Summer grilling doesn’t have to involve complicated marinades or hours of preparation to deliver incredible flavor. These Pesto Chicken Skewers with Zucchini prove that a handful of fresh ingredients can create a colorful, satisfying meal that’s equally at home on a busy weeknight or at a weekend backyard barbecue. Juicy chunks of chicken are coated in fragrant basil pesto before being threaded onto skewers with tender zucchini, then grilled until lightly charred and finished with an extra brush of fresh pesto.

The combination is simple, but every ingredient has a chance to shine. The pesto infuses the chicken skewers with the bright flavors of basil, garlic, Parmesan, and olive oil, while the zucchini develops sweet, smoky notes as it cooks over the grill. A squeeze of fresh lemon and a sprinkle of Parmesan just before serving brighten the entire dish, creating a meal that’s both comforting and refreshingly light.

Whether you’re looking for a quick dinner, a meal-prep favorite, or an easy recipe for entertaining guests, these chicken skewers are a delicious way to celebrate the flavors of summer.

Why You’ll Love These Chicken Skewers

One of the best things about this recipe is how quickly it comes together. While a longer marinating time adds even more flavor, even a brief 20-minute soak in pesto gives the chicken skewers a wonderful herbaceous taste that pairs beautifully with the smoky flavor of the grill. From start to finish, dinner can be on the table in about 40 minutes.

These chicken skewers are also wonderfully versatile. They can be served as a complete meal alongside rice or grilled vegetables, tucked into warm pita bread, sliced over salads, or paired with pasta for a heartier dinner. They’re equally delicious fresh off the grill or chilled for lunch the next day.

Because the recipe relies on seasonal zucchini and fresh basil pesto, it naturally feels vibrant and colorful without requiring a long list of ingredients. The result is a meal that’s impressive enough for guests while remaining approachable for everyday cooking.

Why Pesto Works So Well on the Grill

Pesto is much more than a pasta sauce—it also makes an excellent marinade for grilled meats. Its combination of basil, garlic, Parmesan cheese, pine nuts, and olive oil coats the chicken with layers of flavor while helping keep it moist during grilling.

The olive oil lightly protects the surface of the chicken from drying out over high heat, while the garlic and herbs infuse the meat as it marinates. Because Parmesan can brown quickly over direct heat, it’s best to reserve a portion of the pesto for brushing onto the skewers after they’ve finished cooking. This preserves the pesto’s bright green color and fresh basil flavor while adding another burst of richness just before serving.

A final squeeze of fresh lemon juice ties everything together, balancing the richness of the pesto with bright citrus that makes every bite taste fresh.

Ingredient Highlights

Chicken

Boneless, skinless chicken breasts or thighs both work well in this recipe. Chicken thighs remain especially juicy on the grill, while breasts provide a leaner option. Whichever you choose, cutting the chicken into evenly sized cubes ensures every piece cooks at the same rate.

Zucchini

Fresh summer zucchini is one of the season’s most abundant vegetables, making it a natural partner for these chicken skewers. Thick slices hold their shape beautifully on the grill while becoming tender with lightly caramelized edges.

Basil Pesto

Homemade pesto offers the brightest flavor, but a good-quality refrigerated store-bought pesto is an excellent time-saving option. Reserve some of the pesto before marinating the chicken so you have a fresh portion to brush over the finished skewers.

Olive Oil & Lemon

A drizzle of olive oil helps keep the zucchini from sticking to the grill, while fresh lemon juice brightens the finished dish and balances the richness of the pesto.

Garnishes

Fresh basil leaves, grated Parmesan cheese, toasted pine nuts, and lemon wedges add texture, color, and extra flavor without overwhelming the grilled ingredients.

Recipe: Pesto Chicken Skewers with Zucchini

Makes 4 servings

Ingredients

• 1½ pounds boneless, skinless chicken breasts or thighs, cut into 1½-inch cubes
• 2 medium zucchini, sliced into ¾-inch thick rounds or half-moons
• ½ cup basil pesto, divided
• 2 tablespoons olive oil
• 1 tablespoon fresh lemon juice
• 1 teaspoon kosher salt
• ½ teaspoon freshly ground black pepper
• ½ teaspoon garlic powder (optional)

For Garnish:

• Fresh basil leaves
• Grated Parmesan cheese
• Lemon wedges
• Toasted pine nuts (optional)

Instructions

1. If using wooden skewers, soak them in water for at least 30 minutes to prevent burning. Preheat a grill to medium-high heat and lightly oil the grates.
2. Reserve ¼ cup of the pesto for serving. In a large bowl, combine the remaining pesto with the olive oil, lemon juice, salt, pepper, and garlic powder if using. Add the chicken and toss until evenly coated. Let marinate for at least 20 minutes or up to 4 hours in the refrigerator.
3. Lightly toss the zucchini slices with a drizzle of olive oil and a pinch of salt and pepper.
4. Thread the chicken and zucchini alternately onto the skewers, leaving a small amount of space between each piece to encourage even cooking.
5. Place the skewers on the preheated grill. Cook for 10 to 12 minutes, turning every 2 to 3 minutes, until the chicken reaches an internal temperature of 165°F and the zucchini is tender with light grill marks.
6. Transfer the skewers to a serving platter and immediately brush them with the reserved pesto.
7. Sprinkle with grated Parmesan cheese and toasted pine nuts, if using. Garnish with fresh basil leaves and serve with lemon wedges for squeezing over the top.

Easy Variations

One of the best qualities of these skewers is how easily they can be adapted to whatever is fresh and available. Cherry tomatoes add juicy bursts of sweetness, while chunks of red onion become wonderfully caramelized on the grill. Bell peppers contribute vibrant color and slight sweetness, and mushrooms soak up the pesto beautifully.

If you’d like to change the protein, shrimp, turkey breast, or pork tenderloin all work well with the same pesto marinade. Simply adjust the cooking time based on the protein you choose.

For those who enjoy a little heat, stir crushed red pepper flakes or a spoonful of Calabrian chili paste into the pesto before marinating the chicken. A dairy-free pesto made without Parmesan is another easy substitution for those with dietary restrictions.

Tips for Perfect Grilled Chicken Skewers

Uniform pieces of chicken are the key to evenly cooked skewers. Aim for cubes that are roughly the same size so every piece finishes cooking at the same time.

Avoid overcrowding the skewers. Leaving small gaps between the chicken and zucchini allows heat to circulate more evenly, resulting in better browning and more consistent cooking.

Before adding the chicken skewers, lightly oil the grill grates to minimize sticking. Turn the skewers every few minutes rather than leaving them in one position, allowing each side to develop attractive grill marks.

Finally, resist the temptation to brush on additional pesto during the last few minutes of grilling. Fresh pesto is at its best when added after cooking, preserving its bright color and fresh basil flavor.

Serving Suggestions

These skewers pair beautifully with many classic summer side dishes. Lemon herb rice or buttery orzo creates a hearty meal, while grilled corn on the cob celebrates another seasonal favorite. A Caprese salad with ripe tomatoes and fresh mozzarella complements the basil pesto, and grilled asparagus or mixed greens tossed in a simple lemon vinaigrette keep the meal light and fresh.

Warm garlic bread is perfect for soaking up any pesto that drips onto the plate, while a chilled glass of sparkling lemonade or iced tea completes the relaxed summer menu.

Storage & Reheating

Store leftover chicken and zucchini in an airtight container in the refrigerator for up to three days. For the best results, remove the ingredients from the skewers before storing, making reheating much easier.

Warm leftovers gently in the microwave or in a covered skillet over medium-low heat until heated through. The chicken is also delicious served cold over salads, tucked into wraps, folded into pasta, or added to grain bowls for quick lunches throughout the week.

Pesto Chicken Skewers with Zucchini are everything a great summer meal should be—fresh, colorful, easy to prepare, and full of bright seasonal flavor. The combination of juicy grilled chicken, tender zucchini, fragrant basil pesto, and fresh lemon creates a dish that’s both satisfying and surprisingly light.

Whether you’re firing up the grill for a casual family dinner or hosting friends for an evening outdoors, these skewers are sure to become a warm-weather favorite. With just a few fresh ingredients and minimal preparation, they deliver restaurant-worthy flavor while celebrating some of summer’s very best produce.
