1(10.75 oz)can condensed tomato soup, not diluted(use 2 cans of soup for more sauce in the pan)
1soup can of water(use 2 soup cans of water for a "saucier" pan of meatballs)
Instructions
Preheat oven to 350°F. Spray a 2-quart baking dish with nonstick cooking spray and set aside. In a large bowl, combine ground beef, uncooked rice, egg, onion, parsley, salt, and pepper.
Shape the meat mixture into 1-inch balls. Place the meatballs in the prepared baking dish.
In a small bowl, whisk together the tomato soup and water. Pour the soup mixture over the meatballs.
Cover and bake for 30 minutes. Remove cover and continue baking for 30 more minutes. At this point, the meatballs should be cooked through and the rice inside the meatballs should be tender. If the rice is still crunchy, cover loosely with foil and return to the oven for another 5-10 minutes (or until rice is done).
Notes
There is not a lot of sauce in the pan with these meatballs. If you prefer a "saucier" dish, use two cans of soup (and twice as much water). Alternatively, add a jar of marinara sauce to the pan with the tomato soup mixture.
The total cooking time will vary depending on your oven, on the size of your meatballs, and on the pan that you bake them in. You'll know they're done when the rice inside a meatball is tender (it may be crispy on the outside). Add extra water, tomato soup, or tomato sauce to the dish if you need to extend the baking time.
