Ingredients You’ll Need

Gathering simple, wholesome ingredients is key to capturing the classic flavors and luscious texture of this dish. Each ingredient plays a distinct role, whether it’s the creamy dairy that creates richness or the sharp cheddar that brings a delightful tang and color.

• 3 pounds russet potatoes: The perfect starchy potato that holds its shape and melts in your mouth when sliced thinly.
• 4 tablespoons unsalted butter: Adds richness and a silky base for the sauce.
• 1 yellow onion, finely diced: Brings a sweet, aromatic depth as it softens gently in butter.
• 2 cloves garlic, minced: Infuses a subtle savory punch that brightens the overall flavor.
• 1/4 cup all-purpose flour: The thickening agent that transforms milk and cream into a velvety sauce.
• 2 cups whole milk: Provides creaminess and moisture that cooks the potatoes tenderly.
• 1 cup heavy cream: Elevates the sauce with luscious texture and richness.
• 2 cups sharp cheddar cheese, shredded: Adds a tangy, melty layer that’s truly the heart of scalloped potatoes.
• 1 1/2 teaspoons salt: Enhances every flavor, ensuring balance.
• 1/2 teaspoon black pepper: A gentle spice that rounds out the taste perfectly.
• Fresh thyme (optional): For an herbal twist that adds freshness and complexity.

How to Make Best Homemade Scalloped Potatoes Recipe

Step 1: Prepare the Oven and Baking Dish

Start by preheating your oven to 375°F and greasing a 9×13-inch baking dish. This ensures your scalloped potatoes bake evenly and don’t stick, allowing you to effortlessly serve perfect portions later.

Step 2: Sauté Onions in Butter

Melt 4 tablespoons of unsalted butter over medium heat in a saucepan. Add the finely diced yellow onion and sauté gently for about 5 minutes until the onions become soft and fragrant. This step unlocks sweet, mellow flavors that form the foundation for your creamy sauce.

Step 3: Add Garlic and Stir

Next, toss in the minced garlic and stir for about 30 seconds. Garlic should be fragrant but not browned, adding a savory brightness without overpowering the dish.

Step 4: Make the Roux

Sprinkle 1/4 cup all-purpose flour over the butter, onion, and garlic mixture. Whisk continuously to combine, creating a smooth roux. This crucial step thickens the sauce and helps it cling to every potato slice.

Step 5: Incorporate Milk and Cream

Gradually pour in 2 cups whole milk and 1 cup heavy cream while whisking vigorously. Continue to simmer the sauce for 5 to 7 minutes, stirring often until it thickens into a luscious, velvety consistency that coats a spoon beautifully.

Step 6: Melt in the Cheese and Season

Stir in 2 cups of shredded sharp cheddar cheese until fully melted into the sauce for that signature cheesy richness. Season with 1 1/2 teaspoons salt and 1/2 teaspoon black pepper, tasting as you go to achieve the perfect balance.

Step 7: Slice the Potatoes

Peel the russet potatoes and slice them thinly — about 1/8-inch thick is ideal. Thin slices cook evenly and absorb the sauce deeply, creating that melt-in-your-mouth texture everyone loves in scalloped potatoes.

Step 8: Layer the Potatoes and Sauce

Start by layering half of the potato slices in the greased baking dish, then pour half of the cheesy sauce over them. Repeat with the remaining potatoes and sauce for two beautiful, uniform layers ready to bake.

Step 9: Bake Covered

Cover the dish tightly with foil and bake at 375°F for 45 minutes. This protected cooking time allows the potatoes to soften and the flavors to meld without drying out.

Step 10: Bake Uncovered for Golden Finish

Remove the foil and bake for an additional 25 to 30 minutes. This step brings out that irresistible golden crust on top and ensures the potatoes are cooked through and tender all the way to the center.

Step 11: Rest Before Serving

Once out of the oven, let your scalloped potatoes rest for 10 minutes. This allows the sauce to thicken slightly and makes serving neat slices much easier.

Garnishes

A sprinkle of fresh thyme leaves or a pinch of chopped parsley adds a lovely burst of color and a hint of herbal brightness to your scalloped potatoes. It’s a simple touch that takes the presentation from comforting to elegant.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Your leftover scalloped potatoes will keep well in the refrigerator for up to 3 to 4 days. Simply cover tightly with plastic wrap or transfer to an airtight container to maintain freshness.

Freezing

While scalloped potatoes can be frozen, it’s best to freeze before baking to preserve the best texture. Assemble in a freezer-safe dish, cover tightly, and freeze for up to 2 months. When ready to eat, thaw overnight and bake as directed.

Reheating

Reheat leftovers gently in the oven at 350°F for about 20 minutes until warmed through. Cover loosely with foil to prevent drying, ensuring you’ll enjoy the same creamy, cheesy goodness as the first serving.

FAQs

Can I use a different type of potato for this recipe?

Russet potatoes are ideal because of their starchy texture that absorbs the sauce beautifully, but Yukon Gold potatoes can also work well for a creamier texture. Just be sure to slice them thinly for even cooking.

Is it possible to make this recipe dairy-free?

Yes! You can substitute dairy milk and cream with almond or oat milk, and use vegan butter and cheese alternatives. Just note that the texture and flavor will vary slightly but should remain delicious.

How can I make scalloped potatoes less rich?

To lighten the dish, reduce the amount of heavy cream or replace it with additional milk. Lower-fat cheeses or smaller cheese quantities will also help keep it less rich while still tasty.

Can I prepare this recipe ahead of time and bake later?

Absolutely! Assemble the scalloped potatoes, cover with foil, and refrigerate for up to 24 hours before baking. Baking time might need a few extra minutes if baking straight from the fridge.

What causes scalloped potatoes to be watery or runny?

This usually happens if potatoes aren’t sliced evenly or the sauce isn’t thick enough. Make sure your sauce is sufficiently thick before layering, and slice the potatoes uniformly to achieve the perfect consistency.
