Looking for a quick, healthy, and delicious breakfast or brunch option? This easy egg casserole is packed with nutritious vegetables, protein, and just the right amount of cheese. It’s a versatile dish that can be customized to your preferences, making it a go-to meal for busy mornings or weekend gatherings. Plus, it’s gluten-free and can easily be adapted to be dairy-free or vegetarian!

Ingredients:

  • 1 tsp olive oil
  • 1 tbsp garlic, minced
  • 1 tbsp shallot, finely chopped
  • 1/2 cup bell pepper, diced
  • Salt and pepper to taste
  • 1 small zucchini, diced
  • 3 large eggs
  • 3 tbsp whole milk (or any milk of your choice)
  • 1/4 cup broccoli, chopped
  • 1/4 cup mozzarella cheese, shredded
  • 5-6 slices of pepperoni (or substitute with chicken, steak, tofu, etc.)

Instructions:

  1. Preheat Your Oven: Set your oven to 350°F (175°C) and let it preheat while you prepare the casserole.
  2. Sauté the Vegetables: In a pan, heat 1 tsp of olive oil over medium heat. Add the minced garlic and chopped shallot, sautéing until fragrant and golden, about 2-3 minutes. Then, toss in the diced bell pepper, season with salt and pepper, and cook until the pepper softens slightly, around 5 minutes. Transfer the sautéed mixture to your casserole dish.
  3. Brown the Zucchini: Using the same pan, lightly brown the diced zucchini. This should take about 4-5 minutes, ensuring the zucchini is tender but not too soft. Once browned, add the zucchini to the casserole dish.
  4. Prepare the Egg Mixture: In a mixing bowl, whisk together 3 eggs, 3 tbsp of whole milk, and a pinch of salt and pepper. If you prefer a lighter option, you can use water instead of milk, though this will result in a less creamy texture.
  5. Assemble the Casserole: Pour the egg mixture evenly over the sautéed vegetables in the casserole dish. Top with 1/4 cup of chopped broccoli, followed by 1/4 cup of shredded mozzarella cheese. Add the slices of pepperoni or your preferred protein alternative on top. For a cheesier casserole, you can add a thin layer of extra mozzarella over the protein.
  6. Bake: Place the casserole dish in the preheated oven and bake for 35 minutes, or until the eggs are fully set and the cheese is bubbly and golden.
  7. Serve and Enjoy: Let the casserole cool slightly before slicing. Serve warm and enjoy a wholesome, satisfying meal!


Tips for Customization:

  • Vegetarian Option: Skip the pepperoni and load up on more veggies like spinach, mushrooms, or tomatoes.
  • Dairy-Free: Use a plant-based milk alternative and dairy-free cheese to make this casserole dairy-free.
  • Protein Swap: Experiment with different proteins like grilled chicken, turkey sausage, or even tofu for a healthier twist.
