Sirloin Tip Roast in the Instant Pot

Step 1

Season the beef with the kosher salt and black pepper on all sides. Set aside on a plate.

Step 2

Turn the Instant Pot to SAUTE mode, then add 2 Tablespoons of olive oil to the pot and allow the oil to heat up a bit, for about one minute. Add the seasoned beef to the pot and sear on all sides, just until all sides are browned. Remove the beef roast and transfer to a plate; set aside.

Step 3

Add the remaining tablespoon of olive oil to the pot, then add the onions and garlic and sauté for 1-2 minutes, just until the vegetables are soft and fragrant.

Step 4

Press CANCEL to turn the saute mode off. Pour in about ¼ cup of beef broth and use a wooden spoon to deglaze the pot by scraping up any browned bits at the bottom. This helps you avoid the BURN warning notice that can happen if there are bits of food stuck to the bottom of the pot.

Step 5

Place a trivet or a silicon sling into the pot over the garlic and onions, then place the seasoned and seared beef on top of the trivet or sling.

Step 6

Add the carrots and potatoes to the pot around and even on top of the roast.

Step 7

Pour in the remaining beef broth and the Worcestershire sauce.

Step 8

Secure the lid, making sure the pressure valve is set to SEALING position. Select PRESSURE COOK (or MANUAL), HI temperature, and set the time to 15 minutes.

Step 9

It will take a few minutes for the electric pressure cooker to come to pressure, and then once pressure cooking starts it will count down from 15 minutes. Once pressure cooking is complete, the Instant Pot will beep, and you'll do a Natural Release (meaning: do nothing and allow pressure to release naturally) for 3 minutes. After 3 minutes, use tongs or oven mitts to very carefully do a Quick Release: moving the pressure valve to the VENTING position and allowing the steam to release.

Step 10

Once all of the pressure has been released, the pressure release pin will go down. Then you can safely but still very carefully twist the lid to open it. Remove the roast and vegetables and transfer to a plate.

Step 11

Press SAUTE and add the cornstarch to the remaining liquid in the pot. Whisk vigorously so there are no clumps of cornstarch, and allow to come to a low boil as the gravy thickens.

Step 12

Once the gravy has thickened up to your liking, press CANCEL to stop the saute mode.

Step 13

Use oven mitts to remove the Instant Pot and strain out the gravy over a heatproof bowl or large measuring cup with a spout (this makes it easier to pour). Discard any solids in the strainer and pour the liquid into a gravy boat or other serving container. Serve with the sirloin tip roast and vegetables.
