  • 2 cups shredded mozzarella cheese Adds delightful stringiness.

Liquids

  • ½ cup sour cream Greek yogurt can also substitute for an extra protein boost.

  • ¼ cup grated Parmesan For extra flavor.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • Cook the elbow macaroni according to package instructions, but slightly undercook it by 1-2 minutes for that perfect al dente bite.
  • In a large saucepan, melt the butter over medium heat. Stir in the flour to form a roux, cooking for about 2 minutes until bubbly and slightly golden.
  • Gradually whisk in the whole milk, allowing it to thicken into a creamy sauce. Add salt, pepper, and Dijon mustard.
  • Remove from heat and stir in the cheddar and mozzarella until fully melted and creamy.
  • In a large mixing bowl, combine the macaroni with the cheese sauce and sour cream, ensuring every piece is luxuriously coated.
  • Pour the mixture into a greased 9x13 inch baking dish. If using breadcrumbs, sprinkle them over the top along with the Parmesan.

Baking

  • Bake for 30-35 minutes or until bubbly and golden brown on top.
  • Let it cool for a few minutes, then serve.

Notes

Leftovers can be stored in an airtight container in the fridge for up to 3 days, or frozen in single-serving containers. Reheat at 350°F (175°C) or microwave with a splash of milk.
