This slow cooker version of classic mac and cheese combines cooked pasta with a creamy, cheesy sauce made from sharp cheddar, evaporated milk, butter, and seasonings. The dish develops a rich, velvety texture as the cheese melts uniformly, resulting in an irresistibly gooey and comforting meal with minimal effort.
For extra flavor, stir in cooked bacon bits or sautéed vegetables before serving. Leftovers reheat well in the microwave or oven.
