Slow cooker mac and cheese is a creamy, cheesy, indulgent recipe that is easy to make and comfort food your whole family will love. The rich and cheesy flavors from the sharp cheddar cheese and Gruyere is a delicious combination that will make you smile with every bite.
My slow cooker mac and cheese becomes smooth and velvety when cooked slowly using the low heat setting. It’s the perfect dish for game day, family gatherings, or a potluck dinner. My easy-to-make creamy crock pot mac and cheese recipe is definitely a crowd-pleaser!
I love using a slow cooker to make mac and cheese. It frees up oven space and makes the cooking process easy. You can also use this recipe to make stovetop mac and cheese. Just make sure to let the cheese melt so the sauce gets a smooth, creamy texture.

Ingredients to make Slow Cooker Mac and Cheese
Let’s start by gathering the ingredients we need to make our recipe. In Chef Speak, this is called the Mise en Place, which translates into Everything in its Place.
Not only does setting your ingredients up ahead of time speed the cooking process, but it also helps ensure you have everything you need to make the dish.
Can I use different cheese to make this Slow Cooker Mac and Cheese Recipe?
You certainly can. I’ve made mac and cheese using a variety of cheese over the years. In my younger days, I loved using American cheese and Velveeta cheese. They melt really well, and you end up with a very creamy cheese sauce.
You can also use a combination of cheese to make this recipe. Some of my favorites are Gouda, Monterey Jack cheese, Colby Jack, fontina, and cream cheese or mascarpone. For a spicer flavor, you can use pepper jack cheese.
You can also add a little parmesan cheese (or romano) to give mac and cheese a little boost of flavor.
*Another tip is that pre-shredded cheese won’t melt, as well as shredding your own cheese from blocks. An anti-clump agent is added to pre-shredded cheese.
Can I add other ingredients to the mac and cheese?
Absolutely. You can add shredded or chopped chicken, pulled pork or cooked hamburger to the recipe. I like adding buffalo chicken and bleu cheese. Another family favorite is adding barbecue sauce to pulled pork and mixing that into the noodles.
You can also add broccoli, peas, spinach (or your favorite greens), mushrooms, or cauliflower to the mixture. You need to par-cook the veggies before adding them.
You can also change the seasonings to your taste preference. Adding a little dry mustard will perk up the flavor. And if you like heat, add a little red pepper flakes.

Am I reading this right? Do you preheat the slow cooker for 2-1/2 hours? Why?
