This sounds delicious, I have actually baked my meatballs in the past, but I end up with the fat surrounding it, which is why I rarely do it. (dineanddish.net)
Bake meatballs for 30 - 35 min or until browned on top and cooked through (165 degrees). (witandvinegar.com)
Transfer the baking sheet to the oven and bake the meatballs until firm to the touch and no longer pink in the center, 16 to 20 minutes. (williams-sonoma.com)
