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.
How to Grow Spaghetti squash
Plant it in rich, well-drained loam with plenty of compost, at a slightly acidic pH of 6–6.8.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. The details above are a starting point — your ground will teach you the rest.
Companion Planting & Soil
Spaghetti squash grows well alongside corn, bean, nasturtium, and marigold — but keep it clear of potato.

Uses
In the Kitchen
In the kitchen, spaghetti squash turns up in more than one form: baked and shredded as a low-carb pasta substitute; topped with marinara, pesto, or Alfredo sauce; mixed into casseroles and frittatas.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: low-calorie, fiber-rich vegetable; good source of B vitamins and manganese; beta-carotene supports immune and eye health. These are traditional uses, not medical advice.
Beyond the Garden
Spaghetti squash earns its keep past the plate, too: long-storing winter squash (several months at room temperature).
