Season the chicken breasts with salt, pepper, garlic powder, onion powder, and smoked paprika. Place the seasoned chicken breasts in the crock pot.
In a medium bowl, whisk together the honey, Dijon mustard, whole grain mustard, apple cider vinegar, olive oil, and minced garlic to create the honey mustard sauce.
Pour the honey mustard sauce over the chicken breasts in the crock pot, making sure the chicken is evenly coated.
Cover the crock pot and cook on low for 4-6 hours or on high for 2-3 hours, until the chicken is cooked through and reaches an internal temperature of 165°F.
Once done, remove the chicken breasts from the crock pot and place them on a cutting board. Use two forks to shred the chicken into bite-sized pieces.
Return the shredded chicken to the crock pot and stir to coat it evenly with the honey mustard sauce.
Serve immediately while warm and enjoy!
Notes
I like the combination of Dijon mustard and whole grain mustard in the sauce that adds a nice texture and depth of flavor, but you can use all Dijon mustard if you don't have whole grain mustard on hand. Refrigerate any leftovers in an airtight container for up to 5 days.
