Set pot to saute and add 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.
Pour 32 oz. 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.
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. Will continue to thicken as it sits. Serve.
