Equipment

  • ovenproof skillet

Ingredients
  

  • 3 tablespoon extra-virgin olive oil
  • 4 large yellow onions, thinly sliced
  • 2 teaspoon kosher salt Diamond Crystal or 1¼ tsp. Morton
  • 1 teaspoon freshly ground black pepper
  • 6 cloves garlic, finely chopped
  • 4 teaspoon chopped thyme
  • ¾ cup dry white wine
  • 1 lb lumache (snail shells) or other medium shell pasta
  • 1 oz Parmesan, finely grated (about ½ cup)
  • 5 tablespoon unsalted butter
  • 1 tablespoon Dijon mustard
  • 2 teaspoon sugar
  • 2 teaspoon Worcestershire sauce
  • 8 oz Gruyère, coarsely grated (about 2 cups)
  • thinly sliced chives for serving; optional

Instructions
 

  • Heat 3 Tbsp. extra-virgin olive oil in a large high-sided ovenproof skillet over medium-high heat. Add 4 large yellow onions, a pinch of kosher salt, and a pinch of black pepper. Cook, stirring occasionally, until onions are deep mahogany color, 30–35 minutes.
  • Add 6 chopped garlic cloves and 4 tsp. chopped thyme. Cook until fragrant, about 1 minute. Add ¾ cup dry white wine and cook until reduced by half, about 3 minutes.
  • Add 5½ cups water and bring to a simmer. Add 1 lb. lumache and cook until almost all liquid has been absorbed and pasta is al dente, 10–14 minutes.
  • Remove from heat and stir in 1 oz. Parmesan, 5 Tbsp. unsalted butter, 1 Tbsp. Dijon mustard, 2 tsp. sugar, 2 tsp. Worcestershire sauce, remaining salt, and black pepper until cheese is melted.
  • Place a rack in the upper third of the oven and heat broiler. Scatter 8 oz. Gruyère over pasta and broil until melted and golden brown, 2–5 minutes.
  • Top with thinly sliced chives if using just before serving.
