  • Total Time: 30 minutes
  • Yield: 4 servings 1x

Ingredients

Scale
  • Protein:
    • 1 lb boneless, skinless chicken breasts (sliced into 1/4-inch strips)
  • Vegetables:
    • 1 red bell pepper, sliced
    • 1 green bell pepper, sliced
    • 1 yellow bell pepper, sliced
    • 1 large onion, sliced
  • Seasoning Blend:
    • 1 tsp chili powder
    • 1/2 tsp cumin
    • 1/2 tsp smoked paprika
    • 1/2 tsp garlic powder
    • 1/4 tsp salt
    • 1/4 tsp black pepper
  • Other:
    • 2 tbsp olive oil (divided)
    • Juice of 1 lime
    • Optional: tortillas, sour cream, guacamole, shredded cheese, or pico de gallo

Instructions

  • Prepare the Marinade:
    In a bowl, mix lime juice, 1 tbsp olive oil, and all the spices. Add chicken strips and coat thoroughly. Marinate for 15–30 minutes.
  • Prepare the Vegetables:
    Slice peppers and onions into thin strips. Pat dry to remove moisture.
  • Cook the Chicken:
    Heat a skillet over medium-high heat. Add 1 tbsp olive oil and cook the chicken in batches for 4–5 minutes, until golden brown and cooked through (165°F). Set aside.
  • Sauté the Vegetables:
    In the same skillet, add peppers and onions. Cook on medium-high heat for 3–5 minutes, stirring occasionally, until slightly charred but still crisp.
  • Combine and Serve:
    Return the chicken to the skillet with the vegetables. Toss together and heat through for 1–2 minutes. Serve immediately on warm tortillas with your choice of toppings.

Notes

  • Tender Chicken Tip: Slice chicken against the grain for maximum tenderness.
  • Add Heat: For spicier fajitas, add cayenne pepper or diced jalapeños.
  • Make Ahead: Marinate the chicken and slice vegetables up to a day in advance.
