Ingredients You’ll Need
The beauty of this recipe lies in its straightforward ingredients, each playing a key role to build the perfect balance of flavors, textures, and colors. They’re pantry staples with a fresh touch of spinach, resulting in a wholesome and bright casserole that’s hard to resist.
- 8 large eggs: The protein-packed base that gives this casserole its fluffy, custard-like texture.
- 1 cup whole milk: Adds creaminess and moisture to keep the eggs tender and rich.
- 1 cup shredded cheddar cheese: Provides melty, sharp flavor and beautiful color.
- 1/2 cup grated Parmesan cheese: A salty, nutty punch that deepens the overall taste.
- 1 1/2 cups chopped fresh spinach (or 1 cup frozen, thawed and drained): Brings freshness and a vibrant green contrast to the dish.
- 1/2 tsp salt: Enhances all the flavors and balances the richness.
- 1/4 tsp black pepper: Adds just the right amount of mild heat and depth.
- 1/2 tsp garlic powder: Lends a subtle savory aroma that pairs beautifully with cheese.
- 1/4 tsp onion powder: Complements the garlic and boosts the overall seasoning.
- 1 tbsp olive oil (for greasing the dish): Prevents sticking and adds a gentle fruity note to the crust.
How to Make Baked Spinach and Cheese Egg Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C). While it warms, lightly grease a 9×9-inch baking dish with olive oil. This small step ensures your casserole will slide out easily after baking and have a slightly crispy edge that adds to the dish’s appeal.
Step 2: Whisk the Egg Mixture
In a large bowl, beat together the eggs and whole milk until the mixture looks smooth and well combined. This is where the magic begins—getting a creamy base that will bake up soft and luscious.
Step 3: Add Cheese, Spinach, and Seasonings
Next, stir in the shredded cheddar, grated Parmesan, and chopped spinach along with the salt, pepper, garlic powder, and onion powder. Mixing these ingredients evenly throughout is key because each bite should deliver a perfect harmony of cheese, greens, and seasoning.
Step 4: Pour and Smooth
Transfer the mixture into your prepared baking dish, then gently smooth the top with a spatula so it bakes evenly. This ensures your casserole will have an inviting, golden surface once baked.
Step 5: Bake to Perfection
Pop your dish into the oven and bake for 30 to 35 minutes. You’ll know it’s done when the center sets firmly and the top turns a gorgeous golden brown. This is where your kitchen will start smelling heavenly—cheesy, garlicky, and just a touch earthy from the spinach.
Step 6: Cool and Serve
Allow the casserole to cool for 5 to 10 minutes before slicing. This helps it set up further, making it easier to cut neat portions. Then, get ready to enjoy a dish that’s warm, comforting, and packed with flavor.
How to Serve Baked Spinach and Cheese Egg Casserole Recipe
Garnishes
To elevate this casserole even more, consider topping each serving with a sprinkle of fresh chopped herbs like parsley or chives. A dollop of sour cream or Greek yogurt adds creamy tanginess that balances the richness beautifully.
Side Dishes
This casserole pairs wonderfully with a fresh fruit salad or sliced avocado for a bright, healthy contrast. On the heartier side, toasted crusty bread or a simple mixed greens salad with a light vinaigrette round out the meal perfectly.
Creative Ways to Present
Make your brunch table shine by serving the casserole in individual ramekins or mini muffin tins for perfectly portioned bites. You can also sprinkle some extra cheese and herbs on top before baking to add that wow factor visually and flavor-wise.
Make Ahead and Storage
Storing Leftovers
Once cooled, store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually meld nicely overnight, making for a delicious next-day breakfast or snack.
Freezing
This casserole freezes beautifully. Wrap individual slices tightly in plastic wrap and aluminum foil or place them in freezer-safe containers. They can be kept frozen for up to 1 month without losing their texture or taste.
Reheating
To reheat, warm slices in the microwave on medium power for about 1 to 2 minutes or until heated through. Alternatively, reheat in a preheated oven at 350°F (175°C) for 10 to 15 minutes for a crispier finish.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just make sure to thaw the frozen spinach completely and squeeze out as much moisture as possible to prevent the casserole from becoming soggy.
Is this casserole suitable for meal prepping?
Yes, this Baked Spinach and Cheese Egg Casserole Recipe is ideal for meal prepping because it keeps well and reheats nicely. It’s great for preparing ahead and enjoying throughout the week.

What can I add to make it more filling?
Consider mixing in cooked sausage, diced ham, or sautéed mushrooms for extra protein and texture to transform this casserole into a more substantial meal.
How do I know when the casserole is fully cooked?
The casserole is ready when the center is set and no longer jiggly, and the top has turned a lovely, golden brown. You can also insert a knife in the center — it should come out clean.
