What’s the Best Recipe for a Schupfnudel Casserole?

I’m looking to make a hearty Schupfnudel Auflauf (Schupfnudel casserole) and need some recipe ideas.

What’s the best way to layer and bake the Schupfnudeln to get a deliciously creamy and flavorful dish? Are there specific ingredients or seasonings that really enhance the taste? Any tips on preparation and baking times would be helpful!
