2 Tbsp extra-virgin olive oil
2 Tbsp unsalted butter
2 pounds mixed wild mushrooms, stemmed if necessary and thickly sliced (10 cups)
2 shallots, minced
1/4 cup dry vermouth
3/4 cup chicken stock or low-sodium broth
1/2 cup heavy cream
1 tsp chopped thyme
salt and freshly ground pepper, to taste
2 pounds fresh or frozen prepared gnocchi
6 Tbsp freshly grated Parmesan cheese
Preheat the broiler.
In a large ovenproof skillet, heat the olive oil with the butter. Add the mushrooms and shallots and cook over high heat, stirring occasionally, until browned, 12 minutes. Add the vermouth and cook until evaporated. Add the stock, cream and thyme, season with salt and pepper; bring to a boil.
Meanwhile, in a large pot of boiling salted water, cook the gnocchi until they float to the surface, about 3 minutes. Drain well.
Add the gnocchi to the mushrooms and simmer, stirring, for 1 minute. Stir in 1/4 cup of the Parmesan and sprinkle the remaining 2 tablespoons of Parmesan on top. Broil the gnocchi 6 inches from the heat for 2 to 3 minutes, until golden and bubbling.
