Ingredients You'll Need
Gathering your ingredients is the first step towards creating this incredible breakfast experience. Most items are likely already in your pantry or fridge!
For the Casserole:
- 1 pound breakfast sausage (choose mild or spicy to suit your palate)
- 8 large eggs
- 2 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 cup shredded cheddar cheese (or a melty blend like Colby Jack)
- 4 cups frozen hash browns (the shredded variety works best, but diced potatoes can also be used)
- 1 cup diced bell peppers (any color, for a pop of color and freshness)
- 1 cup diced onions (to deepen the savory flavor)
- 1/2 cup chopped green onions (for garnish, optional but recommended)
Step-by-Step Guide to Perfection
Follow these simple steps to create a show-stopping breakfast casserole:
Step 1: Get Your Oven Ready
Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish with cooking spray or butter to prevent sticking.
Step 2: Cook the Sausage
In a large skillet, cook the breakfast sausage over medium heat. Break it up with a spoon as it browns, ensuring it's fully cooked through. Once done, drain any excess grease thoroughly. Draining the fat is an important step in making a great casserole, ensuring it's not overly greasy. Set the cooked sausage aside.
Step 3: Prepare the Egg Mixture
In a spacious mixing bowl, whisk together the large eggs, milk, salt, black pepper, garlic powder, and onion powder until the mixture is completely uniform and slightly frothy.
Step 4: Combine All Ingredients
Add the cooked sausage, frozen hash browns, diced bell peppers, diced onions, and half of the shredded cheddar cheese to the egg mixture. Stir gently until all ingredients are evenly distributed and coated in the egg mixture.
Step 5: Transfer to Baking Dish
Pour the entire mixture into your prepared baking dish, spreading it out evenly. Sprinkle the remaining shredded cheddar cheese generously over the top.
Step 6: Bake Until Golden
Bake in the preheated oven for 45-55 minutes. The casserole is ready when the center is set, the eggs are cooked through, and the top is a beautiful golden brown. To test for doneness, a knife inserted into the center should come out clean.
Step 7: Cool and Garnish
Allow the baked casserole to rest for about 10 minutes before slicing and serving. This resting time helps it set beautifully. Garnish with chopped green onions for a fresh finish.
Tips for the Ultimate Breakfast Casserole
- Don't Overmix: While you want ingredients evenly distributed, don't overmix the eggs; this can make them tough.
- Seasoning Adjustments: Taste the sausage before adding salt to the egg mixture, especially if using a pre-seasoned sausage.
- Prevent Soggy Hash Browns: If using fresh potatoes, par-cook them slightly before adding them to ensure they are tender. For frozen, no need to thaw!
