1Place the ground meat in a large bowl. Add the egg, salt, pepper and sweet paprika (if using).
2Finely chop the onion (or green onions), garlic (or green garlic) and parsley. Add them to the meat.
3Add the dried thyme (if using) and the bread slice soaked in water or milk and well squeezed – this step makes the meatballs fluffy and tender.
4Knead the mixture with your hands until you get a homogeneous and slightly sticky paste. Cover with plastic wrap or a plate and let it rest for 15 minutes.
5Divide the mixture into 12 medium-large meatballs (you can use an ice cream scoop for uniformity). Shape them with palms lightly greased with oil.
6Preheat the air fryer to 205°C (400°F) for 5 minutes. Place the meatballs in the basket, leaving space between them for hot air circulation.
7Cook at 180°C (350°F) for 15 minutes, then at 170°C (340°F) for another 10 minutes to brown. Check the doneness halfway through.
8For oven: preheat to 180-190°C (350-375°F) and bake on a tray lined with parchment paper for 25-30 minutes, turning halfway.
9Serve hot with your favorite side (mashed potatoes, salad, pickles).
