Rich, creamy, and completely hands-off, this Slow Cooker Mac and Cheese uses a four-cheese blend for the smoothest, most comforting sauce. Just cook the pasta, add everything to the crockpot, and let it do the rest.

Instructions
Bring a large pot of salted water to a boil. Cook the elbow macaroni for 5 to 6 minutes, until just al dente. It will continue cooking in the slow cooker. Drain well and set aside.
Lightly spray the slow cooker insert with cooking spray.
Add the drained pasta, whole milk, evaporated milk, Colby Jack, Velveeta, cream cheese, butter, salt, pepper, and ground mustard to the slow cooker. Reserve ½ cup of the shredded cheddar for the end — add the rest now. Stir until everything is well combined.
Cover and cook on LOW for 2 hours, stirring at least once every hour. The sauce may look a little loose when you stir, which is normal. It will thicken as the pasta absorbs the liquid and the cheeses melt together.
After 2 hours, sprinkle the reserved ½ cup of shredded cheddar evenly over the top. Replace the lid and cook for 3 more minutes, until the cheese is melted.
Give it a good stir and serve straight from the slow cooker.
Notes
Cooking Tips
Cook pasta just to al dente (about 5 to 6 minutes) — it will continue cooking in the slow cooker. Overcooking it first leads to mushy mac.
Always shred cheese from the block. Pre-shredded cheese contains an anti-caking agent that prevents smooth melting and can cause a grainy sauce.
Cook on LOW only. HIGH heat can cause the dairy to separate and the cheese sauce to turn grainy.
Stir at least once an hour so the cheese melts evenly and doesn't stick to the sides.
Substitutions
Velveeta can be swapped for American cheese if preferred.
Mild cheddar can be replaced with sharp cheddar for more bite.
Evaporated milk is recommended for the creamiest sauce, but whole milk can be used in a pinch — the sauce may be slightly thinner.
Storage and Make-Ahead
Refrigerate leftovers in an airtight container for up to 4 to 5 days.
Freeze for up to 3 months. Thaw fully before reheating.
Reheat on the stovetop with a splash of milk over medium-low heat, or microwave at 50% power in 1-minute intervals, stirring between each.
To keep warm for a potluck or party, switch to WARM setting after cooking. Stir before serving and add a splash of milk if the sauce has thickened.
