Juicy chicken and veggies steeped in Tex-Mex spices, begging to be piled high in warm tortillas.

Ingredients

1½ lbs boneless, skinless chicken breasts
3 bell peppers (red, yellow, green), sliced
1 large onion, sliced
1 (14.5 oz) can diced tomatoes, drained
2 cloves garlic, minced
1 tablespoon chili powder
1 teaspoon ground cumin
1 teaspoon paprika
½ teaspoon dried oregano
Salt and black pepper, to taste
Juice of 1 lime
Fresh cilantro, for garnish
Tortillas and your choice of toppings, for serving (sour cream, guacamole, shredded cheese, pico de gallo, etc.)

Directions

Prepare the Vegetables:
Layer the sliced onions and bell peppers evenly at the bottom of your slow cooker. This step helps to create a base, keeps the chicken elevated, and ensures even veggie cooking.

Add Chicken and Seasonings:
Arrange the chicken breasts on top of the veggies. Sprinkle the chili powder, cumin, paprika, oregano, minced garlic, salt, and pepper directly onto the chicken. This way, all the zesty flavors will seep into the meat as it cooks.

Add Tomatoes and Lime Juice:
Pour the drained diced tomatoes over the seasoned chicken and squeeze the juice of one lime for a citrusy zing that brightens all the Tex-Mex spices.

Cook:
Cover and cook on low for 6 hours or high for 3 hours. The chicken should become so tender it practically falls apart. No need to fuss—just set it and forget it!

Shred and Mix:
Once cooked, use two forks to shred the chicken right in the crockpot. Stir the shredded meat together with the veggies and all those luscious juices for an even flavor distribution.

Serve:
Spoon generous portions of the fajita mixture into warm tortillas. Top with fresh cilantro and add any extra toppings you love, such as sour cream, guacamole, shredded cheese, or salsa. Serve hot and enjoy!

Top Tips for Perfecting Crockpot Chicken Fajitas

Use boneless, skinless thighs instead of breasts for an even juicier fajita filling.
Try swapping in other veggies like mushrooms or zucchini for added nutrition and color.
Don’t skip thawing the chicken if using frozen—it ensures even cooking and food safety.
Add cheese or sour cream just before serving to prevent sogginess.
For a lower-carb option, serve with lettuce wraps or over cauliflower rice.
To adjust spice levels, add a pinch of cayenne or use fire-roasted diced tomatoes.

Storing and Reheating Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. Ensure the fajita filling cools completely before covering to prevent condensation and sogginess. To reheat, simply warm the chicken and veggies on the stove over medium heat until hot throughout, or microwave individual portions for 1–2 minutes. For longer storage, freeze the fajita mixture in a freezer-safe bag or container for up to 3 months—just thaw overnight in the fridge before reheating. Always add fresh toppings and tortillas just before serving for best taste and texture.
