For the Fajitas
  • 1.5 lbs chicken breast boneless, skinless, sliced into 1/2-inch strips

  • 1 large onion thinly sliced
  • 1/4 cup chicken broth
  • 2 tbsp lime juice freshly squeezed
  • 1 tbsp olive oil
Homemade Fajita Seasoning
  • 2 tsp chili powder
  • 1.5 tsp cumin ground
  • 1 tsp paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/2 tsp dried oregano
  • 1/2 tsp cayenne pepper optional, for heat
  • 1 tsp salt or to taste
  • 1/2 tsp black pepper freshly ground
For Serving
  • 12 flour tortillas warm
  • 1 cup salsa
  • 1/2 cup sour cream
  • 2 avocado ripe, sliced or guacamole
  • 1/4 cup cilantro fresh, chopped

Equipment

  • Slow Cooker (6-quart or larger)
  • Mixing Bowl
  • Cutting Board
  • Sharp Knife

Method
 

Prepare the Seasoning
  • In a small bowl, combine chili powder, ground cumin, paprika, garlic powder, onion powder, dried oregano, cayenne pepper (if using), salt, and black pepper. Mix well.
Combine Ingredients
  • Place the sliced chicken strips, bell peppers, and onion into the crockpot. Drizzle with olive oil and fresh lime juice. Sprinkle the homemade fajita seasoning evenly over all ingredients. Pour in the chicken broth.
Cook in Crockpot
  • Stir everything gently to ensure all ingredients are coated with the seasoning. Cover the crockpot and cook on HIGH for 3-4 hours or on LOW for 6-8 hours, until the chicken is cooked through and easily shredded, and the vegetables are tender.
Shred Chicken (if using)
  • Once cooked, remove the chicken strips from the crockpot and shred them using two forks. Return the shredded chicken to the crockpot and stir to combine with the vegetables and juices.
Serve
  • Serve the Crockpot Fajitas warm in warm flour tortillas with your favorite toppings like salsa, sour cream, sliced avocado or guacamole, and fresh chopped cilantro.

Notes

For a spicier kick, add an extra pinch of cayenne pepper or a sliced jalapeño to the crockpot along with the other ingredients. This recipe can also be made with beef strips (flank or skirt steak), though cooking times might vary slightly. Store leftovers in an airtight container in the refrigerator for up to 3-4 days.

How I Make Crockpot Fajitas

Making these Crockpot Fajitas is wonderfully straightforward. I whisk together my seasoning, then toss the chicken, bell peppers, onion, broth, lime, and olive oil right into the crockpot. It slow cooks to perfection, filling my home with an irresistible aroma. Once done, I sometimes shred the chicken. It’s a fuss-free way to achieve incredible flavor, much like my slow cooker jambalaya.

My Tips for the Perfect Outcome

  • Don’t skip the lime juice – it brightens all the flavors.
  • Slice your veggies uniformly for even cooking in these Crockpot Fajitas.
  • Resist the urge to peek too often; let the crockpot do its work.
  • For extra heat, a pinch more cayenne pepper is always a good idea!

Serving Suggestions and Storage Tips

I love serving my Crockpot Fajitas with warm flour tortillas, fresh salsa, cool sour cream, creamy avocado, and cilantro – a customizable feast! Leftovers are fantastic. Store any extra fajita mixture in an airtight container in the refrigerator for up to 3-4 days; it reheats beautifully. Another comforting make-ahead option? My crockpot chicken and dumplings.

FAQs

faq 1

Can I use frozen chicken breast for this recipe? While fresh is always best for texture, you can use frozen chicken breast. However, you’ll need to increase the cooking time slightly to ensure it’s cooked through. Make sure to cut the chicken into uniform strips before adding it to the crockpot for even cooking, or shred it once it’s tender.

faq 2

What kind of bell peppers work best for Crockpot Fajitas? I prefer a mix of red, yellow, and orange bell peppers for visual appeal and a sweeter flavor profile. Green bell peppers are also fine, but they tend to be a bit more bitter. Whatever colors you choose, slice them uniformly so they cook down evenly and beautifully in the crockpot.

faq 3

Can I make these Crockpot Fajitas spicier? Absolutely! If you love a little extra kick, I recommend increasing the amount of cayenne pepper in the seasoning blend. You could also add a pinch of red pepper flakes to the crockpot, or serve the finished fajitas with a fiery hot sauce for an added punch. Adjust to your personal heat preference!

faq 4

What are some good alternatives to tortillas for serving? If you’re looking for an alternative to tortillas, these Crockpot Fajitas are incredibly versatile. I love serving them over a bed of fluffy rice or quinoa. They also make a fantastic filling for lettuce wraps for a low-carb option, or piled high on a crispy salad. So many delicious possibilities!

This recipe holds a special place in my heart, and I truly hope it brings as much joy to your table as it does to mine. If you try it, I’d absolutely love to hear what you think! For more delicious Crockpot Recipes, like my comforting slow cooker Korean beef, I’m always sharing new ideas.
