Ingredients

  • 3 pounds plum tomatoes (about 12 to 14), halved
  • Salt for seasoning, plus 1 teaspoon
  • Freshly ground black pepper for seasoning, plus 1/4 teaspoon
  • 3 medium eggplants (about 3 pounds), cut into 1/2-inch slices
  • 3 tablespoons olive oil
  • 3 large red onions (about 3 pounds), halved and sliced
  • 3 large yellow onions (about 3 pounds), halved and sliced
  • 6 cloves garlic, chopped
  • 1/2 cup white wine
  • 2 cups homemade or low-sodium chicken stock
  • 1 1/4 teaspoons chopped fresh rosemary
  • 1 1/4 teaspoons chopped fresh thyme

Method

  • Preheat oven to 300 degrees.
  • Season the cut sides of the tomatoes lightly with salt and pepper and place cut sides down on a lightly oiled baking sheet.
  • Bake until the tomatoes are very lightly browned and collapsed, about 3 hours.
  • Set aside.
  • Raise the oven temperature to 450 degrees.
  • Sprinkle the eggplant slices lightly with salt and transfer them to a large colander to drain for 30 minutes.
  • Wipe the slices dry with paper towels and place them in a single layer on one or more lightly oiled baking sheets.
  • Roast the eggplant slices, turning once, until they are soft and lightly browned, about 20 minutes.
  • Set aside.
  • Meanwhile, in a large, heavy-bottomed kettle, heat the 3 tablespoons of olive oil over medium heat and add the red and yellow onions and garlic.
  • Cook, stirring frequently, until the onions are very soft and lightly caramelized, about 25 minutes.
  • (Lower the heat if the bottom of the pan begins to scorch.)
  • Add the wine, stock, herbs and 1 teaspoon salt and 1/4 teaspoon pepper.
  • Raise the heat to high and continue to cook until the mixture thickens slightly, about 5 minutes.
  • Lower the oven to 400 degrees.
  • Spread a thin layer of the onion mixture in the bottom of a 13-by-9-inch baking pan.
  • Top with half the eggplant slices, half the tomatoes and half of the remaining onions.
  • Top with the remaining eggplant slices, tomatoes and onions.
  • Bake until bubbly and lightly browned, about 35 to 40 minutes.
  • Let stand for 10 minutes before serving.
