I never thought I could get so excited about spaghetti squash! This recipe all started when I was working on another recipe that included spaghetti squash. I often bake or steam spaghetti squash, but it’s hot here in North Carolina. I couldn’t stand the thought of heating up the oven or steaming up the kitchen. On a whim, I decided to try to make it in the Instant Pot. The results were so good, I wanted to share this recipe with you as it’s own recipe. 

The Instant Pot:

I’ve had my Instant Pot since Christmas and I find myself using it more and more. At first, I was afraid of it. I had heard stories about pressure cooking accidents. Seriously, the first time I released the steam vent I screamed. I wasn’t expecting a geyser of steam to shoot up from the pot! Now that I’m over that initial nervousness, I have found that with every use, I grow more and more fond of it.

So far, I’ve used my Instant Pot mostly for soups like my Low-Carb Italian Sausage Soup-Instant Pot Recipe, roasts, and one low-carb lava cake. I love how tender it makes the meat. While meat cooked in the Instant Pot has that slow-cooked fall-apart tender, it retains its flavor better than it does if it’s cooked for hours. In fact, I find I go to my Instant Pot more and more instead of using my slow-cooker. This is one appliance that has earned it’s space in my kitchen.

One thing I haven’t used the Instant Pot for is steaming veggies. It’s a little hard to break away from the stove top steamer I know so well and love more than it’s healthy to love a piece of kitchen equipment.

As much as I love my stove-top steamer, after making spaghetti squash in my Instant Pot, I’m starting to think about trying the Instant Pot for other veggies. It may just be time to invest in a steamer basket for smaller veggies like broccoli. For this recipe, however, a steamer basket is not required. Instead, you can use the steam rack that comes with the pot.

The recipe:

As I was moving into uncharted territory (in my kitchen, at least), I consulted the recipe booklet that came with the pot to get an idea for the settings to start with. While their aren’t any recipes for spaghetti squash in the book, I decided to start with the same time and pressure as they use to cook the butternut squash for their Ginger and Butternut Squash Soup recipe.

The time turned out to be spot-on. This Instant Pot Spaghetti Squash recipe makes tender spaghetti squash that separates easily into noodles. The noodles have an almost al dente texture. I can’t stop raving about the noodle texture. Drench these babies with sauce and twirl them with a spoon! These noodles hold up! Seriously, I’ve never had so much fun taking photos of spaghetti squash!

Instant Pot Spaghetti Squash

In conclusion:

This recipe for Instant Pot Spaghetti Squash makes squash noodles that are tender and easily separated into noodles. They would be perfect with this Garlic Parmesan Cream Sauce from Wholesome Yum, my Low-Carb Beef Stroganoff,this  low-carb bolognese sauce from Sugar Free Londener or your favorite topping. These noodles make a healthy and delicious nest to fill with your favorite low-carb pasta sauce. Enjoy!

  7. When time is up, release pressure using the quick release method. Consult the manual for more information on how to do this.  After the pressure has been released and the float valve has dropped, remove the lid carefully as steam will come out. Remove the squash form the Instant Pot using tongs. Use a fork to fluff out the noodles and remove them from the squash shell.

  8. Squash may be served immediately, or refrigerated in an airtight container to use later. If using later, reheat briefly to avoid overcooking.
