In a large mixing bowl, combine the shredded turkey, cooked quinoa or rice, and steamed broccoli.
In another bowl, mix together the cream cheese, sour cream, heavy cream, garlic powder, onion powder, thyme, rosemary, paprika, salt, and pepper until smooth.
Pour the cheesy mixture over the turkey, quinoa, and broccoli. Stir well until all ingredients are fully combined and coated in the cheesy sauce.
Spread the mixture evenly into a greased 9x13 inch casserole dish.
In a small bowl, combine the breadcrumbs with olive oil, ensuring they're well-coated.
Evenly sprinkle the breadcrumb mixture over the top of the casserole, followed by the shredded cheddar cheese.
Place the casserole in the preheated oven and bake for 30-35 minutes, or until the top is golden and bubbly.
Remove from the oven and let it cool for a few minutes before garnishing with fresh chopped parsley. Serve hot and enjoy your cheesy herb goodness!
