This super Easy Instant Pot Beef Stew will have you grabbing a second bowl! A thick and rich sauce filled with hearty potatoes, carrots, onions, and melt in your mouth beef that will only take under an hour with an Instant Pot!
In a large bowl, mix together your stew beef, flour, salt (lightly!), and pepper.
Set your Instant Pot to sauté - low. Add your butter and lightly brown your beef. It doesn't have to be cooked all the way through, just browned. Because I had 2.5lb/1.15kg of beef for the beef stew, I had to do this in two batches because I didn't want to overcrowd the pot and have burn marks at the bottom.
Add into the Instant Pot 2.5 cups of beef broth/stock (deglaze the pot if you have to, to avoid any brown bits from browning the beef from burning), Worcestershire sauce, soy/tamari sauce, garlic, brown sugar, tomato paste, and rosemary.
Add in the potatoes, onions, carrots, and mushrooms.
Close the Instant Pot lid, close the steam valve, and set the Instant Pot to Meat/Stew or Pressure Cook for 35 minutes on High. (Note it could take up to 10 minutes for the Instant Pot to build up pressure)
Once done, either let the Instant Pot naturally release or (as I did) quick release the lid. Serve while warm. (Optional parsley for garnish)
If you notice that your stew is a bit too liquidly, the stew should thicken a bit once it cools. If it doesn't, you can add some stew liquid into a separate bowl, add a tablespoon of flour or cornstarch, stir then add the thickening mixture back into the main pot.
