Preheat your oven to 350°F (175°C).

In a large skillet, combine the crab meat and softened cream cheese over medium heat, stirring until well-blended, about 5 minutes.

Cook the no yolk noodles according to package instructions, then drain and rinse under cold water.

In a large mixing bowl, combine the drained noodles with the crab mixture and fold in sliced green onions. Transfer the mixture into a greased casserole dish.

Sprinkle a layer of freshly grated Parmesan cheese over the top before baking.

Bake in the preheated oven for 25-30 minutes, until the cheese is bubbling and golden brown.

Let the casserole cool for about 10 minutes before serving.
