- 3 large eggs: Eggs provide the perfect binding and lend a fluffy, rich texture.
- 2 tablespoons extra virgin olive oil: Olive oil enriches the casserole with fruity undertones and helps keep it moist.

How to Make Baked Zucchini Spinach and Feta Casserole
Step 1: Get Your Oven Ready and Dish Greased
Preheat your oven to 375°F (190°C). While it warms up, grease a baking dish with a little olive oil or non-stick spray. This ensures the casserole won’t stick and helps develop that gorgeous golden crust.
Step 2: Prepare the Veggies
Slice the zucchinis into thin rounds so they bake evenly and meld beautifully. Toss the zucchini slices together with the fresh spinach in a large mixing bowl. Combining them now ensures the greens are evenly distributed throughout your casserole.
Step 3: Whisk Together the Binding Mixture
In a separate bowl, whisk the eggs until smooth, then add the crumbled feta, garlic powder, salt, pepper, and olive oil. Mixing these ingredients ahead of time helps the flavors marry and gives the casserole a rich, savory base.
Step 4: Combine and Gently Mix
Pour the egg and feta mixture over your zucchini and spinach blend. Stir gently but thoroughly – you want every veggie slice to be coated so the casserole holds together well and every bite bursts with flavor.
Step 5: Transfer and Spread Evenly
Move the combined mixture to your greased baking dish. Spread it out evenly to ensure consistent cooking and that inviting golden top layer forms perfectly.
Step 6: Bake Until Golden and Set
Bake for 30 to 35 minutes. You’ll know it’s ready when the top turns an inviting golden brown and the casserole feels firm to the touch. This step transforms fresh ingredients into a cozy, satisfying dish that smells absolutely irresistible.
How to Serve Baked Zucchini Spinach and Feta Casserole

Garnishes
Fresh herbs like parsley, dill, or chives sprinkled on top add a burst of color and aroma that lifts the casserole to the next level. If you enjoy a little crunch, a handful of toasted pine nuts makes a fantastic garnish too.
Side Dishes
This Baked Zucchini Spinach and Feta Casserole pairs beautifully with crisp green salads, roasted garlic potatoes, or even a warm, crusty loaf of artisan bread to scoop up every last bite. For a heartier meal, grilled chicken or fish make excellent companions.
Creative Ways to Present
Serve the casserole in individual ramekins for an elegant dinner party presentation or layer it with thin slices of tomato on top before baking to add a pop of color and juicy flavor. Another fun idea is to sprinkle extra feta halfway through baking for a gooey, melty cheese topping.
Make Ahead and Storage
Storing Leftovers
After enjoying this casserole, wrap any leftovers tightly with plastic wrap or place them in an airtight container. Stored in the refrigerator, your Baked Zucchini Spinach and Feta Casserole will stay fresh and tasty for up to three days, making it a perfect next-day meal.
Freezing
For longer storage, this casserole freezes beautifully. Portion it into airtight containers or freezer-safe bags and freeze for up to two months. Thaw overnight in the fridge before reheating to maintain its texture and flavor.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through to keep that delightful golden crust intact. Microwaving works too, but reheating gently in the oven preserves the casserole’s texture better, ensuring every bite is as delightful as when freshly baked.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just make sure to thaw it completely and squeeze out as much excess water as possible before adding it to the casserole. This will prevent the dish from becoming too watery.
Is this casserole suitable for vegetarians?

Can I substitute feta cheese with another cheese?
Feta gives this casserole its signature tangy flavor, but you can use goat cheese or even ricotta for a creamier texture. Just keep in mind the flavor will shift slightly depending on the cheese you choose.
What if I want to add more veggies?
Feel free to add chopped bell peppers, mushrooms, or even some grated carrots for extra color and nutrition. Just be mindful of moisture content; draining any watery vegetables will help maintain the casserole’s texture.
