8 cups leftover smashed (or roughly mashed) potatoes
3 cups cooked ham, chopped small
2-4 cups milk
kosher salt, to taste
freshly ground black pepper, to taste
1. Combine the potatoes and ham in the crock-pot. Pour enough milk into the crock-pot to almost cover them. Stir or smash with a heavy spoon to combine.
2. Cover with lid and cook on LOW for 4 hours or HIGH for 2 hours. Stir and lightly smash any large chunks of potato. Season generously with salt and pepper, taste and adjust as needed.
3. Cover again and cook for 1-3 more hours on LOW. Add more milk as desired to thin the soup to your desired thickness. Serve with crusty bread for dipping.
