Basil pesto isn’t just for pasta. We found a way to imbue chicken with basil and garlic that would hold up on the grill.
How did we get enough flavor into the chicken? We used homemade pesto, which tastes stronger and fresher than store-bought. We added the pesto base to separate mixtures for marinating, stuffing, and saucing the chicken.
We found that bone-in chicken breasts had the most flavor. We cut pockets in them to fill with pesto and then marinated the stuffed breasts in more pesto. We added a third dose of pesto in a sauce to serve with the chicken after it was grilled.
Grilled pesto chicken
Start to finish: 1 hour, 30 minutes
4 cups fresh basil leaves
3/4 cup extra-virgin olive oil
5 garlic cloves, peeled
1 1/2 tablespoons lemon juice
Salt and pepper
2 ounces Parmesan cheese, grated (1 cup)
4 (12-ounce) bone-in split chicken breasts, trimmed
Process basil, 1/2 cup oil, garlic, lemon juice, and 3/4 teaspoon salt in food processor until smooth, about 1 minute, scraping down bowl as needed. Transfer 1/4 cup pesto to large bowl and set aside for marinade. Add Parmesan to pesto left in processor and pulse to incorporate, about 3 pulses; transfer 1/4 cup pesto to small bowl and set aside for stuffing. Add remaining 1/4 cup oil to pesto left in processor and pulse to incorporate, about 3 pulses; set aside for serving.
Starting on thick side of breast, closest to breastbone, cut horizontal pocket in each breast, stopping 1/2-inch from edge so halves remain attached. Season chicken, inside and out, with salt and pepper. Place 1 tablespoon pesto reserved for stuffing in each pocket. Tie each chicken breast with 2 pieces kitchen twine to secure. In large bowl, rub chicken with pesto reserved for marinade, cover, and refrigerate for 1 hour.
Preheat gas or charcoal grill to medium-low. Clean and oil cooking grate. Place chicken skin side up on grill (cooler side if using charcoal). Cover and cook until chicken registers 155 degrees, 25-35 minutes.
Slide chicken to hotter side of grill (if using charcoal) or turn all burners to high (if using gas), and flip skin side down. Cover and cook until well browned and chicken registers 160 degrees, 5-10 minutes.
Transfer chicken to platter, tent with aluminum foil, and let rest for 5-10 minutes. Remove twine, carve chicken, and serve with remaining sauce.
