How to Make Slow Cooker Mac & Cheese

Step 1: Cook the Pasta

Start with al dente elbow pasta because it will continue to soften in the slow cooker. Follow the package instructions carefully and rinse once done to stop the cooking process. Setting pasta aside now ensures it holds its shape and texture in the final dish.

Step 2: Make the Cheese Sauce

In a large skillet over medium heat, melt the butter until foamy and fragrant. Add shredded cheddar and mozzarella cheeses gradually, stirring constantly so they melt evenly into a smooth, velvety sauce. This step is where the magic of that luscious cheese base begins.

Step 3: Combine Ingredients in the Crockpot

Transfer your glossy cheese sauce to the slow cooker pot and add sour cream, cheddar cheese soup, and the cooked pasta. Stir gently to blend all those cheesy delights together. Then pour in milk alongside salt, mustard powder, and paprika—these seasonings brighten the dish and deepen its flavor layers. Stir everything thoroughly so each piece of pasta is lovingly coated.

Step 4: Cook in the Crockpot

Set your crockpot to low and let the mac and cheese cook slowly for 2 hours. Stir occasionally; this helps the cheese meld together with the pasta evenly and prevents sticking. The slow heat encourages the sauce to thicken beautifully without drying out.

Step 5: Serve and Enjoy

Once the two hours are up, your Slow Cooker Mac & Cheese will be bubbling, cheesy, and inviting. Serve it straight from the crockpot while it’s hot and gooey, savoring every creamy spoonful that’s packed with homey goodness.
