For the fajitas

  • ¾ lb flank steak
  • 1 lb boneless skinless chicken thighs
  • 1 red bell pepper
  • 1 yellow bell pepper
  • ½ red onion
  • 2 tablespoons olive oil

For the fajita seasoning

  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon paprika
  • 1 teaspoon brown sugar
  • ½ teaspoon oregano
  • ½ teaspoon onion powder
  • teaspoons kosher salt
  • To serve: pico de gallo, flour or corn tortillas


  • Preheat the oven to 375°F.
  • Place flank steak and chicken thighs on a large sheet pan.
  • Slice the bell peppers and red onion into very thin strips. Place on the sheet pan and drizzle everything with the olive oil.
  • In a small bowl, combine the chili powder, cumin, paprika, brown sugar, oregano, onion powder, and kosher salt. Sprinkle evenly over the meat, peppers, and onion, flipping the meat so that it gets seasoned on both sides.
  • Place the sheet pan in the oven and bake for 15–20 minutes, or until the flank steak is done to your liking. I baked it for 17 minutes for medium. Remove the flank steak, place on a cutting board, and cover with foil. Place the sheet pan back into the oven for 10–15 more minutes (total cooking time should be 30 minutes), or until the chicken thighs are cooked through and the peppers are tender.
  • Slice the chicken thighs and flank steak. Serve with pico de gallo and tortillas.


You can buy a pre-made fajita seasoning packet instead of using the seasonings listed here. You can usually find them in the spice aisle or in the Mexican foods aisle.
Nutrition facts include the meat, veggies, olive oil, and seasonings. They do not include pico de gallo or tortillas. 
Make these gluten-free by serving the meat and veggies with corn tortillas.
