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 ingredients ready for preparation.
Directions
-
In a small bowl, combine the fajita seasoning mix with cornstarch. Add 1/4 cup of the canola oil and the juice of 1 lime, whisking until well combined. If the mixture is too pasty, thin it out with a little water. Set aside.
-
Slice the chicken breasts into 1/4" thick slices and place them in a shallow bowl or zippered freezer bag for meal prep. Pour in 2/3 of the fajita seasoning marinade and toss to coat the chicken evenly. Set aside to marinate.
-
While the chicken is marinating, slice the bell peppers and onion. Place them in another shallow bowl or zippered freezer bag. Add the remaining 1/3 of the marinade and toss the veggies until well coated. Set aside.
-
Heat 1 tablespoon of canola oil in a large cast iron skillet or heavy-bottomed pan over medium-high heat. Add the marinated vegetables and cook, stirring occasionally, until the onion softens and the peppers are vibrant in color, about 4-5 minutes. Once done, transfer the vegetables to a bowl.
-
Add the remaining oil to the skillet. Cook the marinated chicken undisturbed until the bottoms turn white, brown, and the chicken releases its juices, about 4 minutes on each side.
-
Once the chicken is fully cooked, return the pepper and onion mix to the skillet. Stir everything together and cook for an additional 2-3 minutes until warmed through. Remove from heat and squeeze the juice of the remaining lime over the dish.
-
Serve the fajitas with warm flour tortillas, pico de gallo, avocado sauce, crema, and extra lime wedges for that perfect finishing touch!
Tips & Variations
- Ingredient substitutions: You can use shrimp or beef in place of chicken for a different take. For a vegetarian version, try using mushrooms or tofu.
- Optional variations: Feel free to add other veggies like zucchini or mushrooms to the mix for extra flavor and nutrition.
- Storage and reheating tips: Leftover fajitas can be stored in an airtight container in the refrigerator for up to 3 days. When reheating, use a skillet to maintain the texture or microwave briefly.
