Ingredients for Breakfast Casserole
Here’s what you’ll need to make this delicious breakfast casserole:
- 6 large eggs
- 1 cup milk (or half-and-half for extra creaminess)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 2 cups shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1 lb breakfast sausage (or bacon, ham, or turkey sausage)
- 1 small onion, diced
- 1 bell pepper, diced
- 4 cups frozen hash browns (or diced potatoes)
- 1/4 cup chopped fresh parsley (optional, for garnish)
How to Make Breakfast Casserole – Step by Step
Follow these simple steps to create the perfect breakfast casserole:
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
Step 2: Cook the Meat and Veggies
In a large skillet, cook the breakfast sausage (or your choice of meat) over medium heat until browned. Add the diced onion and bell pepper, cooking until softened. Drain any excess grease and set aside.
Step 3: Mix the Eggs and Cheese
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder. Stir in 1 1/2 cups of the shredded cheddar cheese and the Parmesan cheese.
Step 4: Assemble the Casserole
Spread the frozen hash browns evenly in the prepared baking dish. Top with the cooked meat and veggie mixture. Pour the egg and cheese mixture over the top, ensuring everything is evenly coated. Sprinkle the remaining 1/2 cup of cheddar cheese on top.
Step 5: Bake to Perfection
Bake in the preheated oven for 35-40 minutes, or until the casserole is set and the top is golden brown. If you prefer a crispier top, broil for an additional 2-3 minutes.
Step 6: Rest and Serve
Let the casserole rest for 5-10 minutes before slicing. Garnish with chopped fresh parsley if desired, and serve warm.
Expert Tips for Perfect Results
To ensure your breakfast casserole turns out perfectly every time, keep these tips in mind:
- Use Room Temperature Ingredients: Allow eggs and milk to come to room temperature before mixing for a smoother texture.
- Customize Your Ingredients: Swap out meats or veggies based on what you have on hand or dietary preferences.
- Prep Ahead: Assemble the casserole the night before and refrigerate. Bake it in the morning for a fresh, hot breakfast.

Common Questions About Breakfast Casserole
Here are some frequently asked questions about making and enjoying breakfast casserole:

- Pre-Cook Your Veggies: Sautéing onions and bell peppers before adding them to the casserole enhances their flavor and ensures they cook evenly.
- Use a Mix of Cheeses: Combining cheddar and Parmesan creates a richer flavor profile. Experiment with other cheeses like Swiss or pepper jack for variety.
- Avoid Overmixing: When combining the egg mixture, stir just until everything is incorporated to keep the texture light and fluffy.
- Add a Crunchy Topping: Sprinkle crushed cornflakes or breadcrumbs on top before baking for added texture.
- Make It Spicy: Add a pinch of red pepper flakes or diced jalapeños to the egg mixture for a spicy kick.
- Use Leftover Ingredients: This casserole is a great way to use up leftover meats, veggies, or even cooked potatoes.
- Check for Doneness: Insert a knife into the center of the casserole. If it comes out clean, the casserole is ready.
- Let It Rest: Allowing the casserole to rest for a few minutes after baking makes it easier to slice and serve.
