Ingredients

• 1 Costco frozen lasagna (single-serve or cut portion from family-size tray)

• Optional:

  • Aluminum foil (to prevent over-browning)

  • Parmesan, parsley, or crushed red pepper for garnish

Instructions

Step 1: Preheat the Air Fryer

Set the air fryer to 360°F (182°C) and preheat for 3–4 minutes.

Step 2: Prepare the Lasagna

Remove all external packaging. Keep lasagna in the foil tray or oven-safe container. Do NOT use any plastic film in the air fryer—remove it completely.

Step 3: Air Fry to Perfection

Place the tray in the air fryer basket or oven.

• Cook at 360°F for 25–30 minutes

• Cover loosely with foil for the first 15–20 minutes to avoid cheese burning

• Remove foil in final 5–10 minutes to let the top brown and bubble

Step 4: Check for Doneness

Lasagna should be bubbling, hot in the center, and reach an internal temperature of 165°F (74°C).

Step 5: Rest and Serve

Let rest for 3–5 minutes to allow layers to set, then serve hot with optional toppings.

Pro Tips for the Best Results

Use Foil to Avoid Burned Cheese

Covering the lasagna for the first part of cooking helps prevent over-browning.

Place Tray on a Rack or Liner (Optional)

Makes cleanup easier and promotes even airflow under the tray.

Cut Family-Size Portions Before Cooking

If using a large tray, cut and cook individual servings for best results.

Check Temperature Near the Center

The middle should be fully hot and not cold or partially frozen.
