How to Roast Jalapeños in an Air Fryer

Roasted Jalapeños | Jalapeño peppers take on a charred, milder and sweeter flavor when they’re roasted. You can roast jalapeño peppers whole or halved, and with the seeds or deseeded. Roasted jalapeños are a great addition to grain bowls and potato bowls. You can blend them into sauces or eat them whole. Add them to salads, nachos, burgers, or sandwiches.

Learn how to roast jalapeños in the air-fryer and you’ll be adding them to every dish for the next month. Roasted jalapenos are soft, with a hint of smoke, and a nice mellow heat.

Roasting jalapenos is super easy. Lightly coat the peppers in oil and season with salt and pepper (or just salt) and bake them in the air fryer for about 10 minutes – simple!

Does roasting jalapeños make them milder?

When you roast jalapeños, the heat breaks down the capsaicin – the compound that makes peppers spicy – and results in a more mellow heat while adding a smoky flavor.

You can lessen the heat further by deseeding the peppers before roasting them.

Capsaicin can end up on your skin when working with jalapeños and can feel like burning or stinging. No fun! Wear gloves when handling these spicy peppers, unless you like to be careful/risk it like me.

If you don’t wear gloves, wash your hands thoroughly directly after and don’t touch your face before washing!

Ingredients

This is a brief overview of the ingredients used in this recipe followed by substitution ideas. Read the recipe card for measurements.

  • jalapeño peppers: In my grocery store jalapeños usually come in packs of 5-7 so that’s how many I roast but you can roast as many fit in your air fryer while still leaving space between (about an inch).
  • olive oil: for flavor and to help char the outside of the peppers. 
  • salt and pepper: for seasoning. I use kosher salt and fresh cracked black pepper.

Substitutions

  • Use whatever oil you prefer, like canola oil, peanut oil, avocado oil, or grapeseed oil. Use a spray oil for ease.

Remember to space the peppers out in the basket or baking pan, leaving an inch between peppers so they char and don’t steam.

How to peel a roasted jalapeño.

Place the hot roasted jalapeños in a bowl and cover it with a lid. Let them sit and steam for 10-15 minutes. Once they’ve steamed it’ll be easy to peel the skin or scrape it off with a spoon or knife. I don’t peel mine because I like all of the charred flavors.

Tips for How to Roast Jalapeños

  • gloves: wear gloves to protect your skin from capsaicin – this is the compound in chilies that makes them spicy. It can stick to your skin and cause a burning or stinging sensation. Wearing gloves helps to prevent this.
  • give them space: When roasting anything in the oven or air fryer, leave space between each item. Squishing ingredients together can cause them to steam instead of char and crisp up.
  • deseed: Want a less spicy pepper? Slice the jalapeños in half and scrape out the seed and white membrane – this is where most of the heat is in a pepper.
  • steam: Want to peel the charred skin off of your roasted jalapeños? Place the hot roasted peppers in a bowl and cover with a lid or plastic wrap and let them sit for 10-15 minutes to steam. This will make the skin easier to peel off. You might want to do this when making a sauce.

What to serve with roasted jalapeños

I like having these charred peppers on the side of a Loaded Potato Bowl. Roasted jalapeños would be great on a veggie burger, in tacos, on sandwiches or blended up in a sauce.

Storage

Store in the fridge for up to a week. Freeze, tightly wrapped or sealed in a bag or container for 3 months.
