I always thought I hated squash. I had bad memories of it as a kid, being stringy and having no flavor. Which is probably a pretty common feeling about most veggies when you’re a child, right?

Luckily times have changed, and I’ve been willing to try a lot more vegetables as I’ve gotten older – spaghetti squash being one of them.

A foray into Whole30 a few years ago introduced me to this love, and I actually like it more than pasta! In fact, this spaghetti squash recipe is a replacement for pasta.

If you’re trying to get healthy – or just want to try something new and delicious – this dish is for you.

You can make this spaghetti squash recipe in an Instant Pot in a matter of minutes. Once you try it, you’re never going to go back – I promise!

How to Cook Spaghetti Squash in the Pressure Cooker

  • One medium spaghetti squash
  • 1 cup water
  • 1/4 cup parmesan cheese
  • 1/2 tablespoon extra virgin olive oil
  • 1 teaspoon parsley
  • 1/4 lb hamburger (or ground turkey, or ground veggie sausage)
  • 1 cup tomato sauce (pre-seasoned is good)
  • Salt/pepper to taste

Tools

Start by cutting your squash – using a sharp blade as opposed to a saw-type. Sawing a squash doesn’t work as well as piercing and cutting with a paring knife . . . trust me!

You can cut it either lengthwise or through the middle. Depends on how long you want the strands because either way works.
