Ingredients

  • 3 lb sirloin tip roast
  • 2 tablespoons olive oil divided
  • 2 teaspoons Montreal steak seasoning
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1 large onion halved and thickly sliced
  • 4 cloves garlic minced
  • 2 cups beef broth divided
  • 1 pound potatoes cut into 1-inch pieces
  • 4 large carrots chopped into 1-inch chunks
  • 2 tablespoons worcestershire sauce

For Gravy

  • ¼ cup cold water
  • 2 tablespoons cornstarch

Instructions
 

  • Press the Saute button on a 6- or 8-quart Instant Pot. In a small bowl stir together steak seasoning, salt, and pepper. Rub mixture all over the roast to coat all sides.
  • Heat 1 tablespoon of oil in the inner pot, then place the roast in the pot. Sear the beef for 3-4 minutes on each side, until the whole roast is evenly browned. Remove the roast and set it aside.
  • Heat the remaining oil, then add the sliced onions and saute for about 3 minutes. Add in minced garlic and saute for 30 seconds, until fragrant.
  • Press the Cancel button, Pour ½ cup beef broth in Instant Pot, then deglaze by scraping the brown bits off the bottom of the pot with a wooden spoon.
  • Return the roast to the pot. Arrange the potatoes and carrots around the roast, then pour the remaining beef broth and Worcestershire sauce over everything. Close and secure the lid and pressure valve.
  • Press the Manual button, toggle to high pressure, and set the timer for 10 minutes.* When the cooking time is up, allow a 3-minute natural release, then carefully release the pressure valve. When the pin drops, remove the lid. Use a meat thermometer to measure the temperature of the roast's thickest part. (For medium-rare roast beef, aim for 120 degrees F.**
  • Transfer the roast, potatoes, onions, and carrots to a platter to rest. Press the Saute button on the pot. Whisk together the cold water and cornstarch. Once the broth is boiling, stir in the cornstarch mixture until the gravy thickens, seasoning to taste as it simmers.
  • Serve gravy poured over roast and veggies and enjoy!

Notes

*If using a 3QT Instant Pot cook for 5 minutes. If using an 8QT pot, cook for 15 minutes
** If the temperature is too low, remove the vegetables, but return the roast beef back to the pot and close the lid. Use the "keep warm" mode to continue to slow roast the beef until it reaches the ideal temperature, checking every 5 to 10 minutes.

How to Cook Frozen Sirloin Tip Roast in the Instant Pot:

1. Add the Montreal steak seasoning, salt, and pepper to roast and sear both sides of the beef. Place the meat in a sealed zipper bag and freeze.
2. When you are ready to cook, start at step three above. Place the frozen meat in the pot and arrange the veggies, broth, and Worcestershire. Close the lid and pressure valve.
3. Turn to manual high pressure, and set the timer for 40 minutes. Complete a
10-minute natural release and check the internal temperature of the meat. If it’s not done, turn to the “Keep Warm” setting and allow the beef sirloin tip roast to finish cooking. 
4. Prepare the gravy as shown in the above recipe and serve as directed. Enjoy!
