- 3 large eggs: They bind the casserole together, giving it structure and richness.

- 1/3 cup crumbled feta: Offers a sharp, salty contrast that wakes up the flavors beautifully.
- 1/3 cup diced sweet onion: Contributes a mild sweetness and subtle crunch for balance.
- 1/4 cup melted butter: Adds richness and helps meld all the ingredients into a luscious casserole.
- 2 tablespoons freshly grated Parmesan: Introduces a nutty, savory depth that complements the feta perfectly.
- 1/8 teaspoon black pepper: Provides just enough gentle heat to enhance, not overpower.
- 1/8 teaspoon garlic powder: Delivers a soft garlicky warmth that lingers in the background.
- Dash of nutmeg: A subtle hint that elevates the spinach and cheese combination with its earthy warmth.
How to Make Spinach Casserole with Feta and Parmesan Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 350°F (175°C). Grease a 9-inch square casserole dish thoroughly to ensure your casserole doesn’t stick and comes out with clean edges for perfect serving squares.
Step 2: Mix All Ingredients
In a large mixing bowl, beat the three eggs until smooth. Add the cottage cheese, well-drained spinach, crumbled feta, diced sweet onion, melted butter, freshly grated Parmesan, black pepper, garlic powder, and a dash of nutmeg. Stir everything together gently but thoroughly, making sure each bite will be packed with flavor and textured with creamy, cheesy goodness.
Step 3: Bake to Perfection
Pour this beautifully blended mixture into your prepared casserole dish. Spread it evenly and place it in the oven, uncovered. Bake for 40 to 45 minutes, or until the center is almost set but still slightly wobbly to the touch. This ensures a creamy inside with a light golden top, inviting you when it’s fresh from the oven.
Step 4: Cool and Serve
Once baked, let your casserole rest for 5 to 10 minutes. This cool-down period helps it firm up just enough to slice into neat squares without losing any of its creamy charm. Serve it warm and watch it disappear fast!

Garnishes
To elevate the presentation and flavor, consider sprinkling some freshly chopped parsley or chives on top. A drizzle of good quality olive oil or a few crunchy toasted pine nuts can add texture and freshness, making each serving even more inviting.
Side Dishes
This casserole pairs wonderfully with roasted garlic potatoes, a crisp garden salad, or some lightly sautéed mushrooms. These sides enhance the richness while keeping the meal balanced, ensuring it feels luxurious without being heavy.
Creative Ways to Present
Serve your Spinach Casserole with Feta and Parmesan Recipe in rustic ramekins for a charming individual portion experience. Alternatively, layer it in a trifle dish with alternating layers of roasted veggies for a stunning visual that’s perfect for potlucks or holiday tables.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover the casserole tightly with plastic wrap or transfer it to an airtight container. Keep leftovers in the refrigerator for up to 3 days. The flavors continue to meld beautifully, often tasting even better the next day.
Freezing
This casserole freezes exceptionally well. Portion it out into freezer-safe containers or wrap tightly with foil and plastic wrap. Label and freeze for up to 2 months. When you’re ready to enjoy it again, thaw overnight in the fridge before reheating.
Reheating
Reheat individual portions in the microwave for 1 to 2 minutes or warm the entire casserole in a 325°F oven, covered, until heated through. Adding a sprinkle of extra Parmesan on top during reheating will refresh the cheesy appeal and keep the top golden.
FAQs
Can I use fresh spinach instead of frozen?
Yes, you can! Just be sure to wilt the fresh spinach in a pan first and squeeze out as much moisture as possible to prevent the casserole from becoming watery.
Is this casserole gluten-free?
Absolutely! All the ingredients in this Spinach Casserole with Feta and Parmesan Recipe are naturally gluten-free, making it a safe and delicious option for gluten-sensitive eaters.
Can I substitute the cottage cheese?
You can substitute ricotta cheese if you prefer a smoother texture, but cottage cheese adds a nice lightness and slight tang that works beautifully here.
How can I make this casserole vegan?
To make it vegan, replace the eggs with a flaxseed or chia egg substitute, use a plant-based cottage cheese alternative, and opt for vegan feta and Parmesan substitutes. Keep in mind the texture and flavor will be different but still enjoyable.
What’s the best way to reheat leftovers without drying them out?
Cover the casserole with foil while reheating in the oven and consider adding a tiny splash of milk or cream on top before warming. This helps maintain moisture and keeps the dish creamy.
