Ingredients
  

1 tablespoon olive oil

1 small onion, finely diced

2 cloves garlic, minced

5 cups fresh spinach, roughly chopped

6 large eggs

1 cup milk (whole or your preferred type)

1 cup shredded cheddar cheese

1 cup feta cheese, crumbled

1 cup cooked sausage (optional, feel free to use a plant-based alternative)

1 teaspoon salt

½ teaspoon black pepper

½ teaspoon crushed red pepper flakes (optional, for heat)

4 slices of whole grain bread, cut into 1-inch cubes

Fresh parsley, chopped (for garnish, optional)

Instructions
 

Preheat the Oven: Begin by preheating your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with non-stick cooking spray or a touch of olive oil to prevent sticking.

    Sauté the Aromatics: In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until translucent and soft. Stir in the minced garlic and cook for an additional minute until fragrant.

      Cook the Spinach: Add the chopped spinach to the skillet and cook, stirring frequently, until it wilts down, which should take about 2-3 minutes. Once wilted, remove the skillet from heat and let it cool slightly.

        Mix the Egg Base: In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and crushed red pepper flakes (if using) until well combined and fluffy.

          Combine Ingredients: Fold in the sautéed spinach and onion mixture to the egg mixture. If you're using sausage, add that as well along with the shredded cheddar and crumbled feta cheese.

            Incorporate the Bread: Gently fold the cubed whole grain bread into the mixture, ensuring each piece of bread is thoroughly coated with the egg mixture for a deliciously custardy texture.

              Transfer to Baking Dish: Pour the entire mixture into the prepared baking dish, spreading it out evenly to create a uniform layer.

                Bake the Casserole: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the casserole is firm in the center and lightly golden on top.

                  Cool and Garnish: Once out of the oven, allow the casserole to rest for a few minutes before slicing into squares. If desired, sprinkle freshly chopped parsley on top for a pop of color and freshness.

                    Serve and Enjoy: Serve warm as a hearty breakfast option that is sure to please everyone at the table!
