About the Ingredients
Russet Potatoes
High starch content ensures tender, fluffy layers that absorb the sauce beautifully.
Onion
Adds a subtle sweetness and depth of flavor.
Butter & Flour
Form the base of a classic roux, creating the creamy cheese sauce.
Milk
Provides creaminess and binds the sauce. Whole milk or even half-and-half delivers the best results.
Cheddar Cheese
Melts smoothly and adds sharp, bold flavor.
Parmesan Cheese
Adds nutty, salty notes and a golden crust on top.
Garlic Powder & Paprika
Seasonings that enhance the flavor without overpowering the potatoes.
Salt & Pepper
Essential for balancing flavors.
Tips & Tricks
Even Slicing
Slice potatoes evenly thin (about ⅛-inch) to ensure they cook uniformly.
Extra Creaminess
For extra creaminess, use a mix of whole milk and heavy cream.
Cheese Shredding
Shred cheese from a block rather than using pre-shredded cheese, which often contains anti-caking agents that affect melting.
Pro Tips
- Cover with foil for the first baking phase to keep the potatoes tender, then uncover to achieve a golden crust.
- Let the dish rest for 10 minutes after baking—this allows the sauce to thicken before serving.
- Use a mandoline slicer for perfectly even potato slices.
Step-by-Step Instructions
Preheat and Prepare
Set your oven to 350°F (175°C) and grease a 9x13-inch baking dish to prevent sticking and ensure easy serving.
Create the Roux
Melt butter in a saucepan over medium heat. Add the finely chopped onion and cook until softened. Stir in the flour, garlic powder, salt, and pepper to form a roux, which is the base of your creamy sauce.
Add Milk and Thicken
Gradually whisk in the milk, ensuring it is fully incorporated. Continue to cook the mixture until it thickens and begins to bubble, creating a smooth, creamy sauce.
Incorporate Cheese
Remove the saucepan from heat and stir in the shredded cheddar cheese until the sauce is smooth and velvety.
Layer Potatoes and Sauce
Arrange half of the sliced potatoes in the prepared baking dish, then pour half of the cheese sauce over them. Repeat with the remaining potatoes and sauce to ensure every slice is coated.
Finish and Bake
Sprinkle Parmesan cheese and paprika over the top for a flavorful crust. Cover the dish with foil and bake for 45 minutes. Remove the foil and bake an additional 30 minutes until the top is golden and bubbly.
Rest and Serve
Allow the dish to rest for 10 minutes before serving to let the sauce thicken further and enhance the texture.
Delicious Variations
Add Protein
Mix in cooked ham, bacon, or shredded chicken for a heartier meal that transforms this side dish into a main course.
Different Cheeses
Try Gruyère, Swiss, or Monterey Jack for unique flavor profiles that can elevate the dish.
Spicy Kick
Add red pepper flakes or diced jalapeños for heat if you prefer a spicier version of scalloped potatoes.

Frequently Asked Questions
Can I make scalloped potatoes ahead of time?
Yes! Prepare the dish, cover tightly, and refrigerate up to 24 hours before baking. Add 10–15 minutes to the bake time if chilled.
Can I use Yukon Gold potatoes instead of russet?
Absolutely. Yukon Golds have a creamier texture and hold their shape well, making them an excellent alternative.
What’s the difference between scalloped potatoes and au gratin potatoes?
Scalloped potatoes typically use a creamy sauce, while au gratin potatoes add breadcrumbs and extra cheese layers for a crispier topping.
How do I prevent my sauce from curdling?
Ensure you gradually add the milk and stir continuously to maintain a smooth texture. Avoid high heat which can cause separation.
Can I add vegetables to the recipe?
Yes, you can add vegetables like spinach or broccoli for added nutrition and flavor.
