Ingredients

Chicken

  • 4 boneless, skinless chicken breasts (about 1.5 lbs)

Vegetables

  • 2 bell peppers (1 red, 1 green)
  • 1 large onion

Seasoning

  • 2 tbsp olive oil
  • 2 tsp ground cumin
  • 2 tsp chili powder
  • 1 tsp garlic powder
  • Salt & pepper to taste
  • Juice of 1 lime

Instructions

  1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper to prevent sticking and ease cleanup.
  2. Prepare Ingredients: Slice the chicken breasts into thin strips to ensure even cooking. Chop the red and green bell peppers and the large onion into bite-sized pieces for balanced flavor and texture.
  3. Season Chicken and Vegetables: In a large mixing bowl, combine the chicken strips with olive oil, cumin, chili powder, garlic powder, salt, and pepper. Toss thoroughly to evenly coat the chicken with the spices and oil for enhanced flavor.
  4. Arrange on Baking Sheet: Spread the seasoned chicken strips, bell peppers, and onions evenly across the prepared baking sheet to promote even cooking and caramelization.
  5. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes. Cook until the chicken is fully cooked through and reaches an internal temperature of 165°F (74°C), and the vegetables are tender and slightly caramelized.
  6. Finish with Lime: Once out of the oven, drizzle the fajitas with the fresh juice of one lime to brighten the flavors before serving.

Notes

  • For meal prep, store cooked fajitas in an airtight container in the fridge for up to 4 days.
  • Serve with warm flour or corn tortillas, guacamole, salsa, and sour cream for a complete fajita dinner.
  • Adjust the spices based on your heat preference; add cayenne for extra heat or reduce chili powder for milder flavor.
  • Using parchment paper on the baking sheet helps prevent sticking and simplifies cleanup.
