How to Prepare Best Chicken Fajitas

Step 1: Marinate the Chicken
In a large mixing bowl, combine the fresh squeezed lime juice, oil, minced garlic, ground cumin, salt, and ground chili. Whisk the mixture until well combined. Add the chicken thighs to the bowl, ensuring they are well coated with the marinade. Cover the bowl and let it marinate in the refrigerator for at least 30 minutes (or up to 2 hours for more flavor).
Step 2: Prepare the Vegetables
While the chicken is marinating, wash and slice the bell peppers and red onion. Aim for uniform strips to ensure even cooking. Set the vegetables aside.
Step 3: Cook the Chicken
Heat your skillet over medium-high heat. Once hot, add the marinated chicken thighs, cooking for about 5-7 minutes on each side, or until they reach an internal temperature of 165°F (75°C) and have a nice golden-brown color. Remove the chicken from the skillet and let it rest for a few minutes before slicing.
Step 4: Sauté the Vegetables
In the same skillet, add the sliced bell peppers and red onion. Sauté for about 5-6 minutes, stirring frequently, until they are tender yet still vibrant and crunchy.
Step 5: Slice the Chicken
Once the chicken has rested, slice it into thin strips. Add the sliced chicken back into the skillet with the vegetables and toss everything together. If desired, sprinkle with fresh chopped cilantro for added flavor.
Step 6: Serve
Serve the chicken and vegetable mixture warm, accompanied by sliced avocados. You can also serve with warm tortillas, sour cream, or your favorite salsa for a full fajita experience!
Nutrition-Minded Tweaks

- For a lower-calorie option, you can substitute chicken thighs with skinless, boneless chicken breasts.
- Incorporate more vegetables like zucchini or mushrooms for added nutrients.
- Use whole wheat tortillas instead of regular ones for a healthier wrap.
- Skip the oil or use a non-stick spray to reduce fat content when cooking.
Missteps & Fixes
If your chicken is tough, it may have been overcooked. Always keep an eye on the internal temperature and let it rest before slicing to retain moisture.
- If the marinade isn’t flavorful enough, allow your chicken to marinate longer, or add more spices to the mix.
- For veggies that are too soft, reduce the cooking time and ensure you’re using high heat for a quick sautĂ©.
- If you want more spice, add additional ground chili or a splash of hot sauce while cooking.
Leftovers & Meal Prep
The Best Chicken Fajitas make excellent leftovers! Store any leftover chicken and veggies in an airtight container in the refrigerator for up to 3 days. Simply reheat them in the microwave or on the stovetop. You can also use the leftovers in salads, grain bowls, or wraps for a quick lunch option. For meal prep, consider portioning out the fajitas with sides of avocado and tortillas for easy grab-and-go meals throughout the week.
