This lemon pesto grilled chicken is marinated in a bright homemade pesto, grilled alongside summer vegetables, and finished with extra pesto and grilled lemons for an easy, high-protein dinner that feels perfect for warm-weather entertaining.
- Make the pesto. Add the garlic, pine nuts, basil, lemon zest, lemon juice, seasonings, and olive oil to a food processor and blend until combined but still slightly textured. Stir in the Parmesan, if using, and set aside.
- Prepare the lemon pesto marinade. Transfer half of the pesto to a shallow bowl and whisk in additional lemon juice and olive oil. This creates a looser marinade that coats the chicken beautifully while reserving the remaining pesto for serving.
- Marinate the chicken. Season the chicken with salt and pepper, then coat it in the lemon pesto marinade. Cover and refrigerate for at least 30 minutes, or up to 4 hours for even more flavor.
- Prep the vegetables. Toss the zucchini, asparagus, and bell peppers with olive oil, salt, and pepper while the chicken marinates. Preheat the grill to medium-high heat and lightly oil the grates.
- Grill the chicken. Remove the chicken from the marinade and grill until lightly charred and cooked through, about 6–7 minutes per side. Transfer to a plate and let it rest before slicing.
- Grill the vegetables and lemons. Grill the zucchini, bell peppers, and asparagus until tender with plenty of charred edges and grill marks. Finish by grilling the lemon halves cut-side down until lightly caramelized.
- Assemble and serve. Arrange the arugula, grilled chicken, and vegetables on a serving platter. Spoon over the reserved pesto, garnish with grilled lemons, lemon zest, and flaky salt, then serve and enjoy.
Recipe Substitutions & Questions
Use the substitutions below to easily customize this Lemon Pesto Grilled Chicken recipe to fit your pantry and/or dietary preferences.
- Parmesan Cheese: Omit the Parmesan for a dairy-free version, or substitute your favorite dairy-free Parmesan alternative.
- Pine Nuts: Swap with toasted walnuts, almonds, cashews, pepitas, or sunflower seeds. Each will provide a slightly different flavor, but all work well in pesto.

- Fresh Basil: If needed, use a combination of basil and parsley, though basil will provide the most classic pesto flavor.
- Zucchini, Asparagus & Bell Peppers: Feel free to swap in other grill-friendly vegetables like summer squash, red onion, mushrooms, broccoli, or eggplant.
- Arugula: Serve over mixed greens, spinach, butter lettuce, or skip the greens altogether.

Tips for the Best Lemon Pesto Chicken
- Don’t skip the extra lemon juice and olive oil in the marinade. It loosens the pesto just enough to coat the chicken evenly while adding extra brightness and flavor.
- Cut the zucchini on a diagonal and keep the bell pepper pieces fairly large. This helps prevent them from slipping through the grill grates and creates beautiful grill marks.
- Every grill cooks a little differently, so use the suggested cook times as a guide and watch for lightly charred vegetables and chicken that reaches an internal temperature of 165°F.
FAQs
Can I use store-bought pesto for lemon pesto chicken?
Yes, you can definitely use store-bought pesto if you’re short on time. I recommend choosing a high-quality basil pesto with simple ingredients (basil, olive oil, nuts, Parmesan, and garlic). Since this recipe relies on that bright lemon flavor, you may want to stir in a little fresh lemon juice and zest to mimic the homemade version and keep the same fresh, zesty profile.
How do I know when grilled chicken is fully cooked?
The most reliable way is using a meat thermometer. For juicy, safe-to-eat chicken, look for an internal temperature of 165°F at the thickest part of the breast. The chicken should also feel firm to the touch and have clear (not pink) juices. I always recommend letting it rest for about 5 minutes after grilling so the juices redistribute and stay locked in.
Can I make lemon pesto chicken ahead of time?
Yes, this is actually a great meal prep recipe. You can marinate the chicken up to 24 hours in advance, and even grill everything ahead of time for easy lunches or dinners throughout the week. Store the chicken, vegetables, and pesto separately so everything stays fresh and the pesto keeps its bright flavor and color.
What vegetables go best with lemon pesto chicken?
This recipe pairs well with summer vegetables that hold up well on the grill. Zucchini, asparagus, and bell peppers are my go-to because they caramelize nicely and don’t fall apart on the grill. You can also mix in mushrooms, red onion, summer squash, or eggplant depending on what you have on hand.
Do I have to grill the chicken and vegetables for this recipe?
No! While grilling gives the best smoky, summery flavor, you can absolutely make this in a grill pan or in the oven. Roast everything at 425°F until the chicken reaches 165°F and the vegetables are tender and lightly browned. You’ll still get a really delicious version of lemon pesto chicken with that same bright, herby flavor.

For the grilled vegetables:
- 2 medium zucchinis, ends trimmed, cut on the diagonal into large slices
- 1 bunch asparagus, tough ends trimmed
- 2 bell peppers (any color), seeded and cut into 2-inch chunks so they have enough surface area to stay on the grates

- 2 teaspoons Kosher salt
- 1 teaspoon freshly ground black pepper
For the grilled lemon and garnish:
- 2 lemons, halved crosswise
To Serve:
- 4 handfuls fresh arugula, (optional)
- Reserved pesto, for dolloping and dipping
- Extra lemon zest, for garnish
- Flaky salt
Instructions
For the Pesto:
- Place the garlic, pine nuts, basil, and lemon zest in a high speed blender or food processor and pulse until the mixture becomes sandy.
- Add the salt, red pepper flakes, and 3 tablespoons lemon juice and pulse to combine. With the machine running on low, slowly stream in the ½ cup olive oil, scraping down the sides intermittently, until the pesto is well combined but still a bit textured. If using Parmesan, stir it in and set the pesto aside.
For the Lemon Pesto Marinade:
- Place about one half the prepared pesto in a shallow dish or bowl. Add 3 tablespoons of fresh lemon juice and 3 tablespoons of olive oil, stirring until the mixture loosens into a pour over marinade. Taste and add a pinch of extra salt if needed.
For the Grilled Chicken & Vegetables:
- Season the chicken all over with salt and pepper. Place the chicken in the marinade, turning to coat thoroughly. Cover and refrigerate for at least 30 minutes but ideally 1–4 hours for maximum flavor and tenderness.
- Place the asparagus, zucchini chunks, and bell pepper chunks on a large sheet pan, drizzle with olive oil and salt and pepper and toss to coat.
- Heat a gas or charcoal grill to medium high heat (about 375–425°F) and lightly oil the grates.
- Remove the chicken from the marinade, letting excess drip off. Grill the chicken for about 6–7 minutes per side, turning once, until the internal temperature reaches 165°F and the edges are lightly charred. Transfer to a clean plate and let rest for 5 minutes, then slice if desired.
- Place the zucchini chunks on the grill, cut side down, and grill for about 4–5 minutes without moving, until you get nice grill marks. Flip and cook for 3–4 minutes more until tender and lightly charred.
- Add the bell pepper chunks to the grill and cook for about 6–8 minutes, turning occasionally, until softened and slightly charred at the edges.
- Place the asparagus on the grill, rolling them occasionally so they cook evenly, and grill for 5–7 minutes until crisp tender and lightly browned. Transfer all vegetables to a clean plate or tray; keep them warm if the grill is still hot.
- Place the lemon halves cut side down on the grill for 2–3 minutes, or until the edges are lightly browned and the flesh has softened slightly. Remove and set aside for serving.
To Serve:
- Serve chicken breasts with the vegetables, arugula, and a side of additional pesto for dipping and dolloping. Garnish with grilled lemon halves and a light sprinkle of fresh lemon zest over the top, plus a pinch of flaky salt. Enjoy!
To Store & To Reheat:
- Store leftover chicken, vegetables, and pesto separately in airtight containers in the refrigerator for up to 4 days. Keeping the pesto separate helps maintain its fresh flavor and vibrant color.
- To Reheat: Reheat the chicken and vegetables in a skillet over medium heat until warmed through, or microwave in 30-second intervals until heated to your liking. If using the microwave, cover loosely to help prevent the chicken from drying out. Spoon the reserved pesto over the chicken after reheating rather than heating it with the chicken to preserve its fresh basil flavor.
- This recipe is also delicious served cold or at room temperature the next day over a bed of arugula or mixed greens for an easy meal-prep lunch.
