Ingredients You’ll Need

Simple ingredients come together beautifully in this recipe, each bringing its own magic to the dish. From the earthy potatoes to the rich cheeses and fragrant herbs, every element plays a role in creating layers of flavor and creamy, dreamy texture.

• Yukon Gold or Russet Potatoes: Choose starchy potatoes sliced thinly for even cooking and the perfect tender bite.
• Butter: Adds richness and helps caramelize the onions for that deep, sweet taste.
• Olive Oil: Balances butter and prevents burning during onion caramelization.
• Yellow Onion: Caramelized slowly for 30 minutes to build a sweet, savory flavor base.
• Dried Thyme: Adds an herbal note that complements the creamy sauce without overwhelming it.
• Garlic: Infuses the roux with warmth and depth in every spoonful.
• Flour: Creates the roux to thicken the sauce perfectly.
• Milk: Forms the velvety sauce base that coats each potato slice luxuriously.
• Shredded Orange Cheddar Cheese: Sharp and melty, it’s the star ingredient creating that irresistible cheesy pull.
• Cream Cheese: Adds extra creaminess and tang, elevating the sauce texture.
• Mustard Powder: A hint of sharpness that brightens the overall flavor profile.
• Salt and Pepper: Essential seasonings that bring out all the flavors beautifully.
• Cayenne Pepper: Just a pinch to add a subtle kick and balance the richness.

How to Make Cheesy Scalloped Potatoes Recipe

Step 1: Prepare Ingredients

Begin by preheating your oven to 350°F (175°C) and preparing all your ingredients. Peel and slice the potatoes into thin 1/8-inch rounds, mince the garlic, measure spices, and prepare your cheese. Getting everything ready ahead makes the cooking process smooth and enjoyable.

Step 2: Caramelize Onions

In a large skillet over medium-low heat, melt 2 tablespoons of butter with olive oil. Add thinly sliced yellow onions and dried thyme, cooking slowly for about 30 minutes until the onions turn golden brown and develop a sweet richness. This step adds incredible depth and a lovely sweetness to the final dish.

Step 3: Make Roux

Increase the heat to medium and melt the remaining 4 tablespoons of butter in the skillet. Add the minced garlic and cook for 1 minute, releasing fragrant aromas. Whisk in the flour continuously for about a minute to cook out the raw flour taste and form a smooth roux ready to thicken the sauce.

Step 4: Add Milk

Slowly pour in the milk, whisking constantly to avoid lumps, until a creamy sauce forms. Bring it to a gentle boil to activate the thickening before removing from heat.

Step 5: Season Sauce

Enhance the sauce by stirring in mustard powder, salt, pepper, and a pinch of cayenne pepper. These seasonings create complexity and balance that cuts through the creamy richness.

Step 6: Add Cheese & Cream Cheese

Allow the sauce to cool slightly, then gradually melt in most of the shredded cheddar cheese, reserving 1 cup for topping. Stir in softened cream cheese and the caramelized onions, combining everything into a silky, flavorful sauce.

Step 7: Slice Potatoes

If not done earlier, peel and rinse the potatoes now. Slice them thinly at about 1/8-inch thickness to ensure even cooking and to allow them to soak up the cheesy sauce.

Step 8: Layer Potatoes and Sauce

Grease a 9×13-inch baking dish. Lay half of the potato slices in an even layer, spoon half of the cheese sauce over them, then repeat with the remaining potatoes and sauce. Sprinkle the reserved cheddar cheese evenly on top to create a golden crust as it bakes.

Step 9: Bake

Cover the dish with foil and bake for 45 minutes. Remove the foil and continue baking for 40 more minutes until the potatoes are fork-tender and the top is bubbling and golden. This slow bake is crucial for the perfect tender texture and gooey cheesy finish.

Step 10: Broil and Rest

For an extra gorgeous browned top, broil the potatoes at 400°F for a few minutes, watching carefully to prevent burning. Let the casserole rest for 5 to 10 minutes before serving, allowing the sauce to settle and thicken slightly.

How to Serve Cheesy Scalloped Potatoes Recipe

Garnishes

Freshly chopped parsley or chives brighten the creamy potatoes with a pop of color and a subtle herbal note. You can also sprinkle a little extra sharp cheddar for visual appeal and a cheesy boost.

Side Dishes

This dish pairs wonderfully with roasted meats like chicken, beef, or ham. A crisp green salad or steamed veggies offer a refreshing counterbalance to the richness of the cheesy scalloped potatoes.

Creative Ways to Present

Consider serving the potatoes in individual ramekins for elegant personal portions at a dinner party. Alternatively, spoon the hot casserole into hollowed-out roasted bell peppers or sweet potatoes for a delightful twist.

Make Ahead and Storage

Storing Leftovers

Cover and refrigerate any leftover scalloped potatoes in an airtight container for up to 4 days. The flavors meld beautifully overnight, making leftovers even tastier.

Freezing

You can freeze the assembled but unbaked dish for up to 2 months. Thaw overnight in the refrigerator before baking as directed. Freezing after baking is possible but may slightly change the creamy texture.

Reheating

Reheat leftovers in a 350°F oven until warmed through to retain the crispy topping. Microwaving is an option for a quicker meal, though the top won’t stay as crisp.

FAQs

Can I use other types of potatoes for this recipe?

Absolutely! Yukon Gold and Russets are ideal because of their texture and starch content, but you can experiment with other varieties like red potatoes. Just keep in mind that waxy potatoes may not become as tender and creamy.

Is there a way to make this dish gluten-free?

Yes! Replace the all-purpose flour with a gluten-free flour blend or use cornstarch as a thickener. Ensure all other ingredients, like mustard powder, are certified gluten-free if dietary restrictions apply.

Can I add other cheeses?

Definitely. While sharp cheddar gives that classic flavor, mixing in Gruyere or mozzarella can add a lovely melt and nuance. Just keep the total cheese amount about the same for best results.

How thin should I slice the potatoes?

The potatoes should be sliced about 1/8-inch thick for even cooking and to perfectly absorb the sauce without falling apart. A mandoline slicer works wonders for uniform slices.

Can this recipe be made vegetarian?

This recipe is already vegetarian as written, assuming you use a cheese made without animal rennet. It pairs well with many vegetarian main dishes or can be enjoyed on its own as a hearty meal.
