In a large skillet, heat the olive oil over medium heat. Add the cauliflower and broccoli florets, sautéing for about 5-7 minutes until they are tender but still crisp.
In a mixing bowl, combine the heavy cream, softened cream cheese, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix until well combined.
In a greased 9x13 inch baking dish, layer the sautéed vegetables on the bottom.
Spread the shredded chicken evenly over the vegetables.
Pour the creamy mixture over the chicken and vegetables, ensuring everything is well coated.
Sprinkle shredded cheddar cheese evenly on top of the casserole, followed by the grated Parmesan cheese.
Bake in the preheated oven for about 25-30 minutes, or until the cheese is bubbly and golden brown.
Remove from the oven and let it cool for a few minutes. Garnish with chopped parsley before serving.
