What’s in Crockpot Mac n Cheese?
This creamy crockpot mac and cheese is one of my favorite set-it-and-forget-it recipe for dinners or side dishes. I just love the mix of cheese, heavy cream, and sour cream to create that super creamy texture and cheesy flavor!
- Pasta: The classic elbow macaroni noodle is ideal, but you can actually use other short pasta shapes too.
- Butter: Use salted butter, and cut it into cubes to help it melt evenly.
- Cheddar Cheese: Gives this dish that classic cheesy flavor.
- Eggs: Add richness, making the dish smooth and creamy.
- Sour Cream: I like to use light sour cream, or you could substitute plain Greek yogurt.
- Condensed Cheddar Cheese Soup: This is the secret to the cheesiest mac and cheese you’ll ever taste!
- Heavy Cream: This helps create a nice creamy texture.
- Milk: Whole milk is great for this dish, but other milk types are fine.
- Dry Mustard Powder: Enhances the savory and umami flavor of the dish.
- Salt + Pepper: Enhance the cheesiness!
Pro Tip: I love to freshly shred the cheddar cheese for the best results. Pre-shredded cheese will not melt as well.
Variations on Slow Cooker Mac and Cheese
There are so many ways you can get creative with this crockpot macaroni and cheese recipe. Add some crumbled cooked bacon and caramelized onions, pesto, Buffalo sauce, or taco meat for a different flavor.
You can try adding some garlic powder, and swap out the cheddar for a mix of Parmesan and mozzarella to create garlic Parmesan mac and cheese.

Nutrition Information
Classic cheddar cheese is perfect for this recipe, but you can add other types of cheese if you prefer. Pepper jack adds some spice, or you can use a white cheddar.
I prefer a mixture of regular milk and heavy cream. Evaporated milk can turn your mac and cheese gooey or sticky.
Mustard is slightly acidic and spicy, which enhances the overall umami flavor of the mac and cheese. I promise, you won’t taste it!
Not in this case! Slow cooking helps to thicken the cheese sauce over time.
I prefer to cook my mac and cheese in a mixture of milk, heavy cream, and condensed cheddar soup. It helps the pasta absorb even more flavor.
Cook this dish covered in the crockpot for the best results. Otherwise, it may dry out.
If you used pre-shredded bagged cheese, it may not stick well to the pasta because of the starches added to prevent the cheese from clumping in the bag. I always recommend shredding your own cheese for this recipe!
My husband “loved” this Mac n cheese! He said best ever and should make for the grand kids as they are Mac n cheese lovers! However, if you can help with one issue. At 1.5 hours in crockpot it is very creamy but just not warm enough and needs to thicken so I went the extra 30 minutes for a total of two hours in the crockpot. This thickened the runny sauce but then it was clumpy. I did shred my own block of cheddar. Any suggestions so it does not clump?
Hi Linda, if the cheese starts to clump, that’s a good indication that it has overheated in the crockpot. Try cooking for less time!
Every slow cooker mac or instant pot mac n cheeese has come out stringy.. what makes yours different?
Hi Greg, I’m wondering if you’re using pre-shredded cheese? Pre-shredded cheese is coated in starch to prevent it from sticking together in the bag, and this can cause irregular melting and stringiness in the final product. I highly recommend shredding your own cheese for this recipe!
Just curious, does this have to cooked in the crockpot? Or can it be eaten without the 2 hours in the crockpot?
You can also make it on the stovetop! It just needs enough time for the sauce to cook down and thicken.
Why the eggs? I’ve never seen eggs in a Mac & cheese recipe before and I’d worry about eggy bits (sorry for me that’s a huge no!) Haven’t tried it yet, just wanted to know the reason for the egg.
Hi Cathie! Eggs do seem a bit out of place in Mac and cheese if you’ve never tried it, but you won’t know they’re there. Beating and mixing them into the sauce essentially creates an emulsion, which makes the cheese sauce as smooth and creamy as possible. You can certainly leave them out if you prefer, but it will change the texture a bit (though it will still taste good).
