Ingredients
- 1 spaghetti squash (2–4 lb)

FAQs
Can I make spaghetti squash ahead of time?
Yes. Roast, shred, and store in an airtight container in the fridge for up to 4 days. Reheat before serving.
Can I freeze spaghetti squash?
Yes, but the texture may soften after thawing. Freeze cooked strands in freezer-safe bags for up to 3 months.
Is spaghetti squash really like pasta?
It has a noodle-like texture, but is slightly sweet and more tender than traditional pasta. It’s best as a healthy substitute, not an exact replacement.
