These recipes are specific to each model number. Even within the same brand, do not apply settings intended for one model to another.

Initial Heating Settings

First HeatingAir Oven180°C / 10min

After cooking, check the doneness requirements in the main instructions.

This is the cooking time for the first round. Please refer to the instructions for preheating. You’ll need to check for doneness and cook further as needed.

The boiling time specified on the package, the preparation of the white sauce, and the cooling-off period are not included in the 10-minute setting for RAO-3. The time required for each step and the total time until completion have not been measured.

Check Before Cooking
  • The test portion weighs 60g of dry macaroni. When combined with the sauce and spread out in the pot, the depth should be 30mm or less, and the amount should be approximately half the container’s capacity. If it doesn’t fit, divide it into portions and avoid piling it high.
  • The quantities, thickness, and initial conditions are based on my own experimental parameters; the optimal amounts and results on an actual appliance have not been verified. Start without preheating.
  • Place 1 inner pot correctly and spread the ingredients evenly to a depth of 30mm or less. Divide any excess that does not fit. Since the interior will be warm for subsequent batches, the same results may not be guaranteed.
  • Make sure that ingredients and containers do not exceed the MAX line and do not block the steam vents or hot air vents. Do not line the basket with paper or foil.
  • The initial cooking time setting does not represent the total time required to complete the dish. If the cooking process is paused for approximately 10 minutes, check the unit’s display and the remaining time before resuming.
  • Keep continuous use—including additional heating and cooking in batches—to less than 180 minutes. When using the appliance continuously, follow the instruction manual and allow the unit to cool completely before resuming use.

    Boil the macaroni in a separate pot

    Bring 1L of water to a boil in a pot and add 60g of macaroni. Cook according to the instructions on the package, then check to make sure there is no hard core in the center before draining in a colander. Discard the cooking water.

    Making White Sauce

    Thinly slice 40g of onion. Melt 10g of butter in a frying pan and sauté the onion over low-to-medium heat until softened. Add 12g of cake flour and stir until there are no lumps. Add 160ml of milk in 3 batches, mixing well after each addition. Add 1.5g of salt and 0.2g of pepper, and heat until the mixture simmers, thickens, and no raw flour remains in the paste.

    Spread out in the pot

    Mix the boiled macaroni into the sauce. Lightly coat the inner pot with the remaining 2g of butter, spread the filling—once it has cooled slightly—to a depth of no more than 30mm, and top with 35g of cheese. If you interrupt the preparation process, do not leave the ingredients at room temperature; refrigerate them instead, and be sure to distinguish this from the room-temperature starting conditions described here.

    Brown the surface

    Fit the inner rack in the correct orientation, and orient the inner pot’s handle front to back relative to the front of the basket. Place the pot in the center or toward the front of the inner rack, leaving the rear steam vent clear. Start Air Oven at 180℃ for 10 minutes. Pause after 5 minutes to check the color of the cheese; if it starts to burn, stop early.

    Check to see if it’s warm all the way through

    Check that the cheese has melted and that the sauce exposed by opening the center with a clean spoon is hot. If more heating is needed, set Air Oven to 180℃ for 5 minutes, then stop manually after 2〜3 minutes to check. Remove the pot with oven mitts and place it on a trivet. The sauce is very hot, so let it cool to an edible temperature before portioning it out.

Check the results

Make sure the macaroni and sauce have been thoroughly heated in a separate pot, and after baking, check that the center is hot and the cheese has melted. This method cannot be used if you are adding raw shrimp or meat.

If you get stuck along the way

The sauce forms lumps

Add the milk a little at a time, mixing until smooth after each addition.

Only the surface turns dark

Check the surface partway through the first try, and don’t extend the cooking time until it burns. Next time, make sure the ingredients are all the same depth.

How the Recipes Were Created and Sources Consulted

These are original recipes created using AI on Crisp. They are not listed as official manufacturer recipes or recipes that have been verified using actual devices.

Standards verified in official documents
The official method calls for 100g of dry macaroni (the type that takes 9 minutes to boil), cooked in the inner pot using the "Hi Steam" setting at 160℃ for 26〜30 minutes.
Independently designed details and unverified points
This page describes a method where 60g of the ingredient is boiled in a separate pot, combined with a homemade sauce that contains no meat or fish, and then browned on the surface in an Air Oven. This is an original prototype created by adjusting the ingredients, prep steps, cooking mode, initial cooking time (10 minutes), and depth; it does not reuse the official recipe’s conditions that require no separate boiling.

The manual states that a short press of TIME changes the setting by 5 minutes, while its cooking references also include times such as 18 minutes. Since actual device increments are unverified, this page uses initial settings in 5-minute increments and distinguishes them from elapsed checking times. Omitting alcohol is an independent prototype policy.
