Are Steak Fajitas Keto-Friendly?

Steak fajitas can definitely be keto-friendly if you season them with homemade fajita seasoning, and serve them with keto tortillas, cauliflower rice, or wrapped in lettuce or even a bed of greens as a salad.

The key to keeping the carbs low is not serving them with traditional tortillas but with low-carb options. You should also opt out of the refried beans as they have too many carbs.

Keto fajitas can be a delicious keto option even when dining out, just request to leave out the high carb sides, and you’ll be a happy camper.

We like to also ask for extra guacamole for more of the good fat that keeps us satiated longer! Do keep in mind that there will likely be some hidden carbs in the fajita seasoning when ordering from a restaurant. 

How To Make Low Carb Steak Fajitas

Once your steak is sliced and generously tossed with our keto-friendly fajitas seasoning and lime juice for rich Mexican flavors, you can even let it marinate for up to 4 hours if you are looking for a way to save time. 

However, the low-carb fajita seasoning is so rich in flavor that you could also just season it right before cooking. Either way, the keto fajitas will be bursting with flavor.

Cook the strips of steak over medium-high heat in a large skillet that is lightly coated with your choice of oil, I used avocado oil. Cook for just a few minutes on each side, making sure to get a nice sear on the steaks!

I like to then saute the combination of sliced red, orange, yellow, and green bell peppers and onions in the skillet where the steaks were cooked. Once again, making sure to get a nice sear on the peppers and onions!

The peppers become slightly charred around the edges and the onions caramelize in the steak’s juices. Then serve with your choice of low-carb tortillas, lettuce wraps, or a bed of greens, and of course all of the fixings! Guacamole, sour cream, cheese, pico de gallo, or keto salsa are all the classics.

Best Cuts of Steak For Keto Fajitas

If you’re wondering what type of cuts of steak to use for fajitas I’ve got you covered!

The most popular cuts of steak for fajitas are flank and skirt. Both are great choices and are easily sliced into strips and true to the classic dish. 

This doesn’t mean that you can’t use other cuts of steak, in fact, my favorite is to use is ribeye! 

The ribeye is perfect for keto fajitas because it’s a fatty cut that is perfect for a ketogenic diet! The fat is where all the flavor is too! 

If you don’t like a lot of fat on your meat then the flank steak would be the best choice for you. Sirloin tips are also a great option for fajitas!

Often you’ll find at the grocery store certain cuts already labeled as fajita steak which is helpful to identify which to buy.
