Ingredients needed
You only need a few healthy and wholesome ingredients to make these easy, one-pan chicken fajita tacos. They’re high in protein, easy to make, and gluten-free. Here is a list of everything you need so you are prepared:
- Chicken: I used skinless and boneless chicken breasts – a great source of lean protein! If needed, you can substitute chicken breasts with chicken thighs (which is the darker meat of the chicken).
- Olive Oil: This helps sear the chicken and sautéing the onions and peppers.
- Yellow Onion: You’ll need one large yellow onion for this recipe. You can also use a white onion or red onion.
- Bell Peppers: This recipe calls for three bell peppers. You can use any color you want, but I love yellow, red, and green to make this meal extra colorful! It’s a great way to sneak in some vitamins, too.
- Lime: Adds acidity and brightness to the dish. Lime juice enhances the flavors of the chicken and vegetables.
- Cilantro: This herb adds a fresh, herbaceous flavor to the tacos. It complements the other ingredients well and adds a pop of color.
- Tortillas: Grab 8 – 10 of your favorite type of tortillas. You can use flour or whole wheat, and if you’re gluten-free, you can use almond flour, chickpea flour, or corn.
- Fajita Seasonings: I left a quick and easy fajita seasoning recipe below. You need chili powder, ground cumin, garlic powder, and paprika. It’s so good, and you can triple the recipe and store it for later!
- Toppings: Feel free to add salsa, pico de gallo, avocado, guacamole, sour cream, and cheese on top of your healthy chicken fajita tacos.

How to make chicken fajita tacos
Everyone is going to love this easy, 25-minute dinner recipe. The chicken is super moist and flavorful, and the tacos are gluten-free and healthy! Here are detailed step-by-step instructions with pictures for visual reference so any level cook can make these chicken fajita tacos. The full recipe and ingredient measurements are at the bottom of this page in the recipe card.
Step 1:
In a small bowl, prepare the fajita seasoning by mixing chili powder, ground cumin, garlic powder, paprika, salt, and pepper. Then, set it aside.
Step 2:
Then, pat dry the chicken breasts with paper towels. Using your fingers, evenly coat both sides of the chicken with half of the fajita seasoning. Save the remaining seasoning for later.
Step 3:
Next, heat olive oil in a large sauté pan over medium heat. Add the seasoned chicken breasts and sear for 7 – 8 minutes on each side until cooked. Remove from the pan and let them rest on a plate for 5 minutes.
Step 4:
In the same pan, add sliced onion and bell peppers. Sprinkle the remaining fajita seasoning over them. Sauté for 4 – 5 minutes until softened, stirring frequently to prevent burning.
Step 5:
After the chicken has had time to rest and lock in all its juices, thinly slice the cooked chicken breasts and add them back to the pan with onions and bell peppers, squeeze lime juice over the mixture, and add chopped cilantro. Stir to combine.
Step 6:
Finally, heat tortillas according to preference. Fill each tortilla with the chicken and vegetable mixture. Serve immediately with optional toppings like salsa, pico de gallo, avocado, guacamole, sour cream, and cheese.
Expert recipe tips:
- Let the Chicken Rest: Allow the chicken to rest for 5 minutes before cutting. This is my #1 tip for chicken fajita tacos. If you cut the chicken too soon after cooking, the juices will leak out, resulting in dry chicken strips. Letting the chicken rest untouched for 5 minutes ensures that all the juices get locked inside, leaving the chicken extra moist.
- Season Generously: Don’t skimp on the fajita seasoning when coating the chicken. Be generous with the seasoning to ensure every bite is packed with flavor.
- Use Chicken Thighs or Breast: Opt for chicken thighs instead if you don’t have chicken breasts. They offer juiciness and flavor that work wonderfully in fajita tacos.
- Ensure Hot Olive Oil: Make sure the olive oil is hot before adding the chicken. If the oil isn’t hot enough, the chicken won’t sear properly, potentially resulting in a rubbery texture.
- Make Them Gluten-Free: While I used flour tortillas in this recipe, you can easily make these tacos gluten-free by opting for corn, almond, chickpea, or cassava flour tortillas.
- Make Them Low-Carb & Keto: For a low-carb and keto-friendly option, serve these chicken fajita tacos in romaine or butter lettuce taco shells. This substitution maintains the delicious flavors while accommodating dietary preferences.
Fajita taco topping ideas:
- Guacamole
- Salsa (salsa verde, pico de gallo, or your favorite variety)

Frequently Asked Questions
Are chicken fajitas healthy?
Chicken fajitas can be healthy when prepared with lean protein, plenty of vegetables, and limited refined oil. This recipe is high in protein and gluten-free, made with simple and wholesome ingredients and a bit of olive oil for healthy fats. They taste clean and light!
Can I use chicken thighs instead of chicken breast?
You can use chicken thighs instead of chicken breast for juicier and more flavorful chicken fajita tacos. Cook the chicken thighs for approximately 8-10 minutes per side or until they are fully cooked through. Adjust cooking time as needed depending on the thickness of the thighs, and ensure you let them sit before slicing.
Can I use taco seasoning for chicken fajitas?
If you don’t have all the spices on hand for the fajita seasoning, you can use pre-made taco seasoning instead.
How can I make these tacos spicier?
For extra heat, you can add chopped jalapeños or a dash of hot sauce to the chicken and vegetable mixture.
Are there any low-carb options for serving chicken fajita tacos?
You can serve the chicken fajita filling over lettuce leaves or use low-carb tortillas to reduce the carb content.
Are these chicken tacos gluten-free?
Yes, these chicken fajita tacos can be made gluten-free. Use gluten-free tortillas such as corn tortillas, almond flour, chickpea, or cassava flour tortillas instead of traditional flour tortillas.
Can I grill the chicken and vegetables instead of cooking them on the stove?
Yes, grill the seasoned chicken breasts and vegetables on medium-high heat until cooked through and charred, about 7-8 minutes per side for chicken and 4-5 minutes for vegetables. Let the chicken rest, slice, and assemble the tacos as usual.
Can I meal prep this recipe?
Yes! This is one of my favorite meal prep recipes. Save extras in the fridge and enjoy them throughout the week. I recommend storing the chicken and veggies separately from the tortillas so they don’t get soggy.
Can I use shrimp instead of chicken?
Yes, you can use shrimp instead of chicken for your tacos. Simply season and cook the shrimp until they’re opaque and cooked through, about 2-3 minutes per side. Then, assemble your tacos with your favorite toppings. Feel free to check out these Baja shrimp tacos too!
How to store and reheat leftovers:
Storing: For best results, store the chicken fajitas separately from the tortillas so they don’t get soggy. Place leftover chicken fajitas into airtight containers and store them in the refrigerator for 4 – 5 days.
Reheating: Reheat the chicken fajita filling in the microwave for 1 – 2 minutes until warm. Lightly toast the tortillas separately or warm them in the microwave with a damp paper towel wrapped around them.
