Ingredients

Scale
  • 2 large boneless, skinless chicken breasts (about 1 ½ lbs)
  • 4 tablespoons olive oil, divided
  • 2 tablespoons lime juice
  • 1 teaspoon ground chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon paprika
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon fine sea salt (plus more to taste)
  • ½ teaspoon ground black pepper
  • 3 bell peppers (red, yellow, and green), sliced into ¼-inch thick slices
  • 1 medium onion, thinly sliced
  • 8 small flour tortillas, toasted or warmed

Instructions

1. Prepare the Marinade

In a mixing bowl, combine 2 tablespoons of olive oil, 2 tablespoons of lime juice, and all the spices: chili powder, cumin, paprika, onion powder, garlic powder, salt, and black pepper. Stir everything together to create a well-mixed marinade.

2. Season the Chicken

Slice each chicken breast in half lengthwise to create thinner cutlets. This helps the chicken cook evenly and faster. Add the chicken to the bowl with the marinade, turning each piece to coat it fully. Let it sit while you prepare the vegetables. If you have time, marinate the chicken for up to 4 hours for even more flavor.

3. Prepare the Vegetables

Cut the bell peppers into ¼-inch thick slices, making sure to remove the seeds and stems. Slice the onion thinly. Cutting the vegetables evenly ensures they cook at the same rate.

4. Cook the Chicken

Set a large, heavy skillet (such as cast iron) over medium heat. Add 1 tablespoon of olive oil. Once the oil is hot, add the chicken in a single layer. Cook for 3-5 minutes per side until browned and cooked through. Use an instant-read thermometer to check that the internal temperature reaches 165°F. If cooking in batches, transfer the cooked chicken to a cutting board and cover it loosely with foil while cooking the remaining pieces.

5. Cook the Vegetables

In the same skillet, add the remaining 1 tablespoon of olive oil. Add the sliced onions and bell peppers, stirring frequently. Cook for about 5-6 minutes until the vegetables soften and develop some caramelized brown spots. Season with salt and pepper to taste.

6. Slice the Chicken and Combine

While the vegetables are cooking, slice the rested chicken into thin strips against the grain. This ensures tender bites. Once the vegetables are done, return the chicken to the skillet, stirring to combine everything. Remove from heat.

7. Warm the Tortillas

Toast the tortillas on a dry skillet for about 30 seconds per side or warm them in the microwave wrapped in a damp paper towel for 20 seconds. Warm tortillas make a big difference in taste and texture.

8. Assemble and Serve

Spoon the chicken and vegetable mixture onto the warmed tortillas. Squeeze fresh lime juice over the top, garnish with cilantro, and add your favorite toppings like sour cream, salsa, or guacamole.

Notes

  • How to Tell if Chicken is Cooked: The safest way to check doneness is using a meat thermometer. Chicken should reach 165°F internally. If you don’t have a thermometer, slice into the thickest part—there should be no pink and the juices should run clear.
  • Avoid Overcrowding the Pan: If you add too much chicken at once, it will steam instead of searing. Cook in batches if necessary.
  • Slicing the Chicken Correctly: Always cut the chicken against the grain to ensure tender pieces. Cutting with the grain can make the meat chewy.
  • Don’t Overcook the Vegetables: Bell peppers should be softened but still slightly crisp. Overcooked vegetables become mushy and lose their vibrant color.
  • Marinate for More Flavor: Even though this recipe works with a short marination time, letting the chicken sit in the marinade for a few hours will enhance the taste.
