Instant Pot BBQ Beef Brisket

0 Whisk together all ingredients for the dry rub until fully incorporated.
1 Cut brisket into 3-4 equal pieces, then season the brisket with the dry rub mixture, making sure it's applied liberally and applied to all sides.
2 Add the butter or oil to the Instant Pot, and turn to "saute" mode.
3 Once hot, add the beef to Instant Pot in two batches, searing brisket for 3-4 minutes per side until browned, then remove from pot. Note: searing the beef all at once will cause overcrowding and will prevent the beef from browning nicely.
4 Once all beef is browned, pour in the broth and scrape the browned bits on the bottom with a whisk, then add the beef back to the pot.
5 Close the instant pot, making sure the valve is set to "sealing" rather than "venting." Set to cook on high pressure for 70 minutes.
6 Once the brisket is finished cooking, let the Instant pot release pressure naturally (about 15 minutes) until the lid easily opens.
7 Slice the beef against the grain and serve with BBQ sauce. Garnish with sea salt and cilantro, if desired. Enjoy!
