These no-fuss Crock Pot Chicken Fajitas are an easy weeknight dinner everyone will love!
The best part is that there’s just 10 minutes prep time involved. This is an unbelievably quick, simple and delicious recipe that’s always a hit… customize with your favorite fajita toppings!
If you prefer tender-crisp vegetables in your fajitas, add the peppers and onion during the last 30 to 45 minutes of cook time. This is how I prefer my veggies, but they can also be cooked at the same time with the chicken (they will just be very soft but are still delicious!).
The vegetables shown in the images were added during the last 30 minutes of cook time.
Once the fajita mixture has cooked, remove the chicken breasts and shred or slice, then return to the slow cooker and toss everything to combine. Fajita night has never been easier!
Fajita Topping Suggestions
- Sour cream
- Shredded cheese
- Diced tomatoes or salsa
- Sliced Avocado or guacamole
- Chopped fresh cilantro
