Ingredients

  • 2 large baking potatoes, like russets, about 2 1/4 pounds
  • 5 ounces cardoons
  • 1 cup milk
  • 2 tablespoons chopped fresh thyme
  • 5 teaspoons minced garlic
  • 2 teaspoons red pepper flakes
  • Salt and freshly ground black pepper
  • 1 pound scamorza or mozzarella, sliced 1/2-inch thick
  • 1 1/2 red bell peppers, roasted, peeled, seeded and cut into pieces
  • 2 plum tomatoes, about 1 1/4 pounds, cut in half lengthwise
  • 1 large yellow onion, about 10 ounces, sliced 1/2-inch thick
  • 5 ounces green zucchini, sliced on the bias 1/2-inch thick
  • 1/2 cup extra-virgin olive oil
  • 1 cup grated pecorino

Method

  • Preheat oven to 350 degrees F.
  • Place the potatoes in a medium pot and cover with water by 1-inch.
  • Bring to a boil and cook until just tender, about 15 minutes.
  • Drain and when cool enough to handle, remove the skins.
  • Slice horizontally into 1/2-inch thick slices.
  • Peel stems of cardoons with a vegetable peeler.
  • Discard leafy tops.
  • Blanch peeled cardoons in a pot of boiling water with milk, until tender, about 3 minutes.
  • Remove and cool.
  • Cut into 1/2-inch pieces.
  • In a small bowl, combine thyme, garlic, red pepper flakes, salt, and pepper.
  • In a large oval casserole dish, alternately layer at an angle the potatoes, mozzarella, peppers, tomatoes, onions, and zucchini, seasoning between each layer with garlic, thyme, red pepper mixture, salt, and pepper.
  • Drizzle with the olive oil and bake until the vegetables are tender and beginning to turn golden brown, 35 to 40 minutes.
  • Sprinkle the cheese over the top and return to the oven until the cheese is melted, 5 to 8 minutes.
  • Remove from the oven and serve hot.
