The combination of tender potatoes and a rich, flavorful sauce makes scalloped potatoes a dish that never goes out of style.
Preheat and Prepare
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with butter or nonstick spray. This will prevent the potatoes from sticking and make cleanup easier.
Prepare the Creamy Cheese Sauce
In a medium saucepan over medium heat, melt the butter. Add the flour and whisk constantly for 1–2 minutes to form a roux. This cooks out the raw flour taste and will thicken the sauce.
Gradually whisk in the warm milk, making sure to eliminate any lumps. Continue to cook until the sauce begins to thicken, about 5–7 minutes.
Remove from heat and stir in ¾ cup of cheddar cheese, garlic, salt, and pepper until melted and smooth.
The cheese sauce should be creamy, slightly thick, and full of flavor—it will coat the potatoes beautifully.
Slice the Potatoes
Peel the potatoes and slice them into ¼-inch thick rounds. Use a sharp knife or mandoline for even slices, which ensures uniform cooking.
Even slices allow the potatoes to cook at the same rate and create an attractive layered presentation.
Layer the Potatoes
Arrange a layer of potato slices in the bottom of the prepared baking dish. Pour a portion of the cheese sauce over the layer, spreading it evenly.
Repeat the layers, alternating potatoes and sauce, until all potatoes and sauce are used. Sprinkle the remaining cheddar and Parmesan on top for a golden, cheesy crust.
Optional: Sprinkle paprika or dried thyme over the top for color and added flavor.
Cover and Bake
Cover the baking dish tightly with aluminum foil to prevent the top from browning too quickly while the potatoes cook through.
Bake in the preheated oven for 45 minutes.
Uncover and Finish Baking
Remove the foil and bake for an additional 20–25 minutes, or until the potatoes are tender and the top is golden brown and bubbling.
Check for doneness by inserting a knife into the center—potatoes should slide easily without resistance.
Rest Before Serving
Let the scalloped potatoes rest for 5–10 minutes before serving.
Resting allows the sauce to thicken slightly, making the dish easier to serve and giving the flavors time to meld together.
Flavor and Texture Highlights
- Tender potato slices cooked to perfection
- Creamy, cheesy sauce with rich flavor
- Golden, bubbly top with slightly crisp edges
- Subtle garlic and spice notes enhance the richness
Every bite offers a balance of soft potatoes and rich, savory sauce, with just the right amount of cheese pull.
Tips for Perfect Scalloped Potatoes
- Use starchy potatoes like Russet for fluffier layers or Yukon Gold for a creamier texture.
- Slice potatoes evenly to ensure uniform cooking.
- Warm the milk before adding to the roux to prevent lumps.
- Cover during the initial bake to prevent the top from burning.
- Let the dish rest before serving to thicken the sauce.
Optional Variations
- Bacon and Onion: Add cooked bacon bits and sautéed onions between layers.
- Herb-Infused: Mix fresh rosemary, thyme, or sage into the cheese sauce.
- Extra Cheesy: Use a blend of cheeses like Gruyère, Fontina, or mozzarella for depth of flavor.
- Spicy Kick: Add a pinch of cayenne or red pepper flakes to the cheese sauce.
- Vegetable Boost: Layer in thin slices of zucchini, sweet potato, or cauliflower for variety.
Storage and Serving
- Serve immediately for the best texture.
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat covered in the oven at 350°F (175°C) until warmed through.
- Can be prepared ahead and baked just before serving—cover and refrigerate overnight.
