Ingredients

Makes 4 servings

　　1 (3/4-pound) piece Gruyère, rind discarded

　　4 slices Canadian bacon

　　1 veal tenderloin (1 1/4 pound), trimmed and cut crosswise into 4 equal pieces (tournedos)

　　1 tablespoon unsalted butter

　　1/2 cup crème fraîche

　　

Step 1

Preheat oven to 450°F.

　　

Step 2

Using a cheese planer or a sharp knife, cut 4 thin slices (4- by 2-inch) from Gruyère.

　　

Step 3

Cook bacon in a ovenproof 10-inch heavy skillet over moderately high heat, turning once, until lightly browned, about 2 minutes total, and transfer to a plate. (Do not clean skillet.)

　　

Step 4

Pat veal dry and season with salt and pepper. Heat butter in skillet over moderately high heat until foam subsides, then sauté tournedos until browned, about 4 minutes total. (Veal will be only partially cooked.)

　　

Step 5

Remove skillet from heat and put a slice of bacon, then cheese and crème fraîche, on each tournedos. Roast in middle of oven, uncovered, until cheese begins to melt, 8 to 10 minutes. (Veal should be slightly pink inside.)

　　

Step 6

Transfer tournedos to plates. Whisk pan juices until blended, season with salt and pepper, then divide among plates.
