I've run across some evidence in my research indicating that scalloped potatoes
may have originated in ancient Wales or other parts of the British Isles. However, I'd bet good money that the
addition of cubed ham and cheese to them makes this dish quite an American original! Outside the Midwest heartland of the U.S., this dish is thought to be primarily served at holiday
feasts such as Christmas or Thanksgiving. But it's a supper-time staple throughout the year in the Midwestern states.
"Scalloped" potatoes do not actually contain scallops - the term scalloped originally referred to seafood creamed and served hot in the shell.
You'll need an electric slow-cooker for this recipe!
Ingredients:
1 lb. (453.6 g) ham, cut into ½" (1.25 cm) cubes
8 to 10 medium potatoes, thinly sliced (see notes below)
2 white or yellow onions, peeled and thinly sliced
16 oz. (457.60 g) sharp Cheddar cheese, grated
1, 10-oz. (300 ml) can any brand condensed cream of celery soup
salt & ground, black pepper to taste
paprika

This is the size and thickness you want your ham cubes and potato slices!
Preparation:
Put half the ham, potatoes and onions in the slow-cooker. Sprinkle with salt
and pepper,then with grated cheese. Do the same thing with the other half of the ingredients. Spoon the soup straight
from the can evenly over the top (don't add any water to it!); sprinkle it all then with a good dusting of paprika.
Cover and cook on the "low" setting for 8 to 10 hours (or for only 4 hours on the "high" setting).
The ingredients may be cut in half, or increased by half, depending on how many mouths you have to feed and the
size of your slow-cooker! This recipe yields a good 6 to 8 helpings.

Mmm . . . hot and hearty, this dish is savory and satisfying!
Notes:
A waxy potato (red or white skinned) is recommended - these are the best to
use when solid slices are required, such as in this recipe.
