4 garlic cloves, finely chopped
1/4 cup chopped fresh oregano
1/4 cup chopped fresh rosemary
1/4 cup olive oil
Kosher salt, freshly ground pepper
2 pounds chicken wings
Combine garlic, oregano, rosemary, and oil in a large resealable plastic bag; season with salt and pepper. Add chicken wings, seal bag, and turn to coat. Chill at least 1 hour or overnight.
Prepare grill for medium heat. Remove wings from marinade and grill, covered and turning occasionally, until golden brown and crisp, 15–20 minutes.
DO AHEAD: Chicken can be marinated 1 day ahead. Keep chilled.
