Instructions

• In a medium bowl, combine 1 pound lean ground beef, 1/2 small onion (diced), 3 cloves garlic (minced), 1/4 cup grated Parmesan cheese, 1/2 cup Italian breadcrumbs, 2 Tablespoons chopped parsley, 1/2 teaspoon salt, 1/4 teaspoon pepper, 1 large egg, and 1/2 cup milk.
• Mix gently with your hands or a spoon until the ingredients are just combined; avoid overmixing.
• Shape the mixture into 2-inch meatballs, rolling between your palms to form even balls.
• Preheat the air fryer to 400°F (if your model requires preheating). Place the meatballs in the air fryer basket in a single layer with space between each meatball so air can circulate.
• Cook at 400°F for 10–12 minutes, turning the meatballs once halfway through the cooking time for even browning.
• Check that meatballs are cooked through (no pink in the center). Remove from the air fryer and let rest a minute or two before serving.
