Pressure Cooker Spaghetti Squash with Pesto

"Select a medium sized squash that will fit into the pressure cooker even when cut in half. If the squash is larger, simply cook it in two batches. I have easily converted this recipe to oven with the same results"

    Yum. I had already started baking the squash in 1/2 an inch of water at 350 when I found this recipe. I wanted to find out if anyone else thought spaghetti squash would be good with pesto, and this gave me the confidence to try it. I added grated jack cheese to the top, and my hubby and I were both soo delighted. I want more, but have to save it for my son when he comes home. I could eat a whole spaghettin squash this way. I will definitely do this again.

    The spaghetti squash should have the seeds scraped out prior to cooking, this is easier. Also the cook time is way off, I cooked for 10 and it was really mushy and over done. I served this over a basil linguine and topped with a spicy tomato sauce. I will make it again with maybe 7 minutes cook time in the pressure cooker.

    A great recipe, however removing those seeds were keeping me from enjoying it once it was ready to throw together!

    This was my first try of spaghetti squash and I think the texture was not what I was expecting. I baked mine in the microwave after removing the seeds. I'll try this again.


I live in Las Vegas. I was lucky enough to run into Recipezaar around Nov. 2000 and got hooked quickly. I am a cookbook collector and have been collecting recipes for as long as I can remember. My DH had to build in shelves for all my cookbooks! I like to dabble with OAMC and for a few years hosted the Budget/OAMC forum with some great people over there. Even though I don't work in the forum any longer I've set up a lot of cookbooks for the purpose of OAMC and stretching food that might be helpful. Please feel free to check them out! I go on food jags and cooking jags! Please come say hi to me and chat on facebook. I currently host a blog for saving money through finding deals and coupons if you are interested. Most of the time I try to cook and have a good dinner on the table but I'll be honest enough to say there is still fast food occasionally in the budget! I have had such wonderful support here whenever I need it. Thank you all for being here! Just a quick note on how I rate recipes: ? 5 stars - This recipe is perfect. (My DH is truly a critic and doesn't give 5's unless it's amazing) I would recommend it to others and would definitely make again. ? 4 stars - This recipe was good but I would change something in it next time. ? 3 stars - This is a recipe I would not make again but it was OK ? 2 stars - This recipe I would not make again and we didn't like it at all ? 1 star - This recipes did not work out/taste was unappealing and wouldn't make again
