Hash Brown Breakfast Casserole Ingredients
- 1 package (30 ounces) frozen hash browns, thawed
- 8 large eggs
- 2 cups shredded cheddar cheese
- 1 pound breakfast sausage, cooked and crumbled
- 1 cup milk
- 1/2 cup diced onion
- 1/2 cup diced bell pepper
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 tablespoons butter, melted
How to Make Hash Brown Breakfast Casserole
Step 1: Prepare the Ingredients
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or butter. Cook the breakfast sausage in a skillet over medium heat until browned and fully cooked. Drain any excess grease and set the sausage aside. Make sure the hash browns are thawed so they mix evenly with the other ingredients.
Step 2: Create the Hash Brown Layer
In a large mixing bowl, combine the thawed hash browns, cooked sausage, diced onion, diced bell pepper, melted butter, and half of the shredded cheese. Stir everything together until the ingredients are evenly distributed. Spread the mixture evenly into the prepared baking dish, creating a solid base for the casserole.
Step 3: Prepare the Egg Mixture
In a separate bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper. Continue whisking until the mixture is smooth and fully combined. Slowly pour the egg mixture over the hash brown mixture, making sure it reaches all corners of the baking dish so every bite cooks evenly.
Step 4: Add Cheese and Bake
Sprinkle the remaining shredded cheese evenly over the top of the casserole. Place the baking dish in the preheated oven and bake for 40 to 50 minutes. The casserole is done when the center is set, the eggs are fully cooked, and the top is golden brown and bubbly.
Step 5: Cool and Serve
Remove the casserole from the oven and allow it to rest for about 10 minutes before slicing. This helps the casserole hold its shape and makes serving easier. Cut into squares and serve warm with your favorite breakfast sides.
