Ingredients:
- 1 lb (450 g) Elbow Macaroni or other short tube pasta
- 1 Tbsp Kosher Salt (for pasta water)
- 4 Tbsp (60 g) Unsalted Butter
- 1/4 cup (60 g) All-Purpose Flour
- 4 cups (950 ml) Whole Milk, warmed
- 2 1/2 cups (250 g) Sharp Cheddar Cheese, freshly grated
- 1 1/2 cups (200 g) Gruyère Cheese, freshly grated
- 1 tsp Dried Mustard Powder
- 1 tsp Fine Sea Salt
- 1/2 tsp Black Pepper, freshly ground
- 1/4 tsp Fresh Nutmeg, finely grated
- 1 cup (100 g) Panko Breadcrumbs
- 2 Tbsp (30 g) Unsalted Butter, melted (for topping)
- 1/2 tsp Smoked Paprika
Instructions:
- Preheat the oven to 375°F (190°C). Grease a 9x13 inch baking dish.
- Grate both the Cheddar and Gruyère cheeses and mix them together. Set aside. (Note: Always grate your own cheese for the smoothest sauce.)
- Cook the Pasta: Bring a large pot of salted water to a rolling boil. Add the macaroni and cook only until 2 minutes shy of al dente. Drain well and set aside.
- Melt the 4 Tbsp of butter in a heavy saucepan or Dutch oven over medium heat until foamy.
- Make the Roux: Whisk in the flour until a smooth paste forms. Continue stirring and cooking the roux for 1 to 2 minutes, ensuring it loses the raw flour smell.
- Add Milk: Slowly pour in the warm milk, whisking continuously to prevent lumps. The sauce should be smooth.
- Thicken Sauce: Bring the mixture to a gentle simmer, stirring frequently. Allow the sauce to thicken slightly, about 5–7 minutes, until it coats the back of a spoon.
- Remove the thickened béchamel from the burner. Whisk in the salt, pepper, mustard powder, and grated nutmeg.
- Create the Mornay: Gradually add the grated cheese mixture, one handful at a time, whisking until each addition is completely melted and smooth before adding the next. Do not allow the sauce to boil after the cheese is added.
- Combine the undercooked macaroni with the Mornay sauce and stir gently until every piece is evenly coated. Pour the mixture into the prepared baking dish.
- Prepare Topping: In a small bowl, combine the Panko breadcrumbs, melted butter, and smoked paprika. Toss until the breadcrumbs are fully coated. Sprinkle evenly over the pasta.
- Bake for 25–30 minutes, or until the sauce is bubbling around the edges and the topping is deeply golden brown and crisp.
- Rest: Let the dish rest for 10–15 minutes before serving. This allows the sauce to set up properly for an ultra-creamy texture.
