Spaghetti Squash (“Cucurbita pepo”)

Spaghetti Squash is something to consider introducing to your diet. It is relatively easy to find in the grocery stores in the winter as well as Farmer’s Markets in the late summer months. You can also grow it in your own garden! It is rich in vitamins and antioxidants, low in calorie and carbohydrates, high in fiber, and easy to prepare. Spaghetti Squash is different than typical squash varietals in that it can be shredded into strands resembling “spaghetti” and can be used as a gluten-free replacement to pasta, helping you achieve your carb reduction or weight loss goals.

What Is Spaghetti Squash


Spaghetti squash is a variety of winter squash, native to the Americas.  It is a large oval vegetable typically with a light yellow, thin skin. Similar to other winter squash, it has a netting of seeds at its center, which can be roasted and eaten separately.  Spaghetti Squash is unique, in that after cooking, its flesh can be shredded into long strands resembling spaghetti.  Its botanical name is Cucurbita pepo. 

How to Prepare

  • Rinse the exterior and cut in half length-wise

  • Remove seeds in the center with a large spoon, scrape out netting

  • Place on rimmed baking sheet or pan with cut-side down

  • Add about ¼ inch of water to pan

  • Bake in 375 degree oven for about 40 minutes or until the outer shell can be pressed down slightly with your finger

  • Remove from oven, flip each half to expose the flesh and let cool a few minutes

  • With a fork, scrape at the flesh, shredding it into spaghetti-like strands

How to grow Spaghetti Squash


Spaghetti squash can be grown by directly seeding in your garden.  Plant two weeks after the last spring frost, typically the end of May or early June in Minnesota. 


Chose a spot with full sun (at least 8 hours a day) and a loose, well-drained soil. Amend the soil with compost since the plants need nutrient-dense soil. Plant in hills, with 3 or 4 seeds per hill and 3 feet between each hill.  Provide 1 inch of water per week (1-5 gallons per plant) during the growing season.  Add water directly to the soil, avoiding the leaves. 


Spaghetti Squash takes approximately 100 days from planting to harvest – or by the end of August or September. Harvest before the first hard freeze. You can test the ripeness of the fruit by pressing your thumbnail into the rind. It should be hard to pierce.
