Cut potatoes smaller than the kielbasa (¾-inch potato cubes, ½-inch sausage coins). Potatoes take longer to cook — sizing them this way lets everything finish together.
Single layer only. Overcrowding steams instead of crisps. Cook in two batches if your basket is small.
Shake the basket every 5 minutes for even browning on all sides.
Pat potatoes dry before tossing with oil — drier potatoes = crispier potatoes.
Yukon Gold or red potatoes hold their shape best. Russets work but get fluffier inside.
Pre-cooked kielbasa is standard. If using fresh raw Polish sausage, increase cook time to 18 minutes and check for 160°F internal temp.
Go easy on the salt. Kielbasa is naturally salty — taste before adding the full amount.
For extra crispy potatoes, soak diced potatoes in cold water for 15 minutes, then drain and pat dry before seasoning.
Reheat in the air fryer at 350°F for 4–6 minutes to bring back the crispy texture. Skip the microwave.
Storage: Refrigerate in an airtight container up to 4 days, or freeze up to 2 months.
