- 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!
