Being born and raised in the South, we know what makes a great macaroni and cheese recipe. This version is a great recipe to serve to a crowd since the cheese sauce can be made in the crockpot up to a couple of hours in advance. All the cooking needed is boiling the noodles and tossing them into the slow cooker an hour before serving.

We love to serve it with our Spicy Pulled Pork and Bratwurst Burnt Ends for a meal that everyone will be asking for seconds of.

Pro Tip: In order to make sure your noodles don’t overcook in the slow cooker and the cheese sauce stays moist and not dry, boil them separately on the stovetop then add them to the crockpot. This makes the best mac and cheese.

Storage

Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or on the stovetop with a splash of milk until warmed though.

We don’t recommend freezing the leftover slow cooker mac and cheese since it will change the texture once it thaws.
