1. Heat oven to 400 degrees. Toss together potatoes, 2 tablespoons oil, capers, 3/4 teaspoon thyme, 1/2 teaspoon rosemary, and 1/2 teaspoon salt in a bowl until evenly coated.

2. Heat 2 tablespoons oil in a large skillet over medium heat until shimmering. Add onions, sugar, and 1/2 teaspoon salt and cook, stirring often, until onions are golden brown, about 20 minutes. Add garlic and remaining thyme and rosemary and cook for 1 minute. Whisk in vermouth, scraping up any brown bits, and cook until liquid has evaporated, 1 to 2 minutes. Remove from heat and season with salt and pepper to taste.

3. Arrange 1/3 of the potato mixture evenly in the bottom of a greased 9x13" baking dish. Sprinkle roasted red peppers over potatoes and top with another 1/3 of the potato mixture. Spread onion mixture evenly over potatoes and top with the remaining potato mixture and any accumulated liquid; reserve bowl.

4. Toss zucchini with 1 tablespoon oil and 1/2 teaspoon salt in reserved bowl and shingle over potatoes. Cover tightly with aluminum foil and bake for 1 hour.

5. Meanwhile, toss Parmesan, panko, lemon zest, and remaining 3 tablespoons oil together in a bowl. Remove foil, sprinkle panko mixture evenly over gratin, and continue to bake until golden brown, 25 to 30 minutes. Let cool 15 minutes. Sprinkle with parsley and serve with lemons.
