Key Ingredients
To make these Creamy Cheesy Oven-Baked Scalloped Potatoes, you’ll need a handful of simple pantry staples that transform into something extraordinary once baked.

- 1 medium onion thinly sliced: Adds sweet, aromatic pockets of flavor between the potato layers.
- 2 tablespoons butter: Forms the flavorful fat base for the roux that thickens your sauce.
- 2 tablespoons all-purpose flour: Combines with butter to create a smooth roux for a silky cheese sauce.
- 1 1/2 cups whole milk: Provides creaminess and body to the sauce’s smooth texture.
- 1 cup heavy cream: Boosts richness and gives each bite a luscious mouthfeel.
- 1 teaspoon salt: Enhances all the flavors and balances the richness of the cheese.
- 1/2 teaspoon black pepper: Delivers a gentle kick and depth to the creamy sauce.
- 1/2 teaspoon garlic powder: Infuses a mellow garlic undertone without overpowering the dish.
- 1 cup shredded cheddar cheese: Melts into rich, sharp pockets of flavor throughout.

- 1 tablespoon fresh parsley chopped: Offers a fresh, herby finish and a pop of color.
How To Make Creamy Cheesy Oven-Baked Scalloped Potatoes
Let’s walk through the steps to build these irresistible layers of potatoes, onions, and creamy cheese sauce before they head into the oven. You’ll start by creating a classic roux, then whisk in milk and cream for a velvety sauce, layer everything up, and bake until golden and bubbling.
1. Preheat the oven to 375°F and generously butter a 9×13-inch baking dish to prevent sticking and promote a crisp edge.
2. In a medium saucepan, melt the butter over medium heat until it’s fully liquid and beginning to foam.
3. Add the flour, stirring constantly with a whisk for about 1 minute until it forms a smooth, pale golden roux.
4. Gradually pour in the milk and cream, whisking constantly to prevent lumps, then bring the mixture to a gentle simmer.
5. Season with salt, black pepper, and garlic powder, and let the sauce simmer for 5 minutes until it thickens enough to coat the back of a spoon.
6. Remove the saucepan from heat and stir in the cheddar cheese and half of the Parmesan, whisking until fully melted and smooth.
7. Arrange half of the potatoes and onions in an even layer in the prepared dish, then pour half of the cheese sauce over the top.
8. Repeat with the remaining potatoes, onions, and sauce, then sprinkle the rest of the Parmesan cheese evenly over the surface.
9. Cover the dish with foil and bake for 45 minutes, then remove the foil and bake for an additional 15 minutes until the top is golden brown and bubbling.
10. Let the scalloped potatoes rest for 10 minutes before serving, then garnish with the chopped parsley for a fresh finish.
Serving Suggestions
These scalloped potatoes shine as a hearty side or even a vegetarian main—here’s how to serve them with flair and balance.
- Crisp green salad: A mix of arugula and baby spinach tossed in a tangy lemon vinaigrette cuts through the richness.
- Garlic-roasted veggies: Roast broccoli or Brussels sprouts with a touch of olive oil and minced garlic for an earthy complement.
- Herb-roasted chicken: Juicy chicken thighs or breasts seasoned with rosemary and thyme pair beautifully with the cheesy layers.
- Chilled white wine: A glass of Chardonnay or Sauvignon Blanc adds bright acidity that balances every creamy bite.

Frequently Asked Questions
Here are quick answers to common questions—everything you need to know for flawless scalloped potatoes!
- How long does it take to prepare and bake the creamy cheesy oven-baked scalloped potatoes?
It takes about 20 minutes to prepare—this covers slicing 2 pounds of potatoes and one onion, measuring ingredients, and preheating the oven to 375°F. Baking requires 45 minutes covered with foil plus 15 minutes uncovered, and a 10-minute resting period. In total, plan for roughly 1 hour and 30 minutes from start to finish.
- What type of potato is best for this recipe, and how thin should I slice them?
Starchy potatoes like russets or all-purpose varieties such as Yukon Gold work well. Aim for uniform slices about 1/8-inch thick so they cook evenly and become tender without turning mushy. A mandoline slicer ensures consistent thickness and speeds up prep.
- Can I substitute or add different cheeses to change the flavor profile?
Yes. While the recipe calls for 1 cup shredded cheddar and ½ cup grated Parmesan, you can swap cheddar for Gruyère or Fontina to add nuttiness and depth. If you prefer a sharper tang, use extra-sharp cheddar. Just keep the total cheese volume the same to maintain sauce consistency.
- How should I store and reheat leftovers to retain creaminess?
After baking, let the scalloped potatoes cool to room temperature, then cover tightly and refrigerate for up to 3 days. To reheat, place portions in an oven-safe dish, cover with foil, and bake at 350°F for 15–20 minutes until warmed through. Uncover for the last 5 minutes to refresh the golden top. Alternatively, microwave individual servings on medium power for 2–3 minutes, stirring halfway through.
- Can I make this dish ahead of time and freeze it?
Yes. Assemble the layers and cheese sauce as directed, then cover the dish tightly with foil and a layer of plastic wrap. Freeze for up to one month. When ready to bake, thaw overnight in the refrigerator, remove plastic wrap, and bake at 375°F for 45 minutes covered, then 15 minutes uncovered, finishing with a 10-minute resting period.
- How can I adapt the recipe for gluten-free diets?
Replace the 2 tablespoons of all-purpose flour with a gluten-free flour blend or cornstarch. If using cornstarch, mix 1 tablespoon with a tablespoon of cold milk before whisking into the sauce to prevent lumps. Proceed with the recipe as written to achieve a thick, creamy sauce.
- Why is it recommended to rest the scalloped potatoes for 10 minutes before serving?
Resting allows the sauce to cool slightly and thicken, helping the layers set and making it easier to slice neat portions. It also firms up the cream and cheese mixture, ensuring each serving holds together beautifully without running liquid on the plate.
