Instant Pot Spaghetti Squash
A few years ago, I was on a very healthy eating regime and working on shedding some extra pounds. I ended up going Paleo for about 6 months. It really helped me lose the last 23 pounds, and was a great learning experience.
On my Paleo journey is when I learned about the Instant Pot. I thought it would be a perfect appliance to help me cook meat and some veggies in a healthier way. And I have used it ever since!
I also learned was what a spaghetti squash was. Oh boy was that life changing for me! I used to make a lot of meatballs, and my own sauces, so to be able to put them over spaghetti squash instead of pasta was amazing! So healthy and delicious!
To make spaghetti squash in the Instant Pot, start with cutting the squash in half. I do so across the diameter as both halves fit in the pot better. Scrape out the seeds with a spoon and discard (or roast them like pumpkin seeds!).
Then put 1 ½ cups of water into your pot, then the trivet, and put the squash halves on the trivet. Then put the lid on and cook on High pressure. Then use a fork to scrape out that wonderful Instant Pot Spaghetti Squash!
Speaking of moderation, you might like to pair the spaghetti squash with my Garlic Parmesan Cream Sauce! It's decadent and so good! It's a little healthier because you are having it over a veggie!

Larger or smaller squashes may need more or less time. If you like a crunchier result, shorten the cook time by a minute or two. You may need to experiment a little to get your perfect tenderness. If you aren't sure, just cook one half of the squash first and use that as a test.

This was so easy and the squash cooked way faster than how I was making it in the oven. Points for not having to turn on the oven in this Utah heat!
