For the Chipotle Chicken Marinade:

  • 4 cloves of garlic, smashed
  • ¼ cup cilantro, roughly chopped (about 1 handful)
  • ¼ cup Chipotle Peppers in Adobo Sauce, about 4 peppers and some of the sauce, recommended brand Embasa (comes in a 7-ounce can)
  • ¼ cup tomato sauce
  • ½ lime juiced
  • 2 tablespoons extra virgin olive oil
  • 1 teaspoon honey
  • 1 teaspoon kosher salt
  • ½ teaspoon fresh ground pepper

For the Grilled Chicken:

  • 2 large boneless skinless chicken breasts

For the Fajitas:

  • 2 tablespoons extra virgin olive oil
  • 2 bell peppers, sliced (I like a combination of green, yellow, and red peppers)
  • ½ red onion, sliced
  • 8 small flour tortillas
  • Optional Toppings: avocado slices, guacamole, sour cream, salsa, shredded cheese, diced tomatoes


For the Chipotle Garlic Marinade:

  • Place all marinade ingredients into the food processor and pulse until everything has broken up and there are no more chunks.
  • Place in a large plastic baggie add the chicken and let marinate from 4 hours, up to 24. *Optional: Reserve ¼ cup for fajitas as a topping or as a final brush on the grill before you marinade.

For the Grilled Chicken:

  • Prepare the grill targeting 400 – 450 degrees Fahrenheit using the two-zone method of grilling (or direct/indirect). Lump charcoal adds the best flavor. Place a grill safe skillet over direct heat to warm up with the grill (we use cast iron).
  • Remove chicken from the marinade. Discard the marinade.
  • Grill the chicken direct for 5 minutes with lid closed, then flip and continue grilling direct another 5 minutes. At this point you should have a nice crust on the chicken, but the inside isn’t close to done yet.
  • While the chicken is grilling direct, add olive oil to the pan and then add the onions and peppers. Stir occasionally and remove when they are soft.
  • Move the chicken to indirect heat and finish until the internal temperature of the chicken reaches 160 – 165 degrees Fahrenheit. Usually about the time we move the chicken to indirect heat, the onions and peppers are done and we remove them also from grill.
  • Slice the chicken and add back to the pan with peppers and onions for serving. Use for fajitas, tacos, or in a salad with your favorite filling. We love sautéed peppers and onions.

For the Fajitas:

  • Warm up your tortillas, and serve them with the chicken, pepper, and onion mixture, and your favorite toppings and sides.
