In short: blend a bright lemon‑basil pesto, thin half of it into a marinade, coat the chicken and chill briefly, then grill the chicken, vegetables, and lemon halves. Finish with reserved pesto, lemon zest, and flaky salt for a simple high‑protein summer meal.

1. Make the pesto. Pulse garlic, pine nuts, basil, and lemon zest in a food processor. Add salt, red pepper flakes, and lemon juice, then stream in olive oil until the mixture is combined but still slightly textured. Stir in Parmesan if using and set aside.
2. Prepare the marinade. Transfer half the pesto to a shallow bowl and whisk in extra lemon juice and olive oil to loosen it into a pourable marinade. Reserve the remaining pesto for serving.
3. Marinate the chicken. Season chicken with salt and pepper, coat with the lemon pesto marinade, cover, and refrigerate at least 30 minutes (1–4 hours is best).
4. Prep the vegetables. Toss zucchini, asparagus, and bell peppers with olive oil, salt, and pepper. Preheat the grill to medium‑high and oil the grates.
5. Grill the chicken. Grill chicken about 6–7 minutes per side until lightly charred and cooked through (165°F internal). Let rest before slicing.
6. Grill vegetables and lemons. Grill zucchini, peppers, and asparagus until tender with charred edges. Finish lemons cut‑side down until caramelized.
7. Assemble and serve. Arrange arugula, grilled chicken, and vegetables on a platter. Spoon reserved pesto over the top, garnish with grilled lemons, extra lemon zest, and flaky salt.

Recipe Substitutions & Questions

Customize the recipe easily to match your pantry or dietary needs:

• Parmesan: Omit for dairy‑free or use a dairy‑free alternative.
• Pine nuts: Swap toasted walnuts, almonds, cashews, pepitas, or sunflower seeds.
• Chicken: Boneless skinless thighs work well and stay juicy on the grill.
• Basil: Mix basil with parsley if needed; basil gives the most classic pesto flavor.
• Vegetables: Swap in summer squash, red onion, mushrooms, broccoli, or eggplant.
• Greens: Use mixed greens, spinach, or butter lettuce instead of arugula.
• Spice: Omit red pepper flakes for a milder pesto.
• No grill? Use a grill pan or roast everything in the oven until the chicken reaches 165°F and vegetables are tender.

Tips for the best lemon pesto chicken

• Don’t skip the extra lemon juice and olive oil in the marinade — they loosen the pesto so it coats the chicken evenly and add brightness.
• Cut zucchini on the diagonal and keep pepper pieces large to avoid them slipping through the grates and to highlight grill marks.
• Grills vary, so use the suggested times as a guide and watch for charred edges and a chicken temperature of 165°F.

FAQs

Can I use store‑bought pesto?

Yes. Choose a high‑quality basil pesto and stir in fresh lemon juice and zest to brighten it and mimic the homemade lemony profile.

How do I know when the chicken is done?

Use a meat thermometer: the thickest part should register 165°F. The meat should feel firm and release clear juices. Let it rest 5 minutes before slicing.

Can I make this ahead?

Yes. Marinate the chicken up to 24 hours. You can grill everything ahead and store components separately—chicken, vegetables, and pesto—to keep flavors fresh for up to 4 days.
