Step 1

Press the SAUTE button. Add in the butter and let it melt.

Step 2

Add in the ground beef, red pepper, and red onion and cook, using a spatula to break up the meat.

Step 3

Press CANCEL.

Step 4

In a bowl, mix together brown sugar, red wine vinegar, steak seasoning, Worcestershire sauce, and tomato sauce.

Step 5

Pour sauce on meat in Instant Pot and stir to combine. If you are worried about getting the "burn notice" on your Instant Pot, use a wooden spoon to scrape the bottom of the Instant Pot and loosen up any burned or brown bits on the bottom of the pot (aka deglazing the pot).

Step 6

Place the lid on the Instant Pot and secure in place. Turn the vent to SEALING. Press the MANUAL button and set the timer for 8 minutes.

Step 7

When cooking is finished, let the pressure NATURALLY RELEASE for 10 minutes and then move the vent to VENTING and release the remaining pressure.

Step 8

Remove the lid and stir to make sure everything is mixed together, then serve meat on hamburger buns.
