  • Set a 6-qt Instant Pot® to the sauté setting. Season the meat with salt and black pepper. When the pot is hot, add olive oil and beef. Cook for about 5-7 minutes or until the meat is browned on all sides. Remember to stir occasionally.

  • Put on the lid, lock it and check to see if the vent is at sealing. Then, select manual setting; adjust pressure to high, and set time for 15 minutes. Mine took about 15 minutes to reach pressure. After the 15 minutes is up, let it naturally release pressure for 10 minutes. Then, do a Quick Release, which means move the valve to venting to release the steam. When all the steam is gone, open the instant pot and add the arrowroot flour.
  • Mix all well and serve with mashed potato. Enjoy!
