Crockpot chicken fajitas are easy to make in your slow cooker with juicy chicken, bell peppers, onion and taco seasoning. A simple slow cooker dinner that everyone will love.
Crockpot Chicken Fajita Recipe
Crockpot chicken fajitas are an easier version of the traditional fajitas that you’d find sizzling in a skillet! Much like sheet pan chicken fajitas, it has the same delicious flavors, with tender strips of chicken, peppers, and onions, but in a simplified hassle-free meal.
Much like my slow cooker chicken taco bowls, and slow cooker chicken tinga tacos the crockpot does most of the work in this recipe. Cook it on low and you’ve got a meal to come home to that’s ready to serve a hungry crowd!
Ingredient Notes
Find the full printable recipe with specific measurements below.
- Chicken breasts: Boneless skinless chicken breasts. Keep them whole until they’re cooked.
- Taco seasoning: Use either fajita seasoning or taco seasoning as both will deliver loads of flavor.
- Salt & pepper: Just a little extra seasoning to taste.
- Diced tomatoes: I use the petite diced tomatoes with green chiles (Rotel). Use mild or hot, it’s up to you or use plain diced tomatoes.
- Red onion: Thinly sliced red onions are a popular component of traditional fajita veggies. You can use white onion or yellow onion if preferred.
- Bell peppers: Use whatever color bell peppers you prefer. The savory sweet of both red and green peppers is a nice pairing.
- Lime juice: Freshly squeezed from 1 lime gets added to the juices at the end. It adds a zesty bright element that can’t be missed.
- For serving: My favorites include flour tortillas, shredded cheese, sour cream, pico de gallo and guacamole. Sometimes I make a chicken fajitas bowl with rice.
How to Make Crockpot Chicken Fajitas
- Add chicken to the basin. Place the meat in the basin of the slow cooker. Sprinkle the taco seasoning, salt and pepper overtop. Then add the tomatoes, onion, and garlic. Stir everything to combine, making sure the chicken is well coated.
- Cover and cook. Add the lid to the crockpot and cook on high for 2-3 hours or on low for 4-6 hours until the chicken is cooked through. Add the bell peppers 30 minutes before the cooking time is over. You can add them to the mixture earlier if you don’t mind very soft veggies.
- Slice or shred the meat. Once the chicken is cooked, transfer the breasts to a cutting board. Allow it to rest for a few minutes and then slice them or use two forks to shred them apart. Remove 1 cup of liquid from the pot and discard it. This is so too much liquid doesn’t start to dilute the flavors. Return the chicken to the pot.
- Serve and enjoy. Stir in fresh lime juice and season the fajita mixture with salt and pepper. Serve crockpot chicken fajitas warm in flour or corn tortillas and pile on your favorite fajita toppings!
Recipe Tips
- Slicing vs shredding. To make shredded chicken you’ll need it to be fall-apart tender. This happens when you cook the chicken closer to the max cooking times. On high for 3 hours (as opposed to 2) or on low for 6 hours (as opposed to 4).
- Swap the breasts for chicken thighs. They will cook faster and fall apart easier, so this is a great choice if you want shredded chicken.
- Frozen chicken. Will need to be thawed first. Slow-cooking frozen meat allows it to spend too much time at unsafe temperatures giving way to bacteria spreading.
- Slow cooking needs liquid. The juices from the canned tomatoes add liquid to the recipe which adds moisture to the chicken and prevents it from burning.
- Add-ins: After chicken is shredded, add layer of cheese to cover like in my fajita chicken casserole or stir in some heavy cream like I do in chicken fajita pasta.
Meal Prep and Storage
- Store: Leftovers of crockpot chicken fajitas can be kept in an airtight container for up to 4 days in the fridge. You can also freeze it up to 3 months.
- Meal prep: Portion them out into smaller containers for easy meals throughout the week. Take some for lunch one day and have leftovers for dinner another day.
- Reheat: To reheat the fajitas, use the microwave. If you want to use the oven or a skillet to crisp them a bit you can. The air fryer would also do the trick.
