Equipment

  • Air fryer (I use the Air Fryer Instant Vortex Plus XL)
  • Cutting board
  • Sharp knife
  • Small bowl for mixing oil and spices (if you are using these ingredients)
  • Kitchen tongs for easy flipping
  • Plate or serving dish for presentation

Ingredients

  • 6-8 fresh jalapenos
  • 1 teaspoon olive oil (optional)
  • salt to taste
  • black pepper to taste

Instructions

  • Wash and pat the jalapeños dry. For comfort, wear gloves while handling. Slice the peppers lengthwise; remove seeds and membranes for a milder result or leave some in for extra heat.
  • Preheat the air fryer to 370°F (190°C). Toss the jalapeños with olive oil (optional), salt, and black pepper. You can also cook them completely oil-free.
  • Arrange the halves in a single layer: skin side up for a crispier texture, cut side up for a softer inside. Leave space for air circulation.
  • Cook for 8–10 minutes at 370°F (190°C). Flip halfway through for even cooking.
  • Check doneness: the edges should be browned, the skin slightly wrinkled, and the flesh tender but holding its shape. Add 1–2 more minutes if needed.
  • Transfer to a plate or serving dish. As an added option, drizzle with some lime juice, sprinkle with smoked paprika, or chop to place in tacos, burgers, salads, and dips.

Notes

Cooking Time and Temperature

Air fry the jalapenos for 8–10 minutes, flipping halfway through and adding another 1–2 minutes if needed.

Taste & Texture

Smoky and pleasantly spicy with browned edges, slightly wrinkled skin, and a tender center that still holds its shape.

Storage, Freezing & Reheating

  • Refrigerator: Store cooked jalapenos in an airtight container in the refrigerator for up to 3 days.
  • Freezer: Freeze the jalapeno halves on a tray until solid, then transfer them to a freezer bag.
  • Reheat: Air fry for 3–4 minutes before serving.

Serving Recommendations

  • I like chopping these up for tacos or burgers when I want a little extra heat without adding another sauce.
  • Serve them alongside a dip or add them to a salad when you want to use the roasted jalapenos without much extra preparation.

Recipe Variations and Substitutions

  • Add a squeeze of lime juice before serving.
  • Top with cheddar, mozzarella, or cream cheese.
  • Sprinkle the jalapenos with smoked paprika.
  • Replace the jalapenos with green bell peppers, serrano peppers, Padrón peppers, or shishito peppers.
  • Use avocado or canola oil instead of olive oil.

Proper Storage Tips

  • Store cooked jalapenos in an airtight container.
  • Keep them refrigerated.
  • Use them within 3 days.

Pro Tips

  • Add smoked paprika, garlic powder, or lime juice when you want more flavor.
  • Look for slightly wrinkled skin, browned edges, and tender flesh that still holds its shape.
  • For extra flavor, marinate the jalapenos for 15–20 minutes in olive oil, garlic, and lemon juice before air frying.
  • Start at 370°F (190°C) for 8–10 minutes and adjust the cooking time as needed for your air fryer.
Air fryer models may vary. If the peppers darken too quickly, lower to 356°F (180°C); if still they still haven't changed colour after 8 minutes, increase to 392°F (200°C) or extend cooking in 1–2 minute increments.
