Step 1

Preheat the oven to 400°F.

Step 2

Chop red onion, garlic, and parsley. Mix the ground meat, egg, breadcrumbs, red onion, garlic, and parsley. Shape into balls (around the size of a golf ball).

Step 3

Heat olive oil on a cast-iron pan. Add meatballs and leave them on until they get crispy and brown on the outside. They do not have to be fully-cooked as they will bake in the oven.

Step 4

For the marinara sauce, add onions to the pot. Once translucent, add tomatoes.

Step 5

Add tomato paste and simmer for 10 minutes. Then, add Italian seasoning.

Step 6

Transfer the sauce into the cast-iron pan. Nestle the meatballs in the sauce and sprinkle the cheese over the meatballs.

Step 7

Bake for twenty minutes.

Step 8

Sprinkle with chopped parsley if desired.

Step 9

Enjoy!
