📖 What are chiles serranos?
Serrano peppers are probably the second most popular chile next to jalapeño peppers. But, they are often mistaken for one another!
Serrano chiles were named after mountain ranges (sierras) in the Mexican states of Hidalgo and Puebla.
These green beauties are typically between 1-4 inches long and ½ an inch wide. While you may find them sold red, brown, or yellow, the most common color is green.
Because of how dense this pepper is, it isn't often dried. Instead, serrano peppers are usually roasted or sliced raw to be added to many dishes.
🍴 Flavor profile
In their fresh form, green serrano chiles carry a bright, vibrant, garden-vegetable flavor — very similar to jalapeños.
🔥 Spice level
Serrano peppers sit around 10,000-23,000 Scoville Heat Units (SHU), making them a medium heat chile.
Compared to jalapeño peppers, the chile serrano is 3 times hotter on average. You can really expect a noticeable difference in spice.
🍎 Health facts
These tiny peppers add a lot of spice and flavor to recipes, but they also come with quite a few health benefits.
Serrano chiles are low in calories, high in fiber, and contain vitamin A and C. Both of these antioxidants are helpful in maintaining healthy eyes and youthful skin.
Serrano peppers also contain a nutrient, called capsaicin, which is responsible for their spicy nature. Capsaicin is currently being studied for its positive effects on the vascular system and improvements in heart health.

💰 Buying guide
Now that you're convinced serranos should be in your next meal, take a peek at the following tips to source the freshest serrano peppers possible.
What to look for
Look for serrano chiles that are firm and plump, but have a slight give when you push on them. Avoid those chiles with bruises, wrinkles, or soft spots.
If the serranos you're eyeing up have thin tan lines on them, don't worry! These lines simply indicate the plant was under more stress at some point and the pepper is typically sweeter and spicier.
Where to buy
Serrano peppers are a fairly easy chile variety to find in most places around the world. You should be able to find them in the produce section next to jalapeño peppers. Just be careful you don't mix the two up!
Because serrano peppers have a bright, fresh, and grassy flavor, there are a few different peppers you can substitute if you're in a bind:
- Jalapeño. Probably the most convenient substitute for serrano chiles are jalapeño peppers. While similar in flavor, they are more mild in terms of spice. If that's not a deal breaker, use them at a 1:1 ratio.
- Poblano. With more complex flavors, poblano peppers also make a good choice to replace serranos. However, they too won't be near as spicy.
