Spray the slow cooker generously with cooking spray.
In a large bowl, mix together all the meatloaf ingredients until well blended. Shape the meat mixture into a loaf and place the meatloaf on a sheet of foil OR place it directly in the slow cooker.
Add the potatoes around the meatloaf.
Cook on HIGH 3-4 hours or LOW 6-8.
30 minutes before cook time is completed, spread ketchup on top of meatloaf, cover & cook the remaining 30 minutes. You can also let the meatloaf cook the entire way through, remove it from the slow cooker, spread the ketchup on top and broil it in the oven for a few minutes.
