Jalapeño poppers usually take about 15–25 minutes to cook , depending on your method and pepper size.

Quick Scoop (Core Timings)

  • Oven-baked (fresh, halved poppers):
    • 400°F (200°C) for 18–22 minutes , until the peppers are tender and the tops are golden and the cheese is melted.
  • Oven-baked (simple cheese + crumbs):
    • 400°F (200°C) for about 20 minutes , until jalapeños are tender and cheese is melted.
  • From frozen (unbaked, straight from freezer):
    • 425°F (220°C) for about 25–30 minutes , until hot in the center and browned on top.
  • Grilled, bacon-wrapped:
    • Indirect heat, lid closed, about 20–25 minutes , then a few minutes over direct heat to crisp the bacon.
  • Air fryer (halved, stuffed):
    • Around 325°F (160–165°C) for 12–15 minutes , until the tops are golden and the peppers are tender.

A good rule of thumb: they’re done when the cheese is fully melted and bubbling , the tops are lightly browned, and the jalapeño is tender but still holds its shape when you pick it up.
