Keto Fajitas with steak, onion and bell pepper in cast iron
I understand no one asked but I love Mexican food! Really, anything with a Spanish heritage down to the women. The culture has fascinated me for years leading to Spanish being almost my second language. Not fluent yet but nor am I a beginner. Anyway, more about the food! Making keto fajitas with chicken or steak is super easy. Sear it beautifully then sauté the veggies, that’s it. I am currently working on a Mexican cauliflower rice to pair with this so follow on Pinterest to keep up to date!

What Kind Of Steak For Fajitas

Flank or skirt steak would be the best options. Traditionally, I believe the recipe is made with flank steak. I prefer the extra fat and marbling that comes with skirt so I normally take that route.

What Is In Fajita Seasoning

Traditional spices are easily chili powder and cumin. There are many other variations but for a classic flavor you have to combine the two. Not one or the other you have to have both for that true Mexican feel.

How To Make Keto Fajitas With Steak Or Chicken

To start, you want to make a marinade for the steak or chicken. Overnight is great but we all don’t have that sort of time or memory. Marinating for 15 minutes is good and the flavor is still great. In a small bowl, make the spice blend. Save a little for the bell peppers and onions though.

Now, when meat is done marinating you are ready to cook. Slice up your vegetables and get your pan out. Cast iron is the best for this recipe.

On high heat, add a little oil and your veggies. Sauté these to tender not mushy. Move quick because the pan is hot. If it gets too smoky drop the temp a little. Remove bell peppers and onions when they are done.

You may need to add a little more oil, just check. Next, add in marinated steak. Get a good sear on both sides and cook to ideal temp. I go for medium temperature steak (not pictured) but whatever you like is fine.

Once steak is cooked then you’re done. Serve with cilantro lime cauliflower rice or keto tortillas. As mentioned, I am working on a Mexican cauliflower rice so stay tuned for that.

Helpful Recipe Tips

  • Sauté veggies first, I have done this a few times and this is the best method. You can do it in reverse but those dark bits that fall off the steak while searing will be all over your vegetables. It’s not a hard rule but something to note.
  • Slicing steak, be sure when using skirt or flank steak you cut against the grain. Otherwise, the steak tenders will be very tough and chewy due to you not cutting against them. How to cut against the grain? Think of a “x” or cross. Look for the lines in the meat and go in the opposite direction when cutting.

  • Cover the steak or chicken in the marinade then cover. Overnight is great but 15 minutes will do. When using chicken be sure to use thin chicken.
  • Slice up both bell peppers and onions for cooking. When meat is done marinating start the cooking process.

  • After vegetables are done remove them from pan. Turn heat to high and cook and sear the marinated steak until your ideal done temperature. If using chicken, make sure chicken is thin and don't turn up the heat to cook it.
  • At this point you are finished and reasy to serve.
