Scalloped potatoes are a necessary accompaniment to ham for me. We love them!
I combined a few recipes I found on allrecipes.com to create one that worked best for us. We don't like a lot of cheese or too heavy of a sauce, so this blend of broth with a bit of milk works great. Here is my favorite scalloped potato preparation.
6 large potatoes
1 large onion
salt and pepper
4 tablespoons butter
1/4 cup flour
2 cups chicken (or vegetable) broth
1/4 cup shredded cheese
1/4 cup milk
Peel potatoes and then slice them with mandolin slicer into 9x13 baking dish. Do the same with the onion, mix together, and add salt and pepper (as you can see, s&p has not been added as of this picture!).
Melt butter in saucepan and stir in flour. Slowly add broth and milk, stirring constantly. Add cheese and stir until slightly melted. Pour over potatoes and bake at 350 for 1 hour.
