This is from Singer (and cook) Trisha Yearwood's Second Cookbook -- home cooking with tricia yearwood
8 ounces elbow macaroni, cooked
1 12-ounce can evaporated milk
1 1/2 cups whole milk
2 large eggs, beaten
1/4 cup (1/2 stick) butter, melted
1 teaspoon salt
Dash of pepper
2 10-ounce bricks sharp Cheddar cheese, grated (about 5 cups)
Dash of paprika
In a large 4-quart crockpot sprayed with cooking spray, mix the macaroni, milks, eggs, butter, salt, pepper, and all but 1/2 cup of the grated cheese. Sprinkle the reserved cheese over the top of the mixture and then sprinkle with paprika. Cook on low heat for 3 hours and 15 minute Turn off the crockpot, stir the mixture, and serve hot.
If you don't have a crockpot, grease a 9 x 13 x 2-inch pan with butter, add the mixture, and bake at 350 degrees for 50 minutes.
