Ingredients

  1. 1 lb ground beef
  2. 1 medium onion, chopped
  3. 3 cloves garlic, minced
  4. 34 medium zucchini, sliced into rounds or half-moons
  5. 1 can (14.5 oz) diced tomatoes, drained
  6. 1 can (8 oz) tomato sauce
  7. 1 tbsp Italian seasoning
  8. Salt and pepper, to taste
  9. 1 cup shredded cheddar cheese
  10. 1 cup shredded mozzarella cheese
  11. 12 tbsp olive oil or butter

Instructions

Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

  1. In a large skillet over medium-high heat, cook ground beef until browned, breaking it apart with a spoon. Drain excess fat if needed.
  2. Add onion and garlic to the beef and sauté until softened.
  3. Stir in diced tomatoes, tomato sauce, Italian seasoning, salt, and pepper. Simmer for 5 minutes.
  4. In a separate skillet, sauté zucchini slices in olive oil or butter for 3–4 minutes until slightly tender.
  5. Layer half of the zucchini slices in the baking dish. Spread half of the beef mixture over the zucchini, then sprinkle with half of the cheddar and mozzarella cheese.
  6. Repeat with remaining zucchini, beef mixture, and cheese.
  7. Cover with foil and bake for 20 minutes. Remove foil and bake for an additional 10–15 minutes, until cheese is melted and bubbly.
  8. Let stand for 5 minutes before serving.

Notes

  1. For a lighter version, use ground turkey or chicken.
  2. Add sliced mushrooms or bell peppers for more vegetables.
  3. Swap Italian seasoning for taco seasoning and use pepper jack cheese for a Tex-Mex twist.
  4. Salt zucchini and pat dry before cooking to reduce moisture.
  5. Can be assembled a day in advance and refrigerated until baking.
