Alright, listen up nerds, I'm about to share the best goddamn instant pot soup recipe. I hardly measure shit, so bear with me. You'll probably want a 6 quart instant pot at least for this.
Start off with four cups of chicken stock (you can use bullion, doesn't matter much, but if you have stock that's great). Add in a bunch of basil, oregano, and maybe parsley too if you feel like it. Herb that shit out. Throw in some salt too. It's really fucking hard to over-season things here.
Then, do you uncultured swine know what mirepoix is? Probably not, but basically it's a 2

1 ratio of diced onion, carrots, and celery. Just eyeball the amounts and roughly dice an onion, some carrots, and some celery. Throw it into the pot.
Roughly dice 2-3 pounds of potatoes to stick some meat on your bones. Throw it into the pot.
Finally, take 2-3 frozen boneless skinless chicken breasts out of the freezer, and put them in on top. You're not thawing shit because honestly, the entire point of buying an instant pot is so that you can cook without putting up with bullshit like thawing chicken.
Pressure cook the shit out of that on high for like 20 minutes (15 probably also works). Boom, soup. Pretty much the entirety of the work is like 5 minutes of dicing things. Don't bother peeling vegetables unless you're trying to get into a girl's pants or impress her mother or something.
