Ingredients

• 10 large eggs

• 1 cup milk (whole or 2%)

• 2 cups fresh spinach, chopped

• 1 cup crumbled feta cheese

• 1 cup shredded mozzarella cheese

• ½ cup diced onion

• 1 red bell pepper, diced

• 2 cloves garlic, minced

• 1 teaspoon salt

• ½ teaspoon black pepper

• ½ teaspoon dried oregano

• ½ teaspoon paprika

• 1 tablespoon olive oil (for sautéing)

• Nonstick cooking spray or butter for greasing the baking dish

Directions

1. Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick spray or butter to ensure the casserole releases easily after baking.

2. Sauté the vegetables. In a medium skillet, heat olive oil over medium heat. Add the diced onion and red bell pepper, cooking for 3–4 minutes until softened. Stir in the minced garlic and chopped spinach, cooking just until the spinach wilts. Remove from heat and let it cool slightly.

3. Whisk the eggs and milk. In a large mixing bowl, whisk together the eggs, milk, salt, pepper, oregano, and paprika until fully combined and slightly frothy. This step ensures a light, airy texture once baked.

4. Add the cheeses and vegetables. Stir in the feta and mozzarella cheeses, then fold in the sautéed vegetable mixture. Mix gently until everything is evenly distributed.

5. Pour and bake. Pour the egg mixture into the prepared baking dish, spreading it out evenly. Bake for 35–40 minutes, or until the center is set and the top is golden brown.

6. Cool slightly before serving. Allow the casserole to rest for 5–10 minutes before slicing. This helps the layers firm up and makes serving easier.

Tips for Success

To make sure your Spinach and Feta Egg Casserole turns out perfectly every time, follow these tried-and-true tips:

1. Drain the spinach well. Whether you’re using fresh or frozen spinach, removing excess moisture prevents a soggy texture.

2. Use freshly grated cheese. Pre-shredded cheese often contains anti-caking agents that affect melting — freshly grated melts creamier and smoother.

3. Don’t overbake. The casserole should be set in the middle but still slightly jiggly. Overbaking can make it dry.

4. Let it rest before slicing. This helps the casserole firm up and hold its shape when served.

5. Add spices thoughtfully. Feta brings a natural saltiness, so taste before adding extra salt.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Yes! Frozen spinach works perfectly in this recipe. Just make sure to thaw it completely and squeeze out as much liquid as possible. Excess water can make the casserole watery instead of firm and fluffy.

Can I make this casserole ahead of time?

Absolutely. You can assemble it the night before and refrigerate it overnight. Simply bake it in the morning, adding a few extra minutes of cook time. It’s a wonderful make-ahead option for busy mornings or entertaining.

What kind of cheese works best in this recipe?

Feta provides the tangy, salty kick that makes this dish stand out, while mozzarella adds creamy texture. However, you can also use cheddar, Swiss, or Monterey Jack if you prefer a different flavor profile.

How do I know when the casserole is done baking?

The top should be golden brown, and the center should be set but still slightly jiggly. A knife inserted into the center should come out clean. If it looks wet or runny, give it a few more minutes in the oven.
