The slow cooker is perfect for creating juicy and flavorful dishes that make the whole house smell great, and it’s incredibly easy to use! It’s the ideal kitchen appliance for those days when you just want to set it and forget it.
These crockpot chicken fajitas are the same as my regular chicken fajitas, except made in the slow cooker! They’re the perfect weeknight dinner when you have a busy schedule, or when you want to meal prep for the week ahead. With minimal prepping, you’ll have a delicious meal ready at the end of your day!
Ingredients in Crockpot Chicken Fajitas
- Chicken: 2 ½ pounds of chicken makes about 6 to 8 servings. I used boneless skinless chicken breasts to keep things lean, but you could also use chicken thighs if you prefer.
- Seasonings: I used a combination of garlic powder, chili powder, salt, onion powder, cumin, black pepper, smoked paprika, and oregano.
- Peppers and onion: I used red, orange, and yellow bell peppers for their sweetness and bright color, but you can use green or any combination of colors. I also like to use yellow onion, but you can use white. If you want the fajitas with a kick, substitute 2 jalapeños or 1 poblano for 1 of the bell peppers.
- Tomatoes and green chiles: I used a can of fire-roasted diced tomatoes and green chiles for extra flavor and a hint of spice.
- Lime juice: Topping off the fajitas with lime juice adds some citrus and helps cut the rich flavor from the seasonings. It really makes all the difference.
- All the fix-ins: You can’t have fajitas without all the toppings! My favorites include flour tortillas, shredded cheese, salsa or pico de gallo, and guacamole.
How to Make Crockpot Chicken Fajitas
Season chicken. Prepare the chicken by seasoning both sides with garlic powder, chili powder, salt, onion powder, cumin, black pepper, smoked paprika, and oregano.
Add fire-roasted tomatoes and green chiles. Pour the fire-roasted tomatoes and diced green chiles on top of the chicken and lightly toss to combine.
Slow cook. Cook the chicken on low for 5 hours or on high for 3 hours.
Add peppers and onion. Add the sliced bell peppers and onion to the crockpot and lightly toss together to combine. Cook for an additional 45 minutes. If you cook them any longer, the veggies may soften too much and become mushy.
Shred. Remove chicken from the crockpot with a slotted spoon and shred it in a bowl or on a cutting board using two forks. Add shredded chicken back into the crockpot, add lime juice, and toss together to combine. Taste and season with some salt and black pepper if needed.
Serve your crockpot chicken fajitas on warmed corn or flour tortillas and top with shredded cheese, salsa, guacamole, and sour cream for the ultimate weeknight dinner.
Recipe Tips
- If you prefer crisp bell peppers and onions, add them to the slow cooker and cook for only 30 minutes.
- For a leaner option, use boneless and skinless chicken breasts. For a juicier option, use boneless and skinless chicken thighs.
- Any color of bell peppers will work.
- To add some spice and heat, add in some jalapeños and/or poblano peppers.
Ways to Serve Crockpot Chicken Fajitas
The great thing about this recipe is its versatility. I love eating it with homemade flour tortillas or corn tortillas and toppings like shredded cheese, sour cream, and roasted tomato salsa.
However, if you don’t want tacos, you could make it into a fajita bowl with a base of cilantro lime rice or Mexican rice and some seasoned canned black beans.
It also makes an excellent topping for chicken tostadas or on a green salad!
Storing and Reheating
To store, place in an airtight container and refrigerate for up to 1 week.
To freeze, place in a freezer safe container or freezer bag and freeze for up to 3 months.
