Ingredients

  • 1/2 cup plus 1 tbsp. extra-virgin olive oil
  • 3 tablespoons minced garlic
  • 2 teaspoons each ground cumin and kosher salt
  • 1 1/2 teaspoons dried oregano
  • 1 teaspoon achiote paste (optional)
  • 1/2 cup fresh orange juice
  • 1/4 cup fresh lime juice
  • 1 (5-lb.) whole chicken, cut into 8 pieces
  • 2 medium-size white onions, cut crosswise into 1-in.-thick slices
  • 4 jalapeno chiles

Method

  • Heat 1/2 cup oil in a small frying pan over medium-low heat. Whisk in garlic, cumin, salt, oregano, and achiote paste (if using). Remove from heat and let stand 10 minutes.
  • Put garlic mixture, orange juice, and lime juice in a large resealable freezer bag. Add chicken, seal bag, and massage it to kick-start marination. Chill 8 hours.
  • Preheat a grill to medium (350° to 450°) with a large cast-iron skillet on one side of grill. Remove chicken from marinade; discard marinade. Grill chicken, covered, until an instant-read thermometer registers 165° when inserted into thickest portion of each piece, 20 to 30 minutes; turn often and move to a cooler area of grill as they reach temperature.
  • While chicken cooks, swirl remaining 1 tbsp. oil into hot skillet on grill. Add onion slices and jalapenos and cook, in batches if necessary, until onions are golden brown and tender, about 5 minutes per side, and jalapenos are blistered on all sides, about 8 minutes. Serve onions and jalapenos with chicken.
