Ingredients

Scale

2 medium zucchinis (about 2 lbs), sliced
• 1 tbsp olive oil
• 1 small onion, diced
• 2 garlic cloves, minced
• 1 lb lean ground beef
• 2 tsp Italian seasoning
• ½ tsp kosher salt
• ½ tsp black pepper
• 1 (28 oz) can diced tomatoes, drained

Instructions

Preheat oven to 375°F (190°C).

In a large skillet, heat olive oil over medium heat. Sauté onion and garlic until soft, about 3 minutes.

Add ground beef, Italian seasoning, salt, and pepper. Cook until beef is browned.

Stir in drained tomatoes and cook for 2–3 minutes to blend flavors.

In a greased 9×13-inch baking dish, layer half the zucchini slices.

Spread half the beef mixture over the zucchini, then sprinkle with 1 cup mozzarella.

Repeat with remaining zucchini, beef, and top with the rest of the cheese.

Cover with foil and bake for 20 minutes. Remove foil and bake another 10–15 minutes until bubbly and golden.

Let rest 5–10 minutes before serving.
