verifiedReviewed by the GreenScout Team

Spaghetti squash is a winter squash variety that produces oblong, pale yellow fruits with mild, slightly sweet flesh that separates into thin strands resembling pasta when cooked. This warm-season vegetable requires substantial space and a long growing season (80–100 days) to reach maturity. It is a nutrient-dense, low-calorie alternative to traditional pasta and stores well for several months after harvest.
