Ingredients

2 cups cooked shredded chicken (about 2 boneless, skinless breasts)
2 medium zucchinis, diced (about 1 cup)
1 cup shredded part‑skim mozzarella cheese
1 cup shredded part‑skim cheddar cheese
1 cup low‑fat plain Greek yogurt
1/2 cup low‑fat milk
2 large eggs, beaten
1/2 cup grated Parmesan cheese

How to Make Chicken Zucchini Bake Casserole

Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with a light spray of olive oil.
Sauté the zucchini. In a skillet, heat 1 tablespoon olive oil over medium heat. Add the diced zucchini and minced garlic, sautéing until the zucchini is just tender, about 4–5 minutes. Season with a pinch of salt and pepper. Set aside.
Mix the base. In a large bowl, combine the shredded chicken, sautéed zucchini, Greek yogurt, milk, beaten eggs, mozzarella, cheddar, Parmesan, Italian seasoning, salt, and pepper. Stir until everything is evenly coated.
Transfer to the dish. Pour the mixture into the prepared baking dish, spreading it out evenly.
Top it off. In a small bowl, mix the panko breadcrumbs with the remaining tablespoon of olive oil. Sprinkle the breadcrumb mixture over the casserole. Finish with a light dusting of grated Parmesan.
Bake. Place in the oven and bake for 25–30 minutes, or until the top is golden brown and the casserole is set. A toothpick inserted in the center should come out clean.
Rest and serve. Let the casserole rest for 5 minutes before slicing. Garnish with chopped parsley for a fresh pop of color.

Tips for Best Results

Use leftover rotisserie chicken for a time‑saving shortcut.
For extra moisture, add a splash of low‑fat milk to the yogurt mixture.
If you like a crisp top, broil for the last 2 minutes—watch closely to avoid burning.
To keep the casserole from drying out, cover loosely with foil during the first 15 minutes of baking.

Variations

Spicy Kick: Add 1/2 teaspoon crushed red pepper flakes to the base mixture.
Herb Boost: Stir in 1 tablespoon chopped fresh basil or oregano.
Cheese Swap: Replace mozzarella with provolone for a richer flavor.
Veggie Mix‑in: Toss in diced bell peppers or spinach for extra color and nutrition.

Storage

Cool the casserole completely, then cover tightly and refrigerate for up to 3 days. Reheat individual portions in the microwave for 2–3 minutes or in a preheated oven at 350°F (175°C) for 15 minutes. For leftovers, you can also freeze the casserole—just thaw overnight in the fridge and reheat as above.
