- Russet potatoes: Peeled and sliced thin for tender texture that holds up well during baking.
- Yellow onion: Adds a subtle sweetness and aroma that complements the richness.
- Unsalted butter: Essential for a silky cheese sauce base without overpowering saltiness.
- All-purpose flour: Thickens the sauce, giving it a luscious creamy texture.

How to Make Cheesy Scalloped Potatoes Recipe
Step 1: Preheat and Prepare Your Baking Dish
Start by heating your oven to 400°F and lightly greasing an 8x8-inch casserole dish with nonstick spray. This ensures everything cooks evenly without sticking, setting the stage for your delicious layers.
Step 2: Layer Potatoes and Onions
Arrange your peeled and sliced russet potatoes alongside rings of yellow onion in the dish. Stagger them for even distribution of flavors and to keep the layers visually appealing. This layering is crucial for the flavors to mingle and for the cheese sauce to soak into every nook.
Step 3: Make the Cheese Sauce
In a medium saucepan over medium heat, melt the butter and whisk in flour and kosher salt. Cook this mixture for about one minute, stirring constantly—it forms a roux that thickens your sauce to perfection. Slowly add the whole milk while whisking to avoid lumps, and cook until the sauce thickens beautifully.
Step 4: Melt in the Cheese
Add the shredded mild cheddar cheese all at once into your thickened sauce. Stir continuously until it's completely melted and smooth—this creates the luscious, cheesy envelope that coats your potatoes with every spoonful.
Step 5: Combine and Bake
Pour the cheesy sauce evenly over your layered potatoes and onions, making sure every slice gets a good soak. Cover the dish tightly with aluminum foil and bake in your preheated oven for 85 to 90 minutes, or until the potatoes are fork-tender and infused with that creamy goodness.
Step 6: Broil for a Golden Finish
For that irresistible crisp and golden top, switch your oven to broil once the baking time is complete. Broil just long enough for the top to turn beautifully golden brown—keep a close eye on it here to avoid burning. Finally, season with salt and pepper to taste before serving.
How to Serve Cheesy Scalloped Potatoes Recipe
Garnishes
Fresh herbs like chopped parsley or chives sprinkled on top right before serving add a pop of color and a bright note that balances the richness. A light dusting of extra cheddar or a sprinkle of paprika can also elevate the presentation and flavor.
Side Dishes
This Cheesy Scalloped Potatoes Recipe pairs wonderfully with roasted vegetables, a crisp green salad, or simply alongside your favorite protein like roasted chicken or grilled fish. The creamy potatoes are substantial enough to be a star side that complements a variety of mains beautifully.
Creative Ways to Present
Try serving these scalloped potatoes in individual ramekins for a charming, personal touch at dinner parties. Alternatively, layering them in a decorative gratin dish emphasizes the stunning golden baked topping and makes your table look extra inviting. Leftovers can be sliced like a casserole for easy reheating and elegant plating.
Make Ahead and Storage
Storing Leftovers
Place leftover Cheesy Scalloped Potatoes in an airtight container and store in the refrigerator for up to 3 days. The flavors often deepen overnight, making it even tastier the next day.
Freezing
This recipe freezes well when cooled completely. Wrap tightly and freeze for up to one month. Thaw overnight in the refrigerator before reheating to preserve the creamy texture.
Reheating
Reheat leftovers gently in an oven at 350°F covered with foil to prevent drying out. Alternatively, microwave individual portions until warmed through. If you like, broil for a minute to regain that delightful golden crust.
FAQs
Can I use other types of potatoes?
Absolutely! While russets are ideal for their starch content and tenderness, Yukon Golds or even red potatoes can work, just expect slight texture differences.
Is it possible to make this recipe vegetarian?
Yes, as long as you use vegetarian cheese (no animal rennet) and skip any meat additions, this recipe is naturally vegetarian-friendly and delicious.
What can I do if I don’t have mild cheddar?
You can substitute with other melty cheeses such as Colby, Monterey Jack, or even a sharper cheddar if you prefer a more intense flavor.
How thick should the potato slices be?
About ¼-inch slices are perfect—they cook evenly and soak up the cheese sauce without becoming mushy or underdone.
Can I add herbs or spices to the cheese sauce?
Definitely! A pinch of nutmeg, garlic powder, or fresh thyme can add wonderful subtle flavors without overpowering the cheesy richness.
