Gather all ingredients.
Mix ground beef, rice, water, onion, salt, celery salt, garlic powder, and black pepper thoroughly in a bowl until well combined. Roll mixture into 12 meatballs.
Heat oil in a large skillet over medium-high heat. Place meatballs into the hot skillet; cook, turning once halfway through cooking, until well browned, about 8 minutes. Drain and discard excess grease.
Pour tomato sauce, chicken stock, Worcestershire sauce, and sugar into the skillet; reduce heat to medium-low. Cover and simmer until meatballs are no longer pink in the center and rice is tender, about 45 minutes. Stir in more stock if sauce becomes too dry.
Enjoy!
