Ingredients
1 or more frozen stuffed peppers from Costco
Optional toppings:
Shredded cheese, parsley, red pepper flakes
Sour cream, hot sauce, or marinara for serving
Instructions
Step 1: Preheat the Air Fryer
Set your air fryer to 360°F (182°C) and preheat for 3–4 minutes.
Step 2: Prepare the Stuffed Peppers
Remove any plastic film or outer packaging. If the peppers are in a tray, transfer to a heat-safe dish or wrap in foil for easier air frying.
Step 3: Air Fry to Perfection
Cook at 360°F for 15–18 minutes, depending on the size
If the tops start to brown too quickly, loosely cover with foil during the last 5 minutes
Internal temperature should reach 165°F (74°C)—check by inserting a thermometer into the center of the filling
Step 4: Let Rest & Serve
Allow to rest for 2–3 minutes, then top with herbs, cheese, or your favorite finishing touches.
Pro Tips for the Best Results
Cover with Foil if Browning Too Fast
To avoid burnt cheese or over-toasted tops, tent loosely with foil mid-way.
Use a Heat-Safe Dish or Foil Packet
Helps hold in juices and prevent leaks into the basket.
Add Cheese Midway for a Melty Finish
Sprinkle mozzarella or parmesan in the last 3–4 minutes of cooking.
Cook in Batches if Needed
Don’t overcrowd—peppers need airflow around them to heat evenly.
