Easy Slow Cooked Three Cheese Mac and Cheese Recipe
Do different slow cooker really cook macaroni and cheese differently? The short answer is, yes, they do. Cooking times can vary depending on the shape, size and age of the slow cooker you’re using. Some slow cookers only have a heat source on the bottom while most conventional slow cookers cook on all sides. I’ve tested this recipe in both types and note that it required very little, to no adjustment, in the cooking time.

Recipe Variations, Tips and Substitutions
- Cheese – When making this dish, you can certainly shake-up the flavor of the cheeses used. If you’d like to add a bit of heat, use pepper jack in place of one of the cheddar cheese used in the combo. You can also create your own flavor combination using your favorite types of shredded cheese like mozzarella, colby jack cheese, gruyere, swiss or monterey jack cheese.
- Pasta – You can use twisted macaroni or cavatappi pasta in this recipe.
- Grate Your Own Cheese – In this recipe I use combination of three cheddar cheeses. You can use a package of shredded cheddar cheese blend for a shortcut.
- Check for Doneness – In a conventional slow cooker, I recommend you cook on low for 2 hours, and check the center for doneness. It may be completely cooked in that time. After testing a tiny bit from the center sprinkle the remaining cheese on top and keep warm until it melts.
- Adjust the Cooking Time as Needed – If the macaroni and cheese isn’t completely cooked at 2 hours, you may need to increase the time by 30-60 minutes, based on how your slow cooker cooks.
- Sour Cream – When whisking together the ingredients for the sauce make sure it’s well blended and use a quality full fat sour cream for the best results. Don’t be tempted to keep stirring or the sauce will break.
Storage and Leftovers
- Leftovers – Store leftover triple cheddar macaroni and cheese in an airtight container chilled in the refrigerator for up to 4 days.

- Freezer – You can freeze leftovers for up to 2 months. Thaw in the fridge and reheat just before serving.

I made this today for Thanksgiving and it came out beautifully. I about doubled the recipe in my slow cooker, but didn’t seem to matter. Everyone talked about how good it tasted. Definite two thumbs up.
Yes, doubling in a 6 quart slow cooker should be fine. An oval would be ideal, so be mindful of your slow cooker, and it’s shape, and adjust the time as needed. Once cooked, for the best results, serve it then. If it’s necessary, once cooked, keep it on the lowest setting to prevent changing the texture of the pasta.
after reading recipe and comments…i think i am gonna try your mac n cheese…..i have a thanksgiving lunch at work on tues…about 20 people i suppose….i have a 6 qrt crock pot and you mentioned that doubling recipe is ok….you did mean doubling in a 6qrt right….it will all fit right ? 🙂 any suggestions on cooking/keeping warm?….i go to work at 5 am and we’ll b eating lunch about 11?
When slow cooking, generally a dish that cooks on low for 2 hours, would cook in 1 hour on high. This could vary based on how your slow cooker performs. So, I would recommend checking it at 1 hour. If the center is creamy but set when gently shaken, it’s done. If not, continue to cook and check it every 15 minutes to avoid over cooking.
For some reason, my slow cooker does nothing on low. How long would I cook this on high?
Looks fantastic!
It should be creamy, but set when gently shaken.
It’s in the crock pot and looks yummy! What does it look like in the middle when you check if it’s ready? Mines a little watery still
Wonderful, so happy to hear you enjoyed this dish. Rotini pasta does make a yummy mac-n-cheese, good call. ☺
I made this tonight to go with dinner and omg is it ever yummy!! I used the oven method as nobody wanted to wait for it to cook in the crockpot. Thank you so much for this recipe…no more boxed mac n cheese here! This is just yummy gooey cheesy goodness, and so easy! I didn’t have elbow macaroni so I used rotini…it really holds the cheese sauce in!
Great idea, so happy you enjoyed.
I just made this tonight for dinner! It was very yummy! I added French’s french fried onions for a bit of a crunch!
I use Campbell’s Cheddar Cheese soup. It holds up quite well to the slow cooking process, and blends with the milk and cheese beautifully. Enjoy!
Hi melissa, what brand of cheese soup do you use?
Sure!
Can I freeze the left overs Melissa?
Michelle, thanks so much for leaving a comment about how this dish is without eggs. I’m delighted you enjoyed it! ~ Melissa
I made this tonight & it was amazing. I left the eggs out & used medium shell noodles because I didn’t have any elbows. Wonderfully moist & cheesy!
Sure, I haven’t had a problem with it drying out. However, I wouldn’t recommend leaving it for an extended length of time.
Bowing can you keep on warm before serving , so it doesn’t dry out?
