Instant Pot Spaghetti Squash Chicken Parmesan

Recently, my parents gifted me with a pressure cooker. Since then, it’s become my favorite go-to kitchen appliance. I love that I can use it to make entire meals in just one pot. Plus, I have the ability to sear meats right in that one pot, which really locks in the flavor. I can also use mine as a slow cooker if I want to. It’s so easy!

Instant Pot Spaghetti Squash

This recipe started with an idea. I know that spaghetti squash can be cooked in a slow cooker. However, I wasn’t sure about cooking it in a pressure cooker. I assume that it can be done in the pressure cooker by poking some holes in the squash, adding some water and cooking. I also figured that I could poke holes in it, and throw it in the pot with the rest of my ingredients for this recipe. With that method, however, you have to take the spaghetti squash out of the pot once it’s cooked. Then clean it off, cut it open and scrape out the insides. You could also cut it in half, add some water to the pot, and place the squash on the steamer tray to cook.

So, I chose to cut the squash in half, scrape out the seeds, and scrape the strands into the pot before cooking. This was a bit tougher to do up front, but I think it works perfectly in this recipe. The water that the spaghetti squash releases added just enough liquid to the sauce to keep things from getting mushy.
