  • plus 8 tsp. finely grated Parmesan cheese, divided
  • ground nutmeg

  • coarsely grated Swiss cheese (3 ounces)


1  Melt 3 Tbs. butter in large nonstick skillet over medium-high heat. Add mushrooms and shallots, and sauté 10 to 12 minutes, or until mushrooms are deep brown. Season generously with salt and pepper, if desired. Transfer to plate to cool.

2  Melt remaining 1 ½ Tbs. butter in heavy medium saucepan over medium-low heat. Add flour and stir until mixture bubbles. Whisk in milk. Boil 1 minute, or until thickened, whisking constantly. Remove from heat. Stir in 1⁄3  cup Parmesan and nutmeg. Season with salt and pepper, if desired. Set aside.
