Pepperoni, the spicy, smoky, and slightly tangy cured sausage, is beloved for its robust flavor and crisp texture. Traditionally found atop pizzas or tucked inside sandwiches, pepperoni can also shine as a standalone snack, especially when prepared in an air fryer. The magic of the air fryer lies in its ability to circulate hot air around the food, producing a crisp exterior without the need for excessive oil, making it a healthier and faster alternative to oven-baking or pan-frying. Cooking pepperoni in an air fryer is a straightforward process, but it requires careful attention to temperature, timing, and technique to ensure the slices reach the perfect balance of crispness and flavor. In this guide, we will delve deeply into every aspect of air-frying pepperoni, from selecting the ideal temperature to troubleshooting potential issues, so you can enjoy this classic snack with ease and precision.
Temperature control is crucial when cooking pepperoni in an air fryer because this sausage is thinly sliced and high in fat. Too low a temperature may result in limp, chewy slices, while too high a temperature can burn them in moments. The optimal temperature range is 350°F to 375°F (175°C to 190°C).
At this range, the air fryer gently renders the fat from the pepperoni, allowing the edges to crisp while preserving the deep, smoky flavor. Cooking below 350°F might leave the slices oily and undercooked, whereas exceeding 375°F risks turning them brittle or even charred, which can overpower the natural seasoning and spices in the meat.
For extra precision, consider using the lower end of the spectrum if your slices are thick or if you prefer a chewier texture, and the higher end if you desire maximum crispiness or if you are preparing smaller, thinner slices.

Cooking time is closely linked to temperature and slice thickness. For standard pre-sliced pepperoni:
It is important to monitor the slices during cooking because the high fat content can cause them to cook faster than anticipated. Overcooking can quickly turn the pepperoni brittle or overly oily, while undercooking may leave them soft and greasy. A good practice is to shake or move the slices halfway through the cooking process to ensure even crisping on all sides.
Pepperoni is done when the slices are slightly curled at the edges, have a golden-brown hue, and appear firm to the touch. Key indicators include:
Avoid relying solely on time, as air fryer performance can vary between models. Visual and tactile checks are the most reliable indicators of doneness.
To prepare air-fried pepperoni, you only need:
That’s it. Pepperoni’s own fat content usually eliminates the need for added oil, making this a simple and convenient snack.
These steps will yield perfectly crisp, flavorful pepperoni that can be enjoyed on its own, on pizza, or as a snack topping.
Altering the temperature can drastically affect the outcome:
If experimenting, reduce the cooking time when increasing temperature and increase the time when lowering temperature. Constant monitoring is key.
Adjusting cooking time without modifying temperature can also impact results:
Start with the recommended times and make minor adjustments in 30-second increments to match your desired crispness.
Even experienced cooks can encounter issues:
Yes, both fresh and pre-sliced pepperoni can be cooked in an air fryer. Pre-sliced pepperoni usually cooks faster and becomes crispy within 4-6 minutes at 375°F, while fresh, thicker pepperoni may require slightly longer cooking time and should be monitored closely to avoid burning.
Preheating is recommended for even cooking. Set the air fryer to the desired temperature, usually 375°F, and preheat for 2-3 minutes. This ensures the pepperoni crisps evenly without releasing excess oil unevenly.
No additional oil is typically necessary because pepperoni contains enough natural fat that renders during cooking. Adding oil may make the slices overly greasy. However, a light spray can be used if you want extra crispness.
To prevent sticking, line the basket with parchment paper or a perforated silicone mat. Make sure the slices are arranged in a single layer with small gaps to allow airflow. Avoid overlapping slices, as this can cause uneven cooking.
The optimal temperature is 375°F (190°C). Thin slices usually take 4-6 minutes, while thicker slices may require 6-8 minutes. Check the pepperoni halfway through cooking and shake or rearrange the slices for uniform crisping.
Absolutely. Air-fried pepperoni becomes crispy and works perfectly as a topping for pizza, salads, sandwiches, or pasta dishes. The crispiness enhances texture and flavor compared to uncooked pepperoni.
Allow the pepperoni to cool completely, then store it in an airtight container in the refrigerator for up to 3-4 days. To maintain crispiness, reheat in the air fryer for 1-2 minutes rather than using a microwave, which can make it soggy.
