Set the Instant Pot to Saute. Add the oil and brown the meat in 2 batches. Cook each batch for 2 or 3 minutes, turning the pieces of beef several times so all sides are browned. Set the browned meat aside.
Turn off the Instant Pot and add the onion to the warm pot. Let it cook for a minute, stirring a few times. Then add all the remaining ingredients to the pot, including the browned meat.
Close the lid, set the seal, and press the Meat/Stew button, which will set the pot to 35 minutes.
After the 35 minute cook time, use a natural pressure release. Wait until the silver pressure indicator drops on its own (about 30 minutes). This will allow the beef to maintain as much moisture as possible. (Note: If you're in a hurry, you can let the pressure release naturally for just 10 minutes, then release the remaining pressure by turning the vent.)
