This creamy crockpot mac and cheese starts with uncooked elbow pasta; no boiling these noodles. Simply throw the milk, cheese, and seasonings in the slow cooker for a meal everyone will love!

We've also made homemade stovetop macaroni and cheese and baked macaroni and cheese, but the slow cooker is super portable and the dish won't dry out. This is a great casserole to take to a potluck or family get together.

Creamy Crockpot Mac and Cheese

There are lots of different ways to make mac and cheese, but two of them are more popular than others. The first type is southern or baked mac and cheese, which includes eggs and is almost like a casserole. The second type is cooked on the stovetop in a béchamel sauce. There are no eggs and it is super creamy.

In order to get that ultra creamy texture in a crock pot, you either have to use condensed cheese soup or Velveeta cheese, neither of which appealed to me.

The next best thing is to use evaporated milk and American cheese, the kind you get from the deli counter. Barring American cheese, using a melty cheese like Monterey Jack or White American will also produce creamy results.

If you are making for the holidays

If you've never made this before, please do a dry run before the holiday! Everyone's slow cooker acts differently, so it's important to try this out first. Please read through the FAQ below as well for best results. Happy Thanksgiving and Merry Christmas!

Frequently Asked Questions

There have been quite a few questions on this recipe, please check here before asking in the comments as it may already have been answered. PLEASE READ the notes in the printed recipe.

Can I double this recipe and does it change the cooking time?

Yes, this recipe can be doubled provided you have a large enough slow cooker. The cooking time will not change.

The recipe says to use uncooked noodles, however, it also says to rinse the pasta?

Yes, rinse the uncooked pasta simply to remove any dust and foreign particles from the manufacturing plant.

I don't eat yellow cheese, what is a good white substitute?

Monterey Jack works well, as does White American and White Cheddar. A marble cheese should work as well. Sharp cheddars will give this dish the best flavor, try Vermont white sharp cheddar!

Can I make this ahead and reheat it?

We don't recommend reheating macaroni and cheese as it never tastes quite the same and there's a possibility that the macaroni will become mushy. However, if this is a deal breaker, you can reheat it – simply add some milk to loosen the thickened sauce while reheating. We recommend making it and having it ready right before you leave. Turn off the slow cooker but leave the lid on. When you arrive stir it and loosen with milk if needed.

How many servings does this make?

This serves 6-8 people. A serving size is 2 ounces of dry pasta which expands to approximately 1.5 cups with sauce when cooked.

Why was my mac and cheese gritty?

Prepackaged shredded cheese contains an anti-caking agent that can cause your final product to taste gritty. Purchase your cheese from the deli and shred it yourself. We've also discovered that some less expensive cheeses are gritty even when you shred them yourself, but after the mac and cheese sits for a while the grittiness goes away.

Why was my mac and cheese mushy?

If it cooks too fast or too long it will get mushy. The biggest culprit is an older slow cooker that may cook hotter (even on low) than a newer crock pot. Leave the lid on for one hour on low. DON'T increase the temp to High! Stir after one hour then check after 15 more minutes. Check and stir every 15 minutes after that if needed. Mine was done is 1 hour and 45 minutes.

Mushy mac and cheese can also be the result of using gluten free macaroni noodles as they do not hold up as well. One of our readers made this successfully with gluten free pasta. she said hers was done in 90 minutes but began to get mushy at 2 hours, so it's important to keep an eye on it!

Can I mix all of the ingredients, refrigerate overnight, and put in the crockpot a few hours prior to serving?

Yes, with the exception of the pasta. Wait until you take it out of the fridge and are turning the slow cooker on before you add the macaroni.

I'm confused by the cooking time, is it 2 hours or 3?

Actually, it's up to 3 hours. You should cook the dish on low for 1 hour, then stir it and check for doneness. After that, check it periodically (every thirty minutes or so) until it is done. The actual cooking time is completely dependent on the slow cooker you have (similar to ovens, they all cook differently), hence the "up to 3 hours" instruction.

Can I use regular milk instead of evaporated milk?

Don't use regular milk. However, you can create your own evaporated milk. To make 1 cup of evaporated milk, simmer 2 1/4 cups of regular milk down until it becomes 1 cup.

Is evaporated milk the same as condensed milk?

Condensed milk is sweetened and the two cannot be used interchangeably.

Ingredients you will need for crockpot mac and cheese:

1 pound elbow pasta
2 1/2 cups milk (whole is best)
1 can (12 oz) evaporated milk
3 cups (12 oz) shredded sharp cheddar
1 cup (4 oz) shredded American cheese (or Monterrey)
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dry ground mustard
1/4 teaspoon garlic powder
Dash of cayenne pepper (to taste)
1/4 cup butter, cubed

Helpful kitchen tools:

6-quart slow cooker
Food processor with shredder
Liquid measuring cup
Measuring spoons

To keep our mac and cheese from being bland we added mustard, garlic, and cayenne to ours in addition to the basic salt and pepper. These can all be adjusted to your taste.

Calories: 574

▢ 1 pound elbow pasta uncooked (regular, NOT gluten free, NOT quick cook pasta)
▢ 2 1/2 cups milk whole is best
▢ 12 ounces evaporated milk
▢ 12 ounces Extra sharp cheddar 3 cups shredded (from the deli, shred yourself, don't buy bagged)
▢ 4 ounces American cheese (or Monterrey) 1 cup shredded (from the deli, not processed slices)
▢ 1 teaspoon salt
▢ 1/2 teaspoon black pepper
▢ 1/2 teaspoon dry mustard
▢ 1/4 teaspoon garlic powder
▢ Dash of cayenne pepper to taste
▢ 1/4 cup butter cubed

Spray 6-quart slow cooker with non-stick spray.
Rinse the uncooked pasta well in cold water and drain.
Add uncooked pasta to crockpot along with milks, cheeses, salt, pepper, mustard, garlic and cayenne pepper. Stir to combine, making sure macaroni is submerged in liquid as much as possible.
Dot with cubed butter.
Cover and cook on low heat for 1 hour. Remove lid and stir. Depending on your slow cooker, your dish could be done at this point or require UP TO 1-2 more hours.
If not done, continue cooking and checking periodically (ever half hour or so).
When done, pasta will be tender and liquid will be thick and creamy. Sauce will thicken even more after lid is removed and mac and cheese sits.

IMPORTANT – please do not use the bagged shredded cheese. It contains an anti-caking agent that can make your mac and cheese gritty. Get the cheese from the deli and shred it yourself.
Also, every slow cooker is different. WNewer slow cookers should work fine for this recipe. Cook on low for one hour without disturbing. Remove lid and stir well. Replace lid and check every 15 minutes after that. DO NOT turn the heat up! You will make your macaroni mushy. My slow cooker is only a couple years old and my mac and cheese is done after about 1 hr and 45 minutes.
For BEST RESULTS be sure to read the Frequently Asked Questions in the blog post before making your mac and cheese.
