Spray a 4-quart slow cooker with cooking spray and add macaroni, evaporated milk, whole milk, butter, salt, pepper, and eggs.
Stir in all but 1/2 cup of the cheese.
Sprinkle the remaining cheese and paprika on top.
Cover and cook on LOW for 3 hours 15 minutes.
Notes
This recipe can also be cooked in a 9 X 13-inch pan coated with butter and placed in a 350 degree oven for 50 minutes.Many people have had success placing uncooked macaroni in the slow cooker instead of cooked.Do NOT use extra-sharp cheddar cheese. It tends to curdle in a crock pot.
