Step‑by‑Step Instructions for Low Carb Chicken Fajitas
Step 1: Gather Ingredients and Tools
Begin by assembling all your ingredients for the Low Carb Chicken Fajitas. You’ll need chicken breasts, bell peppers, onion, and spices, along with olive oil. Preheat your skillet over medium-high heat for optimal cooking. Having everything in place will make the process smooth and enjoyable, ensuring you can focus on crafting a delicious meal!
Step 2: Prepare the Fajita Spice Mixture
In a small bowl, combine the chili powder, smoked paprika, onion powder, garlic powder, kosher salt, cumin powder, and cayenne pepper. Mix well to create your homemade fajita seasoning. This flavorful blend will enhance your chicken and veggies, giving them an aromatic touch. Set this spice mix aside, as you will coat the chicken with it shortly.
Step 3: Slice the Chicken and Coat with Spice
Slice your chicken breasts into uniform ¼-inch strips for even cooking. In a large bowl, toss these strips with the fajita spice mix until they are well-coated. This step enhances the flavor profile, ensuring every bite of your Low Carb Chicken Fajitas is packed with deliciousness. Once well-coated, set the chicken aside for a few minutes while preparing your skillet.
Step 4: Cook the Chicken
Add a tablespoon of olive oil to your preheated skillet, swirling it to coat the bottom. Carefully add the coated chicken strips and let them cook undisturbed for about 6-8 minutes. You’ll know they’re done when they turn golden brown and no longer pink in the center. Once fully cooked, remove the chicken from the skillet and set aside, allowing it to rest while you prepare the vegetables.
Step 5: Sauté the Vegetables
In the same skillet, deglaze by adding a pinch of water to scrape off flavorful bits, then add another tablespoon of olive oil. Toss in sliced onions and bell peppers, sautéing them for 8-10 minutes until they soften but still retain some crispness. The vibrant colors and aromas will fill your kitchen, adding to the excitement of your Low Carb Chicken Fajitas!
Step 6: Combine Chicken and Vegetables
Once the vegetables have reached their desired tenderness, return the cooked chicken to the skillet. Stir them together gently to mix the flavors, ensuring the chicken is well integrated with the sautéed onions and peppers. Allow this mixture to heat through for an additional 2-3 minutes, letting those delicious flavors meld perfectly.
Step 7: Serve and Enjoy
Transfer your savory Low Carb Chicken Fajitas to a serving plate. Add any optional toppings such as guacamole or a drizzle of chipotle sauce for extra flavor. Feel free to get creative with your presentation to delight your family or guests. Enjoy the vibrant taste of your homemade fajitas while celebrating the satisfaction of a homemade meal!

Make Ahead Options
These Low Carb Chicken Fajitas are ideal for meal prep and can save you precious time during busy weeknights!

When it's time to cook, just heat your skillet and sauté the chicken first, followed by the prepped veggies for a quick and delicious meal. With this prep method, you’ll still enjoy those vibrant flavors and textures, making dinner both effortless and satisfying!
