Ingredients

  • Raw Jalapeños: Fresh, firm peppers are best. Keep them whole or halve them, and remove seeds for less heat.
  • Olive Oil: A light drizzle helps the jalapeños roast evenly and enhances their smoky flavor.
  • Salt (Optional): Adds seasoning to balance the spice, or customize with other spices like garlic powder or cumin.

 

Step By Step Instructions

Follow my easy method for making the best-roasted jalapeño peppers.

Step 1: Preheat your oven Set the oven to 425°F (220°C).

Step 2: Prepare the jalapeños Wash and dry the jalapeños. You can either leave them whole or cut them in half lengthwise. Option to remove the seeds and ribs to reduce the spiciness.

Step 3: Toss in oil In a large bowl, drizzle olive oil over the jalapeños and toss to coat evenly. Sprinkle with salt if using.

Step 4: Roast Place the jalapeños on a roasting pan or baking sheet in a single layer, cut side down if halved. Roast for 15-20 minutes or until the skin blisters and the peppers become slightly charred.

How To Store

Once the jalapenos have cooled, place them in an airtight container and store them in the refrigerator for up to 1 week.

Flash Freeze (Optional): Spread the cooled jalapeños on a baking sheet in a single layer and freeze them for 1-2 hours. This prevents them from sticking together later.

Transfer to Freezer Bags: After freezing, place the jalapeños in a resealable freezer-safe container. Remove as much air as possible. Keep in the freezer for up to 6 months.

Bonus Ways to Make Roasted Jalapeños

Try these alternative methods to make it easy to roast jalapeños no matter what equipment you have on hand!

Grill Method:

Preheat the grill to medium-high heat. Place whole or halved jalapeños directly on the grill grates. Grill for 5-10 minutes, turning occasionally, until the skin blisters and chars.

Stovetop Method:

Heat a cast iron skillet over medium-high heat. Place whole or halved jalapeños in the dry pan and cook for about 5-8 minutes, turning occasionally, until the skin blackens and the peppers soften.

Air Fryer Method(My Fave)

Preheat the air fryer to 375°F (190°C). Arrange the whole or halved jalapeños in the air fryer basket. Cook for 8-10 minutes, shaking halfway through, until blistered and slightly charred.

Make A Roasted Jalapeno Hot Sauce (No-Recipe Recipe)

Roast a handful of roasted jalapeños (6-8), and keep seeds if you want extra heat. Toss them in a blender with a couple of garlic cloves, a about 1/2 cup of vinegar (white or apple cider or both!), 1-2 tbsp honey for sweetness, and ~1/2 tsp salt. Add a little water (2-4 tbsp) to get the consistency you like. 

Blend those until smooth, adjusting salt and honey to taste. Pour it into a jar, and that’s it! You’ve got a smoky, tangy hot sauce to spice up tacos, eggs, grilled meats, or whatever you like. 

This roasted jalapeno hot sauce will be kept in the fridge for up to two weeks!
