Instant Pot Spaghetti Squash

If you’ve stared at those big canary-yellow spaghetti squash in the produce aisle and wondered how on earth it could be transformed into anything resembling spaghetti, your Instant Pot will allow you perform culinary alchemy.  No spiralizers or other gadgets needed – and you’ll save time and the risk of slicing your finger!

Spaghetti Squash in the Instant Pot

And, I know you’re wondering – does it taste like spaghetti?   Well, yes….and no.  Once it’s cooked in your Instant Pot, the yellow flesh of this squash will separate into long thin, spaghetti-like strands.  The texture is like angel hair pasta —  tender and chewy, and a bit fragile.  The flavor is very mild, almost bland, just like pasta is – the perfect base for any Italian or Asian dish using pasta or noodles.  It’s nothing like the flavor of acorn or butternut squash.   That said, even though Mother Nature has given this squash some spaghetti-like attributes, it is still a squash. It looks like pasta, has a texture like pasta, and a similar taste, but it’s probably not going to fool anyone.  The good news is that once you’ve served Instant Pot Spaghetti Squash, both you, and your kids, want it again and again.

Pressure Cooker Spaghetti Squash

Recipe tips:  If you cut the squash in half before putting it into the Instant Pot, it will cook faster (just 15 minutes)  than if you leave it whole (25 minutes). Plus, you can use the seeds just like pumpkin seeds – roasted as a low-carb snack, or tossed on a salad.  Spaghetti squash can sometimes be a challenge to cut though, so if you have trouble cutting it, just throw it in whole :)

Instant Pot Whole Spaghetti Squash

There are so many good things about this Instant Pot Spaghetti Squash, that you might be tempted to never cook “real” spaghetti again.  Spaghetti squash is paleo.  It’s  gluten-free. It’s low calorie and low-carb – a cup has only 40 calories and 10 grams of carbs, compared to wheat pasta, which has 200 calories and 40 grams of carbs!
