Heat the oven to 425°F and line a sheet pan with parchment.
Mix the beef, egg, breadcrumbs, half the parmesan, minced garlic, salt and pepper. Roll into 16-20 meatballs.
Place meatballs on one side of the pan. Toss broccoli florets with oil and salt on the other side. Roast 15 minutes.
Warm the marinara in the microwave. Spoon some over the meatballs, top them with mozzarella and the rest of the parmesan, and bake 5 minutes until melty.
Serve meatballs with the broccoli and extra sauce for dipping.
