In a large bowl, combine the ground beef, rice, water, onion, egg, garlic powder, onion powder, worcestershire sauce, parsley and pepper.
Shape the meat mixture into balls approximately 2 inches in diameter and set aside.
Heat the oil in a large skillet set over medium heat. Add the meatballs to the pan and brown on all sides, approximately 8-10 minutes. Drain the fat from the pan and return to the heat.
While the meatballs are cooking, whisk together the tomato sauce, water, sugar, worcestershire sauce, garlic powder, salt and pepper.
Pour the sauce mixture over the meatballs and arrange so all the meatballs are coated in the sauce.
Cover and simmer for 45-50 minutes.
Serve the meatballs with the sauce over rice or mashed potatoes, if desired.
Notes
Meatballs can be made up to 48 hours in advance and stored in an airtight container in the refrigerator.Alternatively, you can freeze cooked porcupine meatballs in an airtight container for up to 3 months.
Retro Baked Sauce (Condensed Soup)
2 cans (10.5 oz each) condensed tomato soup
1 cup water (or V8/tomato juice for extra flavor)
1 tsp Worcestershire sauce
Optional: pinch sugar and Italian seasoning
Instant Pot / Slow Cooker Sauce (quick)
1 (15 oz) can tomato sauce
1 cup beef broth
1 tsp Worcestershire sauce
Optional: 1/2 cup diced tomatoes

Instant Pot: 8 minutes high pressure + 10 minutes natural release Slow Cooker: Low 6–7 hours (or High 3–4 hours)Instant Pot
Add tomato sauce, broth, and Worcestershire to the pot.
Place meatballs in a single, even layer (stack gently if needed—don’t pack). Spoon a little sauce over.
Seal and cook 8 minutes on High Pressure. Allow 10 minutes natural release, then quick release.
If sauce is thin, simmer on Sauté 3–5 minutes. If rice needs a touch more time, cover and rest 5–10 minutes; residual heat finishes it.
Slow Cooker
Whisk sauce ingredients in the crock.
Nestle meatballs in a single layer (a slight overlap is fine).
Cook Low 6–7 hours (or High 3–4 hours) until rice is tender and meatballs are cooked through.
