Equipment

  • Instant pot

Ingredients

  • 2 tablespoons olive oil
  • 3- pound rump roast
  • 1 teaspoon sea salt
  • ½ teaspoon freshly ground black pepper
  • 1 celery stalk chopped
  • 1 yellow onion chopped
  • 1 cup beef broth
  • 1 tablespoon balsamic vinegar
  • 2 tablespoons soy sauce
  • ¼ cup all-purpose flour

Instructions

  • Season the rump roast generously with salt and pepper on all sides. Heat the olive oil in your Instant Pot on the “Sauté” setting. Once the oil is hot and shimmering, carefully add the roast and sear for 2-3 minutes per side or until browned.
  • Add the celery, onion, beef broth, balsamic vinegar, and soy sauce to the Instant Pot. Cook on high pressure for 45 minutes. (adjust time based on your roast's size)
  • Once it's done, allow the pressure to release naturally for at least 10 minutes. After 10 minutes, you can carefully release any remaining pressure manually.
  • Remove the roast and veggies from the Instant Pot and transfer it to a cutting board. Tent the roast with foil and let it rest while we make our gravy.
  • Set the pot to “Sauté” mode. Bring the remaining liquids in the pot to a simmer, scraping up any browned bits from the bottom. Slowly whisk the flour into the simmering liquid in the Instant Pot, continuing to whisk until the gravy thickens to your desired consistency.

Notes

For a fully defrosted roast, set out for an hour ahead of time
I usually cook my roasts for about 15-20 minutes a pound with a slow pressure release. Remember, it's crucial to check the internal temperature before consuming, as this ensures your roast is perfectly cooked.
Ensure a good sear on all sides of the roast to create a delicious crust and help lock in the juices.
For a richer gravy, consider using a cornstarch slurry instead of flour. This can prevent lumps and create a smoother texture.
