Low Carb Chicken Fajitas

Low Carb Chicken Fajitas


For the fajita seasoning:

  • 2 teaspoons chili powder 
  • 1 teaspoons cumin 
  • 1 teaspoon garlic powder 
  • 1 teaspoon onion powder 
  • 1 teaspoon smoked paprika 
  • 1/2 teaspoon salt or to taste 
  • 1/4 teaspoon black pepper or to taste 

For the fajitas:

  • 2 tablespoons olive oil 
  • 2 tablespoons butter divided 
  • 1/4 cup fresh cilantro leaves chopped, plus more for serving 
  • juice from 2 limes divided 
  • 1 teaspoon ground mustard OR 1 tablespoon Dijon mustard paleo/keto brand as necessary 
  • 1½ pounds chicken thighs sliced 
  • 4 medium bell peppers seeded and thinly sliced (I used red, yellow, orange and green) 
  • 1 medium red onion thinly sliced 

For serving:

  • lime wedges 
  • sliced avocado 
  • cauliflower rice or lettuce for serving 


  • Combine all the ingredients for the fajita seasonings. Reserve 1 1/2 teaspoons for the bell peppers.
  • In a medium bowl, combine 2 tablespoons of olive oil, chopped cilantro, lime juice, mustard and 5 teaspoons of the fajita seasonings. Reserve 1 tablespoon of the chicken marinade for drizzling on the chicken at the end. Pour the remainder of the marinade into a large zip-top bag along with the chicken. Press the bag to evenly distribute the marinade and allow to sit while you prepare the vegetables.
  • Slice the onions and bell peppers.
  • Heat 1 tablespoon butter in a 12" skillet over medium-high heat. Add the onions and allow to cook for about 5 minutes, or until softened and fragrant. Add the bell peppers and sprinkle with the reserved 1 1/2 teaspoons of fajita seasonings. If you like the peppers with a nice crunch - cook for about 3-5 minutes. And if you like them softer, leave them on for about 3 minutes longer. Transfer and set aside on a plate.
  • Melt the remaining 1 tablespoon butter on the same skillet and brown the chicken. Cook for 5-6 minutes, or until cooked through. Add the reserved chicken marinade to the skillet and cook for an additional 30 seconds. Remove from heat.
  • Serve over some lettuce, cauliflower rice and with sliced avocados and lime wedges.
