Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
Slice the zucchini, yellow squash, carrots, and red bell pepper into thin, even rounds or strips. Dice the onion and mince the garlic.
In a large skillet, heat the olive oil over medium heat. Add the onion and cook until translucent, about 3-4 minutes. Stir in the garlic and cook for an additional minute.
Add the carrots, zucchini, yellow squash, and red bell pepper to the skillet. Sauté the vegetables for 5-7 minutes, until slightly softened but not fully cooked.
Stir in the thyme, basil, salt, and black pepper. Adjust seasoning to taste. Remove from heat and set aside.
Transfer the vegetable mixture to the prepared casserole dish, spreading it out evenly.
In a small bowl, combine the panko breadcrumbs and grated Parmesan cheese. Melt the butter and drizzle it over the breadcrumb mixture, tossing to coat evenly.
Sprinkle the shredded mozzarella cheese over the vegetable layer, then top with the breadcrumb mixture.
Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and the vegetables are tender.
Allow the casserole to cool for 5 minutes before serving.
