Poblano peppers are a cornerstone of Mexican cuisine, celebrated for their mild heat, rich flavor, and versatility in dishes like chiles rellenos, salsas, and roasted sauces. Traditionally roasted over an open flame or in an oven, poblano peppers develop a smoky, slightly charred exterior while softening on the inside, enhancing their natural sweetness. However, with modern kitchen tools like the air fryer, achieving this perfectly roasted texture is faster, cleaner, and more convenient than ever. Air frying poblano peppers allows for an even roast with minimal oil, making it a healthier option without compromising flavor. This guide will walk you through every step of the process, ensuring you achieve perfectly roasted poblano peppers every time.
Temperature control is critical when roasting poblano peppers in an air fryer. Too low, and the peppers will remain undercooked and lack that signature blistered texture; too high, and they risk burning before the flesh softens. The optimal temperature range is 380°F to 400°F (193°C to 204°C). This range is high enough to blister the skin and develop smoky flavor but gentle enough to cook the flesh evenly without charring it completely.
It’s worth noting that air fryer models can vary in heat intensity, so start at 390°F as a midpoint and monitor the peppers closely. Some air fryers may have hotspots, so shaking or rotating the peppers halfway through cooking ensures even roasting.

The cooking time for poblano peppers in an air fryer typically ranges from 10 to 15 minutes, depending on their size, thickness, and your air fryer’s power. Smaller peppers may be done closer to 10 minutes, while larger, more robust peppers might need the full 15 minutes.
A practical approach is to check at the 10-minute mark. If the skins are beginning to blister and char, they are nearing readiness, but larger peppers may need an additional 3-5 minutes. Always allow room for flexibility; the goal is a blistered, tender flesh rather than a fully blackened exterior.
Knowing when a poblano pepper is perfectly roasted is essential:
Once roasted, the peppers are typically placed in a covered bowl or a sealed plastic bag for 5-10 minutes. This ’sweating’ process loosens the skin, making peeling easier.
For basic air-fried roasted poblano peppers, you’ll need:
That’s it! Poblano peppers are naturally flavorful, and minimal ingredients are needed to achieve a smoky, roasted result.
Always adjust cooking time in tandem with temperature changes for consistent results.
Even experienced cooks encounter issues:
For roasting poblano peppers in an air fryer, set the temperature to 400°F (204°C). This high heat helps the skins blister and char evenly, which is essential for easy peeling and developing a smoky flavor.
Roasting poblano peppers in an air fryer typically takes 10-15 minutes. Shake or flip the peppers halfway through the cooking process to ensure they roast evenly on all sides.
Using oil is optional. Lightly brushing or spraying the peppers with oil can enhance browning and flavor, but they will roast successfully without it. The air fryer’s circulating heat is sufficient to blister the skins.
Poblano peppers are properly roasted when their skins are blistered, blackened in spots, and the flesh feels tender. The skin should lift easily when pressed or peeled after cooling slightly.
After roasting, place the peppers in a bowl and cover with a plate or plastic wrap for 5-10 minutes to let them steam. This loosens the skin, making it easy to peel off with your hands or a paper towel. Avoid rinsing under water, as it can wash away flavor.
It is not recommended to roast frozen poblano peppers directly, as they release excess moisture and will not blister properly. Thaw them completely and pat dry before roasting for best results.
Roasted poblano peppers are versatile. They can be used in salsas, soups, sauces, enchiladas, tacos, or stuffed with cheese or meat. They also add a smoky flavor when chopped and added to salads, rice dishes, or casseroles.
