Ingredients to Make Slow Cooker Mac and Cheese

Y’all, here’s a quick peek at the key ingredients you’ll need to whip up this recipe. Make sure to peep the full recipe card below for the complete rundown and all the precise amounts you’ll need!

• Cheese: This recipe has a variety of cheeses for their different flavor profiles and melting textures. Cheddar has a deliciously buttery sharp flavor that lends itself well to pasta noodles.  The sharpness of cheddar comes from how long the cheese is aged.  The longer it is aged, the sharper it will taste.  You can choose which you prefer. Gruyere is a hard Swiss cheese that has a mix of salty and sweet nutty flavors that help to balance the sharpness of the cheddar.  Last, we’re using good ole American cheese (just trust me on this boos).
• Elbow macaroni: The classic pasta shape for mac and cheese but you can easily make it with any small pasta shape you prefer.
• Milk: We will be using a combination of whole and evaporated milk to create a creamy cheese sauce for the macaroni and cheese.
• Worcestershire sauce: Adds savory flavor to the cheese sauce.
• Dry mustard: Adds a bit of nutty, earthy flavor.
• Butter: For toasting the panko bread crumbs. I recommend using unsalted butter to avoid adding additional saltiness to the dish.
• Panko crumbs: These Japanese-style breadcrumbs add crunchiness to the mac and cheese giving it that baked mac and cheese feeling.

How to Make Crock Pot Mac and Cheese

This section should go by pretty quickly because when I say this recipe is easy, I ain’t kidding!  This slow cooker mac and cheese recipe, like most slow cooker recipes, comes together in a flash boos.

Step 1: Cooking the Macaroni and Cheese

1. Spray your crockpot or slow cooker with non-stick spray.  This step makes clean-up a breeze.
2. Place the macaroni, cheeses, and milks in your slow cooker after spraying it. 
3. Stir everything together.
4. Cover with the lid and turn on the slow cooker to cook.
5. Add the Worcestershire sauce, mustard, salt, and pepper when it’s close to the end of the cooking time.
6. Stir together and continue cooking until it’s done.

Step 2: Making the Crispy Topping

1. Melt the butter and add the panko crumbs to toast them.
2. Sprinkle the toasted breadcrumbs over the top of the dish before serving.

Tips for Making the Best Slow Cooker Macaroni and Cheese

• Use Blocks of Cheese. While pre-shredded cheese feels easy they are loaded with chemicals.  Freshly grated block cheese will taste more flavorful. You can easily shred them yourself by hand or using your food processor with the grating blade.
• Don’t Skip the Breadcrumbs. Yes, it’s completely optional but it adds a nice contrast to the creamy cheesy pasta.
• Make Sure You Spray Your Crock Pot. This dish is pretty cheesy and messy but spraying the slow cooker liner will make the clean up after much easier.
• Check the Pasta During Cooking. Not all slow cooker brands cook the same so be sure to check it at various points in time just in case your pasta cooks faster. You don’t want to overcook the pasta.
• Doubling the Recipe. It’s easy to make this dish in larger quantities but make sure you use a larger (6 quart) slow cooker. Try to avoid filling over two-thirds full. When making double batches you may need to extend the cooking time.

Popular Substitutions & Additions

• Use Different Cheeses. Yes, you can swap the cheese if you prefer different flavors. Play around with a combo you enjoy. Just don’t eliminate the American cheese.
• Spicy Mac and Cheese. I love a little spice. If you want to add a bit of heat, you can throw in some hot or buffalo sauce or swap the gruyere cheese for pepper jack.
• Add Veggies. This is a fab trick for getting my picky eaters to eat a few veggies. Just add in some blanched vegetables such as broccoli, cauliflower, or thawed frozen peas in the last hour to keep them tender and not mushy.
• No Panko Crumbs. If you don’t have them, crush some crackers and sprinkle over the top instead.

What to Serve with Slow Cooker Mac and Cheese

• Make it Southern: Pair it with these favorites: Fried Pork Chops, Smothered Pork Chops, Buttermilk Fried Chicken, or Classic Pot Roast.
• Sides: Enjoy it with fluffy Buttermilk Biscuits, Turnip Greens, Collard Greens, Fried Okra, and Fried Green Tomatoes.
• Holidays: Enjoy them with your favorite turkey including Fried Turkey, Turkey Chops, Turkey Gravy, and these Turkey Legs.

How to Store & Reheat Crock Pot Mac and Cheese

Allow the mac and cheese to cool to room temp. This will keep it from sweating in your storage and making it soggy. Once it’s cooled, transfer the mac and cheese to an airtight container.

I personally like to store the breadcrumb topping separately from the cheesy pasta. If you know from jump that you will probably have leftovers, I suggest adding that topping just to the amount you will be serving. Store the rest so it stays crunchy.

Reheat leftovers in the oven at 350°F (175°C). Place the mac and cheese in an oven-safe dish. If you’ve stored the breadcrumb topping separately, sprinkle it on top now. Cover with aluminum foil to prevent the top from burning and to help retain moisture. Cook for 15-20 minutes, or until heated through and the breadcrumb topping is crispy again.

If the breadcrumb topping isn’t crispy, you can remove the foil and broil for an additional 1-2 minutes. Watch closely so you don’t let it burn up!

How long will crock pot mac and cheese last in the fridge?

When stored properly it will keep in the fridge for up to 3 days.

Can I freeze slow cooker mac and cheese?

No, I don’t recommend freezing this boos. Dairy often breaks when it’s frozen so when you thaw it out again the cheese sauce can be a bit grainy instead of creamy. Also, the pasta will often thaw out with a much softer texture.
