This Chicken Pesto Bake is one of those recipes I come back to again and again because it delivers big, bold Italian-inspired flavour with barely any effort. Thin chicken cutlets get a generous spread of basil pesto, then they’re baked until just cooked through before being topped with ripe tomato slices, creamy fresh mozzarella, and a shower of sharp Pecorino Romano.
The whole thing goes back in the oven just long enough for the cheese to melt into a bubbly, golden layer that pulls apart in the most satisfying way. From start to finish, you’re looking at about 35 minutes — and most of that is hands-off oven time.
What I love most is how flexible it is. Swap the mozzarella for Monterey Jack or even a tangy chèvre, use store-bought or homemade pesto, and pair it with whatever sides you have on hand. It’s the kind of recipe that feels special without requiring a single complicated technique.
If you need a dinner that impresses but doesn’t stress you out, this cheesy chicken pesto bake is exactly what you’re looking for.
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.

What Makes This Chicken Pesto Bake Special
Plenty of baked chicken recipes exist, but this one stands apart for a few key reasons. First, butterflying the chicken breasts into thin cutlets means they cook evenly and quickly — no dry edges with a raw centre. Second, baking the pesto directly onto the chicken rather than just spooning it on top allows the basil and garlic flavours to penetrate the meat during cooking.
The two-stage baking method is what really makes this work. The chicken gets its initial 15 minutes to cook through, then the fresh tomato and mozzarella go on for a brief 3-5 minute melt. This keeps the tomatoes from turning to mush and ensures the mozzarella stays soft and stretchy instead of drying out and turning tough. The final hit of salty Pecorino Romano on top adds a sharp contrast to the creamy mozzarella — it’s a small detail that elevates the whole dish.
Tips for Best Results
- Pound the cutlets evenly: After butterflying, use a meat mallet or rolling pin to gently pound each cutlet to an even ½-inch / 1.25cm thickness. This is the single most important step for even cooking.
- Pat the chicken completely dry: Moisture on the surface creates steam and prevents the pesto from adhering properly. Take an extra 30 seconds with paper towels — it makes a real difference.
- Use quality pesto: Since pesto is one of only six ingredients, its quality matters enormously. A bright, basil-forward pesto (whether store-bought or homemade) will shine here. Avoid anything that tastes predominantly of oil or has gone dark green.
- Slice the tomato thinly: Thick tomato slices won’t warm through in the short second bake. Aim for ¼-inch rounds so they soften slightly without releasing too much liquid onto the chicken.
- Don’t skip the rest: Let the finished bake sit for 2-3 minutes before cutting. This allows the juices to redistribute so your cutting board doesn’t flood.
Substitutions and Variations
- Cheese swaps: Monterey Jack melts beautifully and adds a mild, buttery note. Provolone brings a slightly smoky edge. Crumbled chèvre (goat cheese) won’t melt the same way but adds a tangy creaminess that pairs wonderfully with pesto. For a sharper finish, use Parmigiano-Reggiano instead of Pecorino Romano.
- Pesto variations: Sun-dried tomato pesto creates a richer, more intensely savoury version. Roasted red pepper pesto adds a subtle sweetness. Kale-walnut pesto works well in autumn and winter months.
- Add vegetables: Layer thinly sliced zucchini or roasted red peppers between the chicken and the cheese for added colour and nutrients.
- Protein swap: Turkey breast cutlets, boneless pork chops (pounded thin), or thick-cut firm tofu all work with the same method — adjust baking time based on the protein’s thickness.
- Make it spicy: Add a pinch of red pepper flakes over the pesto before baking, or drizzle with a touch of hot honey after it comes out of the oven.
Storage and Reheating
Leftover Chicken Pesto Bake keeps well in an airtight container in the refrigerator for up to 3 days. To reheat, place the cutlets on a baking sheet and warm in a 350°F / 175°C oven for 10-12 minutes until heated through. This method keeps the chicken moist and the cheese melty. Avoid the microwave if possible — it tends to make the mozzarella rubbery and the chicken tough.
For meal prep, you can slice the reheated chicken and serve it cold over a salad with a drizzle of balsamic vinaigrette. It also makes an excellent sandwich filling — pile it into ciabatta with arugula and a squeeze of lemon.
To freeze, wrap individual cooled cutlets tightly in cling film and then aluminium foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven as described above.
What to Serve With This
- Simple green salad: Peppery arugula with shaved Parmesan, lemon juice, and olive oil is a classic pairing that cuts through the richness of the cheese.
- Roasted vegetables: Broccolini, asparagus, or cherry tomatoes roasted at the same 400°F temperature can go into the oven alongside the chicken for a one-oven meal.
- Garlic bread: A crusty baguette rubbed with garlic and toasted is perfect for soaking up any pesto and tomato juices on the plate.
- Pasta: Toss cooked penne or rigatoni with a little extra pesto and olive oil, then serve the chicken on top for a more substantial meal.
- Cauliflower mash: For a low-carb side, creamy cauliflower mash with a touch of Parmesan complements the Italian flavours beautifully.
Frequently Asked Questions
Can I use bone-in chicken thighs instead of chicken breasts?
Yes, but you’ll need to adjust the cooking time significantly. Bone-in, skin-on thighs need approximately 35-40 minutes at 400°F / 200°C before adding the tomato and cheese topping. The skin also won’t crisp up under the pesto, so spread the pesto under the skin for better flavour penetration.
How do I know when the chicken is fully cooked?
The most reliable method is using an instant-read thermometer. The chicken is done when it reaches an internal temperature of 165°F / 74°C at the thickest part. For thin cutlets like these, 15 minutes at 400°F is typically sufficient, but always verify with a thermometer rather than relying on colour alone.
Can I make this recipe ahead of time?
You can prepare the chicken through the seasoning and pesto-spreading step up to 12 hours in advance. Cover the baking sheet tightly with cling film and refrigerate. When ready to cook, let it sit at room temperature for 10 minutes, then bake as directed. Don’t add the tomato and cheese until after the initial bake.
Why did my mozzarella turn rubbery?
This usually happens when the cheese is in the oven too long. Fresh mozzarella only needs 3-5 minutes to melt — any longer and it starts to release moisture and toughen. Make sure you’re only adding the cheese for the final stage and watching it closely. Pull it out as soon as it’s melted and slightly bubbly.
Is store-bought pesto fine, or should I make my own?
Store-bought pesto works perfectly well here. Look for one that lists basil as the first ingredient and has a vibrant green colour. Refrigerated pesto from the deli section tends to taste fresher than jarred shelf-stable versions. That said, homemade pesto takes about 5 minutes in a food processor and will give you the brightest flavour.
Can I use pre-sliced or shredded mozzarella instead of a fresh mozzarella ball?
You can, but the result will be different. Low-moisture mozzarella (the kind sold pre-shredded or in blocks) melts into a stretchier, more pizza-like layer. Fresh mozzarella is creamier and softer when melted. Both taste great — it’s a texture preference. If using shredded, use about 1 cup / 115g.
A Little History: Chicken and Pesto
Pesto alla Genovese originated in Genoa, Italy, where it was traditionally made with a marble mortar and wooden pestle — the word pesto comes from the Italian pestare, meaning to pound or crush. For centuries, pesto was used almost exclusively on pasta, particularly trofie and trenette. The idea of pairing pesto with chicken is a distinctly Italian-American innovation that gained popularity in the 1990s as pesto moved from specialty ingredient to supermarket staple. Combining it with fresh mozzarella and tomato echoes the flavours of an insalata caprese, making this bake a delicious collision of Italian tradition and American convenience cooking.
