These Slow Cooker Porcupine Meatballs are tender, hearty, and cooked in a rich tomato sauce. The “porcupine” name comes from the rice, which pokes out of the meatballs as it cooks.

Serves: 6
Prep Time: 20 minutes
Cook Time: 6–8 hours (Low) or 3–4 hours (High)
Ingredients
Meatballs
- 1½ pounds (680 g) lean ground beef
- ½ cup uncooked long-grain white rice
- 1 small onion, finely diced
- 1 egg
- 2 cloves garlic, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon Italian seasoning
- 2 tablespoons chopped fresh parsley (optional)
Sauce
- 2 (15-ounce/425 g) cans tomato sauce
- 1 (14.5-ounce/410 g) can diced tomatoes, undrained
- 1 cup beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon brown sugar
- 1 teaspoon paprika
Instructions
- In a large bowl, combine the ground beef, uncooked rice, onion, egg, garlic, salt, pepper, Italian seasoning, and parsley. Mix gently until just combined.
- Shape into 1½-inch meatballs (about 18–20 total).
- In a separate bowl, whisk together the tomato sauce, diced tomatoes, beef broth, Worcestershire sauce, brown sugar, and paprika.
- Pour a little sauce into the bottom of the slow cooker.
- Arrange the meatballs in a single layer if possible, then pour the remaining sauce over them.
- Cover and cook:
- Low: 6–8 hours
- High: 3–4 hours
- Check that the meatballs are cooked through and the rice is tender before serving.
Tips
- If your rice seems a little firm, add an extra ¼ cup of beef broth and cook for another 30–60 minutes.
- Lean ground beef (85–90%) works best.
- For extra flavor, stir a handful of grated Parmesan into the meat mixture.
