Ingredient prep:

Wash potatoes thoroughly and dry with kitchen paper.

Remove sausage casings and slice sausages into 0.5 cm thick rounds (not too thin — thin slices dry out and lose juiciness).

If butter is solid, melt it in a small bowl over a hot water bath (water temperature should not exceed 60°C to prevent butter browning). Set the butter aside until warm.

(1) Cut the potato pocket

Trim about 0.3 cm from the potato bottom so each potato can stand flat in the fryer basket.

From the top, cut a V-shaped pocket into each potato — depth about 2/3 of the potato height, width about 3–4 cm. Do not cut through the bottom; preserve the base so the potato holds the filling.

(2) Season & initial bake

Place the potatoes upright in the air fryer basket (cut pocket facing up). Keep space between potatoes — don't stack.

Use a silicone brush to evenly apply melted butter over the potato surface and inside the cut pocket (brush every crevice so flavor penetrates).

Evenly sprinkle salt and freshly ground black pepper over the exterior and inside the pocket.

Air-fry at 200°C for 15 minutes to pre-cook until potatoes become tender. Test with chopsticks or a skewer: when you can easily pierce the potato side, the initial bake is complete.

(1) Assemble

Fill each potato pocket with 6–8 sausage slices (adjust for potato size). Arrange to nearly fill the pocket but avoid overflowing; leave tiny gaps between sausage slices to allow cheese to settle.

Completely cover the sausage with shredded cheese, ensuring a full cheese layer that will melt into a cohesive, stretchy top.

(2) Second bake

Return the assembled potatoes to the air fryer basket.

Air-fry at 200°C for 6 minutes — this melts the cheese to full stretchiness and heats the sausages until juicy. Do not exceed 6 minutes (longer time risks cheese hardening and drying the potato).

Remove hot potatoes, immediately sprinkle 2g parsley flakes for aroma (sprinkle while hot so parsley releases fragrance).

Let the filled potatoes rest 1–2 minutes to avoid burns, then serve. Optionally offer ketchup or honey-mustard on the side.
