Can You Put Frozen Chicken in a Slow Cooker?
Using frozen chicken in a slow cooker is debated. If your slow cooker heats slowly, frozen chicken can remain in the temperature “danger zone” too long. For food safety, it’s best to thaw chicken before cooking. If you must use frozen chicken, increase the cook time and ensure the internal temperature reaches 165°F (74°C) before serving.
How to Make Crockpot Chicken Fajitas
The method is straightforward and beginner-friendly. Prep takes about 15 minutes and cook time around 2½–3 hours on high.
- Mix the seasoning: In a small bowl combine chili powder, cumin, paprika, oregano, salt and pepper.
- Prep the crockpot: Coat the insert with olive oil and spread the sliced onions and bell peppers across the bottom.
- Season the chicken: Rub the chicken breasts evenly with the fajita seasoning and place them on top of the vegetables. Sprinkle minced garlic over the chicken.
- Cook: Cover and cook on high for 2½ to 3 hours, until the chicken is cooked through and tender.
- Slice or shred: Remove the chicken, slice into thin strips (about the thickness of a pencil) or shred, then return it to the crockpot and stir to combine with the vegetables and juices.
- Serve: Warm tortillas, fill with the chicken and vegetables, and top with lime wedges and desired toppings.
How Thin to Cut Chicken for Fajitas
Slice the cooked chicken into thin strips—about the thickness of a pencil or an asparagus spear. Thin slices fold easily into tortillas and create the classic fajita texture.
Recipe Tips
- Add heat: Increase spice with cayenne pepper or minced jalapeño.
- Smoky flavor: Swap some chili powder for chipotle powder or use smoked paprika.
- Extra vegetables: Zucchini, mushrooms, or sliced tomatoes make good additions.
- Chicken choice: Boneless, skinless thighs work well if you prefer darker meat.
