Step 1

Mix the broth, onion, Worcestershire sauce, and garlic in an Instant Pot. Set the pot’s rack (with the handles up) or a large, open vegetable steamer inside the pot. Set the frozen chuck roast on the rack or in the steamer. Sprinkle the top of the meat evenly with the paprika, onion powder, thyme, and pepper. Lock the lid onto the pot.

Step 2

Step 3

Option 2 All Pressure CookersPress Meat/Stew, Pressure Cook or Manual on High pressure for 1 hour 30 minutes (90 minutes) with the Keep Warm setting off. The valve must be closed.

Step 4

Use the quick-­release method to bring the pot’s pressure back to normal. Unlatch the lid and open the cooker. Use kitchen tongs, silicone cooking mitts, or thick hot pads to remove the rack or steamer from the cooker, letting the chuck roast fall into the sauce below. Scatter the root vegetables over everything. Lock the lid back onto the pot.

Step 5

Press Meat/Stew, Pressure Cook or Manual on High pressure for 10 minutes with the Keep Warm setting off. The valve must be closed.

Step 6

When the machine has finished cooking, turn it off and let its pressure return to normal naturally, about 30 minutes. Unlatch the lid and open the cooker again. Using a large slotted spoon or large metal spatula and a meat fork, transfer the chuck roast to a nearby cutting board. Cool for a couple of minutes, then slice the meat into chunks to be served with the vegetables and sauce from the pot.
