Preheat your oven to 400°F (200°C) if you’re baking, or heat a skillet over medium heat for pan-frying. Either way, we’re starting strong.
In a bowl, combine breadcrumbs and milk. Let them soak for a couple minutes so the meat stays juicy.
Add ground beef, egg, garlic, Parmesan (if using), oregano, salt, and pepper. Mix gently—don’t squeeze the life out of it; we’re making tender meatballs, not hockey pucks.
Shape the mixture into about 1.5-inch balls. If you’re fancy, use a small scoop to keep them uniform.
For pan-frying: heat oil in a skillet. Brown the meatballs on all sides, about 2–3 minutes per side. They don’t have to be perfect—quirkiness is charming.
Simmer: add marinara sauce, cover, and cook 10–15 minutes until cooked through. If baking: place meatballs on a tray, bake 12–15 minutes, then simmer in sauce for a few minutes to finish.
Serve hot, with sauce ladled over and a sprinkle of parsley if you’re feeling fancy.
