Ingredients

Chicken and Vegetables

  • 2 lbs boneless, skinless chicken breasts or thighs
  • 1 red bell pepper, sliced into thick strips
  • 1 yellow bell pepper, sliced into thick strips
  • 1 green bell pepper, sliced into thick strips
  • 1 large yellow onion, sliced into thick strips
  • 2 tablespoons olive oil
  • Juice of 1 lime (added in the last 30 minutes only)

Seasonings

  • 1 packet (1 oz) fajita seasoning (or homemade blend below)
  • 1/2 cup salsa, any heat level

Homemade Fajita Seasoning (optional)

  • 2 teaspoons chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon dried oregano
  • Pinch of cayenne pepper (optional)

To Serve

  • Flour or corn tortillas, warmed
  • Shredded cheese
  • Sour cream
  • Guacamole
  • Fresh cilantro
  • Extra lime wedges


Instructions

  1. Prepare Vegetables: Add the thick-cut pepper strips and sliced onion to the bottom of the slow cooker. Drizzle with olive oil and spread them out evenly so the vegetables form a base for the chicken to sit on and baste throughout cooking.
  2. Season Chicken: Sprinkle the fajita seasoning generously on both sides of the chicken breasts or thighs, pressing the spices into the meat to infuse flavor.
  3. Layer Chicken and Salsa: Place the seasoned chicken directly on top of the peppers and onions. Pour the salsa over everything without stirring to keep the flavors intact.
  4. Slow Cook: Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours. Avoid lifting the lid during cooking. Check for doneness at the lower time range; the chicken is done when it reaches 165°F and shreds easily.
  5. Add Lime Juice: In the last 30 minutes of cooking, squeeze fresh lime juice over the chicken and replace the lid to finish cooking, adding bright citrus notes.
  6. Shred Chicken: Transfer the chicken to a cutting board and shred with two forks. Drain any excess watery liquid from the slow cooker, then return the shredded chicken and vegetables to the pot and toss together to combine.
  7. Optional Skillet Crisping: For crispy edges, spread a large spoonful of the shredded fajita mixture in a hot dry skillet over high heat for 2 to 3 minutes without stirring until the edges char slightly, adding a smoky, sizzling restaurant-style texture.
  8. Serve: Set the slow cooker to WARM and serve at the table. Warm tortillas and toppings allowing everyone to build their own fajita plate.

Notes

  • The slow cooker method creates tender, juicy chicken that shreds easily.
  • Do not lift the slow cooker lid during cooking to maintain heat and moisture.
  • Lime juice is added at the end to preserve its fresh citrus flavor.
  • The optional skillet step adds smoky crispness reminiscent of restaurant fajitas.
  • Customize toppings to your preference, including cheese, sour cream, guacamole, and fresh cilantro.
