Keto Authentic Chicken Fajitas – Fajitas de Pollo

Keto Authentic Chicken Fajitas are so quick to make and so delicious. They are sizzling to perfection, go well with guacamole, and are perfect in keto almond flour tortillas. They feature seasoned chicken breasts with the perfect amount of tri-colored bell peppers and sautéed onions. Joanie’s recipe is made in one hot skillet and can go from stove-top to table in 15 minutes. Your whole family will love this authentic recipe.

We love Mexican food! Since we live in the Southwestern part of our country, that should not be a surprise. Virtually every Mexican restaurant offers a plethora of delicious meals; however, many are accompanied by rice and beans. Not very low carb, to say the least! Trying to avoid the tortilla chips served with delicious salsas and cheese dips is hard enough. Our go-to low carb choice at most Mexican restaurants – fajitas. Whether chicken, shrimp, beef or a combination, we know they will be delicious and low in carbs.

Here are few of our other Mexican recipes that will go well with your fajitas:

  • Margarita – Classic and Low Carb

    Cooks in 5 minutesDifficulty: Easy

  • Keto Chicken Tortilla Soup

    Cooks in 45 minutesDifficulty: Easy

    Keto Chicken Tortilla Soup is the perfect low-carb soup with the right spices, a little heat, and packed with shredded chicken. Top it with chopped avocado, cilantro, and Queso Fresco!

  • Keto Albóndigas (Meatball) Soup

    Cooks in 60 minutesDifficulty: Medium

    Keto Albóndigas Soup, a classic Mexican recipe. A delicious stock with lots of vegetables for flavor – and a bit of a kick!


The fajita seasoning is the key to this recipe. Joanie makes her own and uses a blend of Mexican spices. Use cumin, chili powder, and smoked paprika – they are very important to the recipe. Also, do not skip the fresh lime juice – it works so well with the chicken. A lot of recipes do not coat their vegetable strips with fajita seasoning. We like the fajita taste throughout the dish so Joanie will separate the marinade and use half for the vegetables and half for the chicken. You can certainly use this same marinade with chicken, shrimp, or beef or any combination of the three that you prefer.

We usually serve our Keto Authentic Chicken Fajitas on a plate. Probably a habit we began when we wanted to avoid carb-laden tortillas at our favorite Mexican restaurant. However, feel free to use our Keto Almond Flour Tortillas for serving. Each tortilla has only 3g of net carbs and they are delicious.

Preparation Tips

As I mentioned above, Joanie likes to make sure our vegetables also have that delicious fajita seasoned taste. To accomplish this she will place them in a separate zip lock bag with seasoning, just like we do with the chicken strips. The flavors will then permeate the entire dish and be enjoyable in each bite. We also stress that the vegetables and chicken should be at room temperature before cooking. The secret to moist and juicy chicken is to cook at high heat. You can maintain that heat level in your skillet when you sear room-temperature chicken.

Joanie used our cast iron skillet for this recipe. Even on medium-high heat, it will get very hot and require moving the chicken and vegetables a lot during the cooking process. Do this to avoid sticking and burning. As a reward, you will have tender chicken and can serve the fajitas right in the skillet for a sizzling presentation.
