How to Make Easy Egg Florentine Breakfast Casserole

1. Preheat the oven:
   Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking dish (or similar-sized casserole dish) with cooking spray or butter.
2. Prepare the spinach:
   In a large skillet, heat the olive oil over medium heat. Add the chopped spinach and sauté for 3-4 minutes, until wilted and softened. Remove from heat and set aside to cool slightly.
3. Mix the eggs:
   In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until fully combined.
4. Assemble the casserole:
   In the prepared baking dish, layer the cubed bread evenly on the bottom. Spread the sautéed spinach over the bread, then pour the egg mixture over the spinach and bread. Sprinkle the shredded mozzarella cheese and grated Parmesan cheese evenly over the top.
5. Bake the casserole:
   Bake the casserole in the preheated oven for 30-35 minutes, or until the eggs are set and the top is lightly golden. If you insert a toothpick into the center, it should come out clean when the casserole is done.
6. Cool and serve:
   Let the casserole cool for 5 minutes before slicing into squares. If desired, garnish with fresh herbs like parsley or basil for an extra pop of color.

Tips For Easy Egg Florentine Breakfast Casserole

• Use day-old bread: Using slightly stale bread helps the casserole hold its shape and absorb the egg mixture, making the casserole even more flavorful and moist.
• Make it ahead: You can assemble the casserole the night before, cover it with plastic wrap, and refrigerate overnight. Then, just bake it the next morning for a quick breakfast.
• Add protein: If you’d like to add more protein, you can toss in cooked sausage, bacon, or chicken, or add some feta cheese for extra flavor.
• Customize the veggies: You can swap the spinach for other leafy greens like kale or Swiss chard, or add other vegetables like bell peppers, mushrooms, or onions for a more hearty dish.

Substitutions and Variations

• Gluten-free option: To make the casserole gluten-free, use gluten-free bread cubes or omit the bread entirely and substitute with cooked quinoa or cauliflower rice for a low-carb option.
• Dairy-free version: Use dairy-free cheese and milk (such as almond or oat milk) for a dairy-free version of this casserole.
• Vegetarian version: This casserole is already vegetarian, but you can make it vegan by replacing the eggs with a plant-based egg substitute and using dairy-free cheese.

Make a Healthier Version

• Low-fat option: Use low-fat milk and cheese to reduce the fat content, or skip the cheese altogether for a lighter casserole.
• Increase veggies: Add more vegetables like mushrooms, zucchini, or tomatoes to increase the fiber and nutrient content.
• Lower-carb: Use low-carb bread or omit the bread entirely to make this casserole even lower in carbs.
