🌶️ What is chile de árbol?

Chile de árbol (Spanish for “tree chili”) is the name given to this slender pepper, referring to the long wood-like stem. It is also known by other names like rat’s tail chile.

Originally from the Mexican states of Jalisco and Oaxaca, you can now find this spicy pepper grown all over the world.

Chiles de árbol are typically about 2-3 inches long and change from green to bright red in color as they ripen.

Unlike most chiles that take on other names once dried, chile de árbol is the name given to the fresh, dried, and powdered form of this pepper. Once dried, arbol peppers can be toasted to impart unique flavors in a wide variety of recipes.

🍴 Flavor profile

The flavor of a dried chile de árbol is smoky, nutty, and slightly grassy. Again, all of these base tasting notes are accentuated by toasting the peppers.

Chiles de árbol are typically utilized in recipes like salsa to impart more spice. They also make a great addition to sweet recipes, such as chile-infused brownies or cakes.

🔥 Spice level

Chile de árbol packs some serious heat, coming in at 15,000 to 30,000 Scoville Heat Units (SHU) on the Scoville Scale. However, peppers vary greatly in their spiciness. There have even been reports of arbol chiles reaching 65,000 SHU!

For a point of reference, a typical arbol chile is about 3-6 times hotter than your average jalapeño pepper, or slightly milder than cayenne pepper.

🧑‍⚕️ Health benefits

In such a small package, arbol chiles hold a plethora of health benefits. They contain large amounts of vitamin A and vitamin C, both of which are important for eye and skin health.

Chiles de árbol also contain minerals like calcium and iron, making them a spicy way to strengthen your bones.

In addition to all these health benefits, arbol chiles contain a special compound, capsaicin, which is helpful in lowering blood pressure and treating inflammation!

🧑‍🍳 Cooking with arbol chiles

Chile de arbol peppers are a great way to impart spice to both sweet and savory dishes. Since fresh arbol chiles are hard to come by, you generally need to rehydrate the dried variety for your recipes.

Arbol chiles work well in soups, stews, chilis, salsas, and hot sauces. You can even try adding them to chamoy sauce for a kick of heat. If preferred, they can be ground up into chile flakes, then added to recipes the same way as cayenne powder.

🌡️ Storage

Store your dried arbol chiles in a cool, dark space (like a cupboard or pantry) to ensure the flavors last longer. We prefer glass containers to keep the moisture levels better controlled, but just make sure whatever you use has a seal.

If you don’t have space in your cupboards, it’s best to use an opaque container for storage since light degrades chiles rather quickly.

💰 Buying guide

The chile de árbol is essential in a well-rounded Mexican kitchen arsenal. It’s easy to store, so make sure you always keep it on hand.

What to look for

Arbol chiles should be dry yet still pliable. If they are cracked and brittle, it typically means the flavors will be subdued.

If your arbol peppers are overly soft or damp, they’ve likely come in contact with too much moisture. It’s best to avoid these ones too.

Where to buy

Chiles de árbol should be available in most Mexican markets or Latin American food stores. There’s a good chance you’ll be able to find them at larger grocery chains as well — check in the spice or international aisles.

If you don’t have any of those options available to you, you can always order arbol chiles online.

♻️ Arbol chile substitutions

Arbol chiles don’t have an extremely complex flavor profile like some of the milder chiles, making them easier to substitute. The best choices include:

  1. Chile piquin: With the exact same heat level, piquin chiles (or chiles Japones) are a great alternative to arbol peppers — although they don’t have quite as much depth of flavor.
  2. Cayenne pepper: Similar in appearance, but almost double the heat level, cayenne peppers are a good choice if you want a spicier alternative to arbol chiles.
  3. Red pepper flakes: Crushed red pepper ranges from 15,000-30,000 SHU, so they are another good substitute for chile de árbol.

Why are my arbol chiles bitter?

An easy mistake to make when dry-toasting arbol peppers is to burn them. When chiles burn, they impart bitter flavors to the dish they’re in. If you catch this before adding them to the rest of the recipe, it’s best to start over again.

Can I dehydrate my own arbol chiles?

Since arbol chiles are grown commercially for drying purposes, it may be a challenge to find fresh ones. But if you do, you can absolutely make your own dried peppers in a dehydrator, oven, or under the sun.

Are arbol chiles smoked?

Although chiles de árbol have hints of smokiness, they do not undergo an actual smoking process. If that’s what you’re looking for, morita chiles might be better suited for your needs.

    1. Hey Mike!

      You won’t find a ton of fresh chiles de árbol in Mexican cuisine, but you can use them fresh or roast them to make salsa (like you would serranos or jalapeños). Alternatively, you can let them ripen to red, then dehydrate them! They are very flavorful this way.

    These chilis are like a game of Russia roulette. If you get a seed it’s game over for you 🌵 🔥.

      1. Are these chillies not as hot when you take the seeds out? I’m looking for a good flavor not so much heat.

        1. Hi Donna,

          Arbol chiles are still quite hot, even without the seeds. If you are looking for a chile with more flavor and less heat, you may want to try ancho, guajillo, or cascabel. We have guides for all of those as well. Hope that helps!
