Activate the “Sauté” function on the Instant Pot. Add 2 tablespoons of olive oil and allow it to heat.
Sear the roast.
Once the oil is hot, place the chuck roast in the pot. Sear for approximately 5 minutes per side, until a golden-brown crust forms. This step enhances the overall flavor of the dish.
Deglaze and add broth.
Pour the beef broth into the pot to deglaze the bottom. Gently scrape up any browned bits to incorporate into the liquid.
Season the vegetables.
In a large mixing bowl or zip-top bag, combine the baby carrots, chopped onion, and quartered baby potatoes. Add the remaining 2 tablespoons of olive oil and the French onion soup mix. Toss or shake until the vegetables are evenly coated.
Arrange the vegetables.
Place the seasoned vegetables around and on top of the seared roast inside the Instant Pot.
Seal and cook.
Secure the lid and ensure the steam release valve is in the “Sealing” position. Select the “Manual” or “Pressure Cook” function and set the timer for 70 minutes on High Pressure.
Release pressure.
Once the cooking cycle is complete, allow the pressure to release naturally for 10 minutes, then perform a quick release to release any remaining steam.
Serve.
Carefully open the lid. Remove the roast and shred it using two forks. Serve with the cooked vegetables and ladle broth over the top, if desired.
