These well-seasoned chicken fajitas are so easy to make. Quickly sauté peppers and onions, then pan-fry chicken strips. Mix everything together and serve!

These chicken fajitas are one of my favorite weeknight dinners. They’re easy, flavorful, and - just as important - ready fast. From start to finish, this recipe is ready in about 30 minutes, including chopping the vegetables. Mexican food is always delicious! In addition to these fajitas, I enjoy recipes like stuffed jalapenos, slow cooker carnitas, and keto taco salad.
Ingredients and Variations
See the recipe card for exact measurements. Here are my comments on some of the ingredients.
- Vegetables: Onions and bell peppers. I like to use three different colors of peppers – it looks so pretty!
- Chicken: I use boneless, skinless chicken breasts, thinly sliced.
- Spices: Salt and pepper, chili powder, smoked paprika, garlic powder, dried oregano, and red pepper flakes.
- Avocado oil: This oil has a neutral flavor and a high smoke point, making it ideal for high-heat cooking. Sometimes, I use ghee instead.
Instructions
The detailed instructions for making this recipe are included in the recipe card below. Here's an overview of the steps:
Slice the chicken and vegetables. Combine the spices. Season the veggies with half the seasoning mix and cook them. Set aside.
Season the chicken with the second half of the seasoning mix and cook it.
Add the vegetables back to the skillet and cook briefly. Serve immediately.
Recipe FAQs
Fajitas are a Tex-Mex dish of marinated and grilled strips of meat (beef or chicken) served on top of cooked onions and peppers. They are typically served with soft tortillas, which the diners stuff with the meat/vegetable mixture. Popular toppings include sour cream, salsa, guacamole, and shredded cheese.
Yes. I often do, as shown in the video below, but they release water into the dish. The solution is to thicken the cooking liquids by stirring in a cornstarch slurry – 1 tablespoon of cornstarch mixed with 1 ½ tablespoons of cold water.
You can, and it will make the chicken more tender. But you don't have to. Since making this recipe quickly is a top priority for me, I don't marinate the chicken, and it still comes out tasty and juicy.
If you'd like to marinate the chicken, mix half the spices with a tablespoon of olive oil and a tablespoon of lime juice. Place the chicken strips in a resealable bag and add the marinade, spreading it all over the chicken. Seal and marinate for two hours in the fridge.
You can keep the leftovers in an airtight container in the fridge for 3-4 days. Reheat them covered in the microwave at 50% power. You can also freeze the cooled leftovers for up to three months.
Serving Suggestions
Traditionally, chicken fajitas are served in flour tortillas. But they’re just as good simply piled on a plate. Sometimes, I serve them in lettuce cups or on top of cauliflower rice.
You can top the fajitas with guacamole, sour cream (as shown in the photo below), salsa, and/or shredded cheese.

Ingredients
Seasoning mix:
- 1 teaspoon sea salt
- ¼ teaspoon black pepper
- 2 tablespoons chili powder
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- ½ teaspoon dried oregano
- ½ teaspoon red pepper flakes
Fajitas:
- 3 medium bell peppers - cut into thin strips; or 1 pound of frozen sliced peppers
- 1 medium onion - thinly sliced
- 2 pounds boneless skinless chicken breast - cut into strips
- 2 tablespoons avocado oil
Optional, to thicken the sauce if using frozen peppers:
- 1 tablespoon cornstarch - see notes below
- 1 ½ tablespoon cold water
Instructions
- In a small bowl, combine the seasoning ingredients: sea salt, black pepper, chili powder, smoked paprika, garlic powder, dried oregano, and red pepper flakes. Divide the mixture into two bowls. One will be used to season the veggies, and the other will be used to season the chicken.
- Heat 1 tablespoon of the oil in a large, deep skillet over medium-high heat. Add the bell peppers, onions, and half the seasoning mix. Cook, stirring often, until just tender, about 5 minutes. If the bottom of the skillet becomes too dry, add water, a tablespoon at a time. You can also reduce the heat to medium.
- Using a slotted spoon, remove the vegetables to a plate. Add the remaining oil to the skillet, then add the chicken slices and the second half of the seasonings. Stir-fry until the chicken is almost fully cooked, about 4 minutes. Again, if the bottom of the skillet becomes too dry while you cook the chicken, add a splash of water.
- Return the vegetables to the skillet. Stir-fry everything together for 1-2 more minutes until the chicken is fully cooked and the dish is heated through.
- Serve the fajitas in bowls, drizzled with the pan juices, and topped (if you wish) with salsa, guacamole, sour cream, and/or shredded cheddar. You can also spoon them into warm tortillas or serve them in lettuce cups.
Notes
- If you'd like to marinate the chicken, mix half the spices with a tablespoon of olive oil and a tablespoon of lime juice. Place the chicken strips in a resealable bag and add the marinade, spreading it all over the chicken. Seal and marinate for two hours in the fridge.
- You can thicken the cooking liquids by stirring in a cornstarch slurry – 1 tablespoon of cornstarch mixed with 1 ½ tablespoons of cold water. This is optional and only needed if you've used frozen bell peppers, which release water into the dish.
- The nutrition info does not include cornstarch, tortillas, or toppings.
- You can keep the leftovers in an airtight container in the fridge for 3-4 days. Reheat them covered in the microwave at 50% power. You can also freeze the cooled leftovers for up to three months.

so what do we do with the cornstarch and water?
Vered DeLeeuw says
Hi Michelle,
This is explained under the "Notes" section. I'll add a comment next to these ingredients to clarify that.
You can thicken the cooking liquids by stirring in a cornstarch slurry – 1 tablespoon of cornstarch mixed with 1 ½ tablespoons of cold water. This is optional and only needed if you've used frozen bell peppers, which release water into the dish.

Elizabeth says
Followed recipe exactly as written and it turned out awesome. This was the perfect amount of seasoning; didn’t even need to add additional salt or anything. Served it on flour tortillas with Spanish rice, shredded lettuce, guac, and grated cheese.
