Let’s dive into the recipe and explore the steps, tips, and tricks to create the ultimate hashbrown casserole.
Hashbrown Casserole: Ingredients
For the Casserole:
- 1 package (30 oz) of frozen hashbrowns (or about 6 cups fresh grated potatoes)
- 1 cup sharp cheddar cheese (shredded, plus extra for topping)
- 1 cup mozzarella cheese (shredded)
- 1/2 cup finely chopped onion (optional, but adds flavor depth)
- 1/2 cup melted butter
- 1 can (10.5 oz) cream of chicken soup (or use cream of mushroom for a vegetarian version)
- 1/2 cup sour cream
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
For the From-Scratch Béchamel Sauce:
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups whole milk (or half-and-half for extra creaminess)
- 1/2 cup sharp cheddar cheese (shredded, for extra creaminess)
- 1/2 teaspoon garlic powder (optional, for garlic flavor)
Instructions:
Step 1: Prepare the Béchamel Sauce
The foundation of this casserole’s indulgent richness lies in the from-scratch béchamel sauce. This sauce adds a creamy, velvety texture that elevates the dish from basic to spectacular.
- Melt the butter: In a medium saucepan, melt the 2 tablespoons of butter over medium heat.
- Make a roux: Once the butter is melted, whisk in the 2 tablespoons of flour. Continue to cook, whisking constantly, for about 1-2 minutes to eliminate the raw taste of the flour. This is your roux, which will thicken the sauce.
- Add the milk: Gradually whisk in the 1 1/2 cups of whole milk, making sure there are no lumps. Stir constantly as the sauce thickens. Bring it to a gentle simmer, cooking for about 3-5 minutes, until the sauce has thickened to a custard-like consistency.
- Incorporate the cheese: Stir in the 1/2 cup of sharp cheddar cheese until it melts into the sauce, making it wonderfully creamy. If you want a little extra flavor, add a pinch of garlic powder to the béchamel. Remove the saucepan from the heat and set it aside.
Step 2: Mix the Casserole Ingredients
While the béchamel sauce is thickening, it’s time to prep the other ingredients for the casserole.
- Preheat the oven: Preheat your oven to 350°F (175°C).
- Combine the casserole base: In a large mixing bowl, combine the frozen hashbrowns, 1 cup of shredded cheddar cheese, 1/2 cup of sour cream, 1/2 cup of melted butter, 1 can of cream of chicken soup, and the 1/2 cup of finely chopped onion (if using). Stir everything together until it’s well combined.
- Season the mixture: Add the garlic powder, onion powder, salt, and pepper to the mixture. Stir until the seasonings are evenly distributed throughout.
Step 3: Combine the Béchamel Sauce with the Hashbrown Mixture
- Pour in the béchamel: Once your béchamel sauce is ready, pour it over the hashbrown mixture. Stir well to ensure everything is evenly coated with that creamy sauce.
- Transfer to a baking dish: Lightly grease a 9×13-inch baking dish (or similar size) with butter or cooking spray. Transfer the hashbrown mixture into the dish, spreading it out into an even layer.
- Top with extra cheese: For that irresistible cheesy top, sprinkle some extra cheddar cheese and mozzarella cheeseover the top of the casserole.
Step 4: Bake to Perfection
- Bake the casserole: Place the casserole in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and bubbly. If you like an extra crispy top, turn the broiler on for the last 2-3 minutes, but be careful not to burn the cheese.
- Rest before serving: Once the casserole is done, remove it from the oven and let it rest for about 5-10 minutesbefore serving. This helps it firm up a bit so you can slice it into neat squares.
Why This Hashbrown Casserole Is So Special
1. From-Scratch Béchamel Sauce
The from-scratch béchamel is the true game-changer in this recipe. While many hashbrown casserole recipes rely on canned soups or processed cheese, the béchamel provides a silky, rich base that adds depth of flavor. It’s creamy without being too heavy, and the extra layer of sharp cheddar in the sauce adds complexity.
2. Perfectly Crispy Top
Baking the casserole gives it that golden, crispy top that everyone loves. It’s the best part of any casserole—a satisfying crunch that contrasts beautifully with the creamy, tender potatoes underneath. It’s what takes the casserole from comfort food to comfort-food excellence.

Tips for Perfecting Your Hashbrown Casserole
- Use Frozen Hashbrowns: Frozen hashbrowns make this recipe super easy and convenient. If you use fresh potatoes, be sure to grate them finely and cook them a bit beforehand to soften them up.

- Top It Off: After baking, you can top the casserole with a handful of chopped green onions or crispy fried onionsfor an extra layer of flavor and crunch.
