These easy chicken fajitas are healthy, packed with flavor, and perfect for a quick weeknight dinner. The chicken is juicy and perfectly seasoned with a homemade fajita spice blend, then seared with crisp-tender bell peppers and onions for that bold, sizzling flavor you love. Wrap it all up in warm low carb tortillas and top with your favorite fixings for a meal that’s better than takeout — and ready in 30 minutes!
In a large bowl, combine the sliced chicken with 1 tablespoon olive oil, lemon or lime juice, and all the fajita seasoning spices. Toss to coat evenly. Cover and refrigerate for at least 30 minutes to let the flavors soak in.
While the chicken marinates, slice your onion and bell peppers into long, even strips.
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the peppers and onions and sauté for 4–6 minutes, until slightly softened but still crisp-tender. Remove from the pan and set aside.
In the same skillet, add the marinated chicken. Cook for 5–10 minutes, stirring occasionally, until fully cooked and no longer pink.
Return the peppers and onions to the pan with the chicken. Toss everything together and cook for another 2 minutes so the flavors meld.
Serve hot over warm low carb tortillas and load up with your favorite toppings!
