Preheat the Oven: Begin by preheating your oven to 400°F (200°C). This ensures the meatballs will cook evenly and develop a lovely golden crust.
Mix the Ingredients: In a large bowl, combine the ground beef, breadcrumbs, Parmesan, parsley, egg, minced garlic, Italian seasoning, salt, and pepper. Mix gently using your hands until just combined—no need to overdo it!
Form the Meatballs: Scoop out small portions of the mixture (about 1 inch in diameter) and roll them into smooth balls.
Place on Baking Sheet: Arrange the meatballs on a lined baking sheet, leaving a bit of space between them to allow for even cooking.
Bake: Pop them in the oven for about 20 minutes, or until they are browned and cooked through. You can check by cutting one in half—no pink should remain!
Serve: Warm your marinara sauce on the stove and serve the meatballs over your favorite pasta or in a sub. Enjoy!
