Grilled Chicken With Pesto Sauce Recipe: Charred Juiciness With Herb-Infused Drizzle

This recipe delivers perfectly charred chicken paired with a vibrant pesto drizzle that elevates every bite. The high heat of the grill locks in juices while creating a smoky crust.

I developed this method after years of refining my grilling technique, and the fresh herb sauce adds a bright contrast to the rich, smoky chicken. The combination is both rustic and refined.

The chicken quality matters for even cooking and flavor. Boneless, skinless breasts from Whole Foods or Costco work well—look for uniform thickness or pound them yourself to ½-inch. Kosher salt (like Diamond Crystal) gives better texture than table salt. For the pesto, fresh basil should be bright green and fragrant—avoid any with black spots or wilting.

Substitutions are easy for this flexible dish. Chicken thighs stay juicier on the grill (use 2 lbs). If pine nuts are too pricey, walnuts or cashews work at one-third less by volume. Pecorino Romano can replace Parmesan for a sharper flavor. No fresh lemon? Bottled juice in a pinch, but zest is non-negotiable for that bright pop.

Store chicken in the coldest part of your fridge—use within 2 days or freeze for 9 months. Pesto keeps 5 days refrigerated (cover with olive oil) or freezes for 3 months. Toast extra pine nuts—they’re great on salads too.

Step-by-Step Instructions for Grilled Chicken With Pesto Sauce

This method ensures perfectly charred chicken paired with a vibrant, herbaceous pesto drizzle.

Step 1: Marinate the Chicken Breasts

Pound the 1.5 lb boneless skinless chicken breasts to an even ½-inch thickness using a meat mallet. This guarantees uniform cooking and prevents dry, overdone edges.

In a bowl, combine 1 tbsp extra-virgin olive oil, 1.5 tsp kosher salt, 1 tsp black pepper, and the 3 cloves minced garlic cloves. Rub this mixture all over the chicken, ensuring every surface is well coated. Let it marinate for 15-20 minutes at room temperature to absorb the flavors.

Step 2: Grill the Chicken to Charred Perfection

Preheat your grill to medium-high heat (about 400°F). Brush the grates with the remaining 1 tbsp extra-virgin olive oil to prevent sticking. Place the chicken on the grill and cook undisturbed for 5-6 minutes per side.

You’ll know it’s ready to flip when the edges turn opaque and the surface develops deep grill marks. Resist the urge to move the chicken—this ensures a good sear. Cook until the internal temperature reaches 165°F and the juices run clear.

Step 3: Toast the Pine Nuts for Pesto

While the chicken grills, toast the 0.5 cup pine nuts in a dry skillet over medium heat for 3-4 minutes, stirring frequently. The pine nuts are done when they turn light golden brown and emit a nutty aroma. Remove them immediately from the pan to prevent burning.

Let the pine nuts cool slightly before adding them to the pesto. This step deepens their flavor and adds a satisfying crunch to the sauce.

Step 4: Blend the Pesto Sauce

In a food processor, combine the 2 cups fresh basil leaves, toasted 0.5 cup pine nuts, 0.75 cup parmesan cheese, 2 cloves garlic cloves, 2 tbsp fresh lemon juice, and 1 tsp lemon zest. Pulse until the mixture is finely chopped.

With the processor running, slowly drizzle in 2 tbsp extra-virgin olive oil (from the marinate) until the pesto is smooth and creamy. Taste and adjust seasoning with additional kosher salt or black pepper if needed. The pesto should be vibrant green and slightly thick.

Step 5: Serve with a Drizzle of Pesto

Transfer the grilled chicken to a serving platter and let it rest for 5 minutes. This allows the juices to redistribute, ensuring every bite is moist and flavorful.

Spoon the pesto generously over the chicken or serve it on the side for dipping. The contrast of the smoky, charred chicken with the bright, herby pesto creates a balanced and satisfying dish. Serve immediately while warm.

Essential Equipment for This Dish

Grill Setup

You’ll need a reliable grill—my go-to is a Weber Genesis for even heat distribution. For charcoal, I swear by Kamado Joe for that smoky depth. Preheat to 400°F for perfect sear marks on the chicken.

Pesto Tools

A food processor is essential for smooth pesto—I use my Cuisinart 14-cup for large batches. If you don’t have one, a mortar and pestle works for smaller quantities, though it requires more elbow grease.

Prep Essentials

Invest in a meat mallet to pound chicken to even thickness. A digital meat thermometer is non-negotiable for hitting 165°F perfectly. I keep my ThermoPro in my apron pocket during every cook.

Serving Gear

Use tongs (not forks!) to flip the chicken—this keeps juices intact. A basting brush helps apply olive oil to grates. For plating, a slotted spoon lets you drizzle pesto elegantly. 🔥

Optional Upgrades

A cast iron grill press adds weight for better char if your grill lacks a lid. For pesto storage, glass jars preserve freshness better than plastic. I label mine with the date to track shelf life.

Cleanup Helpers

Keep a grill brush handy for post-cook cleanup. A dish scraper removes stubborn pesto residue from the processor. I always have microfiber towels ready for quick spills.
