Remove lid and press Brown/Saute. Press Start/Stop and allow the pot to heat up completely while you prepare the meat. (This takes just over 5 minutes and then the 30 minute cook time will start counting down.) Unwrap your roast and rub both sides with seasoning (salt and pepper or your favorite beef rub.)
Cut the meat into two equal pieces. Once the pot is heated completely, add the oil and make sure it's spread around the bottom of the pot. Using silicone tipped tongs, place ONE of the pieces of the roast on the bottom of the pot. Do not move it. Allow to sear for 10 minutes on one side, then flip and sear for another 5-10 minutes. Remove the first chunk of meat and repeat the process with the second.
After both of your pieces have been seared on both sides, remove them and let them rest while you prep the sauce. (Leave the CPE on Brown/Saute) Add the garlic and sliced onions to the pot and saute for a few minutes until soft. Then stir together the vegetable stock, beef bouillon cube and soy sauce until mixed well. Pour into the onion/garlic mixture and use it to "deglaze" the pot. Stir well, scraping up all those beautiful bits of beef left over from searing. Press Stop/Start to cancel the Brown/Saute mode.
Place both chunks of seared meat back down into the sauce. Don't stack them on top of each other. They should fit side by side. Close the lid, lock it, and set the Steam Release Valve to closed. Press Meat and adjust time to 45 minutes.
When the cooking cycle ends, allow for a full natural pressure release. (At least 25 minutes.) After the NPR, open the lid and remove the meat. DO NOT SLICE IT YET! Allow it to rest under a foil tent while you make the potatoes and carrots.
Place the potatoes and carrots directly in the cooking juices. Put the lid back on, twist to lock and close the steam release valve. Press Steam and set for 5 minutes. After the cooking cycle is done, do a Quick Release remove from the pot.
Slice roast. Cut against the grain to keep it tender. Place it on a serving dish and surround with carrots and potatoes. Drizzle with additional drippings or gravy.
Notes
Cutting the meat into even pieces is very important. This will help with more even cooking and keep the pot from getting too crowded while searing the meat. It needs room to breath so you get a great sear on the outside.While searing, you may need to restart the Brown/Saute cycle if you reach the end of the 30 minute timer. Don't let it go to Keep Warm! Just press Start/Stop, then Brown/Saute again and start over. It won't take time to heat back up since it's already hot.Because the pot is already warm, it won't take long for it to come back to pressure after removing the meat and adding the vegetables. It should be ready in less than 5 minutes.
