Slow Cooker Macaroni and Cheese (or Crock Pot Mac and Cheese) is a creamy, cheesy and easy macaroni and cheese recipe.
CROCK POT MACARONI AND CHEESE
This recipe is my go-to Mac and cheese recipe when I don't have oven space and I want a recipe I know that everyone will love. This fits the bill every single time!
HOLIDAY MUST-HAVE SIDE DISH
The slow cooker is your friend during the holidays. This isn't really a "fix-it and forget-it" type slow cooker recipe but it does free up precious oven space and keeps you from having to stand guard the whole time and making sure things don't burn or over-cook. Also, if you need tips on FRYING A TURKEY, I got you covered!
WHAT MAKES IT THE BEST MACARONI AND CHEESE?
Using freshly grated cheese. Don't use the bag stuff. I don't mind using it for my NO-BOIL MACARONI AND CHEESE - but for this, you really need to freshly grate the cheese. It really makes all the difference here! Also the American cheese in this recipe helps to keep it so creamy. Don't skip it!
INGREDIENTS NEEDED: (FULL RECIPE AT THE BOTTOM OF THE POST)
elbow macaroni
salted butter
evaporated milk
half & half
shredded cheddar cheese
white American cheese
salt
pepper
Cook's Notes: Just go to your grocery store's deli counter and ask for ¾ pound of white American cheese. Tell them you don't want it sliced, just a big block.
HOW TO MAKE SLOW COOKER MACARONI AND CHEESE:
Cook the pasta according to the package directions until al dente (should still have a little 'bite' to it.)
Spray a 4-quart slow cooker with nonstick cooking spray.
Place the cooked macaroni into the slow cooker. Add the butter and stir until coated.
Pour in evaporated milk & half & half. 
Then add 2 cups shredded cheddar cheese, cubed American cheese salt & pepper. Stir to blend.
Cover and cook on low for 1 ½ to 2 hours (gently stir occasionally as it cooks.)
During the last 15 minutes of cooking, top with remaining cup of shredded cheddar cheese. Cover and allow cheese to melt.
Once done, turn the slow cooker to the warm setting until ready to serve. Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.

Great recipe! Everyone loves it and it is now my go to for parties and larger gatherings. I usually cannot find the block cheese of White American at the deli counter so I use either a block of Monterrey Jack or Colby Jack as a substitute.
Woo hoo! So glad to hear that and thanks so much for coming back to comment and leave a review!
I'm still in search for the perfect mac and cheese for my family. Who knew there could be so many variations. This one sounds perfect and looks yummy! I'm wondering if this one can be made on the stove top or in the oven, instead of the crock pot?
I did a slight variation of this recipe. I made it in a double batch, grated the American cheese instead of cubing it, and used garlic salt instead of salt. To cut down on the mess, I mixed everything together in a huge bowl before transferring it to the crock pot. I was in a hurry and didn't have time for the butter to soften, so I cubed half a stick (for the double batch) and microwaved it for 30 seconds so it was about half melted, half solid and incorporated it into the noodles that way. It's cooking now, and so far, so good! I'll update with the cook time if it needs more time!
can you use a crock pot liner for this recipe? Thinking about making this for Christmas dinner.
I used a crock pot liner in mine, but I mixed everything beforehand so I wouldn't tear the liner trying to mix it well and then dumped it into my lined crock pot.

This was THE BEST Mac and cheese recipe I have ever made!!!!! Thank you, Thank you, Thank you! This will be our go to forever!
I’ve made this several times, and it’s a huge hit. My nephew even asked me to make it for him for Christmas. I’m doing prep for Thanksgiving today, and I’m wondering how it would freeze since I don’t need the full recipe and don’t want to waste the extra ingredients. Has anyone tried?
easy to follow and tastes great even though i put corn and chicken into the recipe also.
love this recipe - and I don't typically like mac and cheese! a couple of hints: for those that don't love cheddar, colby is a great substitution - it melts a little better and isn't as strong in flavor. Second - when you go to the deli to get .75 lb white american, have them slice it in 1/2" thick slices - makes the cubing SOOO much easier.
my question is have you ever made this ahead and frozen it in a casserole dish to be heated later in the oven? thinking about sending it with my husband on a guys fishing trip but want to make it as easy for them as possible. thoughts?
I just posted a question about freezing it before I saw yours, now I feel a little silly. Did you try freezing?
THIS is some of the best Mac & cheese since my granny!!
This was a HUGE hit at my house. We made a Mac and Cheese bar With this recipe as the starting point and then made other things people could add. We had lobster, buffalo chicken, Bacon, chives, and broccoli just to name a few!!!
This has become a weekly dinner in my house. Thank you!!!
Julie - that is the best idea ever!! Why didn't you invite me?!?! Ha! I love it! You were so sweet to take the time to come back and leave such great feedback!
I would like to try this for our upcoming Super Bowl party, if I double the recipe does it need a longer cook time... we also love love bacon, and would like to add some pre cooked bacon to this, is it beat to add into the mixture at the beginning or end of cook time..thank you ..
Hi Wendy, it shouldn't need a longer cook time. Just keep an eye on it. You may want to cook it in two separate crock pots so you have more even cooking.
Hi! I'm planning on making this recipe this weekend. I'd prefer not to cook the noodles...could I just cook it longer in the crockpot? Or do I really need to cook the noodles beforehand?
You really need to cook them beforehand for this particular recipe. 🙂
This recipe is the best. My family loves it.
This definitely is a new favorite recipe of mine. Even my picky toddler loved it!
I only have 1% milk will it be ok to use in this recipe
Hi Brandie, How many people does this feed? I have a work party I'd like to make this for. Can the ingredients just doubled? If so, how big of a crock pot is needed? I think My crock pot holds six quarts. Thank you for your help..
Hi Harriet! If this is just going to be a side dish - it should serve about 8-10 people. You could double it and it should still fit into a 6-quart or larger.
Thanks for sharing this recipe, made it for a friendsgiving get together and it was a hit! Directions were spot on and I only made one addition to add texture to the mac & cheese; Picked up some Parmesan cheese and used a skillet to brown a few cheese pancakes (very thin browned cheese that is crispy) which I tossed in under the last cheddar addition for additional texture. It was a wonderful result. I will definitely use this again, appreciate the posting.
Hi John! Thanks so much for coming back to review! That is a really neat idea. I would have never thought of that. Thanks so much for sharing!
This is the best Mac and Cheese!! Kids and adults love it!!
Absolutely love hearing that! Thanks so much Lisa!
This worked out really well for my family. I didn’t use white American cheese but I replaced it with Colby/ Monterey Jack. I only did that because those were the cheeses my grandma used and I knew all my cousins and such would like that. Next time I think I’ll try crumbling some corn flakes on top. I also want to try it with white American for my kids.
Love it!! So happy you added a bit of your Grandma's extra special touch to it. Makes it so much more special!! Thank you Anna!!
Brandie,
This is the best mac and cheese ever! Just the way I like it, dense and cheddar cheesy. Although, I have to say I think the magic ingredient is the white American cheese. I made this for a party as a side to bbq ribs (perfect) and one of my meat eaters said "I don't really eat mac and cheese but this is great. Will you give my wife this recipe?" And did I mention how easy it is to make without heating up the kitchen?
Oh my gosh - thank you Gale! And you are a woman after my own heart by serving them with ribs - ha!! I love it! Thank you for taking the time to come back and let me know how it turned out for you!!
I don’t have half & half, can I use heavy cream instead and how much ?
Hi Elaine, I would start with the recipe measurements then add more if necessary to make it creamier. 🙂
I want to make this for my son's 6th birthday party. So far I've got 14 adults and 15 kids that have rsvp'd yes. How many does this recipe serve and would I just double everything to make more?
Thanks
Robyn
Quick, easy and a BIG HIT for our family get-together. I made this for a family luncheon and took a lot of time trying to find it again for my daughters first birthday party. IMHO, the best slow cooker, mac and cheese recipe on-line. It's printed as my go-to from here on out!
Woo hoo!! So awesome to hear this. Thank you Sarah!!
Amazing recipe! I’ve made this 3 times for family get-togethers, and this is THE HUGE HIT. My family is so excited to see me walk in with a crockpot of this Mac & cheese recipe. I actually had my deli go ahead and put it into slices for me, which made it easier on me to just lay the slices down in the crockpot instead of having to go home and cube it!
Hi Courtney! You made my day - thank you!! Thank you for taking the time to come back and leave such a wonderful review!
Can I make the cheese sauce in the crockpot and pour over the cooked pasta later? Thanks.
I use 2/3 Mexican cheese blend and 1/3 shredded pepper jack. White American for the block cheese. And add 2 eggs to the mixture. It keeps the consistency great and comes out delicious! It’s a hit at any gathering I make it for.
Excellant and so easy!
I just made for a family dinner. I didn't have half and half so I added two cans of evaporated milk and it was nice and creamy. I also used a combination of sharp cheddar, monterey jack and a small amount of velvetta as that's what I had on hand. Makes a wonderful, creamy mac and cheese. My family likes to spice things up a bit so after reserving some for children in the group, I added white pepper, red pepper flakes and a tiny bit of garlic powder. Yum!!!
My crock pot is too small. Can I bake in oven? How long and what setting? Thanks.
Hi Marie, you may want to try my recipe for No-Boil Mac and Cheese. It's an oven recipe. 🙂
Super easy to fix and delicious! I followed the recipe except that I added a dash of dry mustard and more salt & pepper for seasoning and used American cheese slices instead of block white American cheese.
I made a double batch of this for the Fourth of July cookout and there wasn’t any left!! It was amazingly creamy and delicious. One bad thing: after sitting on low in the crock pot for 2 hours the cream sauce got a bit dry/not creamy. I was told to put more butter in next time to avoid that but I’m just thinking we need to eat it much sooner 😉
Made this for my yearly bbq where I also have a big crowd. It was very easy to put together and everyone loved it. I doubled the recipe and my guests even took home some of the leftovers. When reheating the leftovers I had I heated on the stove and added a splash of half and half and it was nice gooey again. I will make this again.
This was a HUGE hit! Thank you!!
Made this for a pot luck at work and was a huge hit! Such an easy recipe, this will be my go to from now on! Thank you!
I needed to decide on a dish for a pot luck lunch at work. Several meat and tomato sauce dishes were already on the list, so I decided to try a mac and cheese. Well, as much as my family loves mac and cheese, I have never made it home made. So I went searching and came across many different recipes, but for some reason, this one hit me as looking delicious. We were not disappointed. Everyone loved it. I made the pasta and mixed in the butter the night before, refrigerating it until morning. Before leaving for work, I put everything in the crock pot, Plugged it in when I got to the office and it was ready to eat in a couple of hours! I can't wait to make this for my family!
Love hearing that. Glad you enjoyed the ease of making it. Can't wait to hear how much your family enjoys it.
Amazing!
I made this without cooking the elbows cause we were camping and its a pain to boil water and it came out great
Great to know for the future! Thank you!
We are on a grain free diet. I was wondering if i can use spaghetti noodles ? I don't have the attachment to make macaroni noodles.
Should I drain the noodles before putting it in the slow cooker?
Steph, yes. ????
Do you think I could put some cream cheese in this? Or sour cream?
Hello, I've made many of your recipes and they have all been amazing! I am in charge of bringing Macaroni & Cheese to my in-laws on Thanksgiving and am trying to find the best recipe to feed roughly 20 people. I saw in the comments where you had mentioned that the best way to double this recipe may be to cook it in separate crock pots, would it work if I was to make two separate batches and put one in a foil pan while the other cooked? And mix the two back in the crock pot to keep warm? And would it be possible to add in shredded pepper jack cheese along with the cheddar and white American? Sorry for all the questions & thank you for your help and amazing recipes!
Update- made two separate batches and kept both warm in the crock pot. The recipe was a hit, everyone commented that it was great! Thank you again for your recipes!
I have made many, many Country Cook recipes over the last 3 years. Some are requested faves every holiday (the Southern praline pecan cake is one that I just made for Thanksgiving at work!). I just made this one for the first time (I usually make the no boil macaroni and cheese). This one is another winner! However, I did let the woman at the Publix deli talk me into different cheeses and she did not steer me wrong! I used 1/4 lb. each of white American, havarti, smoked gouda and aged asiago in addition to the cheddar. Followed everything else as written. Omg. It is amazing!! Try it, Brandie! I feel like I know you. LOL You won't regret It!
Hi Mandi! Thank you SO very much! I just loved reading your comment! I love that she talked ya into some different cheeses. I love ALL of those so I will definitely have to give it a try! Thank you for sharing!!
This recipe is just amazing. I made it today for a test run before the holidays, and let me say it’s DELICIOUS! The Mac is very creamy and flavorful! Definitely making this for the holidays. Just need to get a bigger Crock Pot to serve more people.
Hi Jesus!! Yay! I really appreciate you coming back to let me know what you thought! So happy you love this one as much as we do. Happy Thanksgiving!
This seems just perfect! Thanks for the recipe! Any thoughts on using heavy cream instead of half and half?
I made this last year, guys and let me tell y'all...it was a huge hit!! Even better was the easiness of it for the already frazzled Thanksgiving cook! Making it again this year!
You are so sweet to come back and let everyone know your thoughts! Thanks again Karen!
I want to double this to use at a school banquet. Do I need to increase cook time? Thanks!
I have a huge guest list for Thanksgiving this year, so i wondered the same thing. Can we double it?
Hi Karen! You can. In all honesty, I would probably just use two separate slow cookers. That will make sure everything cooks/melts evenly. Hope that helps!
i wonder how this would work with gluten free noodles? any thoughts
I like my Mac & Cheese a little more creamier. How much more Evaporated Milk and Half & Half should I use?
I made this recipe exactly as it is listed, and it seemed a bit bland for me. I added two small cans of mild diced chillies and it came out amazingly. What flavor! This will now be my go to recipe 🙂
I made this for our 4th of July cookout and it is great. Thanks for sharing.
How long can I leave it on low after cooking. Trying to figure out if I should cook it and leave on low during church or cook it while church is going on. I wouldn't be able to stir it as much if cooking while church is going.
Has anyone ever made this with jus regular 2% milk instead of half & half?
I found this via Pinterest 🙂 would I be able to freeze the leftovers? Then later thaw and bake in the oven ornate example?
I did not make this recipe yet but am going to give to a friend. I have a catering business and I will make extra when we make it for a job and I will freeze for our family for later use. You can slow cook it frozen or thaw first but you will need to add milk or water as the noodles will have sucked up some of the liquid. I prefer water but either is fine.
anyone ever make this with only american cheese? I am not a huge fan of cheddar
Claudia - a mild cheddar would work great but you could certainly go with American 🙂
Do you cook the macaroni before placing it in crockpot or do you put it in uncooked?
Step one gives directions for the macaroni - "Cook the pasta according to the package directions until al dente . .(should still have a little 'bite' to it.)
Whole box (16 oz) or measuring out 12ounce?
Hi! This looks perfect for the party I'm hosting before Christmas. Question for you: I am not a fan of mushy pasta. Does the pasta retain a classic aldente or should I undercook it by half the time? For example, I never add the pre cooked pasta to a soup until the very last minute just to warm it before serving. Any help appreciated!
I undercooked the pasta by about a minute or so. I thought the consistency came out great, but you could probably undercook by half the time so it would be more al dente.
Hi! Can you make this recipe in a 6 quart slow cooker?
I made it using a 6qt slow cooker and did 1.5x the recipe. I easily could have doubled it though. Came out delicious!!
Needed a mac 'n cheese recipe for my son's Friendsgiving at school. This crock pot version sounds like the perfect recipe! I also have a clogged bathroom drain....thanks for solving both of my dilemmas! Thanks for your post! Have a great Thanksgiving!
Ha - I love it (well, not the part about you having a clogged drain!) 🙂 Hope you love this mac & cheese recipe!!
We're going camping and this came along at the right time. How do you think this would be with the cheddar, baby Swiss, & a Parmesan, Romano and asiago blend? Cause I've got that already
I say go for it, make it your own! It should work just fine.
This looks so delicious! The fact I can make this in a slow cooker is even better because I always make it from scratch on the stovetop and it takes foooreevver. Thanks for this - thanksgiving dinner just got a little easier 🙂
My job is done!! Yes, this does cut out a lot of work. Hope you enjoy 🙂
