How To Roast Jalapeño Peppers

For a unique flavor and a tender texture, we recommend learning how to roast jalapeño peppers at home. They are perfect for pasta sauce, potato salad, or fresh chip dips. It’s also an incredibly easy process!

Jalapeño peppers are some of the most common spicy peppers in the world. Grown in bulk in Mexico and the United States, it is easy to see why the pepper is so beloved. However, fellow Pepper Geeks know that each jalapeño plant can produce more peppers than one knows what to do with.

Roasted Jalapeno Peppers

We have a few methods for roasting jalapeños depending on your available equipment. Whether you have a grill or you want to roast in your oven, we’ll show you the best way here. If you’re just looking for how to use your roasted jalapeños for cooking or storing, skip ahead to learn more.

Skip Ahead:

Roasting Jalapeños In The Oven

The most accessible method for roasting jalapeños is at home in the oven.

The flavor of oven-roasted jalapeños is not as pronounced as over the grill. Nevertheless, this is still a very quick and easy method for getting the job done!

Tip for all roasting methods: Leave the peppers whole while roasting. Waiting to slice the peppers helps keep moisture locked inside the peppers and makes skin removal easier.

  • Oil (use an oil with a high smoke point like canola or EVOO)

How To Roast Jalapeños (Directions):

Prep & cook time: 20 minutes

  1. Move oven rack to highest (broiling) position.

    This ensures that the peppers are as close as possible to the oven’s heating element for quick charring.

  2. Preheat the oven to 450°F.

    This is the optimal temperature for roasting your peppers.

  3. Clean the peppers.

    While the oven is preheating, prepare your peppers by cleaning them thoroughly under cool water. Dry the peppers as well to ensure the oil sticks to the peppers before baking.

  4. Remove the stems.

    Remove the pepper stems by simply pulling them off. If the stems are stubborn to come free, you can slice off the very end of each pepper with a knife.De-Stemmed Jalapenos

  5. Place peppers on a baking sheet & lightly coat with oil.

    Keep the jalapeños separated by about 1 inch. Ensure peppers have an even coating of oil. For enhanced flavor, add a pinch of salt to the oil prior to coating.Baking Jalapeno Peppers

  6. Roast for 5 minutes on each side.

    Watch the peppers closely and turn them when they begin to char. Then flip the peppers and roast an additional 5+ minutes on the other side.Roasting Jalapeno Peppers

  7. Steam the peppers.

  8. Peel the skins off.

    Once you have allowed the hot peppers to steam, the skins should come off fairly easily. Slice the peppers lengthwise, remove the pepper skins and discard them. You can also remove the seeds at this point if desired (remember to wear gloves!).Peeling Roasted Jalapenos

  9. Enjoy fresh or store the peppers.

    You can store roasted jalapeños in the fridge for up to a week, or freeze them in freezer bags for several months. Learn more methods for using roasted jalapeños here.

This is a great method for roasting jalapeños in the oven and makes it easy to roast a lot of peppers at the same time. For a little more flavor, try our next method: On the grill.

Roasting Jalapeños On The Grill

Whether you have a gas or charcoal grill, we recommend this option instead of the oven if possible. The peppers take on all the great flavors that come from grilling and lock them in.

Just like with chicken, grilling brings out that characteristic flavor that can only be had from this method. The grill is the best way to maximize flavor for your roasted jalapeños!

Roasting Peppers on the Grill (Directions):

  1. Fire up the grill. If you’re using a charcoal grill, let the heat come down for about 15-20 minutes. If you have a temperature gauge (like on a gas grill) shoot for around 450°F (high heat).
  2. Clean the peppers. Clean off any excess dirt using cool water, dry the peppers, and remove the stems.
  3. Place whole peppers on the grill. Once the grill has reached the required temperature, place your peppers on the grill above the heat, spacing them by around 1-2 inches. Note: You can lightly coat the peppers in a high smoke point oil, but this isn’t required.
  4. Grill for 5 minutes with lid closed. You want to peppers to get a nice, dark charring on the skins. If the temperature is adequately high, this should start to happen after about 5 minutes. Check the peppers once or twice to avoid over-cooking.
  5. Turn the peppers and cook an additional 4-5 minutes. Flip the peppers so the charred side is up, and cook for another 4-5 minutes. If the peppers are not charring, keep them on until the skins reach your desired color. The peppers should also be soft and pliable at this point.
  6. Steam the peppers. See below to learn how to steam roasted jalapenos.
  7. Peel off skins. Slice the peppers lengthwise and remove the skins and seeds.
  8. Enjoy fresh or preserve. What you do with your roasted peppers is up to you!

Like I said before, grilling is the ideal option. However, we know that not everyone has a grill. But you may just have a gas stovetop in your kitchen. If you do, you may want to try the compromised method of roasting jalapeños on the grill: Over a gas stove.

Roasting Jalapeños On A Gas Stove

If you happen to have a gas stove, you can try roasting jalapeños over an open flame. This should be a last resort, as it will be time-consuming to roast the peppers one or two at a time.

It can also be dangerous. However, the result may be tastier than oven-roasted jalapeños, so it might be worth it (especially if you don’t have many peppers).

Roasting Jalapenos On A Gas Stove:

  1. Clean and dry the peppers. Use cool water to clean off excess dirt from the peppers and dry them thoroughly.
  2. Remove stems. Pull the stems off of each pepper that you plan to roast.
  3. Skewer peppers on long metal prong. You’ll need a long, sharp prong (ideally a metal roasting fork – these are great on Amazon) to avoid getting burned. We’d also recommend roasting one pepper at a time so that you can keep focused.
  4. Roast for 3-5 minutes. Wearing an oven mitt, roast the jalapeños over the open flame, keeping the pepper about 2 inches above the fire. Turn the pepper after each minute of roasting for even charring. Warning: be prepared for the possibility of fire! Be careful not to touch the pepper to the flame and have some water nearby to submerge the pepper in an emergency.
  5. Steam the peppers (see below).
  6. Remove skins. After steaming, remove the skins and use your peppers as desired.

Steaming & Peeling Roasted Jalapeños

Steaming is an important step for how to roast jalapeños. If you remove the peppers from the heat and immediately tried removing the skins, you will:

  • A. Burn yourself (ouch).
  • B. Struggle to get the skins off.

So in order to fix both of these problems, we allow the freshly roasted jalapeño peppers to steam using their own moisture. There are two methods that work equally well.

Check out our recipe for stuffed pepper soup which uses roasted and steamed bell peppers!

How to Steam Roasted Peppers:

Option 1: Place peppers under a bowl. Using a clean surface (like a cutting board), place the hot peppers close together. Place the bowl over the peppers upside down, sealing tightly so that no air can escape. Alternatively, simply place them in a bowl and cover with a silicone bowl cover. Allow to steam (and cool) for 15+ minutes. Then proceed to remove the pepper skins.

Steaming Roasted Peppers

Option 2: Place peppers in a paper bag. Place the freshly roasted peppers in a paper bag and close it tightly. This will trap moisture (though not as well as the bowl method) and loosen the skins. Allow to steam for 15+ minutes, then remove the pepper skins.

Why remove the skin? The skin of the pepper is not needed because it is tough and slightly bitter. The point of roasting jalapeños is to keep the sweet, fiery flavor of the pepper without any harshness from the skin! Also, if making hot sauce, the skin is hard to finely chop.

What To Do With Roasted Jalapeños

So you’ve learned how to roast jalapeños, but what now? Didn’t have a plan beyond the roasting part? Well, here are a few ideas for what to do next with your freshly roasted jalapeños.

Add Them To Egg or Potato Salads

Roasted jalapeños are a fantastic way to spice up potato or egg salads. They will add a nice kick of spiciness and a fantastic, rich, sweet flavor. Alternatively, try adding these to omelets, tacos, sandwiches or anything other recipes you think could use some heat!

Stir Them Into Pasta Sauce

Jalapeños add a mild, tolerable heat to any tomato sauce. We love the roasted flavor and the spicy kick that comes with it. They also add a speckled green and black color to your sauces, prompting your guests to ask, “What’s the secret ingredient?”

Use Them To Make Dip

Salsa, sour cream dip, whatever you’ve got in mind. Jalapeños are a must have for fresh-made dips in our household, and roasted jalapeños add a different character. You can use fresh jalapeños or cooked in dips, but there is something about the soft, rich flavor of roasted jalapeños that makes our mouths water. Try adding a few to our roasted red pepper dip.

Fill Pepper Halves With Cream Cheese

Cream cheese and jalapeno peppers are the perfect pair. Our smoked jalapeno dip illustrates this point perfectly.

Whip up some cream cheese, herbs and spices and a bit of sprinkled cheddar and you’ve got yourself a batch of tasty hors d’oeuvres. It may be a little messy since the peppers won’t have any rigidity, but it will still be delicious.

Store Them In Oil

This is not a long-term storage method, but it is great for the short term. We wrote about how to preserve jalapeños in olive oil, and roasting is the first step. Use these on sandwiches or on eggs for a smooth, rich flavor.

Freeze Them

Not ready to use your roasted peppers just yet? No problem. Get yourself some proper freezer bags and freeze your roasted peppers for months. They will retain that great, roasted flavor even after months of freezing. Just be sure to freeze them properly! Check out our guide to freezing jalapenos here.

How Long Do Roasted Jalapeños Last?

After roasting jalapeño peppers, you may wonder how long they will last. Their shelf life duration will depend on how you plan to store them.

In a nutshell, roasted jalapenos will last between 1-2 weeks in the refrigerator. Shelf life can be prolonged by freezing or making hot sauce. Use your roasted peppers with our suggested techniques above.

If you suspect the peppers have gone bad, it is best to discard them. Check for fuzzy mold growth on the roasted jalapeños before consuming!

Does Roasting Jalapeños Make Them Milder?

You may wonder if roasting your jalapeños will reduce the heat level. Does cooking peppers make them milder?

Simply put, roasting jalapeños can make them slightly milder than when eaten fresh. According to one study, cooking at high heat can cause thermal decomposition of capsaicin in the peppers.

Most of the heat of jalapeño peppers lies in the placenta, the white, spongey section of the pepper that holds the seeds. If you want to reduce heat further, try removing the seeds and placenta with a spoon after roasting. Remember to always wear gloves when slicing spicy peppers!

Great article for Colorado resident for the last 45yrs. Peppers of all varieties were available everywhere. I now live in Upstate N.Y. and jalapeños are it. Darn!!! I miss my fresh poblanos. The smell of roasted poblanos in the late summer early fall at every farmers market and on several blocks in the right neighborhood is addictive. It drives me into the kitchen. I do miss those days. This article is a fantastic reference. Great job!

🥲 That sounds amazing. I hope we can visit the Southwest during chile season some day soon.

I grew jalapeños this year and had good yield but they were all well undersized. Where did I go wrong?

Hi Calvin! I love growing jalapeno peppers, my husband takes pride in picking them and sharing with our neighbors! I still have lots on my hands. I was wondering if adding a bit of some kind of vinegar to the oil when preserving would be good, kind of pickling for sandwiches! I make poppers, my family loves them and i use it in my chili and black beans! Happy Gardening and Playing music! Mimi, 8/7/2020

Hi Mimi,

We usually preserve our jalapenos by either quick-pickling (combination of water and vinegar, spices & salt) or by freezing. Oil is a great short-term preservation method, but the crunchy quick-pickling method is the most delicious!

Here is an article with the general idea: Pickled shishito peppers

Hope this helps, and enjoy those peppers! -Calvin
