Preheat oven or air fryer to 400°F. Spread the jalapenos in a single layer on a baking sheet, allowing space between the peppers. Roast jalapenos for 11 minutes or until slightly charred on top.
Flip the jalapenos and roast on the other side for additional 7-8 minutes. The skin should start separating from the flesh of the jalapeno.
Remove peppers from the baking sheet and transfer to a container and cover for 10 minutes to create steam.
Peel the skin off the jalapenos and pinch off the stem. The skin should release easily. Store the peeled jalapenos in an airtight container.
Notes
Recipe makes approximately 1 ½ cups of roasted jalapenos. Serving size is ½ pepper. Storage: Store jalapenos in an airtight container in the fridge for up to 2 weeks. To extend shelf life, submerge them in olive oil and store in the fridge for up to 3 months. You can also freeze the peppers (with or without) the oil for up to 12 months. Helpful tips:
Keep the stems on: It makes handling the peppers easier, especially when turning them over.
Use a glass container: To easily remove the membrane, use an airtight container instead of a plastic baggie as the steam may pull toxins from the plastic.
Peel while warm. It's easier to remove the membrane (skin) while the peppers are still warm, so don't wait too long after roasting and steaming the peppers to do this step. For stubborn parts, use a good paring knife.
Mind the time: The roasting time will depend on the size of the jalapenos. The time indicated above is for small jalapenos. Increase time for larger peppers.
Remove seeds. If the peppers are too spicy, gently scrape off the seeds and interior membranes.
