Preheat your oven to 375°F (190°C) and lightly grease a baking dish with olive oil.
Slice the yellow squash, zucchini, and tomatoes into 1/4-inch thick rounds.
Mince the garlic, then combine it with 1 tablespoon of olive oil, fresh thyme leaves, salt, and black pepper in a small bowl.
In the greased baking dish, alternate and overlap slices of squash, zucchini, and tomatoes in rows or a circular pattern.
Drizzle the garlic, thyme, and olive oil mixture evenly over the vegetables.
Sprinkle half of the grated Parmesan cheese over the vegetables.
In a small bowl, mix the panko breadcrumbs with the remaining 1 tablespoon of olive oil and chopped fresh parsley.
Sprinkle the breadcrumb mixture evenly over the vegetables, followed by the remaining Parmesan cheese.
Bake the gratin in the preheated oven for 30-35 minutes, or until the top is golden brown, the cheese has melted, and the vegetables are tender when pierced with a fork.
Allow the gratin to cool for 5 minutes before serving. Serve warm as a main dish or side.
