Ingredients:

  • 2 lbs (900g) zucchini, sliced into 1/4-inch (6mm) thick rounds
  • 1 small yellow onion, chopped
  • 3 cloves garlic, minced
  • 1 lb (450g) ground beef (85% lean recommended)
  • 1 cup (115g) shredded mozzarella cheese
  • 1/2 cup (50g) grated Parmesan cheese
  • 2 tablespoons olive oil
  • 1 (14 oz / 400g) can diced tomatoes, drained
  • 1 cup (240ml) marinara sauce or pasta sauce
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup (50g) breadcrumbs (optional, for topping)

Instructions:

  1. Preheat the oven to 375°F (190°C). Salt zucchini slices, let sit to draw out moisture, then pat dry.
  2. Heat olive oil in a skillet. Sauté onion and garlic until softened.
  3. Add ground beef and cook, breaking it up, until browned. Drain excess fat if needed.
  4. Stir in diced tomatoes, marinara sauce, oregano, basil, salt, and pepper. Simmer briefly to blend flavors.
  5. Spread a layer of beef mixture in the baking dish. Layer zucchini, beef mixture, and mozzarella. Repeat layers, ending with mozzarella.
  6. Sprinkle breadcrumbs and Parmesan over the top for a lovely golden crust (optional).
  7. Cover with foil and bake for 25 minutes. Remove foil and bake until bubbly and golden.
  8. Let cool for a few minutes before serving.
