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. Itโ€™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. 

How to roast serrano peppers

Roasting serrano peppers is a common way to cook them. It’s super easy to do and adds another layer of rich smoky flavor! Here’s how to do it.

  1. Rub the peppers with oil.
  2. Roast under a broiler or over an open flame.
  3. Let the skin blister and char.

    I have been letting my serrano peppers turn red on the plant. They are so sweet and the heat is still there. I’ve been roasting them in the oven and then freezing them to use later.

    Hi, I bought some seronno peppers and want to stuff them with cream cheese and soppresotta, then cook on the grille in my pepper rack. What’s the best way to do this? Also how long would I grille them for?

    Can you add blended serrano peppers to green parole after the parole has already been made a day before?

    1. Ana @ Isabel Eats says:

      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!

  4. Sandra Wilson says:

    I made the green Pozole in a huge pot and used 15 jalapeno peppers, but my pozole wasnโ€™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.

    1. Ana @ Isabel Eats says:

      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.
