The Easiest Fajita Recipe!

This crockpot chicken fajita recipe is seriously a one pot, set it and forget it recipe! You’ll place all your ingredients in the crockpot (including this flavorful homemade fajita seasoning!) and cook on high for 2 hours or low for 6 hours, and voila! Chicken fajitas are served! If you’re looking for an easy weeknight din, this is it!

How to Prepare Chicken Fajitas

The key to getting the tender, perfectly cooked chicken for this recipe is to cook the breasts WHOLE in your crockpot before taking the cooked breasts out and slicing fajita-style right before serving. We tested this recipe slicing the chicken raw and then cooking, but the chicken was over-cooked and tough.

This method also allows the fajita veggies to cook perfectly in the same amount of time as the meat. Nobody wants overcooked, mushy fajita veggies!

Toppings for Fajitas

Now that you’ve got the perfectly prepared chicken fajitas, let’s talk toppings! Feel free to make this recipe your own, and add your favorite fajita toppings. You’ll find us serving our crockpot chicken fajitas with the following (depending on what we have on hand):

Shredded cheese or crumbled cotija
Lettuce or cabbage
Greek yogurt
Diced onion
Diced tomato
Cilantro
Sliced avocado or guacamole
Salsa
Squeeze of lime juice

How to Serve Fajitas

No need to stick with the traditional hard or soft shell taco if you’re looking for a low carb or GF option instead! These crockpot chicken fajitas are great in so many different ways, like:

In a soft shell: we love flour, corn and Siete’s cassava flour soft shells!

In a hard shell: Siete also makes a hard shell taco shell that we love. Otherwise, you’ll find us grabbing the traditional hard shell corn tortilla.

As nachos: Whip up a batch of nachos in the oven and top with your favorite fajita toppings. Or try these cauliflower nachos if you want to go sans chips!

In a lettuce wrap: We love using romaine hearts or cabbage leaves for a delicious and low carb lettuce wrap fajita!

As a salad: Who doesn’t love a chicken fajita salad?! Simply put fajita veggies + the fajita chicken over a bed of lettuce, and you’re on your way to a delicious fajita salad.
