Description

This hearty Vegetable Breakfast Casserole is a nutritious and flavorful start to your day, combining sautéed fresh vegetables with eggs and cheddar cheese for a wholesome, satisfying meal. Perfect for make-ahead mornings and adaptable with your favorite veggies.


Ingredients

Scale

Vegetables

  • 1 tablespoon olive oil
  • 1 small onion, diced
  • 1 red bell pepper, diced
  • 1 green bell pepper, diced
  • 1 zucchini, chopped
  • 1 cup chopped fresh spinach

Seasonings

  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Egg Mixture

  • 8 large eggs
  • 1/2 cup milk (dairy or non-dairy)
  • 1 cup shredded cheddar cheese

Optional Garnish

  • Chopped green onions or fresh herbs


Instructions

  1. Preheat and Prepare: Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish to ensure the casserole doesn’t stick during baking.
  2. Sauté Vegetables: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add diced onion, red and green bell peppers, and chopped zucchini. Cook for 5 to 7 minutes until the vegetables are softened and fragrant.
  3. Add Spinach and Season: Stir in the chopped fresh spinach and cook for 1 to 2 more minutes until wilted. Season the mixture with garlic powder, salt, and black pepper. Remove the skillet from heat.
  4. Mix Eggs and Milk: In a large bowl, whisk together 8 large eggs and 1/2 cup milk until smooth and fully combined.
  5. Combine Ingredients: Fold the cooked vegetable mixture and 1 cup shredded cheddar cheese into the egg mixture, ensuring everything is evenly distributed.
  6. Assemble Casserole: Pour the combined mixture into the prepared baking dish and spread it out evenly.
  7. Bake: Place the baking dish in the oven and bake for 30 to 35 minutes, or until the center is set and the top turns lightly golden brown.
  8. Cool and Garnish: Allow the casserole to cool slightly before slicing. Garnish with chopped green onions or fresh herbs if desired, then serve warm.

Notes

  • Prepare the casserole the night before and refrigerate, then bake fresh in the morning for convenience.
  • Feel free to swap in any vegetables you have on hand, such as mushrooms, broccoli, or tomatoes, to customize the dish.
