These Roasted Jalapeno has a deep, smoky flavor, making them perfect for adding a spicy kick to any meal. My version of roasting is incredibly simple—made with just three ingredients and effortless to prepare in large batches.

I grow jalapeño plants in my backyard and harvest them every other day. If you are like me, who often ends up with more jalapeños than you can use, roasting them is a great way to preserve their bold flavor for months.
But roasting isn’t just about storage—it also mellows down the heat and enhances the flavor of jalapeños. Their blistered skin(like this roasted mini peppers), charred edges, and smoky aroma add a deep, spicy kick to salads, sauces, and soups.
Whether you're roasting for storage or flavor, one thing is sure—you'll love the soft texture, and toned heat that roasted jalapeño brings to every bite!

Ingredients
- Jalapeños: Look for fresh, shiny jalapeños without any dark spots. Smaller jalapeños are spicier than larger ones. The chili pepper oils are most concentrated in the center and ribs, which can cause skin irritation. Always wear gloves to avoid discomfort.
- Grape Seed Oil: I used grape seed oil(which complements the smoky flavors), but you can substitute with avocado oil, olive oil, canola oil, or any neutral oil you choose.
- Salt: I used kosher salt, but feel free to use any salt you prefer, such as sea salt or Himalayan salt.
How To Make Roasted Jalapenos
- Preheat the oven to 400°F. Slice the jalapeño peppers and arrange them on a tray without crowding. Drizzle the grape seed oil evenly over the peppers and bake for 10 minutes or until the edges are charred.
- Remove the tray from the oven, transfer the roasted jalapeños to a bowl, cover with a lid, and let them steam for about 5 minutes. This helps loosen the skin, making it easier to peel off. Then use in making salsa or soup.
♨️How To Adjust The Heat Level
- These roasted jalapeno peppers are medium-hot.
- Heat tolerance varies from person to person. Some may find them mild, while others feel the spice instantly. The good news is you can easily adjust their heat level to your preference.
- If you prefer a milder spice level, remove all the seeds and ribs before roasting.
- For a balanced level of spice, leave some seeds and ribs.
- For those who love wholesome heat, keep all the seeds and ribs for a spicier kick. This retains the full intensity of the jalapeños, making them perfect for extra heat to any dish.
The Leftovers
- You can store the roasted jalapeno in the refrigerator for up to 5 days or in the freezer for up to 6 months.
- To use frozen jalapeños, thaw them in the refrigerator overnight or add them directly to salsas, soups, or sauces—there is no need to reheat.
- If you prefer to warm them, reheat them in the oven at 350°F for about 10 minutes or briefly microwave them until warm.
How To Use
- Blend them into salsa, guacamole, and other ingredients for a smoky kick.
- Mince and mix them into scrambled eggs, pasta, or even pizza toppings for added heat.
- Use them as a layer in tacos, burgers, or sandwiches for a spicy boost.
- To enhance flavor, chop and sprinkle them over soups, salads, or nachos.
FAQ
Absolutely(this roasted shishito peppers recipe is an example)! You can follow the same roasting technique for other peppers, like poblano, serrano, or bell pepper. However, each pepper varies in thickness and size, so adjust the roasting time accordingly.
Apart from salt, you can add garlic powder, chili powder, or even a splash of lime juice. Each addition brings a new layer of flavor, so feel free to experiment and find your favorite combination! Let me know how it turns out.
Peeling roasted jalapeños is a personal preference. The skin adds a slightly smoky flavor and texture, so you can leave it on too.
Yes! Grilling is a great option. Grill the jalapeños over medium to high heat for about 8 minutes, turning occasionally until they are evenly charred.
The stovetop method is quick and easy if you only need to roast a few jalapeños. Place them directly over a gas flame, wait until the skin is blistered and charred, then turn to the other side using tongs. Repeat until the entire surface is roasted.
