  1. Combine freshly squeezed lime juice, oil, minced garlic, ground cumin, salt, ground chili, and fresh chopped cilantro in a large shallow bowl and mix.
  2. Add the skinless and boneless chicken thighs to this mix of herbs and spices and marinate for about 30 minutes (you can skip the marination if pressed for time).
  3. Place a large skillet or pan (about 12 inches) on the stove over medium heat and heat it until smoking before adding a drizzle of olive oil.
  4. Add the chicken thighs to this hot and oiled pan and sear both sides until nicely charred, golden, and completely cooked through (this will take about 8 minutes per side or more depending on the thickness of the fillets).
  5. Transfer the cooked and grilled chicken thighs to a warm plate and wrap them loosely with some foil.
  6. Add the cut onions and peppers to the same skillet or pan (drizzle extra oil if needed) and cook until the peppers are a little charred but cooked through and the onions have become nice and soft.
  7. Season the cooled peppers and onions with salt and ground pepper and remove the cooked chicken fillets from the foil to cut into appropriately sized strips.
  8. Toss the chicken and vegetables together and garnish your easy chicken fajita with avocado slices and chopped cilantro.
  9. Serve it hot and enjoy!

  • Make this chicken fajita recipe with three differently colored bell peppers or capsicums for the best visual impact. You can use green, red, yellow, orange, or any other colors you can find at your local store.
  • Cook the boneless and skinless thighs whole until completely cooked through, and let them rest before cutting them into strips. This will guarantee juicy chicken thighs while cooking them as strips is likely to dry them out.
  • Use a cast iron skillet to sear the chicken for best results. If you don’t have a cast iron skillet, use a nonstick pan but make sure to get it hot before adding the chicken.
  • To prevent the meat from sticking to the base, remember to season the chicken properly and thoroughly before adding it to the cast iron skillet.
  • This chicken fajita recipe can be made with both chicken thighs and breasts, although thighs generally give juicier results. Feel free to use either based on personal preference.
  • Avoid using store-bought fajita seasoning packets for this easy chicken fajita. Homemade fajita seasoning gives much better results and takes only a handful of extra ingredients. Not to mention you can adjust the taste when you make the seasoning yourself.
  • When adding oil to the cast iron skillet or pan to sear the chicken, don't overdo it. Instead, add just enough to coat the bottom of the skillet or pan.
  • Flip the chicken thigh fillets at least a couple of times while searing to ensure they cook and char evenly.
  • To convert this recipe into a vegetarian fajita recipe, substitute chicken thighs with portobello mushrooms and sauté the mushroom slices with peppers and onions over medium-high heat.
  • Want to make your chicken fajita in the oven? Cut the chicken into strips and add to an oiled baking sheet along with the cut bell peppers and onions. Toss with oil and spice mix and bake for about 25 minutes at 425°F before adding cilantro and lime juice to these sheet pan chicken fajitas.
  • This chicken fajita recipe is versatile, so feel free to try variations with beef, pork, and other vegetables. You can even use it to make easy and quick chicken fajita casseroles.
