Cut 8 pieces of parchment (or aluminum foil) into squares large enough to cover each fish fillet with a two-inch border all around. Lightly brush 4 squares with olive oil. Preheat the oven to 350°F.

Put halibut in the center and drizzle with Champagne. Add 2 sprigs of thyme, 2 lemon slices, 2 parsley sprigs and ½ tsp fennel seeds on each piece of fish. Season to taste.

Use the remaining parchment squares as top sheets, fold the edges up to form packets. Simply double-folding each of the four sides is enough to seal each filet. Put on baking sheet and bake for 10-15 minutes in preheated oven.

Serve by setting each packet on a plate. Let your guests open the packet and spoon juices over the fish. Voilà—Drama as well as flavor!
