Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set it aside.
Slice the yellow squash, zucchini, and butternut squash into thin, even rounds. Finely dice the onion.
In a large skillet, heat the olive oil over medium heat. Add the diced onion and cook until softened, about 3-4 minutes.
Add the sliced squash to the skillet, season with half of the salt, pepper, and garlic powder, and sauté for 5-7 minutes until just tender. Remove from heat and set aside.
In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute until bubbly and golden.
Gradually whisk in the milk and heavy cream, stirring constantly to avoid lumps. Cook for 2-3 minutes until thickened.
Stir in the shredded cheddar cheese and grated Parmesan cheese, reserving a handful of cheddar for topping. Mix until smooth and creamy.
Season the cheese sauce with the remaining salt, pepper, and garlic powder. Adjust seasoning to taste.
In a large mixing bowl, combine the sautéed squash and onions with the cheese sauce, ensuring all the vegetables are well coated. Transfer the mixture to the prepared baking dish.
In a small bowl, combine the breadcrumbs with the reserved cheddar cheese and chopped parsley. Sprinkle the mixture evenly over the casserole.
Bake in the preheated oven for 25-30 minutes, or until the top is golden and the casserole is bubbling around the edges.
Allow the casserole to cool for 5-10 minutes before serving. Garnish with additional parsley if desired.
