Adjust oven rack to middle position and heat oven to 350 degrees F. Place rimmed, heavy-duty baking sheet or roasting pan on rack to heat.
Season each halibut fillet liberally with salt, pepper, and thyme.
Starting 1/2 inch in from the tip of each fillet, wrap with slices of pancetta, overlapping slightly. Wrap to within 1/2 inch of end of fillet.
Remove baking sheet from oven and place fish fillets, at least 2 inches apart, on the baking sheet.
Roast until pancetta has crisped and fish is opaque and beginning to flake, 10 to 15 minutes, uncovered, or until a meat thermometer registers an internal temperature of 140 degrees F. (halibut will be slightly opaque in thickest part). Remember the halibut continues to cook after it is removed from the heat source.
Serve immediately, sprinkled with parsley and accompanied by lemon wedge.
Makes 4 servings.
