Cut the pumpkin and potatoes into cubes and cook with the 100% steam mode for 30 minutes. Once cooked, blend briefly with the hand blender, add the breadcrumbs, chopped rosemary, pecorino cheese, and egg. Mix well.

Use a spoon to make meatballs of the same size. Insert a cube of scamorza cheese in the center of the dough and form a ball. Roll the patties in breadcrumbs and place on the air-fry tray.

Cook in the countertop combi steam oven and choose the air-fry mode at a temperature of 220°C for 15 minutes.

Once cooked, serve immediately.
