Preparation

1. Preheat the oven to 350 degrees. Brush 1 tablespoon of olive oil over the bottom of a 12-by-3 1/2-inch round clay casserole dish. Layer 1/3 of the sweet potatoes in the dish, overlapping the slices slightly. Season with 3/4 teaspoon of salt and pepper. Scatter 1/3 of the onions over the sweet potatoes.
2. Repeat with the remaining sweet potatoes and onions, seasoning each layer of potatoes with 3/4 teaspoon of salt and pepper. Combine the wine and Sherry and pour over the top. Cover with aluminum foil and bake until the potatoes are tender, about 1 hour.
3. Meanwhile, in a bowl, combine the lemon juice, 1/4 cup of olive oil, 1/2 teaspoons of salt, pepper, pepper flakes and cayenne. Add the shrimp and toss to coat. Refrigerate until ready to use.
4. Scatter the prosciutto strips over the sweet-potato mixture. Top with the shrimp. Bake, uncovered, until the shrimp is just cooked through, about 16 minutes. Combine the bread crumbs with the parsley, 1/2 teaspoon of salt and pepper. Sprinkle the crumbs over the shrimp and place under the broiler until lightly browned, about 2 minutes. Serve immediately.
