- 2 ½ pounds chicken breast
- 2 ½ teaspoons garlic powder
- 2 teaspoons chili powder
- 1 teaspoon kosher salt

- ¼ teaspoon dried oregano
- 1 (10-ounce) can fire-roasted diced tomatoes with green chilies

How to Make Crockpot Chicken Fajitas
Start by seasoning your chicken well on both sides. Use garlic powder, chili powder, salt, onion powder, cumin, black pepper, smoked paprika, and oregano — these spices build the base flavor. Lay the chicken in the slow cooker and pour the can of fire-roasted diced tomatoes with green chilies right over it. Stir lightly to combine, then cover and cook on low for 5 hours or high for 3 hours.
Once the chicken is nearly cooked, add your sliced bell peppers and onions into the crockpot. Let everything cook together for another 45 minutes. If you want your peppers and onions crisper, reduce this time to about 30 minutes.
When the cooking is done, remove the chicken with a slotted spoon and shred it using two forks. Return the shredded chicken to the crockpot, stir in the lime juice for a bright finish, and let the flavors marry for a few more minutes before serving.
How to Serve Your Crockpot Chicken Fajitas
Serving fajitas is as fun as making them. Warm up corn or flour tortillas to wrap the chicken and veggies. Offer a variety of toppings like sour cream, guacamole, shredded cheese, and salsa so everyone can build their own perfect bite. You can also serve these fajitas alongside rice or beans for a heartier meal. A fresh squeeze of lime over the top adds a final zesty kick that brings the dish alive.
Expert Tips for Making the Best Crockpot Chicken Fajitas
To get the juiciest chicken, opt for boneless, skinless chicken breasts or thighs depending on your preference. Thighs will add extra richness and tenderness. For those who like a little heat, add sliced jalapeños or poblano peppers along with the bell peppers.
If you want to boost the smoky flavor, try sprinkling a bit more smoked paprika or add a dash of chipotle powder. Don’t skip the lime juice at the end — it brightens the whole dish and balances the spices perfectly.
When it’s time to shred the chicken, make sure it’s tender enough to pull apart easily. This will make your fajitas more enjoyable and allow the sauce to cling to the meat better.
How to Store Leftover Crockpot Chicken Fajitas
If you have leftovers, store them in an airtight container in the fridge for up to four days. Reheat gently in the microwave or on the stovetop, adding a splash of water or broth if it seems dry. You can also freeze the shredded chicken and vegetables for up to three months. Just thaw in the fridge overnight before reheating.
This makes the recipe perfect for meal prep or easy lunches throughout the week.
Variations to Try with Your Crockpot Chicken Fajitas
Feel free to switch up the vegetables. Use different colored bell peppers or add sliced mushrooms for an earthy twist. If you want to add some crunch, toss in fresh chopped cilantro or diced red onions just before serving.
For a vegetarian version, replace the chicken with firm tofu or large portobello mushrooms, adjusting the cooking time as needed. You can also experiment with different spice blends like adding smoked chili powder or using fresh garlic instead of powder.
Serve your fajitas with different types of tortillas such as whole wheat, gluten-free, or lettuce wraps for a low-carb option.
