  • 1 pound elbow pasta uncooked (regular, not gluten free)
  • 2 1/2 cups milk whole is best
  • 12 ounces evaporated milk
  • 12 ounces Sharp cheddar 3 cups shredded
  • 4 ounces American cheese (or Monterrey) 1 cup shredded (from the deli, not processed slices)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon dry mustard
  • 1/4 teaspoon garlic powder
  • Dash of cayenne pepper to taste
  • 1/4 cup butter cubed


  • Spray 6-quart slow cooker with non-stick spray.
  • Rinse the uncooked pasta well in cold water and drain.
  • Add uncooked pasta to crockpot along with milks, cheeses, salt, pepper, mustard, garlic and cayenne pepper. Stir to combine, making sure macaroni is submerged in liquid as much as possible.
  • Dot with cubed butter.
  • Cover and cook on low heat for 1 hour. Remove lid and stir. Depending on your slow cooker, your dish could be done at this point or require UP TO 1-2 more hours.
  • If not done, continue cooking and checking periodically (ever half hour or so).
  • When done, pasta will be tender and liquid will be thick and creamy.



IMPORTANT - please do not use the bagged shredded cheese. It contains an anti-caking agent that can make your mac and cheese gritty. Get the cheese from the deli and shred it yourself. 
Also, every slow cooker is different. Newer slow cookers should work fine for this recipe. Cook on low for one hour without disturbing. Remove lid and stir well. Replace lid and check after 30 more minutes. DO NOT turn the heat up! You will make your macaroni mushy. 
My slow cooker is only a couple years old and my mac and cheese is done after about 1 hr and 45 minutes.
