Ingredients You’ll Need
The magic of this casserole comes from a handful of basic, yet carefully chosen ingredients. Each one plays a vital role—from the rich creaminess of the eggs and cheese to the vibrant color and nutrition from the spinach, all seasoned just right for maximum flavor. You probably have most of these in your kitchen already!
- 8 large eggs: The protein-packed base that holds everything together with fluffy richness.
- 1 cup whole milk: Adds creaminess and moisture to keep the casserole tender and soft.
- 1 cup shredded cheddar cheese: Sharp and melty, it gives the dish its signature cheesy flavor.
- 1/2 cup grated Parmesan cheese: Introduces a nutty, salty depth that elevates the casserole’s taste.
- 1 (10-ounce) package frozen chopped spinach, thawed and squeezed dry: Provides vivid color and a boost of nutrients without extra effort.
- 1/2 teaspoon garlic powder: Brings a subtle warmth and savory undertone.
- 1/2 teaspoon onion powder: Adds complexity and a hint of sweetness to the mix.
- 1/4 teaspoon salt: Enhances all the flavors perfectly without overpowering them.
- 1/4 teaspoon black pepper: Offers a gentle kick that balances the richness.
- 1 tablespoon olive oil: For greasing your baking dish, adding a light fruity aroma.
- Optional: 1/4 cup diced onions or bell peppers: Adds a fresh crunch and colorful contrast if you want a little extra texture.
How to Make Baked Spinach and Cheese Egg Casserole Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 375 degrees Fahrenheit. While it warms up, grease a 9×9-inch baking dish with olive oil ensuring none of your cheesy, spinachy goodness sticks. This step is key for a perfectly baked bottom and easy serving.
Step 2: Whisk the Eggs and Milk
In a large bowl, combine 8 eggs and 1 cup of whole milk. Whisk them together energetically until the mixture is smooth and slightly frothy. This creates the creamy base for your casserole, giving it that melt-in-your-mouth texture.
Step 3: Add Cheese, Spinach, and Seasonings
To your egg mixture, fold in the shredded cheddar, grated Parmesan, thawed and squeezed-dry spinach, garlic powder, onion powder, salt, and pepper. If you’ve chosen to add diced onions or bell peppers, toss those in now as well. This blend of cheese and seasoned spinach makes every bite flavorful and vibrant.
Step 4: Pour and Bake
Pour the well-mixed combination into your prepared dish and spread it out evenly. Smooth it gently with a spatula for an even cook. Slide it into the oven and bake for 30 to 35 minutes. You’re looking for a golden top and a center that sets without a wobble—signs that all the flavors have beautifully melded together.
Step 5: Cool and Serve
Once baked, allow your casserole to cool for a few minutes before slicing. This resting time helps it firm up, making it easier to cut perfect squares and enhancing the texture when served.
How to Serve Baked Spinach and Cheese Egg Casserole Recipe
Garnishes
A sprinkle of freshly chopped herbs like parsley or chives adds a fresh pop of color and brightness that complements the rich, cheesy flavors perfectly. A light dusting of extra Parmesan on top just before serving amps up the savory notes.
Side Dishes
The versatility of this casserole means it pairs wonderfully with many sides. Think crisp mixed greens dressed lightly with vinaigrette for contrast, or fresh fruit salad to add a sweet, juicy balance. Crusty bread or warm English muffins make great accompaniments, especially for leisurely weekend brunches.
Creative Ways to Present
For a charming brunch presentation, serve individual slices on colorful plates with small ramekins of salsa or avocado slices on the side. You can also cut the casserole into bite-sized squares and offer them as savory finger foods for a breakfast gathering or potluck.
Make Ahead and Storage
Storing Leftovers
After enjoying your casserole, simply cover any leftovers tightly with plastic wrap or store in an airtight container. Keep it refrigerated for up to 3 days—making it a perfect make-ahead meal when mornings get hectic.
Freezing
If you want to stash some for later, this casserole freezes beautifully. Wrap individual portions or the whole dish tightly in foil and place in a freezer-safe container. It will keep well for up to 2 months, ready to thaw and enjoy whenever you need a quick breakfast fix.
Reheating
To reheat, place leftovers in a preheated 350-degree oven for about 15-20 minutes, or microwave individual slices for 1 to 2 minutes until warmed through. The casserole retains its creamy, cheesy goodness with no fuss.
FAQs
Can I use fresh spinach instead of frozen?
Yes, you absolutely can! Just sauté the fresh spinach until wilted and then drain any excess moisture before adding it to the mixture. This prevents your casserole from becoming watery and keeps the flavors concentrated.
What cheeses work best in this casserole?
Cheddar and Parmesan are fantastic together for sharpness and depth, but you can experiment with mozzarella for creaminess or feta for a tangy twist. Each cheese adds a unique character to this dish.
Is this casserole suitable for meal prep?
Definitely! It stores well in the fridge and reheats beautifully, making it an excellent option for preparing breakfasts or snacks ahead of time during a busy week.
Can I add meat to this egg casserole?
While this recipe is vegetarian-friendly, you’re free to add cooked sausage, bacon, or ham if you want to boost the protein and add extra flavor. Just fold it in before baking.
How can I make this casserole gluten-free?
Great news: this recipe is naturally gluten-free as it contains no flour or bread. Just be sure to use any optional added ingredients, like spices or cheese, that are labeled gluten-free for peace of mind.
