Step 1

In a bowl, combine the egg, rice, onion, parsley, salt and pepper. Crumble the ground beef over the rice mixture and mix them together lightly but thoroughly. Shape the beef mixture into 1 ½-inch balls. Arrange the meatballs on a trivet in a 6-quart electric pressure cooker. Combine the condensed soup, water and Worcestershire sauce, and pour this mixture over the meatballs.

Step 2

Lock the pressure cooker’s lid and close its pressure release valve. Set it to cook for 10 minutes at high pressure. Once the 10-minute cooking cycle is complete, quick-release the pressure. Let the meatballs stand for 5 minutes before serving. If desired, serve the meatballs over rice and top them with additional chopped parsley.
