Ingredients You’ll Need

There are around three stacks, each with light yellow potato slices and white onion slices layered evenly from one side to the other. The layered slices are sprinkled with black pepper, adding specks across the smooth surfaces. The background shows a white marbled table, and a light beige napkin is partly visible under the dish.

The beauty of this Easy and Delicious Cheesy Scalloped Potatoes Recipe is in its simplicity. Each ingredient plays an essential role, whether it’s providing creamy texture, savory flavor, or a beautiful golden color that makes the dish irresistible. Here’s what you’ll need to gather:

Russet potatoes: I like using about 2 pounds of peeled and thinly sliced potatoes for creaminess and that perfect tender bite.
Yellow onion: Sliced into rings, it adds a subtle sweetness that complements the cheese beautifully.
Unsalted butter: Essential for the roux, it gives the sauce a rich base without overpowering saltiness.
All-purpose flour: Helps to thicken the cheese sauce into the wonderfully creamy consistency I love.
Kosher salt: For seasoning the sauce and highlighting the natural flavors of the potatoes and cheese.
Whole milk: I use room temperature milk to ensure the sauce blends smoothly and thickens nicely.
Mild cheddar cheese: Shredded, it melts perfectly into the sauce, providing that classic cheesy flavor.
Salt and pepper: To taste, for that final touch of seasoning that brings everything together.

Directions

Step 1: Preheat your oven to 400°F (204°C). Lightly spray an 8×8-inch casserole dish with nonstick cooking spray to prevent sticking and make cleanup easier.

Step 2: Peel your russet potatoes and slice them into uniform ¼-inch thick rounds. Slice the yellow onion into rings. Arrange the potatoes and onions in the prepared dish by staggering slices of potato and rings of onion to create layers.

Step 3: To make the cheese sauce, melt three tablespoons of unsalted butter in a medium saucepan over medium heat. Once melted, whisk in three tablespoons of all-purpose flour and ½ teaspoon kosher salt. Keep whisking constantly for about one minute to cook off the raw flour taste and form a smooth roux.

Step 4: Slowly whisk in two cups of whole milk (at room temperature) and continue to cook, stirring frequently, until the sauce thickens to a creamy consistency—this usually takes a few minutes.

Step 5: Once thickened, remove the sauce from heat and immediately stir in 1 ½ cups of shredded mild cheddar cheese. Mix continuously until the cheese melts fully and the sauce is silky smooth, about 30 to 60 seconds.

Step 6: Pour the cheese sauce evenly over the potatoes and onions in the casserole dish, making sure every slice is coated.

Step 7: Cover the dish tightly with aluminum foil and bake in the preheated oven for 85 to 90 minutes. The potatoes should become tender when pierced with a fork.

Step 8: For a crisp, golden top, remove the foil and switch your oven to the broil setting. Broil the scalloped potatoes for a few minutes, watching carefully until the top is bubbly and browned to your liking.

Step 9: Remove from the oven, season with additional salt and freshly ground pepper to taste, and serve immediately while warm and comforting.

Servings and Timing

This Easy and Delicious Cheesy Scalloped Potatoes Recipe yields about 8 generous servings — perfect for a family dinner or bringing to a gathering. The prep time clocks in around 15 minutes since the slicing is simple and straightforward, while the active cooking time on the stove for the sauce takes about 10 minutes. The baking time is roughly 1 hour and 30 minutes to 1 hour and 35 minutes, which allows the dish to cook through and develop that tender texture and rich flavor. Altogether you want to set aside approximately 1 hour and 45 minutes from start to finish, including the broil step for that irresistible golden crust.

When I serve these cheesy scalloped potatoes, I like to pair them with something that contrasts their creamy, rich texture. Roasted or grilled meats, like herb-roasted chicken, tender pork chops, or even a juicy steak, make fantastic companions. For a vegetarian meal, a crisp green salad with a tangy vinaigrette refreshes the palate beautifully.

Presentation-wise, I love garnishing with freshly chopped parsley or chives to add a pop of bright color and a fresh note to balance the richness. Using a white or neutral-toned dish really helps showcase the golden top layers, and serving in moderately sized portions — about one heaping scoop per person — ensures everyone gets enough cheesy goodness without feeling overwhelmed.

Beverage-wise, this dish pairs great with a chilled glass of lightly oaked Chardonnay, which enhances the creamy cheese flavors without overpowering them. For non-alcoholic options, a sparkling lemonade or herbal iced tea complements the textures and freshness wonderfully. This makes the recipe a hit whether at a relaxed weeknight meal, a cozy holiday gathering, or a celebratory potluck.

Variations

I love to experiment with this Easy and Delicious Cheesy Scalloped Potatoes Recipe to keep it fresh and cater to different preferences. For instance, swapping out the mild cheddar for a sharper sharp cheddar, Gruyère, or a blend adds deeper complexity to the sauce. You can also add garlic powder or fresh garlic to the butter for a flavor boost that lingers delightfully.

If you’re looking to make a gluten-free version, I suggest substituting the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. For those following a vegan lifestyle, I’ve tried using plant-based milk such as oat or almond milk combined with vegan butter and a store-bought vegan cheese sauce or nutritional yeast for that cheesy flavor. Just keep in mind the texture and flavor will adapt accordingly.

Another fun variation is adding sautéed mushrooms or spinach between the potato layers for a touch of earthiness and color. I sometimes prepare this dish in a larger casserole dish for holiday gatherings or make muffin-sized scalloped potato cups for individual servings when entertaining.

Storage and Reheating

Storing Leftovers

If you have leftovers, I always recommend storing them in an airtight container to keep moisture from making the dish soggy. Using a glass or BPA-free plastic container with a tight-fitting lid works best. When refrigerated, these scalloped potatoes remain delicious for up to 3 to 4 days. I usually portion them out to avoid reheating the entire batch multiple times.

Freezing

This dish freezes surprisingly well, which makes it ideal for meal prep. Before freezing, allow the scalloped potatoes to cool completely, then transfer them to a freezer-safe container or wrap tightly with plastic wrap and foil to avoid freezer burn. They’ll keep well frozen for about 2 months. When you’re ready to enjoy them again, thaw overnight in the refrigerator for best results before reheating.

Reheating

To reheat, I prefer using the oven to keep the texture crisp and creamy. Preheat it to 350°F (175°C), cover the dish loosely with foil to prevent drying out, and warm for about 20 to 30 minutes until heated through. Avoid microwaving if possible, as it can make the potatoes watery or unevenly heated. If you want to refresh the crispy top, remove the foil during the last 5 minutes of reheating and broil briefly but watch carefully to prevent burning.

FAQs

Can I prepare the scalloped potatoes ahead of time?

Absolutely! You can assemble the dish a day ahead, cover it tightly, and refrigerate. When ready to bake, simply add a few extra minutes to the baking time since it will be chilled. This makes it perfect for planning holiday meals or busy weeknights.

What type of potatoes work best for scalloped potatoes?

Russet potatoes are my go-to for this recipe because they have a high starch content that helps the slices become tender and absorb the creamy sauce. Yukon Gold potatoes also work well if you prefer a slightly waxier texture and a buttery flavor.

Is it necessary to use whole milk for the cheese sauce?

Whole milk gives the sauce its luscious creaminess, but you can substitute with 2% milk if needed. Just be aware the sauce might be a bit less rich and velvety. Avoid skim or non-dairy milks unless you’re adapting the recipe specifically, as these can affect texture.

How can I make this dish less heavy but still tasty?

To lighten it up, try using half the amount of cheese or substituting half of the milk with low-fat milk or broth. Adding some sliced vegetables like zucchini or cauliflower in layers helps add bulk with fewer calories while keeping things flavorful.

Can scalloped potatoes be made dairy-free or vegan?

Yes! Use plant-based milk such as almond or oat, dairy-free butter, and a vegan cheese alternative or nutritional yeast to replicate the cheesy flavor. The texture will change slightly, but the result can still be delicious and comforting.
