Ingredients

Units Scale

For the Mac and Cheese:

  • 16 oz elbow macaroni (or shells, cavatappi)
  • 1 can (12 oz) evaporated milk
  • 2 cups whole milk
  • 1 cup heavy cream
  • 1/2 cup unsalted butter, melted
  • 3 cups sharp cheddar cheese, shredded
  • 1 cup Monterey Jack cheese, shredded
  • 1 cup Velveeta, cubed (optional, for extra creaminess)
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon salt (adjust to taste)
  • 1/2 teaspoon black pepper

Optional Mix-Ins:

  • 1/2 cup cooked bacon, crumbled
  • 1/2 cup diced jalapeños
  • 1/2 cup toasted breadcrumbs or crushed Ritz crackers for topping

Instructions

1. Cook the Pasta:

  • Boil the macaroni for about 4 minutes—just until slightly softened.
  • Drain and set aside (it will finish cooking in the slow cooker).

2. Prepare the Cheese Sauce:

  • In a large bowl, whisk together evaporated milk, whole milk, heavy cream, melted butter, and seasonings.
  • Stir in the shredded cheese (reserving 1/2 cup for topping).

3. Combine in the Slow Cooker:

  • Add the partially cooked pasta to the slow cooker.
  • Pour the cheese mixture over the top and stir to combine.

4. Cook on Low:

  • Cover and cook on LOW for 2-3 hours, stirring occasionally to prevent sticking.
  • The cheese will melt into a luscious, creamy sauce.

5. Serve and Enjoy:

  • Stir well before serving.
  • Sprinkle with additional shredded cheese or toasted breadcrumbs for extra texture.

Notes

  • Don’t Overcook the Pasta: Since it continues cooking in the slow cooker, undercooking it slightly beforehand prevents mushiness.
  • Stir Occasionally: This keeps the cheese sauce smooth and prevents sticking.
  • Use a Blend of Cheeses: Different cheeses add depth of flavor and ensure a creamy texture.
  • To Keep Warm: Switch the slow cooker to “Warm” after cooking to maintain the perfect serving temperature for hours.
