Cook until flippedTimer DialNo temperature setting / 20min
Once the 20 minutes are up, check that the dial has stopped at 0, and use tongs to flip only those pieces 1 time that do not have cracked coating, leaking filling, or signs of burning. Do not return any pieces that are cracked or have started to burn.
Cooking After Turning OverTimer DialNo temperature setting / 5min
When the 5 minutes are up, make sure the dial stops at 0, then crack open 1 to check the center. If it does not meet the criteria for being done, do not add more time; proceed to the final check step.
Instructions for preheating, mid-cooking checks, and how to check for doneness are included in the preparation instructions.
Keep frozen until just before cooking. Do not thaw, cut into portions or heat separately.
Check Before Cooking
Use only commercially available frozen potato croquettes that are pre-cooked and pre-fried, and whose packaging indicates they can be reheated in an oven or air fryer. Use 2 croquettes: 1 piece weighs 65g and is no more than 30mm thick, for a total of 130g. Use them frozen; do not substitute uncooked products, cream croquettes or products whose label does not confirm they are pre-cooked.
Attach the inner basket to the cold unit in the correct orientation. Do not preheat or set the temperature.
Stay beside the air fryer during cooking and keep the intake and exhaust vents clear. If there is smoke, a burning smell or anything abnormal, stop heating and discontinue use according to the manual.
Arrange 2 pieces in a single layer with gaps. Before heating, check that they stay below the MAX line and do not block the ventilation holes. If they do not fit, do not start; check the official instructions for the same model for a method matching the amount, number of pieces, and maximum thickness. Do not divide the food into batches while keeping the original cooking time, or scale the time using weight or capacity ratios.
Do not use additional containers, aluminum foil, or parchment paper. Lightly coat both sides of the 2 pieces with 3g of rice bran oil, taking care not to create pools of oil.
Instructions
01
Check product labels and quantities/thicknesses
Check the product label to confirm that these are pre-cooked, oil-fried potato croquettes and that they can be reheated in an oven or air fryer. Verify that 2 frozen croquettes weigh a total of 130g, that 1 piece weighs 65g, and that the maximum thickness including the breading is 30mm. Brush off any large frost crystals. Lightly brush 3g of rice bran oil onto both sides of the 2 croquettes without leaving pools of oil. Do not proceed with products that have different specifications.
Verify that 2 frozen pieces total 130g, that 1 piece weighs 65g, and that the maximum thickness is 30mm.Discuss these instructions

Prepare the main unit
Attach the inner basket to the cold unit in the correct orientation. Do not preheat or set the temperature.
Place 2 pieces in a single layer, leaving space between them
Place 2 croquettes on the inner rack or crisper plate in a single layer, leaving space between them. Do not use paper, foil or containers, and do not block the ventilation holes.

04
Cook and flip exactly 1 time partway through
Turn the timer dial to 20 minutes to start. After 20 minutes, confirm that the dial has stopped at 0, then place the basket on a trivet. Using tongs, flip items only 1 time—only those without cracks in the coating, leaks, or signs of burning. Do not return any items with cracks or those that have started to burn to the basket. Set the timer to at least 10 minutes, then reset it to 5 minutes to begin the second cooking cycle after flipping. For checks during cooking, follow the guidelines in the “Cooking Stages” section for “Complete,” “Not Complete,” and “Abnormal.”
When the set time is up, stop cooking, transfer 1 croquette to a clean plate and split it open with a fork. Check that it is hot all the way to the center, with no frozen, cold or hard spots, and that the potato filling is smooth and evenly heated. Do not judge doneness by the color of the coating alone; if the criteria are not met, do not eat either of the 2 croquettes and proceed to the final check.

Be careful not to burn yourself when plating.
Once the recipe is done, check that the rest is hot all the way through and transfer it to a clean plate. Since the contents and steam are hot, do not eat it immediately after cutting it open; wait until it has cooled to a safe eating temperature.
If the food does not meet the doneness criteria, stop heating without adding time, and do not eat either of the 2 pieces. Check the product label or official instructions for the same model for a method matching the actual number of pieces, weight, thickness, and frozen state. If no matching method is available, do not repeat heating based on guesswork.
Cut 1 open and check that it is hot all the way to the center, with no frozen or hard spots, and that the inside of the potato is evenly heated. Do not judge based on the color of the coating alone. If these conditions are not met, do not eat it; proceed to the final verification step.
Do not use this setting. It applies only to pre-cooked, pre-fried potato croquettes whose product label confirms they can be reheated in an oven or air fryer. Do not use it for uncooked products, products that specify frying in oil only, cream croquettes, or products where 1 piece weighs more than 65g or exceeds a maximum thickness of 30mm.
Should I thaw it before adding it?
Use the product while still frozen. Keep it in the freezer until just before cooking, and simply brush off any large frost crystals from the surface. Do not use these settings for thawed or refrozen products.
What should I do if the batter cracks or the filling comes out?
Remove the item from the air fryer, and if any oil or contents appear likely to come into contact with the heating element or ventilation openings, stop heating. Check the rest of the food for cracks or burning; if you notice any unusual odors, smoke, or error indicators, stop use and follow the instructions in the user manual.
What if the product labeling or quantities differ?
This product is outside the scope of this recipe. Do not ignore the product instructions by merely matching the cooking time, or scale the time in proportion to the number of pieces or weight. Check the product label for a cooking method appropriate for the product you have. If no matching method is available, do not cook it using these settings.
How the Recipes Were Created and Sources Consulted
Standards verified in official documents
The RAO-2 instruction manual includes an example of heating 2 frozen croquettes for 15〜20 minutes, then flipping them over and cooking for another 5 minutes to ensure the oil is thoroughly absorbed on both sides. There are no instructions for setting the temperature.
Independently designed details and unverified points
Adjust the number of pieces and starting condition according to the user manual; the upper limits for Crisp. are 65g for 1 piece and a maximum thickness of 30mm. For the “15〜20 minutes” range in the table, stop the cooking once at the upper limit of 20 minutes, flip the food, cook it in a separate stage for 5 minutes within the timer limit, then check the center after cooking ends. Product weight and doneness have not been verified.
