Cheesy Potato Soup

This is one of my favorite soups. Starch and fat... can't get better than that on a cold day. The ultimate comfort food!
4 baking potatoes (1 1/2 lb) - Yukon Gold are good
2 T butter 2 C potato water
1 C chopped carrots 1 1/2 C whole milk
1 medium onion, chopped 1 C shredded cheese (cheddar)
1 t. bouillon salt and pepper to taste

Cut and boil potatoes and carrots in large pot until just soft. Drain all but about 2 C of water. Mash potatoes coursely in pot.

Saute butter and onion in pan. Add onion/butter to potatoes. Add bouillon and milk and heat on low. Add cheese until melted. Salt and pepper to taste.

Can easily make a double batch.
