Ingredients

Chicken and Vegetables

  • 1 lb. boneless skinless chicken breasts, cut into strips
  • ½ red bell pepper, sliced
  • ½ green bell pepper, sliced
  • ½ onion, sliced

Seasoning and Dressing

  • 2 tbsp. olive oil
  • 2 tbsp. lime juice
  • 2 tsp. minced garlic
  • 2 tbsp. cilantro, chopped
  • 1 tsp. chili powder
  • 1 tsp. cumin
  • ½ tsp. oregano
  • ½ tsp. paprika
  • Salt and pepper, to taste

Instructions

  1. Preheat Oven: Preheat your oven to 425°F (220°C) and prepare a baking sheet by spraying it lightly with cooking spray. This prevents sticking and helps crisp the ingredients.
  2. Prepare Ingredients on Sheet Pan: Arrange the sliced chicken breasts, red and green bell peppers, and onion evenly on the prepared baking sheet.
  3. Add Oil and Seasonings: Drizzle the olive oil over the chicken and vegetables. Add the lime juice, minced garlic, chopped cilantro, chili powder, cumin, oregano, paprika, along with salt and pepper to taste directly on the sheet pan.
  4. Toss to Coat: Using tongs or a spatula, toss everything on the pan to ensure the chicken and vegetables are evenly coated with the oil and seasoning mixture.
  5. Bake: Place the baking sheet in the preheated oven and bake for about 20 minutes, or until the chicken is fully cooked through and the vegetables are tender yet slightly crisp.
  6. Serve: Serve the fajitas as they are for a low-carb meal, or add them to low-carb tortillas or over cauliflower rice as desired.

Notes

  • For extra heat, add a pinch of cayenne pepper or sliced jalapeños before baking.
  • You can customize the vegetables by adding sliced mushrooms or zucchini if desired.
  • Make sure the chicken strips are evenly sized to ensure even cooking.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
  • Reheat gently in the oven or on the stovetop to retain the best texture.
