Stuffed Zucchini Au Gratin


  • 1/2 lb (225 g) lean ground beef
  • 2 tablespoons (30 ml) olive oil
  • 1 onion, finely chopped
  • 4 oz (115 g) chopped white mushrooms
  • 2 cloves garlic, finely chopped
  • 1/2 cup (125 ml) chicken broth
  • 1/4 cup (60 ml) breadcrumbs
  • 4 to 6 large zucchini
  • 1 1/2 cups (375 ml) tomato sauce
  • 1 1/2 cups (375 ml) grated mozzarella
  • Salt and pepper


  1. In a skillet over high heat, fry the meat in the oil until well browned. Add the onion, mushrooms and garlic and cook until tender. Season with salt and pepper. Deglaze with the broth. Add the breadcrumbs and adjust the seasoning. Let cool.
  2. With the rack in the middle position, preheat the oven to 180°C (350°F).
  3. On a clean surface, trim the ends off the zucchini. Using an apple corer, hollow out each zucchini, creating a lengthwise tunnel about 2.5 cm (1 inch) in diameter, depending on the zucchini’s width.
  4. Using your fingers, stuff the zucchini. Lay them side-by-side in a 23 x 33-cm (9 x 13-inch) baking dish. Cover with sauce (see note) and top with cheese. Bake until the zucchini are tender, about 50 minutes.
  5. Serve whole, in sections or sliced.
