Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish with butter or non-stick spray.
Peel the potatoes and slice them into thin rounds, about 1/8-inch thick. Slice the zucchini into similar thin rounds.
Grate the sharp cheddar cheese and set it aside. Mince the garlic cloves finely.
In a saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1-2 minutes until fragrant. Stir in the heavy cream, fresh thyme, salt, and black pepper. Heat the mixture until just warm, then remove from the heat.
Layer one-third of the potato slices in the bottom of the prepared casserole dish, slightly overlapping them. Follow with a layer of half the zucchini slices.
Sprinkle one-third of the cheddar cheese over the zucchini, then pour one-third of the cream mixture on top. Repeat this process, layering potatoes, zucchini, cheese, and cream, ending with a layer of potatoes and the remaining cream mixture.
Sprinkle the remaining cheddar cheese and all the Parmesan cheese evenly over the top layer of potatoes.
In a small bowl, toss the breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the cheese.
Cover the casserole with aluminum foil and bake in the preheated oven for 30 minutes. Then, remove the foil and bake for an additional 20 minutes, or until the top is golden and bubbly and the potatoes are tender when pierced with a fork.
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. Garnish with fresh thyme if desired.
