Preparation

Step 1

In a large (12-inch) skillet, warm the butter over medium heat. Add the onions and cook, stirring occasionally, until they are soft and translucent.

Stir in the sugar and a pinch of salt, and reduce the heat to low. Cook the onions slowly for about 1 hour, stirring occasionally. Patience is key! When they're done, they should be dark, caramelized, and borderline jammy.

Stir in the Madeira, cook for a few more minutes, and then add the cooked pasta to the pan. Shower on a generous dusting of Parmesan, and using two large spoons, toss the pasta well with the sauce.

Serve with additional grated Parmesan, and flaky salt if necessary.
