How to Make Crockpot Chicken Fajitas
- Prepare the Ingredients: Start by slicing the bell peppers and onion into strips, and mince the garlic cloves. Lay your chicken breasts at the bottom of the crockpot.
- Add Seasonings: Sprinkle the fajita seasoning mix and black pepper over the chicken, ensuring an even coating.
- Combine the Veggies: Layer the sliced onions and bell peppers over the seasoned chicken.
- Pour in the Tomatoes: Open the can of mild diced tomatoes with green chiles and pour it all over the top.
- Incorporate the Lime Juice: Squeeze the fresh lime juice directly into the crockpot for that zingy brightness.
- Slow Cook: Cover and cook on low for 6–8 hours or on high for 3–4 hours. The chicken should be tender and easily shredded when done.
- Shred the Chicken: Once cooked, remove the chicken breasts from the crockpot and shred them with two forks. Mix them back into the delicious juices and veggies.
- Serve: Warm the tortillas and fill them with the chicken fajita mixture. Top with fresh cilantro and sour cream if desired, and enjoy!
Storing & Reheating
To store any leftovers, let your Crockpot Chicken Fajitas cool to room temperature. Transfer them to an airtight container and refrigerate for up to 3 days. You can also freeze the fajitas for up to 3 months if stored in a freezer-safe container. When reheating, warm the mixture in a skillet over medium heat for about 5–7 minutes or until heated through. If the texture seems a bit dry upon reheating, add a splash of chicken broth to refresh it.
