How to Make Baked Zucchini Spinach and Feta Casserole
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). While the oven warms up, grease your baking dish with a light coating of olive oil or non-stick spray to prevent sticking and help create that perfect golden crust on your casserole.
Step 2: Slice and Combine the Vegetables
Thinly slice your zucchinis into rounds—they cook faster and meld better with the spinach this way. Toss them together with the fresh spinach in a large bowl, mixing well so you get an even distribution of those vibrant greens throughout the casserole.
Step 3: Whisk the Egg Mixture
In another bowl, whisk your eggs until smooth, then stir in the crumbled feta cheese, garlic powder, salt, pepper, and olive oil. This mixture is the creamy, flavorful glue that will hold your vegetables together and make every bite rich and satisfying.
Step 4: Combine and Transfer
Pour your egg and cheese mixture over the zucchini-spinach blend. Stir gently but thoroughly so that every piece of vegetable is coated with this luscious mixture. Then, transfer everything into your prepared baking dish and spread it out evenly.
Step 5: Bake to Perfection
Slide your dish into the oven and bake for about 30 to 35 minutes until the top turns a lovely golden brown. The casserole should be set and slightly puffed up, with a delightful crust that invites you to dig in.
How to Serve Baked Zucchini Spinach and Feta Casserole

Garnishes
A sprinkle of fresh herbs like chopped dill or parsley brightens up the Baked Zucchini Spinach and Feta Casserole beautifully. If you want a bit of crunch, toasted pine nuts or a dusting of paprika can add an exciting finishing touch.
Side Dishes
This casserole pairs wonderfully with a crisp green salad dressed lightly with lemon vinaigrette or a side of warm, crusty bread to soak up every bit of its creamy flavor. For a more substantial meal, consider serving it alongside roasted chicken or grilled fish.
Creative Ways to Present
For a family dinner, serve the casserole straight from the baking dish to keep it warm and comforting. If you’re aiming to impress guests, use individual ramekins or mini cast-iron skillets to create personal portions. A drizzle of extra virgin olive oil on top before serving adds an inviting shimmer and richness.
Make Ahead and Storage
Storing Leftovers
Once cooled, place any leftover Baked Zucchini Spinach and Feta Casserole in an airtight container and keep it in the refrigerator. It stays fresh and flavorful for up to 3 days, making it an excellent option for quick lunches or easy dinners.
Freezing
This casserole freezes beautifully. Wrap individual portions tightly in plastic wrap and foil or use freezer-safe containers. It can be stored in the freezer for up to 2 months. When ready to enjoy, thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in a preheated oven at 350°F (175°C) for about 15-20 minutes until warmed through. For quicker options, microwave on medium power, but be careful not to overcook to preserve the great texture and flavor.
FAQs
Can I use frozen spinach instead of fresh?
Absolutely! Just be sure to thaw and thoroughly squeeze out excess moisture from frozen spinach before mixing it in to avoid a soggy casserole.
Is there a substitute for feta cheese?
You can swap feta with goat cheese or ricotta for a different flavor, but feta’s salty tang is key to the character of this casserole.
Can this recipe be made vegan?
To make it vegan, replace eggs with flax eggs or a commercial egg replacer, and use a plant-based feta alternative, but be aware that texture and flavor will vary.
What should I do if the casserole is too watery?
Make sure to slice your zucchini thinly and avoid excess moisture by lightly salting and letting it sit before combining—then gently pat it dry. This keeps the casserole from becoming soggy.
Can I add other vegetables?
Definitely! Chopped bell peppers, mushrooms, or onions make great additions, adding more flavor and texture to the Baked Zucchini Spinach and Feta Casserole.
