Tips
Pierce the squash skin before cutting to prevent slipping and make halving easier.
Test doneness by checking if strands easily separate with a fork - they should be tender but not mushy.
Let the sauce thicken properly by whisking constantly and cooking until it coats the back of a spoon.
Good to Know
Refrigerate leftovers for up to 3 days in airtight container. Store sauce and squash separately to prevent sogginess.
