How to Make It
Heat oven to 400° F.
Place the fish in a small roasting pan. Add enough wine (about 3/4 cup) to reach halfway up the sides of the fish. Scatter the olives and lemon zest around the fish. Drizzle with the oil and season with 1/2 teaspoon salt, 1/4 teaspoon pepper, and the red pepper. Roast until the fish is cooked through and flakes easily with a fork, about 20 minutes.
Remove from oven and sprinkle with the parsley. Divide the fish among individual plates and spoon the olives and wine sauce over the top.
