DISCLAIMER: I developed and tested this recipe in my 6-QUART INSTANT POT DUO. If you’re using a larger IP or a newer brand you may need to add more liquid so that you don’t get a burn notice. (The new IP are much more sensitive). Not all instant pot recipes work perfectly for all types of instant pots. See this article for more information on adapting recipes for your instant pot.
Add meatballs to bottom of IP. Add pasta on top, spreading into an even layer.
Pour water over pasta.
Add crushed tomatoes, seasonings and tomato sauce and gently stir with a spoon. Smooth the sauce to completely cover the noodles.
Cook on High Pressure (Manual) for 4-5 minutes (half the time on the box of pasta).
Do a controlled quick release when timer beeps. Stir. Allow to cool for 5-10 minutes before serving.
