Serrano Pepper
10,000–23,000 SHU — Medium-HotThe serrano is the pepper of choice for many Mexican cooks who want more heat than a jalapeño delivers. Smaller, thinner, and significantly hotter, serranos have a bright, fresh, grassy flavor that works beautifully in fresh preparations like salsa verde and guacamole.
Serrano vs. Jalapeño
Serrano
- • Smaller (1–4 inches) and thinner-walled
- • 3–5x hotter than a jalapeño
- • Brighter, crisper, grassier flavor
- • Best used fresh — too thin-skinned to roast easily
Jalapeño
- • Larger (2–4 inches) and thick-walled
- • Milder heat, more predictable
- • Richer, slightly earthier flavor
- • Great roasted, stuffed, pickled
Best Uses
Fresh Salsa Verde
The traditional pepper for tomatillo-based green salsa — blended raw or fire-roasted
Pico de Gallo
Swap for jalapeño for a significantly spicier fresh salsa
Guacamole
Mince very finely — a little goes a long way in heat
Garnish
Thinly sliced raw serrano rings are a common garnish on tacos and soups in Mexico
Storage
Refrigerate in the crisper for up to 2 weeks. Their thin skin means they dry out faster than jalapeños — use sooner rather than later. They also freeze well: chop and freeze flat before bagging.
