Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
A properly heated oven is essential for creating the crispy, golden edges that make this casserole so irresistible.
Step 2: Brown the Ground Beef
Place a large skillet over medium-high heat.
Add the ground beef and diced onion.
Cook for 6 to 8 minutes, stirring occasionally, until:
- The beef is fully browned.
- The onions become soft and translucent.
Drain any excess grease.
Stir in the garlic powder, salt, and black pepper.
Remove from heat.
Step 3: Create the Creamy Sauce
In a large mixing bowl, combine:
- Cream of mushroom soup
- Milk or beef broth
Mix until smooth.
Add 1½ cups of the shredded cheddar cheese and stir well.
The cheese begins creating the rich, creamy texture that makes this casserole so satisfying.
Step 4: Fold Everything Together
Add the frozen hashbrowns directly from the freezer.
Add the cooked ground beef mixture.
Gently fold everything together until evenly coated.
At this stage, the mixture may seem somewhat thick. This is normal. The potatoes will release just enough moisture during baking to create the perfect consistency.
Step 5: Transfer to Baking Dish
Spread the mixture evenly into the prepared baking dish.
Use a spatula to smooth the top.
This helps ensure even cooking and creates a beautiful finished appearance.
Step 6: First Bake
Bake uncovered for 35 minutes.
During this time, the flavors begin to meld together while the potatoes absorb the creamy sauce.
