Macaroni & Cheese in the Slow Cooker

Fall is in full force which means bring on all the hearty comfort foods! Once the cooler weather hits, my kids crave for a giant bowl of mac & cheese regularly. They love a classic baked macaroni and cheese but with the busy school season we’ve had so far, we’ve been using our slow cooker a lot lately. This version couldn’t be easier since everything cooks right in the crock pot – even the pasta.

You can boil the pasta first if you prefer but I chose to keep things simple by throwing the uncooked macaroni together with the rest of the ingredients. For the cheeses, I used sharp cheddar and Monterey jack. They both melt so well! Slow cookers vary by brand and size, so be sure to keep your eye on this and stir every so often so that the pasta cooks evenly. Mine was perfectly al dente around 90 minutes in a 6-quart cooker.

Ingredient List

Trust me, you’re going to want to add in each of these ingredients so your crockpot mac and cheese turns out perfectly. Don’t be surprised if this becomes your new favorite mac and cheese recipe! It will win you over with its flavor and how easy it is to make.

Elbow Macaroni: To soak up all that cheesy goodness.

Unsalted Butter: Butter adds creaminess and flavor. It’s a must for rich and velvety mac and cheese.

Cheddar Cheese Soup: Makes the sauce creamy and super cheesy.

Half and Half: Half milk, half cream. It makes everything smooth and rich. If you don’t have half and half you can substitute it for 1 ¼ cups whole milk and 1 ¼ cups heavy whipping cream. You can also use whole milk, but your mac and cheese won’t turn out as creamy.

Evaporated Milk: So the sauce is even more creamy and delicious.

Shredded Sharp Cheddar Cheese: The star cheese that brings all the flavor. Save some for the topping, too!

Shredded Monterey Jack Cheese: A milder, smooth cheese that goes perfectly with the cheddar. Some other cheeses that you can try using are gruyere, colby jack, and gouda!

Sour Cream: Tangy and creamy, it gives a little zing to the sauce and makes it even more irresistible.

Salt, Black Pepper, and Garlic Powder: These are your main seasonings. Salt for the taste, pepper for a tiny kick, and garlic powder for a savory twist.

Freshly Chopped Parsley: Adds a pop of color and a bit of freshness to your slow cooker mac and cheese. I love garnishing my pasta dishes with fresh herbs!
