Ingredients

Servings4

Yields 4 servings

  • (6 slices) whole grain bread
  • (2 cups) fresh spinach, chopped
  • (1 cup) shredded cheddar cheese
  • (1 cup) shredded mozzarella cheese
  • (6) large eggs
  • (2 cups) milk
  • (1 teaspoon) salt
  • (1/2 teaspoons) black pepper
  • (1/2 teaspoons) garlic powder
  • (1/2 teaspoons) onion powder
  • (1 tablespoon) olive oil
  • (1/4 cups) grated Parmesan cheese

Instructions

  1. 1

    Preheat the oven to 350°F (175 °C).

  2. 2

    In a skillet, heat 1 tablespoon of olive oil over medium heat. Add 2 cups of chopped fresh spinach and sauté until wilted, about 2-3 minutes. Remove from heat and let cool slightly.

  3. 3

    In a large mixing bowl, whisk together 6 large eggs, 2 cups of milk, 1 teaspoon of salt, 1/2 teaspoon of black pepper, 1/2 teaspoon of garlic powder, and 1/2 teaspoon of onion powder until well combined. Add 1 teaspoon salt, 2/4 teaspoon black pepper, 2/4 teaspoon garlic powder, and 2/4 teaspoon onion powder.

  4. 4

    Cut 6 slices of whole grain bread into cubes and add them to the egg mixture, stirring gently to coat the bread evenly.

  5. 5

    Add the sautéed spinach, 1 cup of shredded cheddar cheese, and 1 cup of shredded mozzarella cheese to the bowl. Mix everything together until combined.

  6. 6

    Transfer the mixture into a greased 9x13 inch baking dish, spreading it out evenly. Sprinkle 1/4 cup of grated Parmesan cheese on top.

  7. 7

    Cover the baking dish with plastic wrap and refrigerate for at least 1 hour, or overnight for best results.

  8. 8

    When ready to bake, remove the plastic wrap and place the baking dish in the preheated oven. Bake for 45-50 minutes, or until the strata is puffed and golden brown on top.

  9. 9

    Let it cool for 10 minutes before slicing and serving.
