Place the chicken breasts in the crockpot and sprinkle the taco seasoning on top. Toss to coat the chicken evenly in the seasoning.
Pour the salsa into the pot and toss again. Close the lid and set the temperature to low.
Cook on low for 4-6 hours depending on the size of the chicken breasts. You are looking for an internal temperature of 165F.
Once the chicken is cooked through, switch the temperature to warm. Remove the chicken from the crockpot and shred with two forks or a stand mixer.
Return the chicken to the crockpot with the salsa and mix it together.
Serve the chicken directly out of the crockpot on tortillas with all of your favorite taco toppings.
