Although it’s no secret that our family loves Mexican dishes, keeping things Mexican and keto can be a bit of a challenge; in order to keep the shrimp fajitas keto-friendly, I make sure to use our homemade seasoning mix.

This way, I know exactly what’s in it and can be sure there are no hidden ingredients that could kick us out of ketosis.

Are Shrimp Fajitas Keto-Friendly?

Shrimp fajitas can be keto as long as you season them properly and then accompany them with keto tortillas, cauliflower rice, or wrap them in lettuce. Mind those sides, and you’ll be in the safe zone.

And by all means, be sure to drizzle your shrimp fajitas with our keto spicy cilantro garlic sauce for a zesty kick! Rest assured that you can enjoy shrimp fajitas with tortillas.

In fact, there are now many low-carb tortilla options on the market. Do keep in mind that many of those have wheat in them and are not gluten-free.

I serve my keto fajitas with my homemade, egg-free tortillas which are delicious and pliable. Plus, they are super easy to make. I roll my low-carb tortillas between parchment paper for the perfect thinness. 

I say all that to say that you could also just serve the seasoned shrimp and veggies on top of a green salad and eat with a fork.

You know, like shrimp fajita bowls! No matter how you decide to eat it, it will be a tasty keto meal!

How To Make Keto Shrimp Fajitas

There is no need to marinate the shrimp with the seasoning and lime ahead of time. In fact, I recommend that you season right before cooking because the addition of lime juice could “cook” the shrimp, similar to what happens in ceviche.

Once your shrimp have been deveined and the tails removed, you will toss them with our keto fajitas seasoning and lime juice.

Then, the shrimp, along with the veggies, are cooked over medium-high heat in a large skillet that is lightly coated with avocado or refined coconut oil.

My vegetables of choice were a combination of sliced red, orange, yellow, and green bell peppers, as well as yellow onions.
