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.

  • I’ve been starting my mornings by adding two scoops of collagen to my coffee every morning. It has tons of body and beauty benefits. ☕️☕️☕️
  • Real talk: my kids are one today. They had the house trashed by 8 this morning. Luckily for me, these Blueberry Crumb Bars from @lexiscleankitchen just came out of the oven.
So, I’m going to sit on my backside on the couch and enjoy a slice while those little monsters clean their room. 😉And I don’t feel the least bit of guilt about it.
  • Usually, the tiny humans are the only things I can keep alive but I’m doing pretty well with the container garden this year. 🎉
  • I stole this little gem from @belleandbell. In case someone else needs to read it. 😉
  • Apparently purple bell peppers exist! I was excited when my husband found this plant at @homedepot, and I’m even more excited that I haven’t killed it yet! 🎉 This will be a great way to help us eat the rainbow!
  • “I want to be strong like my mom.” That’s what my oldest told her gymnastics coach on the first day of lessons. Working out is as much for them as it for me. It makes me stronger, healthier, more patient, more energetic. It sets the right example for them. They see what a body is capable of. They see that women are strong. They see what hard work looks like. Yes, I do it for me, but I do it for them, too, and apparently, they are getting it. 🏋🏼‍♀️🤸‍♂️
  • I wanted salad for dinner tonight, so I made salmon burgers, topped with a mango salsa. I had mine on a pile of arugula and spinach and the rest of the family had theirs on buns. 😉Win-win
  • Woo-hoo!
  • Props to all of those ladies that can workout and still look cute. I am not one of them. 😂🤣Also, @erinoprea might be trying to kill me with her do anywhere workouts. 😂🤣😂🤣You should give them a try.
