Ingredients You’ll Need
Gathering the right ingredients is the first step to making this dish spectacular. Each simple item in this casserole plays a crucial role—whether it’s adding moisture, flavor, or that gorgeous golden top.
- 10 large eggs: The foundation of the casserole, providing a fluffy, protein-packed base.
- 1 cup whole milk: Adds creaminess and tenderizes the egg mixture for a soft bite.
- 1 teaspoon salt: Essential for enhancing all the flavors in the dish.
- ½ teaspoon black pepper: Gives a subtle kick and depth to the eggs.
- 1 teaspoon garlic powder: Adds warmth and a mild savory flavor throughout.
- 1 teaspoon onion powder: Complements the fresh onion and deepens the taste profile.
- 2 cups fresh spinach (chopped): Brings vibrant color and a healthy, earthy note.
- 1 cup shredded mozzarella cheese: Melts into gooey, stretchy goodness.
- ½ cup shredded cheddar cheese: Provides sharpness and a rich cheesy bite.
- ¼ cup grated Parmesan cheese: Adds a salty, nutty finish on top and inside.
- ½ small onion (finely diced): Offers a bit of crunch and sweetness.
- Nonstick cooking spray or butter: For greasing your baking dish and preventing sticking.
How to Make Baked Spinach and Cheese Egg Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9×13-inch baking dish with nonstick spray or butter. This step ensures your casserole doesn’t stick and develops that beautiful browned crust we all love.
Step 2: Whisk the Egg Mixture
In a large bowl, gently whisk together the eggs, whole milk, salt, pepper, garlic powder, and onion powder. Whisking thoroughly is key here—it blends the flavors well and creates the perfect airy texture for your casserole.
Step 3: Incorporate the Spinach, Onion, and Cheeses
Fold in the chopped fresh spinach and finely diced onion, then add your mozzarella, cheddar, and Parmesan cheeses. Mixing these ingredients evenly ensures that every slice of this casserole is bursting with flavor and has the perfect balance of gooey cheese and fresh greens.
Step 4: Bake Until Golden and Set
Pour the mixture into the greased baking dish and spread it out evenly. Place it in your oven and bake for 30 to 35 minutes. You’ll know it’s done when the egg center is set and the top is a glowing golden brown. Let it cool for about 5 minutes before slicing—it makes serving much easier.

Garnishes
For a fresh contrast, sprinkle the top with chopped fresh herbs such as parsley or chives. A light dusting of extra Parmesan can add a lovely salty crunch, or even a few cherry tomatoes on the side brighten each bite.
Side Dishes
This casserole pairs beautifully with crisp fruit salad for a fresh start, or some warm, crusty bread to sweep up every last cheesy morsel. For a heartier brunch, add some crispy bacon or sautéed mushrooms alongside.
Creative Ways to Present
You can turn this dish into a crowd-pleaser by serving it in individual ramekins or muffin tins for perfectly portioned mini casseroles. It’s also fabulous cut into squares and stacked in a brunch buffet for easy grabbing and sharing, making it great for holiday mornings or casual get-togethers.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your casserole tightly with plastic wrap or foil and store it in the refrigerator. It will keep well for up to 3 days, allowing you to enjoy quick, flavorful meals without the fuss.
Freezing
This casserole freezes beautifully. Wrap individual portions or the whole dish well with airtight freezer-safe wrap or containers. Freeze for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating.
Reheating
To reheat, simply microwave individual slices for about 1 to 2 minutes until warm, or place the whole dish in a preheated oven at 350 degrees Fahrenheit until heated through. This keeps the cheeses melty and the spinach vibrant.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just thaw it first, squeeze out any excess moisture, and then add it to your mixture. This keeps the casserole from becoming watery and maintains that wonderful spinach flavor.
Is this recipe gluten-free?
Yes! The Baked Spinach and Cheese Egg Casserole Recipe contains no gluten ingredients, making it a perfect gluten-free breakfast or brunch option.
Can I add meat to this casserole?
Definitely! Cooked bacon, sausage, or even diced ham can be stirred in with the spinach and cheese for an extra protein boost and heartier flavor profile.
What’s the best way to reheat leftovers without drying out the casserole?
Reheating gently is key. Microwave with a cover to trap moisture, or heat in the oven at a moderate temperature with foil over the top to prevent drying out.
How can I make this dish ahead of time for a busy morning?
Assemble the casserole the night before and store it in the refrigerator without baking. In the morning, just pop it into the oven and bake as directed. This makes breakfast effortless and delicious!
