This recipe uses simple, widely loved ingredients that come together to create a dish that’s rich in flavor and texture. Each component plays a crucial role, from the cream of chicken soup adding creaminess to the sharp cheddar creating that irresistible cheesy crust.

Frozen Hash Browns (32 oz): The base of the dish, bringing hearty substance and a tender potato texture once baked.
Sour Cream (2 cups): Adds tanginess and creaminess that binds everything beautifully.
Onion (1 small, finely chopped): Offers a subtle savory sweetness that brightens the casserole.
Cream of Chicken Soup (1 can): Provides a rich, comforting flavor and creamy consistency essential for the casserole’s texture.
Shredded Cheddar Cheese (2 cups, divided): Adds sharpness and melty goodness, with some mixed in and some sprinkled on top for a golden finish.
Butter (1/4 cup, melted): Boosts richness and helps everything meld together perfectly.
Salt (1 teaspoon): Enhances all the flavors without overpowering the dish.
Black Pepper (1/4 teaspoon): Adds the slightest kick and complements the mellow ingredients.

How to Make Cheesy Hashbrown Potato Casserole Recipe

Step 1: Preheat and Prepare the Pan

Begin by heating your oven to 350°F while lightly greasing a 13×9 inch baking dish. This step ensures the casserole won’t stick and will come out perfectly golden without any fuss.

Step 2: Combine Your Ingredients

Grab a large mixing bowl and toss together the thawed hash browns, sour cream, finely chopped onion, cream of chicken soup, 1 ½ cups of shredded cheddar cheese, melted butter, salt, and black pepper. This mixture should be creamy and well blended, with each ingredient evenly distributed to guarantee every bite bursts with flavor.

Step 3: Adjust Seasonings and Transfer

Give your mixture a taste and see if it needs a pinch more salt or pepper to suit your palate. Once happy, spread it evenly into the prepared baking dish. This even layer is key for consistent cooking and a lovely crispy top later.

Step 4: Bake to Perfection

Place the casserole uncovered in the oven and bake for 45 minutes at 350°F. This phase allows the casserole to come together, the flavors to meld, and the potatoes to cook through.

Step 5: Add Final Cheese Layer and Finish Baking

After the initial bake, remove the casserole and sprinkle the remaining ½ cup of shredded cheddar cheese evenly on top. Return the dish to the oven and bake for another 10 minutes or until the cheese is melted, golden, and bubbling delightfully.

Garnishes

A little flourish goes a long way with this casserole. Fresh chopped chives or green onions bring a pop of color and a mild onion crispness that cuts through the rich cheesy layers beautifully. You can also add crispy bacon bits for an irresistible smoky crunch if you like.

Side Dishes

This casserole pairs wonderfully with light and fresh sides such as a crisp green salad with a lemon vinaigrette or steamed seasonal vegetables. Its richness harmonizes well with simple, clean flavors that balance out the heaviness.

Creative Ways to Present

Try serving individual portions in small ramekins for a charming presentation perfect for dinner parties. Or sprinkle a little extra cheese and breadcrumbs on top before the final bake to create an even crispier crust. For a brunch twist, top it with a fried egg and some avocado slices.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers from this Cheesy Hashbrown Potato Casserole Recipe, simply cover the dish tightly with foil or transfer portions to airtight containers. Refrigerate and enjoy within 3 to 4 days for the best flavor and texture.

Freezing

This casserole freezes beautifully. Prepare the dish as directed but hold off on the final cheese topping. Wrap it tightly with plastic wrap and foil, then freeze for up to 3 months. When ready to enjoy, bake covered at 350°F until heated through, then add the cheese topping and bake until bubbly.

Reheating

Reheat leftovers in the oven at 350°F until warmed through and the cheese is bubbly again—usually about 20 to 25 minutes. Microwaving works in a pinch but may soften the crispy top.

FAQs

Can I use fresh potatoes instead of frozen hash browns?

While fresh potatoes can work, using frozen hash browns is convenient and ensures consistent texture. If using fresh, grate them finely and make sure to squeeze out excess moisture to avoid a soggy casserole.

Is there a vegetarian alternative for cream of chicken soup?

Absolutely! You can substitute cream of mushroom or cream of celery soup to keep it vegetarian without sacrificing creaminess and flavor.

Can I make this casserole dairy-free?

Yes, use dairy-free sour cream, butter substitutes, and plant-based cheese alternatives to adapt this recipe. The texture might vary slightly, but it will still be deliciously comforting.

How can I make this casserole spicier?

Add a pinch of cayenne pepper or a few dashes of hot sauce mixed in before baking. For a touch of smoky heat, smoked paprika works wonderfully as well.

Will this casserole work as a main dish?

Definitely! Adding cooked diced chicken, sausage, or extra vegetables can turn this side dish into a satisfying main meal perfect for any time of day.
