Prep the Ingredients: Dice the onions, carrots, and celery. If using homemade biscuits, prepare the dough and refrigerate until needed.
Slow Cook the Chicken: Add the chicken, chicken broth, butter, garlic powder, onion powder, thyme, rosemary, sage, Worcestershire sauce, diced onions, carrots, and celery to the crock pot. Cover and cook on LOW for 6-8 hours or HIGH for 3-4 hours, until the chicken is fully cooked.
Shred the Chicken: Remove the cooked chicken from the slow cooker, shred with two forks, and return to the crock pot. Stir in the frozen peas.
Thicken the Sauce: In a small bowl, whisk together the flour and heavy cream. Pour into the slow cooker, stir, and let cook on HIGH for 30 minutes until thickened.
Add the Biscuits: You have two options:
Bake Separately: If you like crispier biscuits, bake them in the oven according to the package or recipe instructions.
Bake on Top: Place raw biscuits directly on top of the filling in the crock pot, cover, and cook on HIGH for 30-45 minutes until golden brown.
Serve & Enjoy: Scoop out generous portions of chicken pot pie with biscuits on top and serve warm.
