This recipe for slow cooker mac and cheese is a blend of tender pasta with two types of cheese and plenty of seasonings, all cooked together to creamy and cheesy perfection. It’s the easiest crock pot macaroni and cheese ever!
This macaroni and cheese is total perfection, my kids absolutely adore it and ask for it every week. Serve it with a roasted chicken and sauteed asparagus for a complete meal that’s sure to get rave reviews.
I’ve found that homemade mac and cheese can be a little tricky to get right. Sometimes I have issues with the sauce separating or being grainy from the flour, and I find that baked versions of mac and cheese can dry out easily. This slow cooker mac and cheese is practically fool proof; it comes out ultra creamy every time thanks to a secret ingredient.
HOW DO YOU MAKE SLOW COOKER MAC AND CHEESE?
This crock pot mac and cheese is very simple to make. First step is to boil you noodles. Slow cooker mac and cheese can sometimes come out with mushy, overcooked pasta if it cooks for too long. To avoid that, I use a heartier noodle like cavatappi, and I undercook it by 2 minutes before I put it into the slow cooker. The noodles are coated with butter, then mixed with cheddar cheese, evaporated milk, half and half, and seasonings. And now for the secret ingredient reveal: American cheese! Not the kind that comes in the little slices wrapped in plastic; go to your deli and buy a block of American cheese to cut into cubes for this recipe. This cheese melts beautifully and makes the end result ultra creamy. In about 2 hours you’ll have mac and cheese perfection!
Tips for perfect crock pot mac and cheese
- The cook time for this mac and cheese varies a bit depending on your slow cooker. I find that some of the older slow cookers tend to run on the hot side and have less heat settings. If you’ve got an older crock pot, cook this mac and cheese for about 1 1/2 hours to avoid mushy noodles.
- If you’ve got a more modern crock pot with multiple heat settings, cook on the lowest setting for 2 hours. Either way you’ll want to stir the mac a few times during the cooking process. If it looks soupy at the end of the cook time, just keep stirring and it will come together into a smooth sauce.
- I recommend grating your own cheddar cheese for this recipe. The bagged pre-shredded cheese sold at the grocery store is often coated in anti caking agents and preservatives and does not melt as smoothly as freshly grated cheese.
CAN YOU FREEZE SLOW COOKER MAC AND CHEESE?
You can freeze mac and cheese for up to 3 months. Make sure to avoid freezer burn by storing your mac and cheese in an airtight container or resealable freezer bag. Thaw the macaroni and cheese in the fridge before you reheat it.
The American cheese, combined with cheddar cheese, butter, half and half and evaporated milk, make the sauce perfectly smooth. This is a basic mac and cheese in terms of the seasoning profile, but you can amp it up with the addition of your favorite herbs and spices, or even add some cubed ham at the end of the cook time for an extra special treat!

Hello! This sounds amazing! Trying to use what I have at home already. I have the block American cheese. Would it be ok if I used shredded Fiesta blend instead of the cheddar cheese? Also, I have heavy whipping cream .. could I use that instead of half and half so I save a trip to the store?
Sara says
Yes both of those substitutions will work!
Bre Olsen says
Would sliced American cheese from the deli work as well? I forgot to tell to them leave in in a block so I could cube it for the recipe. Could you also use Velveeta for the american cheese?
Sara says
Yes sliced american cheese or velveeta are both fine!
Miranda says
My family & friends ask me to make this for get-togethers/dinner regularly! It’s so delicious and creamy.
Deb says
I left it on warm and everyone could just eat when they wanted. It was very tasty!
Cali says
Hi! Is it possible to use whole milk in place of the evaporated milk and half and half? Thanks!
Sara says
It could work but whole milk doesn’t thicken in the same way so you may want to use less.
Tigger says
As a UK resident, what is American cheese? And why do you refer to the pasta as noodles?
Sara says
American cheese is a processed cheddar flavored cheese that melts smoothly and does not separate. In America macaroni is typically referred to as “elbow noodles”.
Massachusetts Cook says
I made the recipe exactly as stated for a Super Bowl potluck. It was delicious and didn’t last long. Then I made the recipe again for a work potluck. This time I doubled the batch and used Cabot’s mild cheddar cheese w/bacon and plain mild cheddar (grated cheese at home). The other ingredients were the same. People went crazy over this! This is now one of my all-time favorite recipes. In the summer I will stick to the plain cheddar cheese and will add lobster meat.
Kristen says
Salted or unsalted butter?
Sara says
I use salted but either will work.
