How to Make Crockpot Chicken Fajitas the Whole Family Will Love
Wash and cut the vegetables into strips. Mince the garlic.
Place the chicken in the bottom of the slow cooker.
In a bowl, mix the peppers, onions, and garlic with olive oil. Pour this mixture over the chicken.
Sprinkle the fajita seasoning and add the Rotel tomatoes.
Cook on high for 3-4 hours or on low for 6-8 hours. Once done, remove the chicken and cut it into strips.
Put it back in the slow cooker and mix everything together.
Serve in flour tortillas with chopped cilantro and your favorite toppings.
Hint: Use a mix of colorful bell peppers—not just for the flavor but because they make the fajitas look extra inviting (especially for picky eaters who love a little color on their plate!).
Substitutions & Variations
- You can use boneless, skinless chicken thighs instead of breasts for a richer flavor and even more tenderness.
- If you don’t have Rotel, use regular diced tomatoes and add a small can of green chiles or a dash of hot sauce.
- A homemade blend of chili powder, cumin, garlic powder, paprika, and salt works great if you're out of fajita seasoning.
- Flour tortillas are classic, but corn tortillas or even lettuce wraps work if you want something lighter.
- Toss in some black beans or frozen corn halfway through cooking for a heartier meal.
- For toppings, sour cream, shredded cheese, guacamole, salsa, chopped lettuce, or even pickled onions all work great.
💭Crucial Success Tips
- Slice veggies evenly so they cook at the same rate and don’t turn to mush.
- Use olive oil—it helps the veggies stay tender without getting soggy.
- Warm your tortillas before serving—they’re just better that way!
- Don’t overcook—even in a slow cooker, chicken breasts can get a little dry if left too long on high.
