Cooked instant pot spaghetti squash

My childhood memories of squash were less than stellar—picture a stringy, flavorless mess that seemed more like a dinner table punishment than a meal.

Sounds familiar? I bet it does for anyone who ever turned up their nose at veggies as a kid.

But, as with most things in life, time and taste buds evolve. And so has my relationship with vegetables, particularly one game-changing gourd: the spaghetti squash.

Who knew this unassuming veggie could be a culinary rockstar? And something that I would love?

My journey to embracing spaghetti squash wasn’t overnight. It all started with a Whole30 adventure a few years back.

If you haven’t heard of Whole30, it’s a month-long food voyage where you strip back your diet to the basics, ditching sugar, alcohol, grains, and more to reset your eating habits.

It was during this time that spaghetti squash waltzed into my life, not just as a veggie, but as a surprising replacement for pasta. Yes, you heard that right – a vegetable dethroning the beloved pasta!

But can a squash really replace pasta? I was skeptical too, but hear me out.

This isn’t about an exact replica of pasta’s taste and texture but discovering a deliciously unique alternative that’s healthier and just as satisfying.

Enter the hero of our story: the Instant Pot. The Instant Pot makes cooking spaghetti squash not only effortless but fun.

You’re not just boiling a vegetable; you’re creating a culinary masterpiece in minutes. It’s almost like uncovering a hidden kitchen superpower you never knew you had.

  • One medium spaghetti squash
  • 1 cup water
  • 1/4 cup parmesan cheese
  • 1/2 tablespoon extra virgin olive oil
  • 1 teaspoon parsley
  • Salt/pepper to taste

Optional for Sauce

  • 1/4 lb hamburger (or ground turkey, or ground veggie sausage)
  • 1 cup tomato sauce (pre-seasoned is good)


Use a sharp blade as opposed to a saw-type to cut the squash. Sawing a squash doesn’t work as well as piercing and cutting with a paring knife . . . trust me!

While your spaghetti squash is cooking, you can make the sauce (optional). Spray a pan with cooking spray and cook your meat on medium-high heat until cooked through. Add tomato sauce and let simmer until done.
