Corned Beef Hash Casserole

1 (1 pound 10 ounce) package frozen shredded
    hash browns, partially thawed
2 cups cooked corned beef, or canned
1 medium onion, finely chopped
2 teaspoons celery seed
Salt and pepper, to taste
1 1/2 cups shredded American or combination American/Cheddar cheese
1 can cream of celery soup
1/2 cup evaporated milk

Lightly butter a 3 1/2- or 4-quart crock pot. Sprinkle about one fourth of the potatoes in, followed by one third of the onion and one third of the corned beef. Sprinkle with celery seed, salt and pepper. Repeat two more times, ending with the remaining potato, 1/2 cup cheese, and another sprinkling of salt, pepper and celery seed.

Mix together the cream of celery soup and evaporated milk; pour over the potato mixture. Cover and cook on LOW for 7 to 9 hours.
