Ingredients:
- 1 lb elbow macaroni
- 2 tbsp sea salt
- 4 tbsp unsalted butter
- 0.25 cup all-purpose flour
- 3 cups whole milk, cold
- 0.5 tsp ground nutmeg
- 1 tsp dry mustard powder
- 12 oz extra sharp cheddar cheese, hand-grated
- 4 oz Gruyère cheese, hand-grated
- 1 cup panko breadcrumbs
- 2 tbsp unsalted butter, melted
- 0.5 tsp smoked paprika
- 0.5 tsp salt
- 0.5 tsp black pepper
Instructions:
- Boil macaroni in water with 2 tbsp sea salt for 2 minutes less than the package directions for al dente. Drain and set aside.
- In a large saucepan or Dutch oven, melt 4 tbsp butter over medium heat. Whisk in flour and cook for 2 minutes until it smells like toasted shortbread.
- Slowly pour cold whole milk into the hot roux while whisking constantly. Continue cooking for 5-8 minutes until the sauce thickens enough to coat the back of a spoon. Whisk in nutmeg, and mustard powder.
- Remove from heat. Fold in the grated cheddar and Gruyère one handful at a time, stirring until the cheese is fully incorporated and glossy.
- Fold the cooked macaroni into the cheese sauce. Pour into a 9x13 inch baking dish.
- Mix panko breadcrumbs with 2 tbsp melted butter and smoked paprika. Sprinkle over the pasta and bake at 350°F (180°C) for 20 minutes until the edges are bubbling and the top is dark gold.
