How To Roast Jalapeno Peppers

Roasted Jalapeno Peppers

Jalapeno 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 PepperGeeks know that each jalapeno plant can produce more peppers than one knows what to do with. For a unique flavor and a tender texture, we recommend learning how to roast jalapeños yourself at home!

We have multiple methods for each unique scenario. 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 jalapenos for cooking or storing, skip ahead to learn more.

Skip Ahead:


Roasting Jalapenos In The Oven

The most accessible method for roasting jalapeños is at home in the oven. The only drawbacks of this method are that it is hot in the summer and turning your oven on will warm up your kitchen, and that the flavor 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 methods: Leave the peppers whole while roasting. Waiting to slice the peppers helps keep moisture locked in the peppers and can help make skin removal easier!

Ingredients:

  • Jalapenos
  • Oil (use something with a high smoke point like canola or EVOO)

How To Roast Jalapenos (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.

  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 peppers 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 jalapenos in the fridge for up to a week, or freeze them in freezer bags for several months. Learn more methods for using roasted jalapenos here.

This is a great method for roasting whole jalapenos 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 Jalapenos On The Grill

Whether you have a gas or charcoal grill, we recommend using it instead of the oven if possible. The peppers take on all the great flavors that come from grilling and lock them in. Just like chicken, grilling brings out that characteristic flavor that can only be had from this method. Whether it’s the outdoor air or the variable heat, we’re not sure. All we know if that the grill is the best way to maximize flavor for your roasted jalapenos!

Ingredients:

  • Jalapenos (that’s it, baby)

Roasting 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 400° (medium-high heat).
  2. Clean the peppers. Clean off any excess dirt using cool water. Dry the peppers when done.
  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.
  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 addition 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. Skip ahead to learn how to steam your roasted jalapenos here.
  7. Peel off skins. Slice the peppers lengthwise and remove the skins and seeds.
  8. Enjoy fresh or preserve them. What you do with the 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 compromise method of roasting jalapenos on the grill: over a gas stove.


Roasting Jalapenos On A Gas Stove

If you happen to have a gas stove, you can try roasting jalapenos over the open flame. This should be a sort of 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 jalapenos, so it might be worth it, especially if you don’t have many peppers!

Ingredients:

  • Jalapenos (yeah, we get it)

Roasting Jalapenos On A Gas Stove:

  1. Clean and dry the peppers. Use cool water to clean off excess dirt from the peppers. Dry with a towel.
  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 maintain focus.
  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. Skip ahead to learn how to steam your roasted jalapenos here.
  6. Remove skins. After steaming, remove the skins and use your peppers as desired.

Steaming & Peeling Roasted Jalapenos

Steaming is a crucial step for how to roast jalapenos. 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 jalapeno peppers to steam using their own moisture. There are two methods that work equally well.

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 and remove the pepper skins.

Good to know: The skin of the pepper is not needed because it is tough and bitter. The point of roasting jalapenos is to keep the sweet, fiery flavor of the pepper without any harshness from the skin!


The Best Uses For Roasted Jalapenos

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

Add Them To Egg or Potato Salads

These are a fantastic way to spice up potatoes or egg salads. Roasted jalapenos add a nice kick of spiciness and a fantastic, rich flavor. Alternatively, try adding these to scrambled eggs, tacos, sandwiches or anything other recipes you think could use some heat!

Stir Them Into Pasta Sauce

Jalapenos 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, “Whats the secret ingredient?”

Use Them To Make Dip

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

Fill Pepper Halves With Cream Cheese

Why not? You can make jalapeno poppers in reverse if you want. Live your life, man.

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 you can find a way to make it work.

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 jalapenos in olive oil recently, and roasting is the first step. Use these on sandwiches or in omelets for a great, 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.

  1. 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!
