Spaghetti squash

Overview

A unique winter squash whose cooked flesh separates into long, golden strands that resemble spaghetti noodles. This natural low-carb pasta substitute has made spaghetti squash one of the most popular winter squashes for health-conscious cooks. The mild, slightly sweet flesh acts as a blank canvas for sauces, pesto, and stir-fry toppings.
