Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish and set aside.
Wash the zucchinis thoroughly, remove the ends, and slice them into 1/4-inch rounds. Arrange the slices in overlapping rows in the prepared baking dish.
In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute, until fragrant.
Whisk in the flour, stirring continuously, and cook for 1-2 minutes to eliminate the raw flour taste.
Gradually add the milk and heavy cream, whisking constantly to create a smooth mixture. Bring the sauce to a gentle simmer and cook for 3-4 minutes, until slightly thickened.
Stir in the salt, black pepper, and parmesan cheese, allowing the cheese to melt completely into the sauce. Remove from heat.
Pour the cheese sauce evenly over the zucchini slices, ensuring every piece is coated.
In a small bowl, toss the panko breadcrumbs with olive oil until evenly coated. Sprinkle the shredded cheddar cheese on top of the zucchini, followed by the breadcrumb mixture.
Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and the zucchini is tender when pierced with a fork.
Remove from the oven and let rest for 5 minutes before serving. Garnish with fresh parsley if desired.
