Starting your day with a hearty, flavorful breakfast is essential, and a 10 egg breakfast casserole offers a perfect solution for feeding a crowd or preparing ahead. This dish combines eggs, cheese, meats, and vegetables into a satisfying baked casserole that’s simple to customize and easy to make in advance.
Ingredients
- 10 large eggs
- 1 cup whole milk (or half-and-half for creamier texture)
- 1 cup shredded cheddar cheese
- 1 cup cooked breakfast sausage (or bacon, ham, or turkey sausage)
- 1 small onion, finely chopped
- 1 cup diced bell peppers (any color)
- 1 cup chopped spinach or kale (optional)
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon dried oregano or Italian seasoning
- Cooking spray or butter for greasing
Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish thoroughly with butter or cooking spray to prevent sticking.
- In a large mixing bowl, whisk together the eggs and milk until well combined and slightly frothy.
- Add the salt, pepper, and dried herbs to the egg mixture, stirring to incorporate evenly.
- Stir in the shredded cheese, cooked sausage, chopped onion, bell peppers, and spinach if using. Mix until all ingredients are evenly distributed.
- Pour the mixture into the prepared baking dish, spreading it out evenly with a spatula.
- Bake in the preheated oven for 35-40 minutes, or until the eggs are set and the top is golden brown. A toothpick inserted into the center should come out clean.
- Remove from oven and let it rest for about 5 minutes before slicing. This helps the casserole set and makes serving easier.
- Slice into squares and serve warm. You can garnish with additional cheese, herbs, or hot sauce if desired.
Tips
- Substitutions: Use cooked bacon or ham instead of sausage for different flavor profiles. Dairy-free options like almond milk and dairy-free cheese can be used for lactose intolerance.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave for 1-2 minutes or until heated through.
- Common mistakes: Not greasing the dish well can cause sticking; ensure thorough greasing. Overbaking can dry out the casserole, so keep an eye on the time and check for doneness.
- Additional tips: For a fluffier texture, whisk the eggs thoroughly and avoid overmixing once ingredients are combined.
Serving Suggestions
This breakfast casserole pairs wonderfully with fresh fruit, a side of toast, or a light mixed green salad. Consider serving with salsa or hot sauce for added flavor. It’s perfect for brunch gatherings, weekend breakfast, or meal prepping for busy mornings.
Variations
- Vegetarian: Skip the meat and add more vegetables like mushrooms, zucchini, or cherry tomatoes.
- Spicy: Mix in chopped jalapeños or red pepper flakes to add heat.
- Cheese options: Use a combination of cheeses such as Monterey Jack, mozzarella, or feta for different flavor profiles.
- Low-carb: Add more vegetables and omit high-carb ingredients like bread or potatoes.
Storage and Reheating
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions on high for 1-2 minutes, or until heated through. For larger portions, reheat in a 350°F (175°C) oven for about 15 minutes, covered with foil to prevent drying out.
Frequently Asked Questions
Can I prepare this casserole the night before?
Yes, you can assemble the casserole the night before and refrigerate it overnight. Just cover it tightly with plastic wrap and bake it in the morning. Add an extra 10 minutes to the baking time if baking directly from refrigerated state.
Can I freeze leftovers?
Absolutely. Allow the casserole to cool completely, then cut into portions and wrap each piece tightly in plastic wrap or foil. Store in a freezer-safe container or bag for up to 2 months. Thaw overnight in the refrigerator before reheating.
Is it necessary to use milk in the recipe?
The milk helps create a custard-like texture, but you can substitute with half-and-half, heavy cream, or plant-based milk depending on dietary preferences. Keep in mind that different liquids may alter the final texture slightly.
How do I know when the casserole is done?
The casserole is ready when the eggs are fully set and the top is golden brown. A toothpick inserted into the center should come out clean. The baking time is approximately 35-40 minutes at 350°F, but ovens vary, so start checking around 35 minutes.
Can I add other vegetables or meats?
Yes, feel free to customize with your favorite ingredients. Cooked mushrooms, zucchini, or even leftover roasted potatoes work well. For meats, cooked bacon, ham, or turkey sausage are excellent options. Just ensure all ingredients are cooked before mixing into the casserole.
What if I want a lower-fat version?
Use egg whites or a combination of whole eggs and egg whites to reduce fat content. Choose lean meats like turkey sausage or chicken. Use reduced-fat cheese and skim or low-fat milk to further cut calories.
