped potatoes game and master the recipe, you can follow my tried and tested tips:
- Choose the Right Potatoes: Russet or Yukon Gold are ideal because they hold their shape yet become perfectly tender.
- Thin & Even Slices: Use a mandoline or a sharp knife for consistent thickness. This ensures even cooking.
- Don’t Skimp on Seasoning: Season each layer of potatoes with salt and pepper to enhance flavor throughout.
- Make Ahead for Holidays: Assemble everything a day in advance, cover, and keep it in the fridge. Then bake when you’re ready to serve.
- Variation Alert: For a quick “Au Gratin” twist, add extra cheese between layers and even a sprinkle of grated Parmesan on top.
