Our family LOVES the flavor profile of Mexican dishes, so it’s no surprise that they vanish quickly when chicken fajitas are being served.

I mean, what’s not to love? Tender, juicy slices of chicken breasts, multicolored bell peppers, and onions seasoned with bold fajita flavor come together for one scrumptious meal. 

There is no need to visit a Mexican restaurant and risk messing up your low-carb diet with traditional fajitas when you can have Mexican food at home.

The problem is that to keep the recipe low in carbs, and keto-friendly, we need to start with the right seasoning and ensure it’s accompanied by sides that keep our keto macros in check.

Are Chicken Fajitas Keto-Friendly?

Chicken fajitas can be keto-friendly as long as you season them with homemade sugar-free fajita seasoning, and they are served with keto tortillas, cauliflower rice, or wrapped in lettuce.

What’s key to keeping them low in carbs is not serving them with traditional tortillas but with low-carb tortillas. Nor should you accompany them with refried beans.

Chicken fajitas can be a healthy, delicious option; while doing a ketogenic diet, leave out the high-carb sides, and you’ll be good.

Not a fan of chicken breasts? No problem; you can substitute it for skinless, boneless chicken thighs. Just keep in mind that it will need to be cooked a tad longer.

Once your chicken breasts are sliced and generously tossed with our keto-friendly fajitas seasoning and lime juice for rich Mexican flavors, you can marinate the chicken ahead of time or the day of. Either way, the keto fajitas will be full of flavor.

The chicken strips are cooked over medium-high heat in a large skillet that is lightly coated with your choice of oil, where they get seared.

I then sauteed a combination of sliced red, orange, yellow, and green bell peppers and onions in the skillet the chicken fajitas were cooked in.

The vegetables can get slightly charred around the edges to caramelize in the chicken’s juices. Then it’s just a matter of serving with keto side dishes.

You can keep things even easier by serving the chicken fajitas with low-carb wraps and not bothering to make any of the sides.
