One-Pan Pesto Chicken and Vegetables

One-pan pesto chicken and vegetables is the dinner I reach for when I want something that tastes far more impressive than the ten minutes of prep it actually requires. Chicken, bell pepper, zucchini, cherry tomatoes, and red onion all tossed together in basil pesto and roasted on a single sheet pan at 425°F until the chicken is cooked through and the vegetables are tender with slightly caramelized edges. A scatter of melted mozzarella, fresh basil, and grated Parmesan at the end turns it from a simple sheet pan dinner into something that looks and tastes like it came together with far more effort.

The pesto is doing all the work here. Tossed with everything before it goes into the oven, it coats the chicken and vegetables in a garlicky, herby, slightly nutty flavor that intensifies as it roasts. There is no separate sauce, no additional seasoning blend, and no marinating time. One jar of pesto and a hot oven produce a dinner that tastes deeply flavored throughout.

Why You’ll Love This Recipe

One sheet pan and ten minutes of prep. Everything goes into one bowl, gets tossed, and spreads onto one pan. Cleanup is almost nothing.

The pesto seasons everything at once. There is no need for a separate spice blend or sauce since the pesto coats the chicken and every vegetable in the same bold, herby flavor.

The melted mozzarella at the end is the detail that makes this feel like a complete, finished dish rather than just roasted chicken and vegetables. It melts directly over everything in the last few minutes.

Ingredients Needed to Make One-Pan Pesto Chicken and Vegetables

The Chicken

Boneless skinless chicken breasts or thighs cut into 1-inch pieces cook through in the same 15 to 20 minutes as the vegetables. Thighs stay slightly juicier through the roast. Breasts are a leaner option that still works beautifully when cut to a consistent size.

The Vegetables

Bell pepper, zucchini, cherry tomatoes, and red onion all roast at the same rate when cut to similar sizes. Together they add color, sweetness, and a range of textures from the soft cherry tomatoes to the slightly firmer zucchini and pepper.

The Pesto and Toppings

Basil pesto is the single seasoning ingredient that coats everything before roasting. Shredded mozzarella melted over the top in the last few minutes adds a gooey, rich finish. Fresh basil and grated Parmesan added after baking finish the dish with brightness and a salty, nutty note.

How to Make One-Pan Pesto Chicken and Vegetables

Step 1: Prep and Toss

Preheat the oven to 425°F. Line a large sheet pan with parchment paper for easy cleanup. In a large bowl, combine the cut chicken, bell pepper, zucchini, cherry tomatoes, and red onion with the pesto, salt, and pepper. Toss until every piece is evenly coated in pesto.

Step 2: Spread and Roast

Spread the mixture into a single even layer on the prepared sheet pan, giving everything as much space as possible. Bake for 15 to 20 minutes until the chicken reaches an internal temperature of 165°F and the vegetables are tender with some color at the edges.

Step 3: Add the Mozzarella

If using mozzarella, scatter it evenly over the chicken and vegetables during the last 2 to 3 minutes of baking and let it melt completely.

Step 4: Garnish and Serve

Remove from the oven and garnish with fresh basil and grated Parmesan. Drizzle with additional pesto if desired. Serve immediately on its own or over rice, pasta, quinoa, or cauliflower rice.

Serving Suggestions

I like to serve this straight from the sheet pan with extra Parmesan and a drizzle of pesto at the table. Over a bed of pasta or rice it becomes a more filling dinner, with the pesto and roasted vegetable juices soaking into the base below. A simple green salad with a light vinaigrette alongside rounds the meal out without competing with the pesto flavor already on the plate.

Notes

  • Chicken thighs will stay slightly juicier, while chicken breasts offer a leaner option.
  • For extra roasted flavor, broil for 1–2 minutes at the end of cooking.
  • Be sure not to overcrowd the pan, as this can cause the vegetables to steam instead of roast.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
