Best Crockpot Fajitas

  • Everyone loves fajitas, especially the grand production of presenting them, sizzling and steaming, fresh from the kitchen. The difference is that these crockpot fajitas are made without all the fuss and muss of stovetop cooking. Just ‘set it and forget it’ while enjoying some time to prepare other things, like Texas Caviar or a side of Mexican Corn Salad.
  • Cooked long and slow in the crockpot, these chicken breasts will absorb the fajita spice and all the yummy juices of the peppers and onions. 
  • What’s more, is that all the ingredients in this recipe are so healthy (and low carb).  
  • These chicken fajitas are delicious served with some homemade salsa, and then topped with shredded cheese. Use the chicken to top a caesar salad, or add them to a tortilla with some cheese, black beans, and salsa for a filling wrap.

Ingredients & Variations

CHICKEN Choose boneless, skinless chicken breasts for this recipe. Fresh or frozen breasts will do. Slice the chicken into strips. 

FAJITA SPICE Fajita spice is a combination of cayenne pepper, paprika, sugar, chili powder, cayenne, cumin, garlic, and more. It has a bit of spicy kick to it. Pre-mixed fajita can easily be found in the Mexican section of the supermarket. The breasts can also be seasoned with taco seasoning. 

THE VEGETABLES It seems like all the colors of the pepper world are added to this chicken dish – red, green, and yellow. Remember to slice them into strips and layer them on top of the chicken. 

VARIATIONS After the chicken has cooked, make a plate of sauteed mushrooms, shredded lettuce, diced tomatoes, sliced black olives or cucumbers, jalapenos. Make another plate of shredded Monterey Jack, cheddar cheese, or crumbled cotija cheese. Make some refried beans or black beans. Add a plate of salsa, sour cream, and guacamole. Place all of these out on the table with some tortillas and everyone can make their own wraps.

    1. We haven’t doubled this recipe but it shouldn’t affect the cooking time. Just be sure to check your chicken to make sure it is fully cooked before serving!

    1. We’ve only made the recipe as directed but that shouldn’t be a problem. Let us know how it turns out Sandy!

    1. The ingredients call for 1 green bell pepper, 1 yellow bell pepper and 1 red bell pepper. Enjoy Kay!

    1. I haven’t tried it with frozen chicken. According to Crock Pot, frozen or partially frozen foods require a longer cook time in a slow cooker than the recipe indicates for a stovetop or oven. Using an instant read thermometer is recommended to ensure meat is cooked through and tender. Frozen meats can be cooked in a slow cooker, however, it is best to use the following guidelines: Add at least 1 cup of warm liquid to the stoneware before placing meat in the stoneware. Do not preheat the slow cooker. Cook recipes containing frozen meats for an additional 4 to 6 hours on low, or an additional 2 hours on high.

    1. While I have only tried it as written, you can usually convert 4-6 hours on low to 1 1/2 – 2 1/2 hours on high.

  1. These recipes look and sound absolutely delicious. Plus they look easy to fix. Im ALL about easy and cheap. Looking forward to fixing them.

        1. Amanda, I usually slice the chicken about in about 1/4 inch slices. It’s a little thicker slices than the pepper usually. The exact size isn’t critical to this recipe. Enjoy the Fajitas!!
