Equipment

  • Large bowl
  • Sheet pan
  • Knife
  • Cutting board
  • Measuring spoons
  • Spatula

Ingredients
  

  • 1.5 lbs boneless, skinless chicken breasts, cut into strips
  • 1 large red bell pepper, sliced
  • 1 large yellow bell pepper, sliced
  • 1 large orange bell pepper, sliced
  • 1 large onion, sliced
  • 2 tablespoons olive oil
  • 1 packet fajita seasoning or homemade blend
  • 2 tablespoons chili powder
  • 1 tablespoon cumin
  • 1 tablespoon paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon dried oregano
  • ½ teaspoon cayenne pepper optional, for heat
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • Flour or corn tortillas, warmed
  • Salsa, for serving
  • Guacamole, for serving
  • Sour cream, for serving
  • Shredded cheese, for serving
  • Lime wedges, for serving
  • Cilantro, for serving

Instructions
 

  • Preheat your oven to 400°F (200°C).
  • In a large bowl, toss the chicken strips, sliced bell peppers, and sliced onions with olive oil and fajita seasoning (or your homemade blend). Make sure everything is evenly coated.
  • Spread the chicken and veggie mixture in a single layer on a large sheet pan. If necessary, use two sheet pans to avoid overcrowding.
  • Roast in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the veggies are tender-crisp. Stir halfway through cooking to ensure even browning.
  • While the chicken and veggies are roasting, warm your tortillas according to package directions.
  • Once the chicken and veggies are cooked, remove them from the oven and let them rest for a few minutes.
  • Serve the fajitas immediately with warmed tortillas and your favorite toppings: salsa, guacamole, sour cream, shredded cheese, lime wedges, cilantro, etc.

Notes

For maximum flavor, marinate the chicken in the fajita seasoning mixture for at least 30 minutes (or even overnight!) before roasting. A squeeze of fresh lime juice over the cooked fajitas adds a bright, zesty flavor. Adjust the amount of cayenne pepper in the fajita seasoning to control the heat level. Line your sheet pan with parchment paper or aluminum foil for easy cleanup. For a more charred and smoky flavor, broil the fajitas for the last few minutes of cooking, keeping a close eye on them to prevent burning.
