Set pot to saute and add olive oil. Rub salt and pepper on your meat pieces and add into the pot. (you could add 1 c. sliced onions too)
Brown outsides of meat so they're no longer pink. Then turn pot to off. Pour in a bit of your broth and scrape the bottom to remove stuck on meat bits.
Pour remaining beef broth into pot + all other ingredients EXCEPT potatoes and carrots. Stir together. Close lid and seal vent.
Set to high pressure for 18 minutes.
Allow pressure to naturally release for 5 minutes.
Release rest of pressure, add potatoes and carrots, stir to combine.
Cover and seal vent again, set to high pressure for 4 minutes.
Do a quick release.
If you want to thicken broth you can set pot to saute again. In small bowl add 2 tbsp cornstarch with some of your hot liquid. Whisk together and pour into pot. Stir, allow it to bubble and thicken broth.
Taste, adjust salt and pepper. Will continue to thicken as it sits. Serve.
