Put flour, garlic powder, onion powder, and black pepper into a ziptop bag.
Add cubed stew meat, and shake to coat your beef with the flour mixture
In the instant pot, add olive oil and heat the saute setting. Once it reads hot, add beef, and sear the exterior of the beef to lock in flavors.
Add ½ cup of beef stock or red wine and deglaze the pot by using a wooden spoon to scrape the bottom removing anything stuck on or any brown bits.
Add the remaining ingredients except corn starch to the instant pot.
Put lid on, and lock into place, turn valve to sealing.
Cook on High Pressure/Manual using the stew/meat setting for 35 minutes.
Let the pot natural pressure release.
Remove lid, and dip a ladle into the pot, and remove ½ a cup of liquid, pour it into a small bowl, and make a slurry using the corn starch. Add the slurry into pot, and stir well, then turn pot to “Saute” setting and simmer until desired thickness is reached.
Add fresh parsley on top for garnish.
