Ingredients

Serves 6 generously

The Beef Layer

• 1 pound lean ground beef (85/15 or 90/10)
• 1 small yellow onion, finely diced
• 1 teaspoon garlic powder
• ½ teaspoon black pepper
• ½ teaspoon salt

The Creamy Casserole Base

• 1 bag (30 ounces) frozen diced or shredded hashbrowns
• 1 can (10.5 ounces) condensed cream of mushroom soup
• ½ cup whole milk or beef broth
• 2 cups sharp cheddar cheese, shredded and divided

Why Frozen Hashbrowns Work Best

Many people wonder why frozen hashbrowns are preferred over fresh potatoes in casseroles.

The answer lies in moisture control.

Fresh potatoes contain a large amount of water. During baking, they release this moisture, which can make casseroles watery and prevent proper thickening.

Frozen hashbrowns are partially cooked and slightly dehydrated before packaging. As they bake, they absorb the creamy sauce and beef juices instead of releasing excess liquid.

The result is a perfectly creamy casserole with no soggy center.

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.
