Place the chicken breasts in the bottom of the Crock-Pot. Season with garlic powder, onion powder, thyme, salt, and pepper.
Add the chopped onion, cream of chicken soup, and chicken broth over the chicken. Stir gently to combine.
Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
Remove the chicken from the Crock-Pot and shred it using two forks. Return the shredded chicken to the pot.
Open the biscuit dough and cut each biscuit into quarters. Drop the biscuit pieces into the Crock-Pot, stirring gently to combine.
Cover and cook on high for an additional 30-40 minutes, until the biscuits are cooked through and fluffy.
Serve hot and enjoy!
