Spaghetti squash is an oblong winter squash with smooth skin ranging in color from cream to orange with a seed-filled cavity at its center. It is harvested in the early fall and available through the winter. Unlike other winter squash, such as the sweet and nutty butternut, spaghetti squash has a mild flavor, which makes it a great backdrop for a variety of flavors.

After cooking, the flesh of a spaghetti squash can be separated into delicate strands, comparable to angel hair pasta. The noodle-like texture and subtle flavor of spaghetti squash makes it a versatile vegetable, which goes well with a variety of flavored sauces – including marinara, pesto, curry and more.

A bonus of making spaghetti squash for dinner is that you can get a snack for the next day, if you roast the seeds the same way you would pumpkin seeds. Try for yourself by following our super-easy instructions on how to roast pumpkin seeds.

The health benefits of spaghetti squash are great. Spaghetti squash contains folic acid, potassium, vitamin A and other nutrients. For maximum health benefits, choose a squash with color closer to the orange end of the spectrum. More color means more beta-carotene, which your body converts to vitamin A contributing the healthy skin, vision and more.

When shopping for spaghetti squash, look for thick, hard skin and no soft spots. Choose a squash that is heavy for its size with a dull-colored rind.

Just one more benefit of spaghetti squash is that you can forget about it for up to 2 months, if stored correctly. Like potatoes, spaghetti squash should be stored whole in a cool (45-60°F) dry, dark place with good ventilation.

How to Cook Spaghetti Squash?

It’s easy to cook spaghetti squash in the oven in 30 minutes. In fact, the hardest part about making spaghetti squash for dinner is most certainly cutting it open, so without further ado, here’s how to bake spaghetti squash.

What You Need:

  • paring knife
  • 8” chef’s knife
  • cutting board
  • large serving spoon
  • 13x9-inch baking dish
  • fork
  • kitchen towel


  • 2 lb. spaghetti squash
  • water

1. Preheat your oven to 350°F.


2. Place the kitchen towel on the cutting board and lay the squash on top so the towel is like a cushion between the board and the squash. The towel is there to help keep the squash from rolling across the smooth surface of the cutting board. Using the paring knife, begin scoring the skin of the squash starting just below the stem. When you get to the bottom of the squash, turn it over and continue the score up the other side. You do not need to cut all the way through the skin, but taking this step will make it easier to cut the squash in half.


3. Next, use your chef’s knife to cut all the squash in half. Following the line of your score, and again starting below the stem, it should be relatively easy to cut through the squash. If you start below the stem, you should be able to split the squash in half, and then set your knife aside and pull the two halves apart to break the sturdy stem.


4. Once you have the squash cut in two, use your large spoon to scrape out the seeds. Scrape away until there is no slime or seed left inside the cavity. Remember, you can roast the seeds for a snack. The directions are the same as for roasting pumpkin seeds.


5. When both cavities are clean, place squash halves cut side down in the 13x9-inch baking dish, and pour in enough water to cover the bottom. If you want to speed up the process a bit, cover the pan with tinfoil before putting in the oven. The tinfoil helps trap the heat, steaming the squash more quickly. Check the squash after 30 minutes. It should be fork tender. Depending on the size of the squash, it may take up to 45 minutes to cook.


6. After removing the squash from the oven, let cool. Then, take a fork and comb along the flesh, starting inside the cavity to separate the fibers. They should unfurl easily but use a gentle hand, if you are looking for noodle-like tendrils.


7. Now that you have a bowl of spaghetti squash noodles, there are a number of different dishes you can make.


Different Methods for Making Spaghetti Squash

While it is easy to bake spaghetti squash in the oven and that method yields great results, it is not the only way to cook spaghetti squash. Depending on the recipe you are making, one of the methods listed below might work even better.
