- In a large mixing bowl, whisk together the eggs and milk. Season with salt and pepper.
- Fold in the cubed bread, cooked sausage, diced bell pepper, and chopped onion into the egg mixture. Stir until everything is well combined.
- Grease a 9×13-inch baking dish and pour the mixture into it. Spread it evenly with a spatula.
- Top with shredded cheese.
- Bake in the preheated oven for about 30-35 minutes, or until the eggs are set and the cheese is bubbly and golden.
- Let it cool for a few minutes before slicing and serving. Garnish with fresh herbs if desired.

Pro Tips for Success Breakfast Casserole
- Choose the Right Bread: Stale or day-old bread works best as it soaks up the egg mixture without getting too soggy.
- Customize Your Veggies: Feel free to add other vegetables such as spinach, mushrooms, or zucchini for added flavor and nutrition.
- Use Cheese Wisely: Use a combination of cheeses for a richer flavor. Just be cautious of the quantity to avoid getting too greasy.
- Let It Rest: Allow your casserole to sit for 5-10 minutes after baking before serving. It helps the layers to settle and makes slicing easier.
- Make-ahead Option: Assemble the casserole the night before and refrigerate it. Bake it in the morning for a quick breakfast.
Flavor Variations Breakfast Casserole
- Southwestern Twist: Add black beans, corn, and taco seasoning. Top with pepper jack cheese for some heat.
- Mediterranean Style: Incorporate spinach, feta cheese, and sun-dried tomatoes for a refreshing change.
- Italian Flair: Combine Italian sausage, diced tomatoes, and basil to provide an Italian-inspired meal.
- Veggie Delight: Use a variety of seasonal vegetables such as broccoli, carrots, and bell peppers, omitting the sausage for a meat-free version.
- Smoky Flavor: Add smoked paprika and use smoked gouda to create a subtly smoky breakfast.
Serving Suggestions Breakfast Casserole
This breakfast casserole is delightful on its own but can be elevated with additional sides. Consider serving it with:
- Fresh fruit salad for a refreshing contrast.
- A side of crispy bacon or turkey bacon for extra protein.
- Sweet pastries or pancakes for a more indulgent brunch option.
- A simple green salad to balance out the meal.

Leftover breakfast casserole can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, you can freeze individual portions. Just make sure to wrap slices tightly in plastic wrap and foil, and store them in a freezer-safe bag.

FAQ About Breakfast Casserole
Can I use different types of meat in the casserole?
Absolutely! You can substitute the sausage with other proteins like diced chicken, ground turkey, or even plant-based sausage if you’re looking for a vegetarian option. Just ensure they are cooked thoroughly before mixing them into the casserole.
Can I prepare the casserole the night before?
