Ingredients

• 8 large eggs

• 1 cup milk

• 1 teaspoon salt

• ½ teaspoon black pepper

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• 1 cup shredded cheddar cheese

• ½ cup shredded mozzarella cheese

• 1 cup broccoli florets, chopped

• 1 bell pepper, diced

• ½ cup diced onion

• 1 cup sliced mushrooms

• 1 tablespoon olive oil

• 1 teaspoon dried oregano

• 1 teaspoon dried basil

• Optional: chopped spinach, zucchini, or tomatoes for extra color and nutrition

Directions

1. Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with olive oil or non-stick spray.

2. Prepare the vegetables: In a medium skillet, heat olive oil over medium heat. Add onions, bell peppers, mushrooms, and broccoli. Sauté for 5-7 minutes until vegetables are tender but still crisp. Season with a pinch of salt and black pepper.

3. Whisk the eggs and milk: In a large bowl, combine eggs, milk, salt, black pepper, garlic powder, and onion powder. Whisk until fully blended and slightly frothy.

4. Assemble the casserole: Spread the sautéed vegetables evenly in the greased baking dish. Sprinkle half of the cheddar and mozzarella cheeses over the veggies. Pour the egg mixture on top, ensuring it covers the vegetables evenly. Top with the remaining cheeses and sprinkle dried oregano and basil over the casserole.

5. Bake: Place the casserole in the preheated oven and bake for 35-40 minutes, or until the eggs are fully set and the top is golden brown. A knife inserted in the center should come out clean.

6. Cool slightly and serve: Allow the casserole to cool for 5-10 minutes before slicing. This helps it set perfectly and makes serving easier.

Tips for the Perfect Casserole

• Use fresh vegetables: Fresh, crisp vegetables provide the best flavor and texture. Frozen vegetables can be used but may release extra water, which can affect the creamy texture.

• Cheese variations: Feel free to mix cheeses according to your taste. Monterey Jack, Colby, or Gruyère can add different flavor notes.

• Make it ahead: This casserole is perfect for meal prep. Assemble it the night before, cover with foil, and refrigerate. Bake it the next morning for a quick and satisfying breakfast.

• Add protein: For extra heartiness, consider adding cooked chicken, turkey, or even a few cooked lentils or beans for a vegetarian protein boost.

• Customize your veggies: Don’t hesitate to swap or add seasonal vegetables like asparagus, zucchini, or cherry tomatoes. The colorful mix makes the dish even more visually appealing.

Frequently Asked Questions

Can I make this casserole vegetarian?
Absolutely! This recipe is naturally vegetarian when prepared without any meat. The combination of eggs, cheese, and fresh vegetables provides plenty of flavor and protein, making it a satisfying meal on its own. You can further customize it to suit your dietary preferences by adding plant-based cheeses, non-dairy milk, or even tofu for extra protein. For example, swapping out traditional cheddar for a vegan cheddar or mozzarella can make this casserole completely plant-based without compromising its creamy, cheesy texture. Additionally, you can experiment with a wide variety of vegetables, from leafy greens like kale and spinach to colorful bell peppers and zucchini. This flexibility allows you to create a casserole that is both nutritious and perfectly tailored to your tastes.

Can I prepare this casserole ahead of time?
Yes! One of the best things about this casserole is its make-ahead convenience. You can assemble it the night before, cover it tightly with foil or plastic wrap, and refrigerate it until you’re ready to bake. This is a lifesaver for busy mornings, brunch parties, or holiday gatherings when you want a stress-free dish that’s ready to go. Baking it fresh in the morning will ensure the eggs are fluffy and the cheese is perfectly melted. You can even pre-chop all your vegetables and shred your cheese ahead of time to make the morning prep even quicker. For added convenience, you can store individual portions in small containers for grab-and-go breakfasts during the week.

Can I freeze this casserole?
Yes, this casserole freezes exceptionally well, making it a great option for meal prep. After baking, allow it to cool completely, then wrap it tightly in aluminum foil or plastic wrap and place it in an airtight container. It can be frozen for up to 2 months without losing flavor or texture. To reheat, thaw it overnight in the refrigerator and bake at 350°F (175°C) until warmed through. Freezing works best with casseroles that are fully cooked; however, you can also freeze it unbaked. If freezing unbaked, cover tightly and bake from frozen, adding a few extra minutes to the cooking time.

What vegetables work best in this casserole?
This casserole is incredibly versatile, and you can use virtually any combination of vegetables you love. Broccoli, bell peppers, mushrooms, onions, zucchini, and spinach are classic choices that balance flavor, texture, and nutrition. You can mix and match depending on what’s in season or what your family prefers. For added color and flavor, consider adding cherry tomatoes or roasted carrots. However, be cautious with high-water-content vegetables such as cucumbers or raw tomatoes, as they can release moisture during baking and make the casserole watery. Sautéing firmer vegetables beforehand helps maintain the perfect creamy texture while enhancing their natural flavors.

Conclusion

The Creamy Cheese and Veggie Egg Casserole is more than just a breakfast dish—it’s a versatile, wholesome, and satisfying meal that can brighten any morning or brunch gathering. With its rich, cheesy flavor, colorful vegetables, and comforting texture, it’s the perfect recipe to share with family and friends.
