Serrano peppers are chili peppers with big flavor that are very popular in Mexican cuisine! Learn more about them here and get our favorite recipes to use them in, too!
How hot are serrano peppers?
Serrano peppers are hotter than a jalapeno pepper, but not as spicy as a habanero. They give you a burst of heat while still remaining bright and flavorful.
On the Scoville Scale, serranos are ranked 8,000-22,000 SHU. For reference, bell peppers have a rank of zero and jalapenos are at about 5,000 SHU.
As a general rule, the smaller the pepper, the spicier it will be. This is because capsaicin, the chemical that makes hot food spicy, is more concentrated in smaller peppers.
Serrano vs. Jalapeno
Jalapenos can be your best option as a substitute for serrano peppers. Jalapenos are easy to find in nearly all grocery stores whereas serranos are very common in Mexico, but may not be as easy to get in some parts of the U.S..
Both peppers look very similar. They’re both long and relatively skinny peppers that taper at the end and they’re most often dark green when purchased.
However, serranos are typically skinnier and slightly shorter than the average jalapeno.
Jalapenos are less spicy, but they have a similarly bright flavor. If you’ve tasted a jalapeno, you know what a serrano pepper will taste like.
The difference comes in the heat level. Serrano peppers can be up to three times as hot a jalapeno. If you like jalapenos but wish they had more heat, serrano peppers are the answer to your recipe dilemmas.
Handling tips
If you have sensitive skin or open wounds, always use gloves while handling chili peppers, especially ones that are particularly spicy. These are not as dangerous as habaneros, but dangerous enough that you need to avoid touching your eyes when you handle and/or cook with them.
Before using them in a recipe, rinse the peppers well and cut off the stem.
If you want to tone the heat down just a bit, you can remove the seeds and veins. However, the seeds are edible. These peppers can be eaten raw or simply chopped and added to dishes as desired.
Serranos don’t need to be peeled since the walls of the skin are very thin.
While usually used fresh, you can also dry serrano peppers. It’s not as common as other dried peppers because of the meatiness of the flesh. If you are looking for them in the store, they may be called balin, tipico or largo.

Can you add blended serrano peppers to green parole after the parole has already been made a day before?
Hi Sandra! If you do, we recommend heating the posole back up with the blended peppers over the stove so it can incorporate the flavor. I hope this helps!
I made the green Pozole in a huge pot and used 15 jalapeno peppers, but my pozole wasn’t spicy. Would I use serrano peppers for that? If so about how many would I use. I want it real spicy but not super hot.
Hi Sandra! Yes, you can add serranos to make it spicy. We suggest adding them 1-2 at a time and then tasting the sauce to make it to your liking.
Like most peppers, the heat range on the serranos I purchase vary greatly. I’ve had ones from the local grocery store that I can eat almost like bell peppers. The ones I get from the Supermercado are blazing hot. Thought I was putting 2 grocery store serranos in my last batch of salsa but turns out it was 2 from the Supermercado! Holy hellfire batman. Salsa was great but just at the limit of heat I can take. Good article.
