In a medium sized skillet melt butter over medium heat. As the butter melts, it will begin to foam. The color will slowly turn from a pale yellow to lightly golden and to finally, a toasted brown. Once the butter smells slightly nutty it’s ready for the butternut squash.
Reduce the heat to medium/low and add in the butternut squash stirring often. Cook until squash is soft enough to be pierced with a fork. Increase heat to medium high and add the fresh sage along with the gnocchi, cooking until the gnocchi begins to brown, about 4-5 minutes.
