What Is a Red Serrano Chili?
The red serrano chili (Capsicum annuum) is a staple in Mexican cuisine, known for its bright red color, compact size, and sharp heat. It’s typically used fresh but can also be dried, smoked, or pickled. Originating from the mountainous regions of Puebla and Hidalgo in Mexico, the name comes from the Spanish word "sierra," meaning mountain range.
Heat Levels and Flavor Profile
When it comes to heat, the red serrano chili packs a punch! On the Scoville scale — which measures spiciness — these chilies range from 10,000 to 23,000 SHU (Scoville Heat Units). That makes them hotter than jalapeños but milder than habaneros.
Pepper Type | Scoville Heat Units (SHU) |
---|---|
Red Serrano Chili | 10,000 – 23,000 |
Jalapeño | 2,500 – 8,000 |
Habanero | 100,000 – 350,000 |
Bell Pepper | 0 |
In terms of flavor, red serranos offer more than just heat. They have a grassy, peppery taste with hints of citrus and earthiness. The flavor becomes richer and slightly smoky when they are roasted or dried.

Culinary Uses
One of the most versatile peppers around, the red serrano chili is perfect for adding zing to salsas, soups, stews, and sauces. Here are some of the top ways to use them:
- Salsas: Add chopped raw red serrano to your favorite salsa verde or tomato-based salsas.
- Stews and Soups: Throw a whole or sliced pepper into simmering beans or pozole for a slow-building heat.
- Pickling: Make quick-pickled serrano chilies to keep on hand for tacos or sandwiches.
- Cocktails: Muddle a small piece into a Bloody Mary or spicy margarita for an extra kick!
