Step 1

Peel and cut potatoes. Place them in a steamer basket for the Instant Pot or they can be placed around the meat before putting the lid on.

Step 2

Pour olive oil into Instant Pot and set to saute function. Sprinkle 1 tsp of the Montreal Steak Spice over the oil in the Pot.

Remove the roast from the Pot.

Step 5

Add the beef broth and scrape the bottom of the pot very well to deglaze.

Place the steamer basket with the potatoes on top of the roast.

Step 8

Place the lid on the Instant Pot, turn the steam release handle to the sealing position and set the Instant Pot to Pressure Cook High for 32 minutes.

When the Instant Pot is done cooking, allow it to natural release for 8 minutes. Then turn the steam release handle to the venting position to finish with a quick release.

Step 10

Using oven mitts carefully remove the potatoes and the roast.

Step 11

Pour the broth into a measuring cup. Use 2 cups of broth and add the two packets of gravy mix to it.
