• All-purpose flour - 2 tablespoons
• Whole milk - 2 cups
• Sharp cheddar cheese - 1 cup, shredded

How to Make Potato Recipes

Plan for 20 minutes of prep, 55 minutes of cooking, and 10 minutes of resting time before serving. That little rest helps the creamy sauce settle into the potatoes.

Step 1: Preheat the Oven

Preheat the oven to 375°F so it is ready when the casserole is assembled.

Step 2: Grease the Baking Dish

Grease a 9x13-inch baking dish with 1 tablespoon of butter. Coat the bottom and sides lightly so the casserole lifts out more easily.

Step 3: Melt the Butter

Melt the remaining butter in a medium saucepan over medium heat. Keep the heat moderate so the butter does not brown.

Step 4: Soften the Onion

Add the chopped onion and cook for 4 minutes, stirring occasionally, until softened and fragrant.

Step 5: Add the Flour

Whisk the flour into the onion mixture until it is well combined. This flour will help thicken the creamy sauce.

Step 6: Whisk in the Milk

Gradually whisk in the milk, adding it in a steady stream. Continue whisking until the mixture is smooth.

Step 7: Simmer the Sauce

Simmer the sauce for 5 minutes, stirring often, until it has thickened slightly. Do not let it boil hard.

Step 8: Season the Cheese Sauce

Stir the cheddar cheese, salt, black pepper, and garlic powder into the sauce. Continue stirring until the cheese melts into a smooth, savory mixture.

Step 9: Layer the Potatoes

Arrange the thinly sliced potatoes in the prepared baking dish. Spread them into an even layer so they cook consistently.

Step 10: Add the Cheese Sauce

Pour the cheese sauce evenly over the potatoes. Gently spread it if needed so the sauce reaches across the casserole.

Step 11: Add the Breadcrumbs

Sprinkle the breadcrumbs evenly over the top. They will bake into a lovely golden crust.

Step 12: Bake the Casserole

Bake the casserole for 55 minutes, until the potatoes are tender and the top is golden. Check the potatoes with a fork in the center of the dish.

Step 13: Let It Rest

Rest the casserole for 10 minutes before serving. This gives the sauce time to settle and makes each serving easier to scoop.

Step 14: Add the Parsley

Sprinkle the chopped parsley over the casserole just before serving. The fresh green color is a cheerful finishing touch.

Make Ahead and Storage

Storing Leftovers

FAQs

Here are a few helpful answers before you bring this cozy casserole to the table.

Can I use a different type of potato?

Yes. Yukon Gold potatoes are especially creamy, but russet or red potatoes can also work when sliced thinly and evenly.

Can I prepare this casserole ahead of time?

You can prepare the sauce and slice the potatoes shortly before baking. For the best texture, assemble and bake the casserole the same day.

How do I know when the potatoes are done?

Insert a fork into the center of the casserole. The potatoes are ready when the fork slides through the slices easily.

Why should the casserole rest before serving?

A 10-minute rest lets the cheese sauce settle into the potato layers, making the casserole easier to serve and enjoy.
