  • Stir over medium heat, bring the mixture to a boil, and let it simmer for about 2 minutes.

  • Reduce heat to low and add 3 cups of cheddar cheese and 1 cup of mozzarella cheese, freshly grated or pre-shredded. Stir to combine, until the cheese is fully melted.
  • Remove the pan from heat and add the cooked elbows macaroni. Stir to combine.
  • Transfer the mixture to the prepared casserole dish.
