In a small bowl, combine seasoning salt, garlic, parsley, onion powder and pepper. Sprinkle over roast to season.
2 tsp seasoning salt, 1 tsp garlic powder, 1 tsp dried parsley, ½ tsp onion powder, ½ tsp black pepper
Turn Instant Pot to saute. When it reads hot, add the oil and sear roast on all sides. To do this, place the roast in the pot and do not move for 2-3 minutes. When you flip it, it should release from the pan easily. You may need to add extra oil to brown all of the pieces and cook them in 2 batches. When browned, removed the meat from the Instant Pot.
3 lbs beef chuck roast, 2 tbsp canola oil
Add the onion and cook, stirring, until softened (adding more oil if necessary). Add the garlic and cook 1 minute.
1 medium onion, 3 cloves garlic
To the Instant Pot add broth, vinegar, tomato paste, and Worcestershire sauce -- if there are brown bits stuck to the bottom from the meat, give them a scrape with a wooden spoon and they should release easily -- this will help to prevent a burn message. Stir to combine.
2 c beef broth, 3 tbsp balsamic vinegar, 2 tbsp tomato paste, 2 tbsp Worcestershire sauce
Add the meat back into the pot. Put the lid on and turn the valve to sealing. Select Manual or Pressure Cook and set the cook time for 65 minutes on high pressure (90-100 minutes for a frozen roast).
When the cook time is over, turn the Instant Pot off and let the pressure release naturally (this should take 10-15 minutes) before turning the valve to venting and opening the lid.
Remove the roast to a plate, cover and let rest for 10 minutes. Add the potatoes and carrots, put the lid back on, turn the valve to sealing and select Manual or Pressure Cook for 3 minutes.
1 ½ lbs creamer potatoes, 3 large carrots
While the potatoes and carrots cook, shred the beef and keep warm.
When the cook time is over, let pressure release naturally for 5 minutes before moving the valve to venting, gradually releasing remaining pressure and opening the lid.
Remove potatoes and carrots from Instant Pot and place on a platter with the beef.
Stir in ketchup (it's not necessary but as a nice brightness and contrast to the savory flavor of the beef). Whisk together corn starch and water and stir into gravy.
1 tbsp ketchup or honey, 2 tbsp corn starch, 2 tbsp water
Turn Instant Pot to saute and cook, stirring often, until gravy has thickened. Serve with roast beef and vegetables.
