You will need a 2 quart casserole with a lid.
Preheat your oven to 375 degrees Fahrenheit.
5-6 medium sized potatoes
1 to 1-1/2 cups cubed ham
1/4 cups flour
2 Tablespoons butter
1 cup milk
Peel and slice the potatoes.
Arrange the potato slices and ham cubes in the casserole dish so that they are distributed evenly.
Sprinkle the flour over the top of the potatoes and ham.
Cut the butter into cubes and put over the flour.
Pour the milk over all.
Sprinkle it all with salt and pepper.
Cover the casserole and bake in the preheated over for about an hour.
After 50 minutes, stir the ham and potatoes and check to see if the potatoes are done.
If it seems dry add a bit more milk.
Cover and put back into oven if needed.
Check in another 10-15 minutes.
When potatoes can be pierced with a knife or fork easily, the dish is done.
