Ingredients

24 oz salsa
1 red bell pepper, sliced
1 yellow bell pepper, sliced
1 green bell pepper, sliced
1 large yellow onion, thinly sliced
6 garlic cloves, minced
2 lb chicken breast, sliced into 1-inch strips
1 packet fajita seasoning (such as Old El Paso)
2 tbsp lime juice
1 teaspoon chili powder

Instructions

Step 1: Slice the chicken breasts into 1-inch strips and prepare the vegetables by slicing all bell peppers into thin strips, thinly slicing the yellow onion, and mincing the garlic cloves. Having everything ready before assembling ensures even cooking.
Step 2: Pour half of the salsa (about 12 oz) into the bottom of the crockpot. Layer half of the sliced peppers, half of the onion, and all the minced garlic over the salsa to create a flavorful base and prevent sticking.
Step 3: Arrange the chicken strips evenly over the vegetable layer. Sprinkle the fajita seasoning packet and chili powder over the chicken. Use your fingers to gently work the seasoning into the chicken for better flavor adherence.
Step 4: Layer the remaining salsa over the chicken, then top with the remaining peppers and onions. Squeeze the lime juice evenly over everything. Stir gently once to distribute the seasonings throughout.
Step 5: Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken reaches an internal temperature of 165°F. This slow cooking makes the chicken tender and flavorful while softening the vegetables.
Step 6: Using two forks, shred the cooked chicken directly in the crockpot and mix it well with the salsa and vegetables. Keep the crockpot on the warm setting until ready to serve to maintain moisture and temperature.

Tips & Variations

For extra flavor, add a splash of chicken broth to the salsa layers before cooking to increase moisture.
Use homemade fajita seasoning to control salt and spice levels.
Serve with warm tortillas, avocado slices, sour cream, and shredded cheese for a complete meal.
For a low-carb version, serve with cauliflower rice instead of tortillas.

Storage

Store leftover fajitas in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stovetop to prevent drying out. This dish also freezes well; thaw overnight in the fridge before reheating.
