Notes
A Homemade Cheese Sauce
The heart of Cheesy Hashbrown Casserole is the creamy cheese sauce. Cooking onions and garlic in olive oil builds a savory base. Flour thickens the sauce, while milk and chicken stock add richness and depth.
Sharp Cheddar cheese provides bold flavor, while sour cream adds tang and creaminess. Fresh parsley brings a touch of brightness that keeps the dish from feeling too heavy.
How to Make Cheesy Hashbrown Casserole Step by Step
Building the Flavor Base
Start by sautéing diced onion in olive oil until soft and lightly golden. This step adds sweetness and depth to the casserole. Garlic follows briefly, releasing aroma without browning.
Sprinkling flour over the onion and garlic creates a roux, which thickens the sauce. Stirring well ensures the flour coats everything evenly.
Creating a Smooth, Creamy Sauce
Gradually adding chicken stock while stirring helps prevent lumps. Milk follows slowly, creating a smooth, velvety sauce as it heats. Cooking the mixture until thickened is key for a casserole that holds together well.
Once off the heat, sour cream and shredded Cheddar cheese melt into the sauce, creating a rich and creamy texture. Seasoning with salt and black pepper ensures balanced flavor throughout.
Assembling and Baking
The thawed hash browns are mixed thoroughly with the cheese sauce so every strand is coated. Spreading the mixture evenly into a baking dish ensures consistent baking.
A final layer of shredded Cheddar cheese melts on top, forming a golden, bubbly crust as it bakes. The result is a casserole that looks as good as it tastes.
Best Ways to Serve Cheesy Hashbrown Casserole
Breakfast and Brunch Pairings
Cheesy Hashbrown Casserole is a standout on any breakfast or brunch table. It pairs perfectly with scrambled eggs, omelets, or breakfast meats. Adding fresh fruit or a simple salad on the side balances the richness.
Because it stays warm and holds its texture, it is ideal for serving a crowd.
As a Hearty Side Dish
At dinner, Cheesy Hashbrown Casserole works beautifully alongside roasted chicken, pork, or beef. It also complements vegetable-based mains, adding heartiness to lighter plates.
Leftovers reheat well, making it practical for meal prep or next-day lunches.
Tips for the Best Cheesy Hashbrown Casserole
Thaw and Drain the Hash Browns
Fully thawing the hash browns is essential. Excess moisture can make the casserole watery. If needed, gently squeeze out extra liquid before mixing them with the sauce.
This step helps ensure a creamy, cohesive texture.
Use Sharp Cheese for Flavor
Sharp Cheddar adds boldness that stands up to the potatoes and cream. Milder cheeses can work, but the flavor will be less pronounced.
Shredding the cheese yourself rather than using pre-shredded versions helps it melt more smoothly.
Easy Variations to Try
Extra Crunchy Topping
For added texture, sprinkle breadcrumbs or crushed crackers over the cheese topping before baking. This creates a crisp contrast to the creamy interior.
Add-Ins for More Flavor
Cooked bacon, ham, or sausage can be mixed into the casserole for a heartier version. Diced bell peppers or green onions add color and freshness.
These variations allow you to customize Cheesy Hashbrown Casserole without changing the base recipe.
