Who doesn't love fajitas? This easy low calorie chicken fajitas recipe is a great way to prepare a nutritious and delicious meal everyone in your household will appreciate. The best part? The whole thing comes together in one skillet for easy clean-up
The chicken is marinated in extra virgin olive oil and simple fajita spices, so it's extra tender and packed with flavor. The vibrant peppers and onions add another element of fantastic flavor. I love colorful dishes, so I used a trio of bell pepper colors, but the choice is yours!
These fajitas are perfect with corn tortillas, flour tortillas, or lettuce wraps. I love assembling a spread of healthy fajita toppings so everyone can customize the fajitas to their tastes. As a result, there are never any leftovers!

- It's made with low-carb and low-calorie ingredients.
- It's quick, easy, and a great recipe for beginners in the kitchen.
- The serving and topping options are endless!
Ingredients You'll Need
- Fajita Marinade: A simple blend of extra virgin olive oil, dried oregano, salt, garlic powder, and chili powder tenderizes the chicken and adds a savory, smokey, and mildly spicy flavor.
- Chicken Breast: Patted dry and cut into strips. You can also use boneless, skinless chicken thighs if you like.
- Bell Peppers: Use a few different colors! Red bell pepper, orange, bell pepper, and yellow bell pepper are sweet and citrusy, while green bell pepper is more savory. They each have a decent amount of fiber and are high in vitamin C, vitamin K1, vitamin E, vitamin A, folate, and potassium.
- Onion: I used yellow onion, but white and red onion are also great in fajitas.
- Lime Juice: A squeeze of lime juice over the top at the end enhances the flavor.
- Cilantro: To add a pop of vibrant, herby flavor. If you're not a fan of cilantro, you can use parsley instead.
Step-By-Step Instructions
Step 1: Marinate chicken.
Mix oregano, garlic powder, salt, chili powder, and oil in a large bowl. Add sliced chicken and toss to coat the pieces in marinade. Set in the fridge to marinate for 15-30 minutes.
Step 2: Cook fajita vegetables.
Meanwhile, heat olive oil in a large skillet over high heat. Once hot, add the onions and peppers. Season with chili powder and salt, and sauté until the veggies begin to soften. Then, transfer them to a plate, and set it aside.
Step 3: Cook chicken.
Lower the heat to medium, add the chicken, and sauté until the chicken is cooked and no longer pink.
Step 4: Combine and serve.
Add the peppers and onions to the skillet, squeeze fresh lime juice over the top, and sprinkle in cilantro. Give everything a good stir, and serve hot with lettuce wraps or tortillas and your favorite fajita toppings.

Expert Tips
- Take time to slice the chicken and the veggies the same size so everything cooks evenly.
- Increasing the marinating time will make the chicken even better. It's best marinated between 6 and 24 hours.
- Your skillet needs to be HOT, or the vegetables may become soggy. They're best cooked quickly over high heat.
- To achieve fajita chicken with tasty charred edges, cook the chicken in the skillet mostly undisturbed, stirring only a few times during the cooking process.
Variations
Seasonings - Feel free to add more dry spices to the marinade mixture, like cayenne, cumin, and paprika. You can also use 2-3 teaspoons of store-bought fajita or taco seasoning.
Protein - This easy fajita-making method is also excellent for steak, shrimp, and vegetarian fajitas.
- Steak fajitas - Marinate strips of a skirt of flank steak for 2 to 8 hours before searing in a hot skillet.
- Shrimp fajitas - Marinate large shrimp for 1 to 8 hours, then cook, only flipping once, in a hot skillet.
- Veggie fajitas - Hold the meat and load up on vegetables like broccoli, cauliflower, zucchini, yellow squash, and carrots.
Storing & Freezing
Storing: Let the chicken and veggies cool, then store leftover low calorie chicken fajitas in an airtight container in the fridge for up to 3 days.
Freezing: Cooked fajita vegetables won't hold up in the freezer, but you can freeze the chicken in an airtight bag for up to 3 months—Thaw in the fridge before reheating.
Recipe FAQ‘s
The precise number of calories in chicken fajitas will vary depending on how they are served. For example, a serving of these chicken fajitas with peppers and onions is about 250 calories (not including tortillas or toppings).
I like serving fajitas with a selection of nutritious fajita toppings, like shredded lettuce, sliced avocado, guacamole, salsa, pico de Gallo, and lime wedges, cilantro, jalapeno slices, Greek yogurt, and freshly grated cheese.
These fajitas are great with refried beans or black beans and Spanish rice. For a low-carb side dish, try cilantro lime cauliflower rice.
Fajita meat is traditionally marinated and cooked before it's sliced, but for these easy chicken fajitas, the chicken is cut into strips and marinated before sauteing. For tender chicken strips, slice the meat against the grain (perpendicular to the direction of the grain).
