Stir the panko and milk together in a large bowl; let stand 5 minutes until pasty.
Add the beef, pork, egg, Parmesan, garlic, parsley, Italian seasoning, salt, and pepper. Mix with your hands just until combined — do not overwork.
Roll into 1¼-inch meatballs, about 1½ tablespoons each. You'll get roughly 20.
Place the crisper plate in the 4-quart glass container. Arrange meatballs in a single layer with space between them, working in two batches if needed. Mist lightly with olive oil.
Attach the PowerPod and cook on Air Crisp at 380°F for 12 minutes, shaking the container at the 6-minute mark.
Check for an internal temperature of 160°F. Add 2 minutes if needed. For extra crust, finish on Max Crisp at 400°F for 2 minutes.
Rest 5 minutes before serving.
