This is baked chicken breast topped with basil pesto, fresh mozzarella, ripe tomato, and grated Pecorino Romano — four cutlets, one baking dish, about 35 minutes. It works on a weeknight, and it scales cleanly if you need to feed more people without adding much work.
What makes this version work
Two things matter here. First, slicing the breasts into thinner cutlets — about ½ inch thick — means the chicken cooks through in 15 minutes without drying out. Thick, uneven chicken is the main reason this kind of bake goes wrong. Second, the tomato and mozzarella go on after the initial bake, not before. Adding them at the start releases too much liquid and turns the pesto layer watery. Pulling the dish out at the 15-minute mark, layering on the toppings, and returning it to the oven for a few minutes lets the mozzarella melt without the chicken overcooking. A meat thermometer takes the guesswork out entirely — pull it at 155°F / 68°C and carryover heat does the rest.
Substitutions that actually work
- Pesto: Store-bought works fine. Look for one with olive oil as the first ingredient, not sunflower oil. If you have homemade, use it — the flavour is noticeably better.
- Fresh mozzarella: Low-moisture block mozzarella melts more evenly and produces less liquid. It won’t have the same creamy texture, but it’s a practical swap if fresh isn’t available.
- Pecorino Romano: Parmesan is a direct swap. Pecorino is saltier and sharper, so if you use it, taste before adding extra salt to the chicken.
- Tomato: Roma or plum tomatoes have less water than beefsteak and hold their shape better on top of the chicken. Skip the garnish of extra fresh basil leaves on top — not worth the extra prep for what you get.
Common problems and fixes
- Chicken is dry by the time the cheese melts: Your cutlets were probably uneven. Use a sharp knife and take your time getting them to a consistent ½-inch thickness. An uneven cutlet means one end overcooks while the other catches up.
- Watery pesto layer: This usually means the tomatoes were added too early, or the mozzarella was very wet. Pat mozzarella slices dry with a paper towel before layering. If your tomatoes are very juicy, pat those dry too.
- Cheese isn’t browning: After the mozzarella melts, switch the oven to broil for 1–2 minutes. Watch it closely — it goes from melted to burnt faster than you’d expect.
- Cooking for a crowd: Use two baking dishes side by side rather than stacking or crowding cutlets. Overlapping chicken steams instead of baking, and the pesto layer gets soggy. Rotate the dishes halfway through if your oven has hot spots.
- Pesto slides off during baking: Make sure the chicken surface is dry before spreading the pesto. Any moisture on the surface stops it from adhering. Pat the cutlets thoroughly after seasoning.
Chicken Pesto Bake
Ingredients
- 2 pieces chicken breasts boneless, skinless; large, butterflied into 4 thin cutlets
- 1 pinch salt to taste
- 1 pinch ground black pepper to taste
- 4 tablespoons basil pesto about 1 tablespoon per cutlet
- 1 medium tomato ripe, sliced into ¼-inch rounds
- 1 ball fresh mozzarella cheese sliced into ¼-inch rounds
- 4 tablespoons Pecorino Romano (finely grated) or Parmesan
Instructions
- Preheat oven to 400°F / 200°C (205°C fan-forced).
- Pat chicken dry with paper towels (do not wash raw chicken — this can spread bacteria). Slice each chicken breast horizontally to create four thinner cutlets of even thickness, about ½ inch / 1.25 cm. Season both sides with salt and freshly ground black pepper.
- Place the chicken on a rimmed baking sheet. Spread 1 tablespoon of basil pesto evenly over each piece of chicken.
- Bake the chicken for 15 minutes or until the internal temperature reaches 155°F / 68°C (it will carry over to 165°F / 74°C while resting).
- Remove from oven and arrange sliced tomatoes on top of each cutlet. Layer fresh mozzarella slices over the tomatoes, then sprinkle the grated Pecorino Romano or Parmesan evenly over the top.
- Return to the oven and bake for an additional 3–5 minutes, or until the cheese is melted and bubbly.
- Let rest for 2–3 minutes, then serve over leafy greens as a salad or alongside your favourite roasted or steamed vegetables.

FAQ
Can I assemble this ahead of time and bake it later?
Yes — you can spread the pesto on the raw cutlets, cover the dish, and refrigerate for up to 8 hours before baking. Don’t add the tomato and mozzarella until the chicken comes out of the oven at the 15-minute mark, otherwise the toppings release liquid into the dish as it sits.
How do I know the chicken is actually cooked through without cutting into it?
Use an instant-read thermometer inserted into the thickest part of the cutlet — you’re looking for 155°F / 68°C before you add the toppings. The temperature will carry over to the safe 165°F / 74°C while the dish rests. Cutting into the chicken to check lets the juices run out and dries it out.
Can I double the recipe for a larger group?
Doubling is straightforward — use two standard baking dishes and keep the cutlets in a single layer. The bake time stays the same as long as the cutlets are the same thickness. If your oven runs unevenly, swap the dishes between racks halfway through.
