Step-by-Step Instructions

[INSERT PROCESS IMAGE HERE]

1. Preheat your oven to 400°F. Lightly grease a round or medium-sized baking dish with cooking spray or a little olive oil.
2. Place the sliced zucchini and onion in a large mixing bowl. Add 1 tablespoon of olive oil, half of the Italian seasoning, and a small pinch of salt and pepper. Toss until evenly coated.
3. In a separate bowl, combine the chicken pieces with the remaining 1 tablespoon olive oil, the remaining Italian seasoning, paprika, garlic, 1/2 teaspoon kosher salt, black pepper, and red pepper flakes if using. Toss well so the chicken is evenly seasoned.
4. Spread the zucchini and onion mixture in an even layer in the prepared baking dish.
5. Arrange the seasoned chicken pieces over the zucchini layer so they are distributed evenly.
6. Sprinkle the mozzarella and Parmesan over the top of the chicken and zucchini.
7. Bake uncovered for 30 to 35 minutes, or until the chicken is cooked through and reaches a safe internal temperature of 165°F, the zucchini is tender, and the cheese is melted and golden in spots.
8. If you want a little more browning, broil for 1 to 2 minutes at the end, watching closely so the cheese doesn’t burn.
9. Remove the dish from the oven and let it rest for 5 minutes. Finish with chopped parsley or basil before serving.

Storage & Make-Ahead Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or in a 350°F oven until hot throughout. For food safety, make sure leftovers are reheated thoroughly before serving.

If you want to prep ahead, you can slice the zucchini, onion, and chicken earlier in the day and keep them refrigerated separately. You can also assemble the entire dish a few hours ahead, cover it, and refrigerate until ready to bake. If baking straight from the fridge, you may need to add a few extra minutes to the cooking time.

I don’t usually recommend freezing this one if texture is important to you, because zucchini can become quite soft after thawing. It will still taste good, but the texture won’t be quite the same as freshly baked.

FAQ

1. Can I make this Chicken Zucchini Bake ahead of time?

Yes. You can assemble it several hours ahead, cover it, and refrigerate it until you’re ready to bake. Just add a little extra baking time if the dish is cold from the refrigerator.

2. How do I keep zucchini from making the bake watery?

Use medium-thick slices, avoid overcrowding the dish, and if your zucchini seem extra watery, lightly salt them first and pat them dry before assembling.

3. Can I use chicken thighs instead of chicken breasts?

Absolutely. Boneless skinless chicken thighs work very well here and stay juicy. Just make sure they are cut into even pieces and cooked to a safe internal temperature of 165°F.

4. What cheese works best in this recipe?

Mozzarella and Parmesan give this bake a classic melty, savory flavor, but provolone, Monterey Jack, or an Italian cheese blend are all great options too.

5. What can I serve with this recipe?

It’s great with rice, pasta, roasted potatoes, garlic bread, or a simple salad. If you want to keep it low-carb, it’s filling enough to serve on its own.

Notes

Cut the chicken into even pieces for consistent cooking. Use 1/4-inch zucchini slices so they stay tender without turning mushy. If the zucchini seems watery, lightly salt and pat dry before baking. Store leftovers refrigerated for up to 3 days.
