Preheat your oven to 190°C (375°F). In a large skillet over medium heat, add olive oil and sauté the diced onions until translucent, about 5 minutes. Add the minced garlic and cook for 1 additional minute until fragrant.
In a medium bowl, whisk together the heavy cream, beaten egg, smoked paprika, salt, pepper, and half of the parmesan cheese.
In a large mixing bowl, toss the dried zucchini rounds with the sautéed onion and garlic. Pour the cream mixture over the vegetables and stir gently to coat every slice.
Grease a 2-quart baking dish. Transfer the zucchini mixture into the dish, spreading it into an even layer. Top evenly with the shredded cheddar and mozzarella.
Mix the Panko breadcrumbs with the remaining parmesan and sprinkle over the top. Bake for 30 to 35 minutes until the zucchini is tender and the cheese crust is bubbling and golden brown.
The garlic butter sauce is the star — pick sides that soak it up or balance the richness.
