1/2cup finely chopped onion (or half a medium yellow onion)
1/2cup Italian breadcrumbs
1 tbsp kosher salt
1 tsp pepper
6cups marinara
Instructions
Preheat oven to 400 degrees. In a large mixing bowl, add the egg and milk and whisk until combined.
Add the Parmesan, parsley, garlic, onion, salt, and pepper and stir to combine.
Add the meat and breadcrumbs and gently mix until combined.
Use an ice cream scoop to scoop meatballs onto a parchment-lined baking sheet, making sure they don’t touch. Bake for 10 minutes or until browned on top.
Meanwhile, place the marinara in a large pot and set it to medium-low.
Add the meatballs and simmer for half an hour before serving with spaghetti, Parmesan, and chopped parsley or fresh basil.
