Method
 

Prep Fajita Chicken
  1. In a small bowl, combine 1/4 cup olive oil, 2 tablespoons lime juice, 3 teaspoons chili powder, 3 teaspoons ground cumin, 1 1/2 teaspoons kosher salt, 1 teaspoon paprika, 1 teaspoon onion powder, 1 teaspoon garlic powder, 1 teaspoon dried oregano, 1/4 teaspoon black pepper, and 1/8 teaspoon cayenne pepper. Whisk to combine.
  2. Place 6-8 boneless, skinless chicken thighs in a medium bowl. Pour the marinade over the chicken and toss to coat. Set aside.
  3. Tip: If you have time, marinate the chicken for an hour or overnight for more flavor.
Prep Fajita Veggies
  1. In a large bowl, combine the red onions, yellow onions, bell peppers, garlic, and fajita seasoning. Set aside.
  2. Tip: Use a mandoline slicer for perfectly even vegetables.
Cilantro Lime Sauce
  1. Add the ingredients for the Cilantro Lime Sauce to a small food processor. Blend until smooth. Transfer to a small bowl, cover, and place in the refrigerator until ready to use.
  2. Tip: Make this sauce a day ahead to let the flavors meld together beautifully.
Cook Chicken
  1. Drizzle approximately 1 tablespoon of olive oil over the flat top of your Blackstone. Move around the cooking surface to coat.
  2. Place the marinated chicken in the oil and let it cook for 3-4 minutes per side or until it reaches an internal temperature of about 162°F.
  3. The chicken will continue to cook as it rests, reaching 165°F during that time. Add additional olive oil as needed while cooking. Transfer the chicken to a plate to rest.
  4. Tip: Let the chicken rest for a few minutes before slicing to maintain juiciness.
Cook Veggies
  1. While the chicken rests, you can cook the veggies. Clean the flat top if desired, but it’s not necessary.
  2. Add a tablespoon of olive oil to the flat top and add the veggies. Move them around until soft yet firm, around 3-5 minutes. Transfer them to a plate when done.
  3. Tip: Don’t overcrowd the griddle; it helps everything cook evenly.
Slice Chicken
  1. After the chicken has rested, slice it into 1/2 inch thick strips, or cut into bite-sized pieces if preferred.
  2. Tip: For a more rustic look, consider shredding the chicken with two forks.
Serve
  1. Place the fajita veggies on a warm tortilla. Top with sliced chicken, a drizzle of Cilantro Lime Sauce, fresh chopped cilantro, and a squeeze of fresh lime juice.
  2. Enjoy every bite and the family togetherness this meal brings!

Notes

Serving Blackstone Chicken Fajitas family-style creates a warm atmosphere. Let everyone build their own fajitas, customizing them with extra lime juice, cilantro, or guacamole. Encourage kids to help with toppings or rolling their own fajitas, making it a fun family activity. These fajitas are best enjoyed fresh but can be stored in airtight containers in the fridge for up to 3 days. To reheat, warm the chicken and veggies in a skillet over low heat.
