- 1/4 cup feta cheese, crumbled
- 1/4 cup Parmesan cheese, grated
- 1/4 cup panko breadcrumbs
- 2 egg whites
- 1/2 teaspoon salt
- 2 teaspoons garlic powder
- 1/2 teaspoon black pepper
- 1 teaspoon dried basil
- 9×13-inch casserole dish
- Large skillet
- Mixing bowls
- Measuring cups and spoons
- Spatula or wooden spoon
1. Preheat the Oven
Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch casserole dish to prevent sticking.
2. Sauté the Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced zucchini, yellow squash, and spinach, and cook for about 5 minutes, or until the vegetables are tender. Drain any excess liquid to avoid a watery casserole.
3. Combine the Ingredients
In a large mixing bowl, combine the sautéed vegetables with:
- Feta and Parmesan cheese for a rich, salty bite.
- Panko breadcrumbs to add a subtle crunch.
- Egg whites to bind everything together.
- Salt, garlic powder, black pepper, and dried basil for seasoning. Mix well until evenly combined.
4. Assemble & Bake
Transfer the mixture into the prepared casserole dish. Spread evenly and press down lightly. Bake for 30-40 minutes, or until the top is golden brown.
5. Serve & Enjoy
Let the casserole cool slightly before serving. Enjoy it warm as a side dish or light meal!
Recipe Swaps & Additions

Shortcuts & Time-Savers

Storing Leftovers
- Store in an airtight container in the fridge for up to 4 days.
- Freeze for up to 3 months; thaw in the refrigerator before reheating.
Reheating
- Microwave: Heat in 30-second intervals until warm.

Pairing Ideas
- Main Course: Serve with grilled chicken, fish, or tofu for a complete meal.
- Side Dish: Pair with roasted potatoes, quinoa, or a fresh salad.

Can I Make This Ahead of Time?
Yes! You can assemble the casserole a day in advance and bake it just before serving.
Can I Use Different Cheeses?
Absolutely! Goat cheese, ricotta, or shredded mozzarella work great in place of feta.
What If I Don’t Have Panko Breadcrumbs?
You can use regular breadcrumbs, crushed crackers, or even finely chopped nuts for a unique twist.
How Do I Prevent a Soggy Casserole?
Make sure to drain excess liquid from the vegetables after sautéing, and avoid overloading the dish with too much cheese.
