Place roast in greased the Instant Pot. Pour consommé over the top of the roast.
Put the lid on and turn the knob to sealing.
Push the manual or pressure cook button and set the timer for 75 minutes (25 minutes per pound of roast).
When it is done cooking, let it do a natural release for at least 1 hour. This will make your meat very tender and fall-apart, so I highly recommend it! (Sometimes I will let the roast sit in the Instant Pot on warm for 6-8 hours and it makes it SO good!) Turn the valve to venting to let any remaining pressure release.
Remove roast and save extra juice for dipping! With 2 forks, shred roast (when it is done, it should pull apart easily . . . almost fall apart).
Serve meat on buns and use extra juice to dip sandwiches in.
Notes
*What to do if you can't find beef consomme:
As a substitute, you can use condensed French Onion soup, condensed Beef Mushroom soup, or even beef broth.To take this recipe over the top, add 1 Tablespoon Worcestershire sauce, 1 Tablespoon soy sauce, 1 Tablespoon balsamic vinegar, 1 teaspoon dried thyme, and 1 teaspoon dried rosemary.
