Simple Crockpot Chicken Fajita Ingredients

  • Bell Peppers – Red, yellow, orange, green or any colors will work.
  • Onion and Fresh Garlic – Use any color onion that you have on hand (yellow, white, red, etc.).
  • Salsa – Or a can of diced tomatoes with green chilies (such as original Rotel®).
  • Boneless Skinless Chicken Breasts – Leave them whole so they don't over cook.
  • Fajita Seasoning – Use a store bought blend or homemade.
  • Tortillas – Flour or corn tortillas.
  • Toppings/Garnishes – Avocado, hot sauce, tomatoes, sour cream, cilantro, etc.

To get the best tasting crockpot Chicken Fajitas you will need a good fajita seasoning. Here is the recipe for my popular Homemade Fajita Seasoning.

Having fresh bell peppers and onion makes a big difference as well. You can also use frozen bell peppers, but they will release more water and be softer.

These crockpot chicken fajitas will make your house smell so good while they are cooking!

How to Make Slow Cooker Chicken Fajitas

1) Add half of the veggies to the crockpot.
2) Add the whole chicken breasts and cover with the fajita seasoning (Use store bought or homemade).
3) Pour the salsa over the seasoned chicken breasts.
4) Top with the remaining vegetables, cover, and cook.

Serving Crockpot Fajitas

  • Gather all of your garnishes and toppings. Sour cream, salsa, chopped tomatoes, sliced avocados or guacamole, Mexican hot sauce.
  • After cooking, use a slotted spoon to transfer the mixture to a serving platter. Then remove the chicken and slice it.
  • To make a fajita, wrap some of the chicken and vegetables in warmed corn or flour tortillas, add lots of yummy toppings, and have a feast!
  • Serve chicken fajitas over a bowl of rice or quinoa to make a burrito bowl.

Tips And Variations

  • If you prefer the bell peppers crisp, and not too soft, wait to add them to the crockpot until the last 40 minutes of cook time.
  • Store leftovers in the fridge for up to 3 days.
  • This easy fajitas recipe makes a nice amount, and will easily feed a family of 3 or 4. You can sneak another chicken breast in there to make more servings, if you want to.
