How To Make Chicken Zucchini Bake
This summary covers the key steps. Follow the recipe card below for the exact measurements, times, and full instructions.
Prep Oven, Baking Dish, and Marinade
1. Preheat the oven to 425°F (220°C). Lightly spray or grease an 8×8-inch baking dish.
2. In a large bowl, combine garlic powder, paprika, dried oregano, cumin, salt, black pepper, and olive oil. Stir until a uniform marinade forms.
Marinate the Chicken and Veggies
3. Add the cut chicken, chopped onion, and chopped zucchini to the marinade. Toss thoroughly to coat all pieces.
4. For best flavor, cover and refrigerate to marinate up to 24 hours. If short on time, bake immediately—this dish is flavorful even without an overnight marinade.
Bake and Serve
5. Transfer the marinated chicken and vegetables to the prepared baking dish and spread into an even layer.
6. Bake uncovered at 425°F (220°C) for about 30 minutes, or until the chicken registers 165°F (74°C) and the vegetables are tender and slightly caramelized.
7. Serve hot with fluffy buttered rice, quinoa, or a green salad. Enjoy!
Recipe Tip
Prep this dish the night before and let it marinate overnight so flavors deepen and dinner cooks quickly the next evening. Marinating also helps keep chicken juicy and infuses the zucchini with seasoning.
Make It A Meal
This bake pairs well with white or brown rice, quinoa, or a simple side salad. Add crusty bread to soak up juices, or serve with a side of roasted potatoes. For a lighter option, skip the grains and serve over mixed greens.
Storage
SERVE: Best served hot, freshly baked, alongside rice or a grain of your choice.
STORE: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
FREEZE: Cool completely before transferring to a freezer-safe container. Freeze for 2–3 months. Note that zucchini softens when frozen and reheated, so texture may change slightly.
DEFROST: Thaw frozen portions in the refrigerator overnight or at room temperature for a few hours before reheating.
REHEAT: Reheat in a preheated 350°F (175°C) oven for 15–20 minutes or until heated through. Microwave reheating is faster but may affect texture.
Recipe FAQs
