8 oz. pkg. macaroni, cooked
12 oz. sharp Cheddar cheese, grated (save 1/2 c. to put on top)
1/2 stick butter
3 eggs, beaten
2 1/2 c. milk
scant tbsp. salt
dash of black pepper

Mix. Pour into large casserole. Sprinkle some of grated cheese on top.

Bake about 45 minutes. Check occasionally to see that it is not burning on top. Sometimes I place a piece of foil over it toward the end of the cooking period.
