Ingredients for Baked Zucchini, Spinach, and Feta Casserole

2 tablespoons olive oil: For sautéing the vegetables.
3 cups baby spinach: Fresh spinach adds a pop of color and nutrients.
2 small zucchini, diced: Zucchini is the base of this casserole, providing a mild, slightly sweet flavor.
2 small yellow squash, diced (or substitute with zucchini): Yellow squash adds variety, but you can use all zucchini if preferred.
1/4 cup fat-free feta cheese crumbles: Feta adds a tangy, salty flavor without the extra calories.
1/4 cup low-fat grated Parmesan cheese: Parmesan adds a nutty, savory note.
1/4 cup whole-wheat panko breadcrumbs: For a crispy, golden topping.
2 egg whites: To bind the ingredients together.
1/2 teaspoon kosher salt: Enhances the flavors.
2 teaspoons garlic powder: Adds a savory, aromatic touch.
1/2 teaspoon ground black pepper: For a hint of spice.
1 teaspoon dried basil leaves: Adds a fresh, herby flavor.

Step-by-Step Instructions

Step 1: Preheat the Oven

Start by preheating your oven to 400°F (200°C). This ensures the casserole bakes evenly and develops a golden-brown crust.

Step 2: Prepare the Casserole Dish

Spray a 9 x 13 inch casserole dish with non-stick cooking spray. This prevents the casserole from sticking and makes cleanup a breeze.

Step 3: Sauté the Vegetables

In a large skillet, heat the 2 tablespoons of olive oil over medium heat. Once the oil is hot, add the 3 cups of baby spinach, diced zucchini, and diced yellow squash. Cook for about 5 minutes, stirring occasionally, until the spinach is wilted and the squash is tender. Drain any excess liquid and transfer the mixture to a large mixing bowl.

Step 4: Combine the Ingredients

To the mixing bowl with the sautéed vegetables, add the feta cheese, Parmesan cheese, whole-wheat panko breadcrumbs, egg whites, kosher salt, garlic powder, black pepper, and dried basil. Mix everything together until well combined.

Step 5: Assemble the Casserole

Spread the mixture evenly in the prepared casserole dish. Make sure the top is smooth for an even bake.

Step 6: Bake the Casserole

Place the casserole in the preheated oven and bake for 30 to 40 minutes, or until the top is golden brown and the casserole is set.

Step 7: Let It Cool

Once baked, remove the casserole from the oven and let it cool for 5-10 minutes before serving. This allows the flavors to meld and makes it easier to slice.

This versatile vegetable is not only delicious but also packed with nutrients that make it a fantastic addition to any meal. Zucchini is low in calories, with just about 17 calories per cup, making it an excellent choice for those looking to maintain or lose weight. Despite its low calorie count, zucchini is rich in essential vitamins and minerals, including vitamin A, vitamin C, and potassium. These nutrients play a crucial role in supporting overall health, from boosting the immune system to promoting healthy skin and vision.

One of the standout features of zucchini is its high water content, which makes it incredibly hydrating. This is especially beneficial during the warmer months when staying hydrated is essential. Additionally, zucchini is a good source of dietary fiber, which aids in digestion and helps maintain a healthy gut. Fiber also contributes to a feeling of fullness, which can prevent overeating and support weight management goals. The fiber in zucchini, combined with its low calorie count, makes it a perfect ingredient for those looking to create healthy, satisfying meals.

Another benefit of zucchini is its versatility in cooking. It has a mild flavor that pairs well with a variety of ingredients, making it a great base for dishes like this casserole.

These vitamins work together to support a healthy immune system, keeping you feeling your best.

Another benefit of spinach is its high antioxidant content, particularly lutein and zeaxanthin. These antioxidants are known for their role in promoting eye health and reducing the risk of age-related macular degeneration.
