Ingredients

  • 2 pounds boneless/skinless chicken breasts
  • 1 can 14 ounces fire-roasted diced tomatoes
  • 1 tablespoon extra-virgin olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried oregano
  • 1/2 teaspoon black pepper
  • 1.5 teaspoon salt divided
  • Optional for extra spice: 2-3 Chipotle Peppers in Adobe from one can. Finely chop one pepper for very mild spice, two peppers for more of a kick, and three peppers for extra spice.)

Instructions

  • Lightly grease a 6-quart crockpot with cooking spray.
  • Season both sides of the chicken with 1 teaspoon salt and 1 teaspoon pepper.
  • Heat olive oil in large skillet and add chicken. Cook each side 2-3 minutes or until lightly browned (they do not need to be cooked all the way through.) Transfer to crockpot.
  • Sprinkle the chicken with the chili powder, garlic powder, onion powder, and remaining 1/2 teaspoon of salt.
  • Pour in the can of fire roasted diced tomatoes (including the juices.) If using the chipotle peppers, place them on top.
  • Cover and cook on low for 4-5 hours or on high for 1-2.5 hours (or until the chicken is cooked all the way through and no longer pink on the inside.)
  • Transfer the chicken to a cutting board and let it rest for 5 minutes. Shred and return to the crockpot, stirring in the juices so the flavors fully absorb. Cook for an additional 15 minutes.
  • Serve with preferred sides and enjoy!

This is a great meal for leftovers. They can be repurposed into a completely different dish the next day!

Add a splash of water or broth to refresh, if needed.
You can freeze leftovers in an airtight container in the freezer for up to 3 months, or you can even prep this whole recipe in advance and store in the freezer as a make-ahead meal.
