Step 1: Preheat the Oven
- Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with olive oil or cooking spray.
Step 2: Sauté the Spinach
- Cook the Onion and Garlic: Heat 1 tablespoon of olive oil in a large frying pan over medium heat. Add the diced onion and sauté for 3-4 minutes until softened. Add the garlic and cook for an additional 1 minute until fragrant.
- Add Spinach: Add the chopped spinach to the pan and cook for 2-3 minutes, stirring frequently, until the spinach wilts down. Remove from heat and set aside.
Step 3: Prepare the Egg Mixture
- Beat the Eggs: In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and any optional seasonings (oregano, red pepper flakes).
- Add Cheese: If you’re using cheese, fold in shredded cheddar and/or feta into the egg mixture.
Step 4: Assemble the Casserole
- Combine Ingredients: Add the cooked spinach, onion, and garlic mixture into the bowl with the egg mixture. Stir until everything is well combined.
- Pour into Baking Dish: Pour the egg and spinach mixture into the prepared baking dish, spreading it out evenly.
Step 5: Bake the Casserole
- Bake in the preheated oven for 25-30 minutes, or until the eggs are set and the top is slightly golden. If you insert a toothpick or knife into the center, it should come out clean.
Step 6: Serve and Garnish
- Cool and Garnish: Let the casserole cool for about 5 minutes before slicing. Garnish with freshly chopped parsley, if desired.
- Serve: Slice into squares and serve warm. This casserole pairs well with toast, a light salad, or even a side of bacon or sausage.
Tips for the Best Spinach Egg Casserole:
- Use Fresh or Frozen Spinach: Fresh spinach works best, but if you’re using frozen spinach, make sure to thaw and squeeze out excess water before adding it to the casserole.
- Add Protein: You can make this dish heartier by adding cooked bacon, sausage, or ham.
- Vegetable Additions: Feel free to add other vegetables like mushrooms, bell peppers, or zucchini to bulk up the casserole.
- Meal Prep Friendly: This casserole can be made ahead of time and stored in the fridge for up to 4 days. Reheat individual portions in the microwave or oven for a quick breakfast.
