Ingredients
- 1 package (about 20 oz) frozen hash browns, thawed
- 8 large eggs
- 1 cup milk (dairy or plant-based)
- 1 cup shredded cheddar cheese
- 1/2 cup diced onion
- 1/2 cup diced bell pepper (optional)
- 1/2 cup cooked bacon or sausage (optional, for extra protein)
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Salt and pepper to taste
- 2 tablespoons melted butter (for greasing)
- Fresh parsley for garnish (optional)
Instructions
Step 1: Preheat the Oven and Prepare the Baking Dish
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with the melted butter to ensure the casserole doesn’t stick.
Step 2: Layer the Hash Browns
Spread the thawed hash browns evenly in the prepared baking dish, pressing them down slightly to form a base layer.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, beat the eggs with the milk until well combined. Add the garlic powder, onion powder, salt, and pepper. Stir in the shredded cheddar cheese, diced onion, bell pepper, and cooked bacon or sausage (if using). Mix everything together until evenly distributed.
Step 4: Assemble the Casserole
Pour the egg mixture evenly over the layer of hash browns in the baking dish. Use a spatula to gently spread the mixture and make sure the eggs cover all of the hash browns.
Step 5: Bake
Bake the casserole in the preheated oven for about 35-40 minutes, or until the eggs are set and the top is golden brown. You can check doneness by inserting a toothpick—if it comes out clean, the casserole is ready.
Step 6: Serve and Garnish
Remove from the oven and let the casserole rest for a few minutes before cutting. Garnish with fresh parsley if desired, and serve hot.
