Instructions
Press sauté.
Cut the chuck roast into 4 large chunks, and season with salt and pepper.
Once the Instant Pot reads "hot", drizzle in the olive oil.
Add the chunks of roast and give them a quick sear to brown the outside. Work in batches if necessary, and don't overcrowd the pot as it will steam the meat.
Remove the browned chunks of meat and pour in 1 cup of the beef broth.
Press cancel.
Scrape up any browned bits from the bottom of the pot.
Layer in the sliced onions, browned meat, and sprinkle garlic and rosemary on top.
Close and lock the lid. Press manual high pressure and adjust the cooking time to 60 minutes. Be sure that the pressure release valve is set to sealing. It should take about 15-20 minutes to reach pressure.
Once the cooking time has ended, let the pressure release naturally for 20 minutes, and then turn the pressure release valve to venting to release any remaining pressure.
Remove the meat from the pot and shred. Tent with aluminum foil to keep warm.
In a small dish, stir together the remaining broth with the cornstarch.
Press cancel and then press sauté.
Stir in the cornstarch mixture until well-combined.
Cook, stirring regularly, until the gravy has thickened.
Serve the gravy over the shredded meat.
Notes
Rosemary: If you'd like to use thyme or a mixture of herbs, you can use whatever herbs you like in place of the dried rosemary.
