Is spaghetti squash healthy?

Yes! Spaghetti squash is healthy. According to Healthline, it's particularly healthy because it's low in calories while being high in nutrients. It brims with fiber, manganese, vitamin C, vitamin B6, and more.

This impressive profile makes it good for you on its own or as a substitute for pasta, as we have here in this Basil Pesto Spaghetti Squash Pasta Recipe.

How do you cut a spaghetti squash?

To cut your spaghetti squash, first, make sure you have a very sharp and long knife. A chef's knife or de-boning knife are both perfect for this.

Then, rest your squash on a cutting board and cut the top stem off, slicing off about a ½ inch round of the squash off underneath the stem.

Next, cut the squash open lengthwise to expose the squash seeds. Scoop the seeds out and throw away.

Turn the squash over so the inside of each of the squashes faces downwards. Then, cutting perpendicular to the lengthwise cut, slice the squash into 1-1.25 inch pieces. They should then look like half-moons or the shape of rainbows.

Continue cutting the rest of the squash into 1-1.25 inch pieces and you have cut up your squash!

How do you cook spaghetti squash?

There are a few ways to cook a spaghetti squash, depending on how you want to serve it. You can rub it with olive oil, garlic, and salt, and roast it at a higher heat to have a caramelized and golden brown squash, or you can steam in it in the oven at a moderately-high heat to create a more tender and juicy pasta textured squash.

To steam it in the oven, cut your squash in half lengthwise, de-seed it, and then crosswise into 1.25 inch thick half-moons (see the picture below). Then add the squash to an 8 x 13" baking pan, add about an inch of water, and cover the pan tightly with aluminum foil.

Next, add the squash to an oven preheated to 400 degrees Fahrenheit and roast for 40-45 minutes, or until the squash flakes easily when scraped with a fork. Now you have tender & nutty spaghetti squash pasta to enjoy!

Basil Pesto Spaghetti Squash Pasta Recipe

Chelsea Plummer | Mae's Menu
A rich and satisfying way to enjoy pesto that is big on veggies as well as flavor!
This pesto recipe makes about twice as much as you need for this amount of squash. Either halve the recipe or freeze the remaining pesto (see the directions in the recipe notes) for an easy way to enjoy it again later.
Prep Time 10 minutes
Cook Time 45 minutes
Total Time 55 minutes
Course Main Dish
Cuisine Italian
Servings 4 servings
Calories 229 kcal

Ingredients
  

  • 1 medium-size spaghetti squash cut in half lengthwise & de-seeded
  • 2 cups packed basil
  • ½ cup walnuts halves
  • ½ cup olive oil
  • cup grated parmesan cheese
  • ¾ teaspoon salt
  • 3 medium size garlic cloves

Instructions
 

  • Preheat the oven to 400 degrees.
  • Slice the halves of the squash crosswise into 1.25-inch pieces, forming half-moon or rainbow shaped pieces.
  • Add the squash pieces to an 8x13 baking pan.
  • Add an inch of water to the pan and cover the pan tightly with foil so no air can escape.
  • Add the pan to the oven and bake for 40-45 minutes, or until the spaghetti squash is tender and flakes easily when scraped with a fork.
  • While the squash bakes: add the rest of the ingredients -- the basil through the garlic cloves -- to the bowl of a food processor or blender and run on high speed for 30-45 seconds, or until the walnuts and basil are broken down and the pesto is the texture of a thick sauce.
  • Remove the pan from the oven and place it on a wire cooling rack. Remove the foil from the pan and let the squash cool for 5-10 minutes, or until the squash isn't steaming anymore.
  • Using a large spoon and fork, move the squash to a cutting board and scrape the squash out of the shell. I like to hold the shell down with the spoon in one hand while scraping the squash out with my right hand.
  • Dish the loose spaghetti squash "pasta" into bowls, top with 1.5-2 tablespoons pesto and serve hot!

Notes

1. To freeze leftover pesto, simply add it to a quart-size freezer bag and freeze for up to 3 months. You can defrost it later by soaking in warm water for 20-30 minutes.
2. Leftover spaghetti squash pasta will keep covered in the fridge for 4-5 days.
