This recipe proves that healthy eating can be bursting with flavor!

Fajitas have long been a beloved staple in many households, offering a delightful blend of protein and vibrant vegetables. Traditionally, many recipes, including those my mom used to make, relied on specific commercial seasonings like Salsa Maggi. This particular seasoning, often described as a mix between a sweet soy sauce and Worcestershire sauce, is known for adding a significant punch of flavor to dishes.

However, as dietary needs evolve and families become more conscious of ingredients, finding cleaner alternatives becomes essential. In our family, with gluten allergies and various sensitivities, the conventional ingredients found in such commercial sauces became less than ideal. This led us on a quest to recreate that familiar, robust flavor profile using wholesome, naturally derived components, ultimately doing away with the need for highly processed seasonings in our cooking.

Our solution came in the form of coconut aminos. This dark, savory sauce, derived from coconut sap and sea salt, has emerged as a fantastic, clean, and healthy alternative. It mirrors the sweet and salty notes of traditional seasonings without any of the undesirable additives. It’s a game-changer, providing just as much depth and flavor as its conventional counterparts, if not more, thanks to its naturally rich umami.

This perfected chicken fajita recipe masterfully combines the subtle sweetness and rich saltiness of coconut aminos with other dynamic ingredients. Fresh apple cider vinegar adds a tangy brightness, while authentic New Mexico chile powder infuses the dish with a moderate, earthy spice that is truly unique. Fresh garlic and aromatic spices round out the flavor profile, creating a sauce that is perfectly balanced – sweet, salty, and spicy – forming the ultimate coating for tender chicken and crisp-tender vegetables. This homemade sauce transforms simple chicken strips and bell peppers into an irresistible, restaurant-quality meal, all prepared in a single skillet for maximum convenience and minimal cleanup.

Essential Ingredients & Smart Substitutions for Perfect Fajitas

Creating truly outstanding skillet chicken fajitas starts with understanding each ingredient and knowing how to make smart substitutions if needed. Here’s a detailed look at what you’ll need to bring this flavorful dish to life:

For the Chicken

• Chicken Breasts: Boneless, skinless chicken breasts are chosen for their lean protein and ease of preparation in this recipe. They cook quickly and absorb flavors wonderfully. For a slightly richer flavor and more tender texture, boneless, skinless chicken thighs can be used as an excellent alternative. Simply adjust cooking time slightly as thighs can take a bit longer.
• Tapioca Starch: Also known as tapioca powder, this gluten-free starch is crucial for achieving that desirable crispy exterior on the chicken when seared. It creates a light, protective coating that caramelizes beautifully. If you don’t have tapioca starch, cornstarch or arrowroot powder are suitable gluten-free substitutes that will yield similar results.
• Garlic Powder: This adds a foundational, subtle garlic taste that adheres directly to the chicken, creating a savory base layer of flavor before the sauce is even added.

For the Irresistible Fajita Sauce

• Coconut Aminos: This is a cornerstone of our healthy fajita sauce, providing a balanced salty and subtly sweet umami flavor without the gluten or soy found in traditional soy sauce. You can typically find coconut aminos in the Asian aisle or near the oils and vinegars section of most major grocery stores. It’s a fantastic clean-eating staple.
• Apple Cider Vinegar: The distinct tartness and hint of sweetness from apple cider vinegar are key to balancing the richness of the sauce and adding a bright, zesty note. In a pinch, white vinegar or white wine vinegar can be used, though they may alter the flavor slightly.
• New Mexico Chile Powder: This isn’t just any chili powder; it’s made solely from pulverized New Mexico chiles, delivering a moderately spicy kick with a deliciously earthy and subtly sweet undertone. While cayenne pepper can provide heat, it won’t replicate the complex flavor profile of New Mexico chile powder. We highly recommend seeking out the authentic variety for the best results; you can often order it online if it’s not available locally.
• Cumin Powder: A small amount of ground cumin is all that’s needed to introduce a touch of smokiness and warmth, harmonizing beautifully with the other spices and enhancing the overall depth of flavor in the sauce.
• Onion Powder: Provides a concentrated, sweet onion flavor that blends seamlessly into the sauce, contributing to its rich savory base.
• Garlic: Freshly minced garlic offers a pungent, robust flavor that stands out more prominently than garlic powder, adding an aromatic depth to the sauce.
• Olive Oil: Either extra virgin olive oil or regular olive oil works perfectly as the base for building the sauce, helping to emulsify the ingredients and carry the flavors.

For the Vibrant Vegetables

• Bell Peppers: Feel free to choose your favorite colors! Red, yellow, and orange bell peppers tend to be sweeter and add a beautiful visual appeal to the dish. Green bell peppers offer a slightly more bitter, earthy flavor if you prefer that profile.
• Red Onion: While white or yellow onions can certainly be used, the natural sweetness of red onion complements the fajita flavors exceptionally well and contributes a lovely pop of color to the final presentation.
• Oil for Cooking: For searing both the chicken and vegetables, we recommend using avocado oil or olive oil. These oils are not only more nutritious but also have high smoke points, making them ideal for cooking at medium-high heat without burning.
• Salt and Pepper: These fundamental seasonings are essential for enhancing the natural flavors of all the ingredients, ensuring the dish is perfectly balanced and delicious.

See the recipe card below for exact quantities and measurements.

1. Prepare the Flavorful Sauce: In a small bowl, whisk together the coconut aminos, apple cider vinegar, a tablespoon of olive oil, minced fresh garlic, New Mexico chile powder, ground cumin, and onion powder. Stir until all ingredients are well combined and the spices are fully incorporated. Set this vibrant sauce aside, allowing the flavors to meld.

2. Perfectly Prep the Chicken: Take your boneless, skinless chicken breasts and slice them evenly into thin, fajita-style strips. This ensures quick and even cooking. Place the chicken strips in a mixing bowl. Season generously with kosher salt, freshly ground black pepper, and garlic powder, tossing to coat. Next, sprinkle in the tapioca powder (or your chosen substitute) and toss again until each piece of chicken is lightly and evenly coated. This coating is key for a crispy sear.

3. Sear the Chicken to Perfection: Heat 2 tablespoons of avocado or olive oil in a large cast-iron skillet over medium-high heat until the oil is shimmering and hot. Cook the chicken in small batches (3-4 batches, depending on your skillet size). It’s crucial not to overcrowd the pan, as this can lower the temperature and cause the chicken to steam instead of sear. Cook each batch for about 4 minutes per side, turning until golden-brown and cooked through. As each batch finishes, transfer the seared chicken to a clean plate or bowl and set aside. You might need to add a little more oil to the skillet between batches to maintain that beautiful sear.

4. Sauté the Colorful Vegetables: Once all the chicken is cooked and removed from the skillet, add another tablespoon of oil to the pan. Add your thinly sliced bell peppers (choose a mix of red, yellow, and orange for visual appeal and sweeter flavor) and the thinly sliced red onion. Sauté the vegetables over medium-high heat for approximately 5 minutes, stirring frequently, until they become tender-crisp and develop a nice char on the edges. This char adds a wonderful depth of flavor characteristic of authentic fajitas.

5. Combine and Thicken the Flavors: Return the cooked chicken to the skillet with the sautéed vegetables. Pour the prepared sauce evenly over all the ingredients in the pan. Reduce the heat to medium-low. Using a wooden spoon, gently scrape any delicious brown bits (fond) from the bottom of the skillet – these bits are packed with flavor and will enrich your fajitas even further. Stir everything together to ensure the chicken and vegetables are well coated in the sauce. Continue to cook for about 4 minutes, stirring occasionally, until the sauce has beautifully thickened and all the ingredients are heated through. Serve immediately and get ready to enjoy!

How to Serve Your Delicious Skillet Chicken Fajitas

These versatile chicken fajitas can be enjoyed in a variety of ways, making them perfect for any meal or dietary preference. The classic way to serve them is as tacos, nestled in warm corn or flour tortillas. For a lighter, low-carb option, consider serving them in crisp lettuce wraps.

Elevate your fajita experience with an array of delicious toppings! We love ours with a dollop of creamy sour cream, a spoonful of fresh salsa (or a spicy homemade version), and rich, chunky guacamole. Don’t forget a squeeze of fresh lime juice to brighten all the flavors!

Perfect Pairings: What to Serve with Fajitas

Round out your fajita feast with these fantastic side dishes that perfectly complement the vibrant flavors:

• Arroz Rojo (Mexican Red Rice): A classic and essential pairing, this fluffy, flavorful rice soaks up all the delicious juices.
• Frijoles Refritos (Mexican Refried Beans): Creamy, savory refried beans are a must-have for an authentic Mexican meal.
• Instant Pot Buttery White Rice: A simple, comforting rice option that provides a neutral base for the fajita flavors.
• Simple Instant Pot Pinto Beans: Hearty and wholesome, these beans are easy to make and wonderfully satisfying.
• Arroz Verde Poblano: For a different rice experience, this green rice offers a fresh, herbaceous flavor with a hint of poblano spice.

If you are following a Whole30 program, here are some additional serving suggestions to keep your meal compliant and delicious:

• Serve the fajita mixture generously in crisp lettuce wraps.
• Pile it high on top of a fresh, green salad for a hearty and healthy bowl.
• Enjoy it alongside a perfectly baked potato or sweet potato, a comforting and compliant side.

Storing and Reheating Your Skillet Chicken Fajitas

One of the best things about these chicken fajitas is that they often taste even better the next day as the flavors continue to meld! Store any leftovers in an airtight container in the refrigerator for up to 3 days. For longer storage, these fajitas freeze beautifully for up to 6 months. Simply transfer the cooled mixture to a freezer-safe bag or container.

To reheat, you have a couple of options: Warm them in the microwave for 2-4 minutes, stirring halfway through, until heated through. Alternatively, for a crisper texture, place them back on a skillet over medium heat, stirring occasionally until thoroughly warmed. Add a splash of water or broth if the mixture seems dry.

Expert Tips & Creative Variations for Your Fajitas

Maximize the flavor and versatility of your skillet chicken fajitas with these handy tips and exciting variations:

• Whole30 Compliance Check: If you’re adhering to Whole30 guidelines, ensure you specifically use arrowroot or tapioca powder for the chicken coating. Additionally, always opt for Whole30-approved cooking oils such as avocado oil or light olive oil. Double-check all sauce ingredients for hidden sugars or non-compliant additives.
• Skillet Alternatives: While a cast-iron skillet is ideal for its superior heat retention and ability to create a beautiful char, don’t worry if you don’t own one. A regular heavy-bottomed pan or even a Dutch oven will work perfectly well for cooking these fajitas. Just ensure your pan is large enough to avoid overcrowding.
• Boost Your Veggies: Fajitas are incredibly adaptable to various vegetables. Feel free to add other favorites like sliced mushrooms for an earthy touch, zucchini for added freshness, roasted poblano peppers for mild heat and smoky flavor, or jalapeño peppers if you desire an extra spicy kick. Get creative with what’s in season!
• Chicken Fajitas on the Blackstone Griddle: If you’re lucky enough to own a Blackstone griddle or similar flat-top grill, this recipe is perfect for it! The large surface area allows you to cook the chicken and all the vegetables simultaneously in separate zones, achieving fantastic searing and charring on everything at once. This method is excellent for feeding a crowd and making quick work of the cooking process.
• Perfect Chicken Slicing: For tender, evenly cooked chicken strips, cut the chicken breasts against the grain. This shortens the muscle fibers, resulting in a more tender bite. Aim for strips that are about ¼ to ½ inch thick.
• Don’t Overcrowd the Pan: This tip is worth repeating! When searing the chicken, cook in batches to ensure each piece gets direct contact with the hot surface. Overcrowding leads to steaming, not searing, and you’ll miss out on that delicious crispy crust.
