Illustrations are AI-generated images. They are not photographs of actual cooking or evidence that the food has been cooked through.
After 5 minutes, press START/STOP to stop the cycle and place the basket on a trivet. Flip all 4 pieces at once, swapping their front and back sides. Remove any pieces where the batter has started to burn; do not resume cooking them. Remove any shrimp that are hot all the way through and have dry batter to a clean plate; return only those that are cool in the center and not burnt to the inner basket, then press START/STOP to resume the remaining time. If you notice smoke, an unusual odor, or an error message, stop immediately, discontinue use, and follow the instructions in the user manual.
Instructions for preheating, mid-cooking checks, and how to check for doneness are included in the preparation instructions.
Reheat the shrimp tempura—which has been thoroughly cooked through after purchase or preparation—from a chilled state according to the product label. This is not the traditional tempura method of coating raw shrimp in batter and frying it.
Check Before Cooking
Fit the inner rack in the correct orientation while the appliance is cold. Use Air Oven without preheating. Do not switch to a mode that uses water.
Use 4 pieces of pre-cooked shrimp tempura (a total of 120g) that have been heated all the way through after purchase or cooking, with a maximum batter-covered body thickness of 18mm or less. Store in the refrigerator according to the product label; use only items that are within their use-by date and free of sauce or moisture. Do not substitute with raw shrimp, uncooked tempura batter, frozen products, mixed platters, or kakiage.
Do not use any additional oil. Do not line the air fryer with aluminum foil, parchment paper, or a heat-resistant container; place the food directly on the specified inner basket. Do not use items with batter that has peeled off or is wet.
Arrange the shrimp tempura in a single layer so they do not overlap or touch each other. Ensure the tails are not close to the heating element and that the ventilation holes and the “MAX” line are not blocked. If 4 pieces do not fit, do not start heating; instead, check the official instructions for the same model to confirm the correct quantity and arrangement. Do not proceed if you cannot confirm this. Do not estimate cooking times proportionally based on the number of servings or the appliance’s capacity.
Do not leave the area while cooking, and do not block the air intake or exhaust vents. Do not use the appliance if batter residue has fallen inside. If you notice smoke, a burning smell, or any other abnormalities, stop heating and discontinue use in accordance with the instruction manual.
Limit continuous use to less than 180 minutes, and wait until the unit has cooled completely before cooking again.
Instructions
01
Check the refrigeration status and quantity
Check the storage instructions and use-by date on the product label. Weigh 4 refrigerated, fully cooked shrimp tempura pieces and confirm that they total 120g and that each body is no more than 18mm thick including the coating. Do not use pieces with sauce, moisture, or substantially detached coating. Do not add oil.
Weigh 4 refrigerated, pre-cooked shrimp tempura sticks and check the weight and thickness listed in the ingredients section.Discuss these instructions
02
Prepare the main unit
Attach the inner basket to the cooled unit, ensuring it is oriented correctly. Do not preheat; use the “Air Oven” setting. Do not add water to the water tank, and do not switch to a mode that uses water.
Arrange them in a single layer without using a sheet
Do not use aluminum foil, parchment paper, or heat-resistant containers. Place 4 shrimp tempura directly onto the designated inner rack. Do not stack them; leave enough space so they do not touch each other, and keep the tails away from the heating element. Make sure not to block the ventilation holes or the “MAX” line.

04
Reheat in the Air Oven
Set the Air Oven to 160℃ for 10 minutes, then press START/STOP to begin. After 5 minutes, press START/STOP to stop the cycle, place the basket on a trivet, flip the 4 pieces over, and switch their front and back positions. For mid-cooking checks, follow the guidelines in the “Cooking Stage” section for “Done,” “Not Done,” or “Abnormal”; only resume the remaining time for items that need to be returned to the basket.
Once the set cooking time has elapsed, crack open the 2 thickest pieces of battered shrimp on a clean plate. Serve only if the shrimp is hot all the way through with no cold spots, the surface of the batter is dry, and there are no burnt or hard spots. If the center is still cold, remove the entire batch and proceed to the final check. Do not consider the dish finished based on surface color alone.

06
Serve without a lid
Transfer the shrimp tempura that meets the readiness criteria to a clean plate. Do not cover with a lid or plastic wrap to prevent the batter from becoming soggy, and eat while still warm. If using tempura dipping sauce, serve it in a separate bowl after reheating the shrimp tempura.
If the food does not meet the completion criteria, stop reheating and do not eat it. Check the actual heating time, the quantity and thickness of the food, how long it has been out of the refrigerator, and the condition of the center and the coating. Do not add time based on guesswork unless you can confirm, using the official instructions or product labeling for the same model number, how to adapt the method to your specific conditions.
Break open the 2 thickest of the 4 shrimp tempura pieces, including their coating, on a clean plate. Check that the shrimp is hot all the way to the center with no cold spots, and that the surface of the coating is dry with no burnt or hard areas. Do not eat any piece with a cold center; proceed to the final check.
Can I use it on raw shrimp or tempura before frying?
This method cannot be used. It is intended only for 4 pieces of shrimp tempura that have been thoroughly cooked through and then refrigerated after purchase or preparation. Raw shrimp, uncooked batter, and frozen products require different cooking instructions.
Is it okay to line the bottom with aluminum foil or parchment paper?
Do not line the pan for this recipe. Covering the bottom or ventilation holes will hinder the circulation of hot air, resulting in uneven drying and heating of the batter. Do not place the food in a heat-resistant container; instead, arrange it in a single layer directly on the specified inner mesh basket.
Will adding more oil make the batter crispier?
Do not add any additional oil. Reheat the food using the residual oil remaining in the batter from the initial frying; do not use a pool of oil or cooking spray. Do not use this method if the food is covered in sauce or water.
Can I heat up the vegetable tempura and kakiage at the same time?
Do not reheat them together. Since the thickness, moisture content, and amount of batter vary, we’ll limit this to 4 shrimp tempura for now. We will not adjust the quantity or time for mixed platters, kakiage, chikuwa tempura, etc.
Can I put it in right after taking it out of the fridge?
Refrigerate the product according to the package instructions, then check the quantity and the condition of the batter before adding it. Do not use products that have passed their expiration date, have been left at room temperature for a long time, or have been frozen.

Standards verified in official documents
Guidance for reheating store-bought tempura and other fried prepared foods in Air Oven at 160℃ for 10 minutes.
Independently designed details and unverified points
The documentation does not specify the quantity or thickness of the ingredients. The conditions used—4 refrigerated, pre-cooked shrimp tempura sticks (total weight 120g, maximum thickness 18mm), no additional oil, arranged in a single layer, and flipping and checking the center at the 5-minute mark—are Crisp’s proprietary test conditions.
The initial setting is in 5-minute increments. Check the progress based on the elapsed time since heating began; do not use the check time as the unit’s set time.
