Why You’ll Love This Crockpot Mac and Cheese
This recipe delivers a creamy texture and bold cheesy flavor without fuss. It cooks in just about two hours, serves eight people generously, and stays hands-off once you load the slow cooker. As a result, it makes the perfect side dish for holidays, potlucks, or casual family dinners. Plus, leftovers (if there are any) can be saved for later.

Key Ingredients for the Best Flavor
Pasta Choice
Sturdy elbow pasta makes all the difference here. Thin noodles or quick-cook versions fall apart quickly and create mush. Brands like Barilla or Creamette hold up best during slow cooking.
Cheese Selection
Sharp cheddar brings depth while American cheese melts silky smooth. Shred both from the deli counter yourself since pre-shredded cheese includes additives that turn the sauce gritty.
Milk and Cream Base
Whole milk mixed with evaporated milk gives the sauce body and richness. Skim or low-fat milk results in a watery finish, so stick with whole milk for guaranteed creaminess.
Seasonings & Extras
Dry mustard and garlic powder deepen the flavor, while a tiny pinch of cayenne pepper adds a gentle warmth. Cubed butter melts slowly into the sauce, making it luxuriously smooth.
Step-by-Step Instructions
Prep Your Slow Cooker
Spray your six-quart slow cooker with non-stick spray. Rinse the uncooked pasta in cold water, then drain it well to stop the starch from clumping.
Combine Ingredients
Pour the pasta, milk, evaporated milk, shredded cheeses, salt, pepper, mustard, garlic, and cayenne into the slow cooker. Stir until the noodles are submerged. Scatter the cubed butter over the top.
Cook Low & Slow
Cover and cook on low for one hour. Stir, then replace the lid. Depending on your cooker, the mac and cheese may finish now or may need up to two more hours. Stir every 30 minutes after the first hour.

How to Tell It’s Done
The dish is ready when the pasta is tender and the sauce thickens to coat the noodles. The sauce will continue to thicken slightly as it cools uncovered.
Tips for Success
Always buy deli cheese and shred it yourself. Pre-shredded cheese leads to a grainy sauce.
Keep the heat on low at all times. Switching to high causes uneven cooking.
Test your pasta brand before a holiday dinner to avoid mushy surprises.
If using gluten-free pasta, check at 90 minutes since it cooks faster.
Remember, each slow cooker runs differently, so treat the timing as a guide.
FAQs About Crockpot Mac and Cheese
Can I double the recipe?
Yes, if you use a larger slow cooker. The cook time remains the same.
What cheese substitutes work best?
Good swaps include Muenster, White American, White Cheddar, or Vermont sharp cheddar.
Can I reheat leftovers?
Yes, but the pasta may soften more. Add a splash of milk before warming to loosen the sauce.

Notes
Do not use bagged shredded cheese (anti-caking agents cause grittiness). Buy deli cheese and shred yourself.
Use sturdy pasta brands like Barilla or Creamette. Thin noodles will cook too fast and get mushy.
Gluten-free pasta works but gets mushy quickly (done in ~90 minutes).
Cook only on low heat; do not switch to high.
Each slow cooker cooks differently; total cook time may range from 1 hr 45 min to 3 hrs.
For holidays, test the recipe beforehand since cookers vary.
Doubling recipe works with a larger slow cooker; cook time unchanged.
White cheese substitutes: Muenster, White American, White Cheddar, or Vermont sharp cheddar.
Avoid reheating if possible; reheated mac and cheese can become mushy. If reheating, add milk to loosen sauce.
Grittiness may come from pre-shredded cheese or cheaper cheeses.
To substitute evaporated milk: simmer 2 ¼ cups regular milk until reduced to 1 cup (cannot use condensed milk).
Whole milk required for recipe (lower-fat milk makes sauce watery).
