Preheat Your Oven: Start by preheating your oven to 400°F (200°C) so it’s nice and hot when your meatballs are ready to go in.
Mix Ingredients: In a large mixing bowl, combine the ground beef, breadcrumbs, Parmesan cheese, parsley, egg, garlic, oregano, along with salt and pepper. Mix gently but thoroughly to avoid overworking the meat.
Shape the Meatballs: Using your hands, shape the mixture into meatballs about 1 inch in diameter. This size will ensure even cooking.
Place on Baking Sheet: Line a baking sheet with parchment paper and place the meatballs evenly spaced apart.
Bake: Bake in the preheated oven for 20-25 minutes or until the meatballs are golden brown and cooked through.
Serve: Drizzle with warm marinara sauce or serve as desired. Enjoy!
