  • 2 cups mozzarella cheese, shredded
  • 1/2 cup unsalted butter, melted
  • 3 cups whole milk
  • 2 1/2 cups half-and-half
  • 1/4 cup all-purpose flour
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon garlic powder
  • Salt and pepper to taste

Optional Add-ins:

  • Cooked and crumbled bacon
  • Sautéed onions
  • Diced tomatoes
  • Chopped fresh herbs (parsley or chives)


  1. Prepare the Macaroni:
    • Cook the elbow macaroni according to the package instructions until al dente. Drain and set aside.
  2. Shred the Cheese:
    • Shred the sharp cheddar and mozzarella cheeses using a grater. Combine them in a bowl and set aside.
  3. Create the Cheese Sauce:
    • In a saucepan, melt the butter over medium heat. Stir in the flour to create a roux, cooking for 1-2 minutes until lightly browned.
  4. Build the Sauce Base:
    • Gradually whisk in the whole milk and half-and-half, ensuring a smooth mixture. Add Dijon mustard, garlic powder, salt, and pepper to taste. Continue whisking until the sauce thickens.
  5. Incorporate the Cheese:
    • Reduce the heat to low, then add the shredded cheese gradually, stirring until fully melted and the sauce is smooth.
  6. Combine Pasta and Sauce in the Slow Cooker:
    • Place the cooked macaroni in the slow cooker and pour the cheese sauce over it. Gently stir to ensure the pasta is well coated.
  7. Slow Cook to Perfection:
    • Cover the slow cooker and set it to low heat. Allow the macaroni and cheese to cook for 2-3 hours, stirring occasionally to prevent sticking.
  8. Serve and Garnish:
    • Once the macaroni is tender and the cheese sauce is creamy, it’s ready to be served. Optionally, garnish with your favorite toppings like bacon, sautéed onions, diced tomatoes, or fresh herbs.
