This is a great way to use leftover ham or even the bone from a bone-in ham. It's quick to toss together and you toss it into the crock pot and walk away. There is a bit to do at the end, but it's worth it. :)
3 1/2 cups diced potatoes
1/2 cup chopped celery
1/2 cup diced onion
3 1/4 cups ham (or however much you have, or just toss in the ham bone assuming there's still meat on it)
3 1/4 cups water or chicken broth
6 chicken bullion cubes (or 3 if you use broth--I used "better than bullion" vegetable base)
1/2 tsp salt
1 tsp pepper
5 Tbsp flour
5 Tbsp butter
2 cups milk (I use fat free, but it doesn't matter)
Spray crock pot with cooking spray and stir potatoes through pepper into the crockpot. Cook on low for 6-8 hours. If you use a ham bone, about 30 minutes before serving remove the bone, cut away ham from it, dice it, and stir ham back into crock pot. About 20 minutes before serving, melt butter in a saucepan, add flour and gradually add milk, stirring constantly over medium heat until thick. Stir mixture into crockpot. Let cook 15-20 minutes more.
Especially good served with some sharp cheddar cheese, chives, and crumbled bacon, but very tasty just as it is.
