No need to go out to dinner just to have a sizzling hot plate of chicken fajitas, you can get the same flavor from home with this easy recipe – just make everything in a sheet pan! For this keto Mexican recipe, we only use a few simple ingredients that you probably already have in your pantry. All you might need to get are chicken thighs, bell peppers and an onion. This recipe for sheet pan fajitas delivers that same char-broiled taste without the need for open flame! The best part is that these keto chicken fajitas cook in minutes so you can have a healthy dinner on the table in less than 30 minutes.

I love to enjoy these sheet pan chicken fajitas by themselves and topped with lime and cilantro, but they are excellent over cauliflower rice (especially Mexican Cauliflower Rice) and low carb tortillas. Top with sour cream, fresh cilantro, lime juice or sliced avocado.

Broil vs Bake

If you have made sheet pan fajitas before or you have looked at other recipes, you may have noticed that they are baked in the oven. This recipe for chicken fajitas is different. We BROIL the keto fajitas instead of baking them. The benefit of broiling this sheet pan dinner is two-fold. First, the chicken fajitas cook faster since they are cooking over a high heat. Second, broiling fajitas chars them instead of steaming or baking them. You get char broiled flavor from the peppers, onions and chicken.

Types of Chicken

In this keto fajita recipe, I used skinless, boneless chicken thighs. I prefer chicken thighs over chicken breasts because they have more flavor thanks to their higher fat content. Chicken thighs are also less expensive compared to chicken breast but with this easy keto sheet pan dinner, you can use either light or dark meat.

Low Carb Tortillas

If you want to make true fajitas with the tortillas, there are a couple different types of keto tortillas you can choose from. You can make your own keto tortillas with almond flour or you can make tortillas with coconut flour.  You can even buy low carb tortillas from the store. This is the more convenient option. Either way, these options are the perfect cover for your sheet pan chicken fajitas.

Some options of low carb tortillas that you can use are:

  • Mission Carb Balance: These low carb flour tortillas are the closest to real tortillas and are available at most major grocery stores; however, they contain gluten. So if you are avoiding gluten for sensitivities or inflammation, it’s best to avoid these tortillas
  • Untortillas: Unbun makes a gluten free tortilla that has a nice flavor. They are grain free and roll without cracking.
  • Egglife: These tortillas are made from eggs. These are a great option if you are avoid nuts and gluten.
