Ingredients:
- 1 lb Cavatappi or Large Elbow Macaroni
- 1 tbsp Sea Salt for pasta water
- 0.5 cup Unsalted Butter
- 0.5 cup All-Purpose Flour
- 4 cups Whole Milk, room temperature
- 1 tsp Mustard Powder
- 0.5 tsp Garlic Powder
- 0.5 tsp Smoked Paprika
- 0.25 tsp Nutmeg
- 0.5 tsp Fine Sea Salt
- 0.25 tsp Black Pepper
- 3 cups Sharp Cheddar, freshly grated
- 1.5 cups Gruyère or Fontina, freshly grated
- 0.5 cup Freshly grated Parmesan
- 1.5 cups Panko breadcrumbs
- 3 tbsp Unsalted Butter, melted
- 1 tbsp Fresh Parsley, finely chopped
Instructions:
- Bring a large pot of salted water to a rolling boil. Cook the pasta for exactly 2 minutes less than the package 'al dente' instructions. Drain the pasta but do NOT rinse.
- In a heavy-bottomed saucepan or Dutch oven, melt 0.5 cup of butter over medium heat. Whisk in the flour and cook for 2 minutes until fragrant and nutty but still pale in color.
- Gradually whisk in the room-temperature milk, one cup at a time, whisking constantly to ensure a smooth emulsion. Simmer until the sauce thickens enough to coat the back of a spoon.
- Remove from heat. Stir in the mustard powder, garlic powder, smoked paprika, nutmeg, salt, and pepper. Fold in the sharp cheddar and Gruyère until completely melted and velvety.
- Combine the cooked pasta with the cheese sauce, ensuring every noodle is coated. Transfer the mixture to a 9x13 inch baking dish.
- In a small bowl, mix the Panko breadcrumbs with 3 tbsp melted butter and chopped parsley. Sprinkle evenly over the pasta, followed by the grated Parmesan.
- Bake at 180°C (350°F) for 30 minutes, or until the sauce is bubbling at the edges and the crust has achieved a deep mahogany brown color.
