Ingredients

• 1 pound elbow macaroni pasta
• 4 tablespoon unsalted butter
• 3 tablespoon all-purpose flour
• 3 cup whole milk
• 3 cup sharp cheddar cheese, shredded
• 1 cup gruyère cheese, shredded
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon cayenne pepper
• 0.5 teaspoon dijon mustard
• 1 cup panko breadcrumbs
• 2 tablespoon melted butter
• 2 tablespoon fresh parsley, chopped

Steps

1. Preheat your oven to 350°F (175°C).
2. Fill a large pot with 6 quarts of water and bring it to a boil over high heat.
3. Add the elbow macaroni pasta to the boiling water and cook for 2 minutes less than package directions (usually about 6 minutes for al dente). The pasta will finish cooking in the oven.
4. Drain the pasta in a colander and set aside. Do not rinse.
5. In a medium saucepan, melt 4 tablespoons of butter over medium heat.
6. Whisk in the flour until smooth, creating a light roux, and cook for 1 minute while stirring constantly.
7. Slowly pour in the milk while whisking continuously to avoid lumps.
8. Continue cooking and stirring until the sauce thickens, about 3 to 4 minutes.
9. Remove from heat and stir in the sharp cheddar and gruyère cheeses until completely melted and smooth.
10. Season the cheese sauce with salt, black pepper, cayenne pepper, and dijon mustard, stirring well to combine.
11. Pour the cooked pasta into a 9x13 baking pan.
12. Pour the cheese sauce over the pasta and gently fold together until all pasta is evenly coated.
13. In a small bowl, combine the panko breadcrumbs, melted butter, and chopped fresh parsley.
14. Sprinkle the breadcrumb mixture evenly over the top of the pasta.
15. Bake in the preheated oven for 25 to 30 minutes, until the top is golden brown and the sauce is bubbling around the edges.
16. Remove from the oven and let rest for 5 minutes before serving.
