What Is a Serrano Chili?

The serrano chili (Capsicum annuum var. longum) is a medium-sized chili pepper native to Mexico, named after the mountainous regions known as “sierras.” These peppers are typically 2–4 inches long and are often used fresh or pickled in Mexican cuisine, especially in salsas, soups, and sauces.

Unlike jalapeños, which are usually harvested once they turn red, serranos can be used at any stage of maturity — green, orange, red, brown, or even black. Their flavor profile varies depending on the color, with green ones being more grassy and red ones sweeter and smokier.

How Hot Are Serrano Chilies?

On the Scoville scale, which measures spiciness, serrano peppers range from 10,000 to 23,000 SHU (Scoville Heat Units). For context:

Pepper SHU Range
Red Bell Pepper 0
Jalapeño 2,500–8,000
Serrano 10,000–23,000
Cayenne 30,000–50,000

So yes, serranos bring the heat! But unlike hotter peppers, their spiciness is clean and doesn’t linger too long, making them ideal for those who want to experience spice without going nuclear.

Serrano chilies come in a rainbow of colors — each with its own unique flavor profile. Here’s a breakdown:

Color Flavor Notes Best Use
Green Grassy, bright, vegetal Salsas, garnishes, raw dishes
Orange Fruity, slightly sweet Ceviches, marinades
Red Smoky, rich, slightly sweet Romesco, sauces, roasting
Brown/Black Earthy, intense, concentrated Stews, moles, dried powders

5 Must-Try Cooking Tips with Serrano Chilies

  • Use the seeds for extra heat — Unlike jalapeños, where the seeds are optional, serrano seeds pack a punch. Leave them in for more spice!
  • Roast them for depth — Charred serranos add a beautiful smoky flavor to sauces and salsas. Simply hold over a flame or roast under the broiler until blistered.
  • Pickle them for longevity — Pickling serranos in vinegar, garlic, and spices keeps them fresh and adds tangy complexity. Great on sandwiches or tacos!
  • Blend into smooth sauces — Puree roasted serranos with tomatillos, cilantro, lime, and onion for an epic green sauce.
  • Balance with citrus or dairy — Lime juice or sour cream tames the heat while highlighting the pepper’s natural brightness.
