  • 2 medium zucchini (thinly sliced lengthwise)
  • 1 tablespoon olive oil
  • pounds ground beef
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon oregano
  • 1 teaspoon parsley
  • ½ teaspoon salt
  • 2 cups tomato sauce
  • cups mozzarella cheese
  • ½ cup grated Parmesan
  • fresh herbs for garnish (optional)


  • Preheat the oven to 400°F. Line a large baking sheet with foil.
  • Place the sliced zucchini on the baking sheet and toss with oil.
  • Bake the zucchini for 10 minutes or until softened and some moisture has been released.
  • Meanwhile, add the beef to a skillet over medium heat. Add the garlic powder, onion powder, oregano, parsley, and salt.
  • Stir, breaking the beef into smaller pieces in the pan, and cook until browned.
  • Drain the excess fat from the beef, then add the tomato sauce to the skillet and stir.
  • In an 8×8 baking dish, start by adding a small layer of ground beef mixture to the bottom. Next, layer on the zucchini slices.
  • Add more ground beef mixture, then mozzarella cheese.
  • Repeat for a total of 3 layers, then top with Parmesan cheese.
  • Bake, uncovered, for 30-35 minutes or until the cheese is brown and bubbly.
