Step‑by‑Step Instructions for Baked Zucchini Spinach and Feta Casserole
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and prepare a baking dish by greasing it with nonstick cooking spray or a light drizzle of olive oil. This ensures that your Baked Zucchini Spinach and Feta Casserole won’t stick during baking, allowing for easy serving and cleanup. Gather all ingredients to streamline your cooking process and enjoy the flow of creating this comforting dish.
Step 2: Slice the Vegetables
Wash the zucchinis thoroughly under cool water, then slice them into thin rounds, about 1/4 inch thick. In a large mixing bowl, combine the sliced zucchini with fresh spinach leaves, as this vibrant duo will form the flavorful base of your casserole. Aim for an even mix of vegetables to ensure every bite of your casserole is loaded with taste and nutrition.
Step 3: Whisk the Egg Mixture
In a separate medium-sized bowl, crack the eggs and whisk them together until fully combined. Add crumbled feta cheese, garlic powder, salt, pepper, and olive oil to the eggs, then blend until you have a smooth mixture. This egg mixture will bind the ingredients, enhancing the texture and flavor of the Baked Zucchini Spinach and Feta Casserole, so make sure it’s well-mixed and creamy.
Step 4: Combine Mixtures
Pour the egg and feta mixture over the zucchini and spinach in the mixing bowl. Gently stir the ingredients together until the zucchini and spinach are fully coated with the egg mixture. This step is crucial for the even distribution of flavors throughout the casserole, making it a delightful vegetarian dish that everyone will enjoy.
Step 5: Transfer to Baking Dish
Carefully transfer the combined mixture into the prepared baking dish, spreading it out evenly with a spatula or spoon. Take a moment to ensure the layers are even and there are no large gaps. This will help your Baked Zucchini Spinach and Feta Casserole cook uniformly, giving you that lovely golden-brown crust that everyone loves.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake the casserole for 30 to 35 minutes, or until the top is golden brown and slightly set. Keep an eye on it during the last few minutes of baking; it should be bubbling around the edges as the creamy interior firms up. The delightful aroma will fill your kitchen, promising a delicious meal ahead.
Step 7: Cool and Serve
Once baked to perfection, carefully remove the Baked Zucchini Spinach and Feta Casserole from the oven. Allow it to cool slightly in the dish for about 5 to 10 minutes before slicing. This brief cooling period lets the casserole firm up a bit, making it easier to serve. Enjoy this comforting dish warm and let the flavors shine through!
