Crockpot mac and cheese is rich, creamy and almost hands off. The dry macaroni cooks right in a mix of milk, evaporated milk and cheese, so there is no draining and no flour sauce to babysit.
A full slow cooker feeds ten for about $9.52, roughly $0.95 a serving, which makes it one of the cheapest crowd pleasers you can bring to a holiday table or potluck.
Holiday mac and cheese without the boiling pot
- Evaporated milk keeps the sauce smooth and stops it from splitting.
- Uncooked pasta goes straight into the slow cooker.
- It holds on WARM for an hour, which makes it perfect for holidays and potlucks.
Tips for the best crockpot mac and cheese
- Cook on LOW only. HIGH heat makes the edges scorch before the pasta is tender.
- Slow cookers vary a lot, so start checking the pasta at 1 hour 45 minutes.
- If the sauce looks thick on WARM, stir in a splash of milk.
- Use an instant read thermometer and check the USDA safe minimum internal temperature chart to know exactly when meat is done.
Ingredients for crockpot mac and cheese and easy swaps
- Elbow macaroni: Regular dry elbows work best. Do not use pre-cooked pasta or it will turn mushy.
- Evaporated milk: It is the secret to a smooth, stable sauce that does not split or turn grainy.
- Sharp cheddar: Shred it yourself from a block if you can. Bagged cheese melts a little less smoothly.
- Dry mustard: You will not taste mustard, but it makes the cheese flavor stronger.

Frequently asked questions about crockpot mac and cheese
Do you have to boil the noodles first?
No. The dry macaroni cooks in the milk in the slow cooker. That is what makes it so easy.
Can I make crockpot mac and cheese on HIGH?
We do not recommend it. HIGH heat can scorch the cheese at the edges before the pasta is tender.
How far ahead can I make it?
It is best served within an hour of cooking. It holds on WARM for about 1 hour with an extra splash of milk.
