👨‍🍳 How to Make Stuffed Zucchini with Ground Beef

1️⃣ Prepare the Zucchini

Preheat oven to 375°F (190°C). Wash zucchini, slice them lengthwise, and scoop out the center flesh using a spoon to create “boats.” Lightly season with salt and set aside.

2️⃣ Cook the Filling

Heat olive oil in a pan over medium heat. Sauté onion and garlic until fragrant. Add ground beef and cook until browned. Stir in crushed tomatoes, chopped zucchini flesh, salt, pepper, and optional spices. Simmer for 5–10 minutes until slightly thickened.

3️⃣ Stuff the Zucchini

Place zucchini halves in a baking dish. Fill each boat generously with the meat mixture.

4️⃣ Add Cheese & Bake

Sprinkle grated cheese over the top. Bake for 20–25 minutes, or until zucchini is tender and cheese is golden and bubbly.

5️⃣ Serve

Garnish with fresh parsley and serve warm.
