Description

This Baked Spinach and Cheese Egg Casserole is a deliciously hearty and nutritious breakfast or brunch option. Combining fluffy eggs with creamy cheeses and fresh spinach, this casserole offers a perfect balance of flavors and textures. Easy to prepare and bake, it makes for an ideal make-ahead dish that serves six comfortably.

Ingredients

Egg Mixture

  • 8 large eggs
  • 1 cup whole milk

Cheeses

  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese

Vegetables & Seasonings

  • 1 1/2 cups chopped fresh spinach (or 1 cup frozen spinach, thawed and drained)
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1/2 tsp garlic powder
  • 1/4 tsp onion powder

For Greasing

  • 1 tbsp olive oil

Instructions

  1. Preheat and Prepare Baking Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch or similar baking dish with the olive oil to prevent the casserole from sticking.
  2. Mix Eggs and Milk: In a large bowl, whisk together the 8 eggs and 1 cup of whole milk until the mixture is smooth and homogenous, ensuring an even custard base for the casserole.
  3. Add Cheese and Spinach: Stir in the shredded cheddar, grated Parmesan, chopped fresh spinach, salt, pepper, garlic powder, and onion powder. Mix thoroughly to combine all ingredients uniformly.
  4. Pour into Baking Dish: Pour the prepared mixture into the greased baking dish, smoothing the top for even cooking and a nice finish.
  5. Bake the Casserole: Place the dish in the oven and bake for 30 to 35 minutes. Bake until the center is fully set and the top has developed a golden brown color, indicating it is cooked through.
  6. Cool and Serve: Remove from oven and let the casserole cool for 5 to 10 minutes. This resting time helps it set further and makes slicing easier before serving.

Notes

  • You can substitute fresh spinach with frozen spinach, just ensure it is properly thawed and drained to avoid excess moisture.
  • Feel free to experiment with different cheeses like mozzarella or Swiss for a different flavor profile.
  • This casserole can be made in advance and refrigerated overnight; reheat before serving for convenience.
  • For a richer flavor, try adding chopped cooked bacon or sautéed mushrooms to the mixture.
  • Use a non-stick spray or butter as alternatives for greasing the baking dish if preferred.
