Delicious Chicken with Pesto

Tender chicken breasts surrounded by soft, popped tomatoes bathing in herby pesto and covered with melted mozzarella makes dinner magic without much work. This single-pan creation brings bright summery tastes all year with the right mix of tangy tomatoes, fragrant basil sauce, and stretchy cheese that turns basic chicken into something you'll crave.

When I first cooked this for my family, amazing smells filled our kitchen and everyone showed up before I even yelled that dinner was ready. My teenage boy, who barely ever says nice things about food, wanted to know if we could eat it again tomorrow. When those roasted tomatoes break down into their own sauce, mixed with the smell of pesto and that bubbly cheese, it makes something almost magical that goes beyond its basic parts.

Key Ingredients

• Cherry tomatoes: Pick ripe, solid ones with bright colors to get the best taste since they're the base of your sauce
• White wine vinegar: Gives the needed tang to cut through the rich pesto and cheese
• Butter: Makes the sauce smooth while adding a deep flavor layer
• Basil pesto: Homemade has the strongest flavor but good store options work great too
• Fresh garlic: Chop it right before using for zingy flavors you can't get from pre-chopped stuff
• Fresh basil: Gives fresh, herby notes that lift the whole dish
• Mozzarella cheese: Grate it yourself for smoother melting than packaged shreds

Through trying different things, I found that using mixed-color cherry tomatoes not only looks pretty but creates little pockets of different flavors in the sauce. My garden grows tons of basil in summer, so I can make fresh pesto, but I always keep good jarred kinds around for winter cooking when fresh herbs cost more.

Flawless Cooking Method

Mix the flavor base:

Put olive oil, white wine vinegar, chopped garlic, salt, pepper, Italian herbs, and red pepper flakes in a plastic bag. Shake it hard until it's all mixed up.

Prep the chicken:

Put chicken breasts in the bag, close it tight, then gently squeeze to cover all pieces with the mixture.

Let it sit:

Let chicken soak for 15 minutes if you're in a hurry, or up to 2 hours if you want deeper flavor.

Get the dish ready:

Put butter in your baking dish and stick it in the oven while it heats up so the butter melts without getting brown.

Make the sauce starter:

Add cut cherry tomatoes, white wine vinegar, pesto, chopped garlic, fresh basil, salt, pepper, and onion powder to the melted butter. Stir gently to mix everything together.

Add the chicken:

Take chicken from the bag, let extra liquid drip off, then place the pieces among the tomato mix with a little space between them.

Cook it through:

Put the open dish in the hot oven until chicken reaches the right temp and tomatoes start getting soft and saucy.

Top it off:

Sprinkle lots of shredded mozzarella over the chicken at the end, then broil quickly until cheese gets bubbly with light gold spots.

My Italian grandma taught me that giving the tomato mix a stir halfway through cooking helps spread the flavors better. She always did this little step, saying it made all the difference. After making this dish both ways for years, I know she was right. That quick stir really does make a more even sauce with better taste throughout.

Tasty Side Pairings

This dish goes great with pasta. Firm spaghetti or linguine twists nicely with the tomato pesto sauce. Crusty bread works beautifully too—slices of artisan sourdough or ciabatta with olive oil soak up every bit of the yummy sauce. Cooked asparagus, quick-fried zucchini, or a simple green salad with lemon dressing adds fresh contrast to the rich main dish.

Tasty Twists

You can swap the meat to suit different tastes. Try boneless chicken thighs for juicier results, or go with Italian sausages for stronger flavor. Play with different cheeses—swap mozzarella for fontina to get a nuttier taste, or try provolone for something stronger. Add more veggies to expand the dish—toss in spinach during the last five minutes or add sliced bell peppers with the tomatoes for sweet, colorful bites.

Smart Leftover Tips

Keep leftovers fresh in the fridge—store them in a sealed container with sauce covering the chicken so it won't dry out. Freezing works great too—divide cooled leftovers into freezer containers and freeze for up to two months. Warm it up the right way—thaw in the fridge overnight, then heat it covered in a 325°F oven just until it's warm again.

Pin it

I first made this dish one summer when my garden gave me way too many tomatoes and basil to eat fresh. Putting them together seemed natural, but what happened in the oven was way better than I expected. Years later, we still make this dish often for family dinners and when friends come over. Its simple beauty always gets compliments, showing again that good ingredients handled simply often make the most unforgettable meals.

Frequently Asked Questions

→ Can I use chicken thighs instead of chicken breasts for this recipe?

Yes, you can! Boneless, skinless thighs work great in this dish and many folks like them better because they're juicier and more flavorful. If you go with thighs, you might need to cook them a bit differently—they take about the same time but won't dry out if you cook them a little longer. Try to pick thighs that are all about the same size so they cook evenly. Make sure they reach 165°F inside when they're done. Thighs naturally have more flavor, which goes really well with the pesto in this dish.

→ What kind of pesto works best for this chicken recipe?

Regular basil pesto (made with pine nuts, Parmesan, garlic, and olive oil) is perfect, but you've got lots of choices. The refrigerated store-bought kind usually tastes better than the jar versions that don't need refrigeration, but either will do the job. If you're making your own, classic basil pesto is great, but you can try sun-dried tomato pesto for richer flavor, or mix in some spinach for added nutrients. If you can't eat nuts, look for pesto made with sunflower seeds. Need a dairy-free option? Find one without Parmesan or make your own using nutritional yeast instead. Whatever type you pick, just make sure it's not too oily or too thick for the best sauce.

→ How do I prevent the chicken from becoming dry when baking?

Getting juicy baked chicken in this dish comes down to a few easy tricks. First, that quick marinade helps protect the outside of the chicken. Second, don't overcook it—use a meat thermometer and take the chicken out when it hits 155-160°F, as it'll keep cooking to the safe 165°F while resting and when you're melting the cheese under the broiler. The pesto and tomatoes also add moisture while cooking. If your chicken breasts are really thick, try slicing them into thinner pieces or pounding them to about ¾ inch thick. And don't forget to let everything sit for 5 minutes after cooking so the juices can settle back into the meat.

→ Can I prepare this dish ahead of time?

This pesto chicken gives you plenty of make-ahead options. You can let the chicken sit in the marinade for up to 8 hours in the fridge instead of just 10-15 minutes—this actually makes it taste even better. Or you can put the whole dish together right up to the baking part, cover it, and keep it in the fridge for up to 24 hours. Just let it warm up on the counter for about 20 minutes before you bake it. For meal prep, you can cook everything, divide it into containers without adding the cheese, and keep it in the fridge for up to 3 days. Then just reheat and add fresh cheese when you're ready to eat. The cooked dish doesn't freeze well because of the tomatoes and cheese, but you can freeze the raw marinated chicken for up to 3 months, then thaw it and follow the rest of the steps.

→ What can I substitute for white wine vinegar?

If you don't have white wine vinegar, you've got several good options that'll still give you that nice tangy kick. Red wine vinegar works just as well and you can use the same amount. Apple cider vinegar is good too, though it has a slight fruity taste. For something milder, try rice vinegar, but you might want to use less sugar in your pesto since rice vinegar is naturally sweeter. In a hurry? Fresh lemon juice makes a great substitute—just use the same amount as you would vinegar. You could also mix 1½ tablespoons of white wine with ½ tablespoon of any regular vinegar to get close to the white wine vinegar flavor.

→ What are the best side dishes to serve with this pesto baked chicken?

This pesto chicken goes well with lots of different sides. For an Italian-style meal, serve it over pasta tossed with a bit of olive oil or with crusty bread to soak up all the yummy sauce. Want something lighter? Try it with roasted veggies like asparagus, zucchini, or bell peppers—you can even cook them in the oven at the same time on another rack. Cauliflower rice or a simple green salad with lemon dressing makes it a good low-carb option. For something heartier, creamy polenta or garlic mashed potatoes taste great with the pesto flavors. For a complete Mediterranean-style meal, pair it with herb-seasoned orzo or a simple cucumber and tomato salad.
