Homemade roasted jalapeño salsa — simple, vibrant, and packed with heat. Made with just six mostly pantry ingredients, this roasted jalapeño sauce adds a bright, smoky kick to tacos, grilled meats, sandwiches, and any dish that benefits from fresh jalapeño flavor.
If you love spicy condiments and keep a few hot sauces in the fridge, this roasted jalapeño salsa belongs in your rotation. It’s more of a pourable sauce than a chunky chip dip — silky, smoky and bright from lime and cilantro. With only a handful of ingredients it’s quick to prepare, stores in the fridge for up to a week, and freezes beautifully for longer storage.
Growing a bumper crop of jalapeños or returning from the farmers market with a big bag? This recipe is ideal for preserving that harvest. It’s naturally gluten free, vegan, and low in carbs — a versatile condiment to boost flavor across many meals.
How to make it
Preheat the oven to 450°F. Arrange the jalapeños, halved onion, and garlic cloves on a roasting pan. Roast for 20–25 minutes, turning the peppers and onion every 5 minutes so they brown evenly. The roasted flavor comes from the caramelized, blistered skins, so aim for uniform browning on all sides.
Allow the vegetables to cool about 10 minutes. Peel the skins from the jalapeños and garlic (peeling helps the salsa blend to a smooth texture and reduces any overly bitter char). Add the jalapeños, onion, peeled garlic, cilantro (including tender stems), lime juice, oil and salt to a high-speed blender or food processor.
Blend until smooth and bright green. Taste and adjust salt or lime to preference. Serve immediately or transfer to an airtight container for storage.
How to use it
This salsa functions like a hot sauce: use it to add heat and brightness rather than as a chip dip. It pairs especially well with:
- Grilled chicken tacos
- Portobello or vegetable fajitas
- Spinach quesadillas
It’s also excellent spooned over scrambled eggs, grilled shrimp, roasted vegetables, or mixed into mayo or crema for a spicy spread. Use it anywhere you want a fresh jalapeño punch similar to pickled jalapeños but with smoky roasted depth.
How to store it
Keep the salsa in an airtight container in the refrigerator for up to one week. For longer storage, freeze the sauce—ice cube trays work great for portioned cubes you can thaw as needed for quick servings.
