    Pour in the beef stock to deglaze the pan and finish cooking the onions until a thick jam consistency is reached.

  6. 6

    Boil the pasta in salted water until al dente.

  7. 7

    In a separate pan, prepare a roux with butter and flour, whisk in milk to create a béchamel sauce, then season with Dijon mustard and freshly ground black pepper.

  8. 8

    Stir the grated Gruyere cheese into the sauce until melted and smooth.

  9. 9

    Combine the cooked pasta with the cheese sauce and a portion of the caramelized onion mixture.

    Pulse the toasted baguette rounds in a blender to create a rough breadcrumb topping.

    Top the mac and cheese with the remaining caramelized onions and the baguette crumbs, then broil briefly to crisp the topping.
