Short Answer:

To roast bell peppers in an air fryer, wash and cut them into halves or quarters, removing seeds and stems. Lightly coat with oil and season with salt or preferred herbs.

Place the peppers in a single layer in the air fryer basket and cook at 180–200°C (350–400°F) for 10–15 minutes, shaking or turning halfway through. This produces tender, slightly charred, and flavorful bell peppers perfect for salads, sandwiches, or side dishes.

Detailed Explanation:

Roasting Bell Peppers in an Air Fryer

Air frying bell peppers is a quick and convenient method that enhances their natural sweetness while adding a slightly charred flavor. Start by washing the peppers thoroughly to remove dirt or residues. Cut them into uniform halves or quarters, and remove seeds and stems to ensure even cooking. Uniform sizes prevent some pieces from overcooking while others remain undercooked.

Coating and Seasoning
Lightly coat the bell pepper pieces with oil to promote browning and prevent sticking. Season with salt, black pepper, garlic powder, or herbs such as oregano or thyme. Light oil coating helps the peppers develop a roasted flavor without becoming greasy. Additional spices or seasoning blends can be added to suit personal taste preferences.

Air Fryer Preparation
Arrange the bell peppers in a single layer in the air fryer basket. Avoid overcrowding, as this reduces airflow and can prevent even roasting. Preheating the air fryer for 2–3 minutes ensures consistent heat and improves the roasting process. Shaking or turning the peppers halfway through cooking promotes uniform char and caramelization on all sides.

Temperature and Cooking Time
Set the air fryer to 180–200°C (350–400°F) and cook for 10–15 minutes. Smaller pieces may cook faster, so monitor the peppers during the last few minutes to prevent burning. The peppers should have slightly charred edges while remaining tender and juicy inside. Adjust the time slightly based on personal preference for softness and caramelization.

Texture and Flavor
Properly air-fried bell peppers have tender, flavorful flesh with a slightly smoky and charred taste. The high heat of the air fryer enhances natural sugars, making the peppers sweeter and more aromatic. Light seasoning further complements the flavor while maintaining a healthy preparation method.

Serving Suggestions
Roasted bell peppers can be served as a side dish, added to sandwiches, tossed into salads, or blended into sauces. They pair well with grains, meats, and other vegetables. A drizzle of balsamic vinegar or a sprinkle of fresh herbs after cooking can enhance flavor and presentation.

Conclusion

Roasting bell peppers in an air fryer involves washing, cutting, oiling, and seasoning, followed by cooking at 180–200°C for 10–15 minutes in a single layer. Shaking or turning halfway ensures even caramelization and tender, flavorful results. Air-fried bell peppers are sweet, slightly charred, versatile, and perfect for a variety of dishes.
