Ingredients You’ll Need
The ingredients for this casserole are straightforward but pack a big punch in flavor and texture. Each one plays a key role — from the crispy hash browns forming the perfect base, to the colorful bell peppers adding sweetness and crunch, to the rich blend of cheeses giving that irresistible gooey finish.
- Frozen shredded hash browns (30 oz, thawed): The crispy, golden foundation of the casserole that provides great texture.
- Olive oil (1 tablespoon): Used for sautéing veggies and adding a subtle fruitiness.
- Small onion (diced): Adds a mellow sweetness and aromatic depth.
- Red and green bell peppers (diced): Bring vibrant color and fresh crunch.
- Breakfast sausage or bacon (1 pound, cooked and crumbled): Infuses the dish with smoky, savory richness.
- Shredded cheddar cheese (2 cups): Sharp and melty, it’s a flavor superstar here.
- Shredded mozzarella cheese (1 cup): Provides creamy meltiness that balances the cheddar.
- Large eggs (10): The binding force that keeps it all together with fluffy texture.
- Milk (1 cup): Added to the eggs for smoothness and moisture.
- Garlic powder (½ teaspoon), onion powder (½ teaspoon), salt (½ teaspoon), black pepper (¼ teaspoon): Essential seasonings to bring out every flavor.
- Nonstick cooking spray: Helps ensure your casserole comes out spotless from the dish.
How to Make Delicious Hash Brown Egg Casserole Recipe
Step 1: Prepare Your Oven and Dish
Begin by preheating your oven to a warm 375°F. Take a 9×13-inch baking dish and grease it generously with nonstick cooking spray to prevent any sticking and to help your casserole come out beautifully.
Step 2: Sauté the Vegetables
In a large skillet, heat that tablespoon of olive oil over medium heat. Toss in the diced onion and both red and green bell peppers, cooking them gently until they soften up and become fragrant — about 5 minutes. This step caramelizes the veggies slightly, adding layers of flavor to your casserole.
Step 3: Whisk the Egg Mixture
In a large bowl, whisk together the 10 large eggs and 1 cup of milk until smooth. Add garlic powder, onion powder, salt, and black pepper. This well-seasoned egg mixture will soak into all the layers, tying the casserole together with creamy richness.
Step 4: Layer Your Casserole
Spread the thawed hash browns evenly across the bottom of your greased baking dish — this forms the crispy base we’re all craving. Next, scatter the cooked and crumbled sausage or bacon evenly on top. Follow with your sautéed onion and pepper mix. Then, sprinkle both the shredded cheddar and mozzarella cheeses evenly to cover the layer of veggies.
Step 5: Pour and Bake
Pour the egg mixture carefully and evenly over the entire layered dish. Give the pan a gentle shake to help the eggs settle through every crevice. Pop it into the oven and bake for 45 to 50 minutes until the eggs are set and the top turns a gorgeous golden brown. Let it rest for 5 to 10 minutes before slicing so everything firms up perfectly — that’s the moment when your Delicious Hash Brown Egg Casserole Recipe really shines.

Garnishes
Sprinkle freshly chopped parsley or green onions on top right before serving for a pop of color and a bit of fresh bite that complements the richness. A dash of hot sauce or a dollop of sour cream can also elevate the flavors beautifully if you love a tangy or spicy kick with your breakfast.
Side Dishes
This casserole pairs perfectly with a fresh fruit salad or a light green salad to balance the richness with brightness. For a cozy brunch, add warm crusty bread or toasted English muffins for a complete and satisfying meal.
