# How-To Steps:
01 - Preheat oven to 390°F. Grease a medium baking dish with butter or cooking spray.
02 - Bring a large pot of salted water to a rolling boil. Add macaroni and cook according to package instructions until just al dente. Drain thoroughly and set aside.
03 - In a large saucepan, melt 2 tablespoons butter over medium heat. Add flour and whisk continuously for 1 to 2 minutes until the mixture reaches a pale golden color.
04 - Gradually pour in milk while whisking constantly to prevent lumps. Bring to a gentle simmer and cook for 4 to 5 minutes until the sauce thickens noticeably.
05 - Remove from heat and add Gruyère, cheddar, Fontina, and Parmesan cheeses. Stir until completely melted and smooth. Season with Dijon mustard, black pepper, salt, and nutmeg.
06 - Add the cooked macaroni to the cheese sauce and stir thoroughly until every piece is evenly coated.
07 - Pour the macaroni and cheese mixture into the prepared baking dish, spreading evenly.
08 - In a small bowl, combine panko breadcrumbs, 2 tablespoons grated Parmesan, and melted butter. Mix until the breadcrumbs are evenly moistened.
09 - Sprinkle the breadcrumb mixture evenly over the pasta. Bake for 15 to 20 minutes until the top is golden brown and the edges are bubbling.
10 - Remove from oven and let rest for 5 minutes. Drizzle with black truffle oil and scatter shaved truffle over the surface. Garnish with fresh chives if desired, then serve.
