Combine chicken, broth, butter and dressing mix in crock pot and cook on high for 3 1/2 to 4 hours. Chicken should shred into small pieces.
Add remaining ingredients and cook on high for another half an hour. Add milk or heavy cream to thin the sauce if it’s too thick. Serve over noodles or rice.
*Today we had all the ingredients to make this dish EXCEPT for the dry Good Seasons Italian Dressing Mix. We didn't want to go to the store, so we made our own mix, it turned out great! Here is what we used:
-3 tsp. Montreal Chicken seasoning (if you don't have this, you can mix together a little salt, garlic powder, onion powder, and black pepper together.. and maybe even a dash red pepper flakes)
