Creating Ground Beef Zucchini Boats is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).

2. Prepare Zucchini: Cut the zucchinis in half lengthwise. Scoop out the seeds to create a hollow boat shape.

3. Season Zucchini: Place the zucchini halves cut side up on a baking sheet. Drizzle with olive oil and sprinkle with salt and pepper.

4. Cook Ground Beef: In a skillet over medium heat, add the diced onion and garlic. Sauté until softened, about 3-4 minutes.

5. Add Beef: Add the ground beef to the skillet. Cook until browned, breaking it apart with a spoon.

6. Mix in Tomatoes and Spices: Stir in the diced tomatoes, Italian seasoning, salt, and pepper. Cook for an additional 5 minutes until heated through.

7. Fill Zucchini: Spoon the beef mixture into the hollowed-out zucchinis, packing it in gently.

8. Top with Cheese: Sprinkle the shredded mozzarella and Parmesan cheese on top of each filled zucchini half.

9. Bake: Place the zucchini boats in the preheated oven and bake for 25-30 minutes, or until the zucchini is tender and the cheese is melted and bubbly.

10. Serve: Remove from the oven and let cool slightly before serving.
