Preheat the oven to 375Ā°F (190Ā°C). Bring a large pot of salted water to a boil. Cook the gluten free egg noodles according to package directions until just barely al dente ā they should still have a firm bite at the center, as they will continue cooking in the oven. Drain in a colander and set aside.
