Before You Get Started
- Move your oven rack to the highest position near your broiler element to ensure your jalapeños char quickly and evenly. Preheat your oven to 450 degrees.
- For easy cooking, pre-measure the olive oil and liquid smoke in a small bowl. Wash and dry the jalapeños thoroughly before roasting to prevent excess moisture from interfering with blistering.
- You don’t need anything fancy! A baking sheet and parchment paper work great for oven-roasting, while tongs make flipping the peppers easy.
Key Ingredients For Roasted Jalapeño Peppers
Here’s a quick overview of what you’ll need. For exact measurements, see the recipe card at the bottom of this post.
- Jalapeño peppers: Look for medium- to large-sized jalapeños that are firm, smooth, and deep green in color. Wrinkled or soft peppers may be past their prime. If you prefer extra heat, choose jalapeños with white striations (stretch marks), as they tend to be spicier.
- Olive oil: Use a good-quality olive oil for a rich, slightly fruity flavor that enhances the smokiness of the peppers. If you’re out of olive oil, avocado oil is a great alternative due to its high smoke point.
- Liquid smoke: Hickory and mesquite varieties work best for adding depth to roasted jalapeños.
How To Roast Jalapeños
Roasting jalapeños is an easy way to bring out their smoky, caramelized flavor with just a few simple steps.
Step 1: Prepare The Peppers
Using a sharp paring knife, slice off the jalapeño tops. Make a vertical cut down one side, stopping 1/2 inch from the tip. Gently open the pepper, grab the stem, and pull out the seeds and core.
Loosen any remaining seeds with your thumb and tap the pepper to remove them. Place cleaned jalapeños in a large bowl. In a separate bowl, whisk olive oil and liquid smoke. Drizzle over the jalapeños and toss to coat evenly.
Pro Tip: Wear gloves to avoid skin irritation.
Step 2: Roast, Steam, And Peel
Line a baking sheet with parchment paper and spread the jalapeños in a single layer, leaving 1/2 inch between each. Roast for 5 minutes, flip with tongs and roast for 5 more minutes until blistered and slightly charred.
Cover the pan with foil and let steam for 15 minutes to loosen the skins. Uncover and gently peel off the thin skin.
Pro Tip: Leave any small blackened bits because this adds flavor.
Step 3: Enjoy
Now, it’s time to enjoy your roasted jalapeños. Use the soft, smoky flesh of the peppers in your favorite dishes, from tacos and dips to sandwiches and salsas. These roasted jalapeños are more than just an ingredient. They’re a small but powerful way to add warmth and bold flavor to your table, making every gathering a little more memorable.
Tips and Variations
- If you’re watching your oil intake, you can roast the jalapeños dry and add a light drizzle of olive oil with the liquid smoke after roasting for flavor.
- Add a squeeze of fresh lime juice after roasting to balance the spice beautifully.
- If you prefer crispier jalapeños, roast them without oil and leave the skins on for a satisfying bite.
Storage And Reheating Instructions
- Let your roasted jalapeños cool completely, then store them in an airtight container or zip-top bag in the refrigerator for up to 5 days. For longer storage, freeze them in a single layer on a baking sheet before transferring to a freezer-safe bag, where they’ll keep for up to 3 months.
- No need to reheat if you mix them into soups, sauces, or casseroles (simply toss them in), You can also use them straight from the fridge if you add them to salsas, salads, sandwiches, or dips. For warm dishes, reheat them in a hot skillet for 1-2 minutes or place them under the broiler for a quick char to bring back some of their fresh-roasted heat.
Roasting jalapeños can make them taste milder, especially if you remove the seeds and membranes before or after roasting. If you love the heat, leave them in for an extra kick.
It depends on how you’re using them. If you want a smoother texture for salsas, sauces, or dips, peel them. You can leave skin on if you enjoy the smoky, charred flavor and don’t mind a bit of texture for your tacos, nachos, or roasted veggie platters.
Serving Ideas & Pairings
Hosting tip: Present roasted jalapeños on a beautiful charcuterie board, surrounded by an array of cheeses, crackers, and fresh fruits.

Biblical Hospitality Reflection
Roasting jalapeños transforms them—intensifying their flavor, softening their texture, and deepening their richness. The heat of the oven doesn’t destroy them; it refines them, bringing out their best qualities. In the same way, our faith is often tested and strengthened through trials.
“These trials will show that your faith is genuine. It is being tested as fire tests and purifies gold—though your faith is far more precious than mere gold.” — 1 Peter 1:7 (NLT)
Just like jalapeños become richer and more flavorful when exposed to heat, our faith grows stronger when we walk through life’s challenges with trust in God. When things feel overwhelming, remember that God is using the refining fire to shape you into something even more beautiful.
Table Talk: Ask those around your table. Can you think of a time when a difficult season in your life deepened your faith or brought out unexpected blessings?

Ingredients
- 8 jalapenos, medium to large sized
- 1 1/2 tablespoons olive oil
- 1/4 teaspoon liquid smoke
Instructions
- Move your oven rack to the highest position near your broiler element. Preheat your oven to 450 degrees.
- Wash your peppers well under warm water. Place them on a towel and pat them dry.8 jalapenos
- With a small sharp paring knife, cut the top off then vertically from the top cut one side stopping 1/2 inch before the tip. Gently open the pepper and grab the stem and pull out the pepper’s center and seeds. Use your thumb to clean out anything not coming loose and tap out the seeds. Toss the whole cored pepper into a large bowl.
- Whisk in a small bowl the olive oil and liquid smoke. Drizzle the oil mixture over the peppers in the bowl and toss gently.1/4 teaspoon liquid smoke, 1 1/2 tablespoons olive oil
- Lay pepper on a parchment-lined prepared baking sheet. Be sure and leave 1/2 inch space between each pepper.
- Roast for 5 minutes, then turn peppers over—roast for 5 more minutes.
- After the 5-minute mark is up, remove the pan of peppers from the oven and quickly cover the whole pan with aluminum foil. Be very careful to seal the foil all around the edges of the pan so the peppers can be steamed. Allow the peppers to sit and steam for 15 minutes.
- Remove foil and gently pull off the outer skin of the roasted jalapeno pepper. Don’t worry about the blackened bits on the skin, just peel it off. The skin of the pepper is a little papery and is better discarded, using only the soft flesh in your recipes.
Notes
- First and foremost, wear a pair of single-use disposable gloves to cover the sensitive skin on your hands. I keep a box of these in my kitchen when I prepare hot peppers or work with raw meat.
- Remember, even though you have gloves on, don’t touch any other part of your body while working with the hot peppers.
- Use a large cutting board that can be put into the dishwasher after you are done. The oils can remain on the board unless you wash them with a lot of soap and hot water.
- Cover your baking pan with parchment paper for easy clean-up.
- Roast jalapenos whole. This helps retain moisture and makes it easier to peel the skin off.
