Description
Sheet Pan Mediterranean Chicken and Zucchini is a bright, herb-forward dinner of bite-sized chicken pieces, zucchini half-moons, halved cherry tomatoes, and red onion roasted together at 425°F and finished with melted mozzarella and Parmesan. Oregano, smoked paprika, and fresh garlic build a layered Mediterranean spice base that caramelizes in the oven while the cherry tomatoes burst into a natural pan sauce beneath the golden cheese topping.
Ingredients
1½ pounds boneless, skinless chicken breasts, cut into bite-sized pieces
2 tablespoons olive oil, divided
2 cloves garlic, minced
1 teaspoon dried oregano
1 teaspoon smoked paprika
Salt, to taste
Black pepper, to taste
2 medium zucchini, sliced into half-moons
1 pint cherry tomatoes, halved
1 small red onion, thinly sliced
1 cup shredded mozzarella cheese
¼ cup grated Parmesan cheese
Fresh parsley, chopped (for garnish)
Instructions
1. Preheat the oven to 425°F (220°C).
2. In a large bowl, toss the chicken pieces with 1 tablespoon olive oil, minced garlic, oregano, smoked paprika, salt, and black pepper until every piece is thoroughly and evenly coated.
3. In a second bowl, toss the zucchini half-moons, halved cherry tomatoes, and sliced red onion with the remaining 1 tablespoon olive oil and a pinch of salt and pepper.
4. Spread the seasoned chicken and the seasoned vegetables together in a single, even layer on a large sheet pan with no overlapping.
5. Roast for 20–25 minutes, stirring everything once at the halfway mark, until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender and the tomatoes have burst.
6. Remove the pan from the oven and sprinkle the shredded mozzarella and grated Parmesan evenly over the chicken and vegetables.
7. Return the sheet pan to the oven for 2–4 minutes, until the mozzarella is fully melted and the Parmesan develops light golden spots at the edges. Watch closely — cheese burns quickly at this temperature.
8. Garnish with freshly chopped parsley and serve immediately.
Notes
The cherry tomatoes burst and release their juices during roasting — this is the natural sauce of the dish, not a problem. Spoon those pooled tomato juices over each serving when plating; they carry the concentrated flavor of roasted tomatoes, garlic, and oregano and are the most important finishing step.
Watch the cheese finish with full attention — mozzarella at 425°F transitions from melted to golden to scorched in under 60 seconds; pull the pan the moment the cheese turns spotty and golden at the edges.
Use fresh minced garlic rather than garlic powder — minced garlic blooms in the olive oil during roasting and produces a significantly more aromatic result than powder.
Stir at the halfway mark without fail — bite-sized chicken pieces and halved cherry tomatoes need repositioning for even browning and to prevent the tomatoes from sticking to the parchment.
Serve immediately — mozzarella loses its stretch quickly as it cools and the tomato pan sauce pools and thickens; this dish is at its best the moment it leaves the oven.
| Storage method | Duration | Reheating instructions |
|---|---|---|
| Refrigerator | Up to 4 days | Reheat at 375°F for 10–12 minutes; add a small amount of fresh mozzarella and return for 2 minutes to restore the cheese topping |
| Freezer (without cheese) | Up to 2 months | Freeze chicken and vegetables without the cheese topping. Thaw overnight, reheat at 375°F for 12 minutes, then add fresh cheese and finish for 2–4 minutes. |
| Microwave | Use within 4 days | Reheat in 60-second intervals on medium power — cheese softens but loses stretch; oven reheating is strongly preferred for this dish |
