Step 1

Season meat with salt and pepper. Heat oil in the Instant Pot on the saute mode. Saute the roast on all sides for 2-3 minutes each until browned. Whisk the remaining ingredients together in a separate bowl. Pour over the roast.

Step 2

Set the instant pot to cook on HIGH pressure for 70 minutes, followed by a quick release. Transfer the pork to a plate to slice or shred.

Step 3

Whisk cornstarch and water together in a small bowl. Pour the liquid from the Instant Pot into a fat strainer to remove the top layer of fat that is cooked off the pork roast. Return the juices to the Instant Pot.

Step 4

Switch back to the SAUTE setting. Whisk the cornstarch slurry into the liquid and cook for 3 to 4 minutes until slightly thickened. Pour as much of the sauce over the meat as you would like. Serve over mashed potatoes.
