Can You Put Frozen Chicken in a Slow Cooker?
Using frozen chicken in a slow cooker is debated. Some slow cookers heat slowly, which can keep food in the danger zone too long. If you use frozen chicken, be sure your cooker brings food to a safe temperature and allow extra cooking time so the chicken reaches a safe internal temperature before serving.
How to Make Crockpot Chicken Fajitas
The method is straightforward and quick to prep:
- Make the seasoning: In a small bowl combine chili powder, ground cumin, paprika, dried oregano, salt, and black pepper.
- Layer the veggies: Coat the crockpot insert with olive oil and spread the thinly sliced onions and bell peppers across the bottom.
- Season the chicken: Rub the seasoning onto the chicken breasts so they’re evenly coated, then place them on top of the vegetables. Sprinkle minced garlic over the chicken.
- Cook: Cover and cook on high for about 2½ to 3 hours, until the chicken is cooked through and tender.
- Slice or shred: Remove the chicken, cut into thin strips or shred, then return it to the crockpot and stir to combine with the cooked vegetables.
- Serve: Warm the tortillas and fill with the chicken and peppers. Add lime wedges and your favorite toppings.
How Thin to Cut Chicken for Fajitas
- After the chicken is cooked, slice it into thin strips—about the thickness of a pencil or an asparagus spear—so it wraps neatly in tortillas and mixes well with the vegetables.
Recipe Tips
This recipe is flexible—adjust seasonings, ingredients, and toppings to suit your taste.
- Add heat: Add cayenne or minced jalapeño for more spice.
- Smoky flavor: Substitute smoked paprika or some chipotle powder for part of the chili powder.
- Extra veggies: Add zucchini, mushrooms, or additional peppers for more color and nutrition.
- Chicken choices: Boneless, skinless thighs are a great alternative and stay moist when slow-cooked.
Tasty Serving Suggestions
Serve the fajitas with warmed tortillas and fresh sides. Popular options include Mexican rice, elote or elote-style salads, and a simple avocado and tomato salad. Top fajitas with cilantro, cheese, sour cream, salsa, or slices of avocado for a complete meal.
How to Store and Reheat Crockpot Chicken Fajitas
- Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days.
