Gruy?re, a rich and nutty Swiss cheese, makes this mushroom bake as sinfully decadent as it is elegant. Chestnuts add a festive note and can be found in the produce section of most grocery stores.

Gruyère Crumb Topping:


In large skillet, melt 2 tbsp of the butter over medium heat; cook leeks, garlic and half each of the salt and pepper, stirring, until leeks are softened, about 6 minutes.Remove to bowl; set aside.

In same skillet, melt remaining butter over medium heat; cook cremini mushrooms, oyster mushrooms and remaining salt and pepper, stirring occasionally, until mushrooms are just tender and have released their juices, 5 to 8 minutes. Sprinkle with flour; cook, stirring, until light golden, about 2 minutes. Stir in leek mixture.

Whisk in broth, cream and mustard until smooth. Cook, whisking, until thickened, 3 to 5 minutes. Stir in chestnuts (if using), parsley, thyme and lemon juice. Spoon into 8-cup (2 L) casserole dish. (Make-ahead: Let cool to room temperature; cover and refrigerate for up to 24 hours. To reheat, cover with foil and bake in 375 F/190 C oven until hot and bubbly, about 45 minutes; uncover and continue with recipe.)
