1. Preheat your oven to 375°F (190°C). Grease a baking dish with a bit of olive oil to prevent sticking.
2. In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté until fragrant, about 1-2 minutes. Be careful not to burn the garlic!
3. Pour in the heavy cream and stir in the parmesan cheese, salt, pepper, and oregano. Let the mixture simmer for 3-4 minutes until the cheese is melted and the sauce thickens slightly.
4. Arrange the zucchini slices in the prepared baking dish, overlapping slightly. Pour the garlic parmesan sauce over the zucchini, ensuring every slice is well-coated.
5. Sprinkle the shredded mozzarella cheese evenly on top. If you like a bit of crunch, add a layer of breadcrumbs.
6. Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden brown. The zucchini should be tender when pierced with a fork.
7. Allow the bake to cool for a few minutes before serving. This lets the flavors meld together beautifully.

Remember, patience is key! Letting the dish rest before digging in allows the cheesy goodness to settle, enhancing every bite.
