Preheat the Oven: Set the oven to 375°F (190°C) so it's ready for baking.
Prepare the Mixture: In a large bowl, combine the ground beef, breadcrumbs, parmesan cheese, egg, minced garlic, Italian seasoning, salt, and pepper. Mix everything together until well combined.
Form the Bites: Using your hands, shape the mixture into small, bite-sized balls (about 1 inch in diameter).
Arrange on a Baking Sheet: Place the formed bites on a baking sheet lined with parchment paper, ensuring they’re spaced out to allow even cooking.
Bake: Pop them in the oven and bake for about 20-25 minutes, or until they're golden brown and cooked through.
Serve: Remove from the oven and serve warm with marinara sauce for dipping. If you opt for additional toppings, sprinkle them on right before serving!
