Serve as is or continue adding layers of butter, cheese, and noodles. Use extra cheese as necessary. Serve immediately, or place in a hot oven for several minutes and then serve. I find Cheddar cheese the tastiest, but feel free to try other varities . The dish is wonderful when prepared with undried freshly made noodles, but works with a dried purchased variety as well.
Egg noodles are probably the best to use when purchasing a commercial brand.
Keep in mind the difference in weight between dried and undried noodles.
