Description
One Pan Mediterranean Chicken and Zucchini Bake is a complete oven meal of bite-sized chicken, zucchini half-moons, cherry tomatoes, and red onion tossed together in a single bowl with garlic, oregano, basil, and smoked paprika, then baked at 375°F and finished with melted mozzarella and Parmesan.
Ingredients
2 boneless, skinless chicken breasts, cut into bite-sized pieces
2 tablespoons olive oil
2 cloves garlic, minced
1 teaspoon dried oregano
½ teaspoon dried basil
½ teaspoon smoked paprika
Salt, to taste
Black pepper, to taste
2 medium zucchini, sliced into half-moons
1 cup cherry tomatoes, halved
½ red onion, thinly sliced
½ cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
2 tablespoons fresh parsley, chopped (for garnish)
Instructions
1. Preheat the oven to 375°F (190°C).
2. Combine the chicken pieces, sliced zucchini, halved cherry tomatoes, sliced red onion, minced garlic, olive oil, dried oregano, dried basil, smoked paprika, salt, and black pepper in a large bowl. Toss until every piece of chicken and every vegetable is evenly and thoroughly coated.
3. Transfer the mixture to a lightly greased 9×13-inch baking dish or sheet pan and spread it into an even, single layer.
4. Bake for 30 minutes, undisturbed, until the tomatoes have burst, the vegetables are tender, and the chicken is nearly cooked through.
5. Remove the dish from the oven and sprinkle the shredded mozzarella and grated Parmesan evenly over the entire surface.
6. Return the dish to the oven and bake for an additional 5 minutes, until the cheese is fully melted and the chicken reaches an internal temperature of 165°F (74°C).
7. Scatter the chopped fresh parsley over the top.
8. Serve immediately on its own or with steamed rice, pasta, or crusty bread.
Notes
Do not increase the oven temperature to speed up the process — at 375°F the zucchini softens gently, the tomatoes burst into a natural sauce rather than drying out, and the cheese topping melts in exactly 5 minutes without over-browning; higher heat disrupts all three outcomes simultaneously.
Check the chicken temperature before adding the cheese — the final 5 minutes is calibrated for cheese melting, not additional chicken cooking; if the chicken reads below 160°F at the 30-minute mark, return the dish without cheese for 5 more minutes first.
A 9×13 baking dish produces a slightly saucier, more casserole-like result than a flat sheet pan because the walls contain the burst tomato juices — both work, but the baking dish version produces a richer, more cohesive pan sauce.
Spoon the burst tomato pan juices over each serving at plating — the concentrated liquid at the bottom of the dish is the natural sauce and carries more flavor than anything else in the pan.
Do not stir during the 30-minute initial bake — the gentle 375°F heat cooks everything evenly without scorching, and leaving it undisturbed allows the tomatoes to burst naturally and the flavors to meld without interruption.
| Storage method | Duration | Reheating instructions |
|---|---|---|
| Refrigerator | Up to 4 days | Reheat covered at 350°F for 12–15 minutes; uncover for the final 3 minutes to re-melt and restore the cheese topping |
| Freezer (without cheese) | Up to 2 months | Freeze without the cheese topping; thaw overnight, reheat covered at 350°F for 12 minutes, then add fresh mozzarella and Parmesan and bake uncovered for 5 minutes |
| Microwave | Use within 4 days | Reheat in 60-second intervals on medium power; add a small amount of fresh mozzarella and microwave for a final 30 seconds to restore the cheese layer |
