Ingredients
- 2 teaspoons chili powder
- 1 teaspoon paprika
- 1 teaspoon kosher salt
- 1/2 teaspoon onion powder
- 1/2 teaspoon ground cumin
- 1/2 teaspoon garlic powder
- 1/2 teaspoon sugar
- 1/4 teaspoon cayenne pepper
- 1 1/2 pounds boneless, skinless chicken breasts
- 1 batch fajita seasoning mix (recipe below)
- 1 tablespoon cornstarch
- 1/4 cup plus 2 tablespoons canola oil, divided
- 2-3 limes
- 1/2 green bell pepper, cored and seeded
- 1/2 red bell pepper, cored and seeded
- 1/2 yellow bell pepper, cored and seeded
- 1 yellow onion, peeled and halved
- 12 flour tortillas
Fresh colorful ingredients ready for preparation.
Directions
-
In a small bowl, mix the fajita seasoning with the cornstarch. Add 1/4 cup of the oil and the juice of 1 lime, whisking to combine thoroughly. If the mixture is too thick, thin it with a little water. Set aside.
-
Slice the chicken breasts into 1/4-inch thick slices and place them in a shallow bowl or zippered freezer bag if preparing ahead of time. Pour 2/3 of the fajita seasoning marinade over the chicken, tossing to coat. Set aside.
-
While the chicken is marinating, slice the bell peppers and the onion. Place them in a shallow bowl or zippered freezer bag (if prepping ahead) and add the remaining 1/3 of the marinade. Toss the vegetables until they are well coated, then set aside.
-
In a large cast iron skillet or heavy-bottomed pan over medium-high heat, heat 1 tablespoon of oil. Add the marinated vegetables and cook, stirring occasionally, until the onion softens and the peppers start to color, about 4-5 minutes. Transfer the cooked vegetables to a bowl.
-
In the same skillet, add the remaining oil and cook the marinated chicken undisturbed. Once the bottom of the chicken turns white and is browned, about 4 minutes, flip the chicken and cook for another 4 minutes until cooked through and juices run clear.
-
Add the sautéed peppers and onions back to the skillet with the chicken. Cook everything together for an additional 2-3 minutes to heat through. Remove from the heat and finish with a squeeze of the remaining lime juice.
-
Serve your delicious fajitas with warm flour tortillas, pico de gallo, avocado sauce, crema, and extra lime wedges for a burst of flavor.
Tips & Variations
- Ingredient Substitutions: You can use other proteins like shrimp or beef, and substitute the peppers with your favorite vegetables for added color and flavor.
- Optional Variations: Spice it up by adding jalapeños or a dash of hot sauce for an extra kick. Top with fresh cilantro for added freshness!
- Storage and Reheating Tips: Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently in a skillet over medium heat.
