Sheet-Pan Chicken with Tomatoes and Mozzarella

This easy sheet-pan chicken with tomatoes and mozzarella is a vibrant, high-protein dinner that requires minimal effort. By roasting succulent chicken cutlets alongside sweet baby tomatoes, garlic and fragrant dried oregano, you create a delicious savoury sauce directly on the baking tray. The addition of melted mozzarella adds a creamy richness that perfectly balances the acidity of the tomatoes and the subtle heat from the sliced peperoncini.

Ideal for busy weeknights, this Mediterranean-inspired dish is both healthy and satisfying. The chicken stays tender thanks to the quick roasting time, while the red onion provides a fresh, crunchy finish. Serve this traybake on its own for a light low-carb meal, or pair it with some crusty sourdough bread or a side of fluffy couscous to soak up the juices.

Ingredients for Sheet-Pan Chicken with Tomatoes and Mozzarella

  • 1700ml grape tomatoes, halved

  • 60ml extra-virgin olive oil

  • 1 teaspoon white balsamic or white wine vinegar

  • 2 garlic cloves, thinly sliced

  • 1 tablespoon plus 1 teaspoon dried oregano

  • 2 teaspoons kosher salt, divided

  • 4 pieces thin-sliced skinless, boneless chicken breast, or 2 skinless, boneless chicken breasts (about 450g .)

  • 1 teaspoon freshly ground black pepper

  • 275g fresh mozzarella, thinly sliced into rounds

  • 1/2 small red onion, thinly sliced into rounds

  • 80g peperoncini (about 90g ), thinly sliced crosswise

Preheat oven to 204°C. Toss tomatoes, oil, vinegar, garlic, 1 tablespoon oregano, and 1 teaspoon salt on an 18x13" rimmed baking sheet.

If using skinless, boneless chicken breasts, slice them into 4 cutlets: Holding knife blade parallel to board, cut breast in half, slicing along a long side, to make 2 pieces.

Season chicken on all sides with pepper and remaining 1 teaspoon salt and 1 teaspoon oregano. Nestle chicken into tomato mixture. Roast until chicken is almost fully cooked through and tomatoes are starting to burst, 8–10 minutes. Arrange mozzarella rounds over chicken and tomatoes. Return to oven and roast until cheese is melted and chicken is fully cooked through, 2–4 minutes. Top with onion and peperoncini.
