Introduction to Guajillo Peppers
If you're a spice lover, chances are you've heard of guajillo peppers. These long, reddish-brown chilies are a staple in Mexican cuisine, known for their smoky, tangy flavor and moderate heat. But here's the burning question: Are guajillo peppers hot? Let's dive into the spicy details.

Originating from Mexico, guajillo peppers are typically dried after harvest. They have a slightly wrinkled texture and are often used in salsas, moles, and stews. While they’re not as fiery as habaneros or ghost peppers, they still pack a noticeable punch that can add depth and warmth to your dishes.
How Hot Are Guajillo Peppers?
The Scoville Heat Unit (SHU) scale measures how hot a pepper is. For context, bell peppers are at 0 SHU, while jalapeños range from 2,500 to 8,000 SHU. So where do guajillo peppers fall on this scale?
Guajillo peppers typically measure between 2,500 to 5,000 SHU, placing them in the mild to medium heat range. This means they’re not going to burn your mouth off, but they will give your tongue a little tingling sensation. If you're new to spicy foods, you might find them a bit too much—but if you're a seasoned heat enthusiast, they’re perfect for adding some kick without overwhelming your palate.

One thing to note is that the heat level can vary depending on factors like growing conditions, ripeness, and how the pepper is prepared. Dried guajillos tend to be slightly hotter than fresh ones because the drying process concentrates the capsaicin, the compound responsible for the heat.
Guajillo vs. Other Common Peppers
To better understand how hot guajillo peppers really are, let’s compare them to some other popular peppers:
Pepper | SHU Range | Heat Level |
---|---|---|
Guajillo | 2,500 - 5,000 | Mild to Medium |
Jalapeño | 2,500 - 8,000 | Mild to Medium |
Serrano | 10,000 - 23,000 | Medium to Hot |
Habanero | 100,000 - 350,000 | Very Hot |
Ghost Pepper | 1,000,000+ | Extremely Hot |

As you can see, guajillo peppers are relatively mild compared to many other chili varieties. They share a similar heat range with jalapeños, which makes them great for those who want some heat without the intense burn of hotter peppers.
Using Guajillo Peppers in Cooking
Now that we’ve established that guajillo peppers are hot, let’s talk about how to use them in your kitchen. Their unique flavor—smoky, slightly sweet, and tangy—makes them a versatile ingredient.
Top Tips for Cooking with Guajillo Peppers

- Use in salsas and moles: Guajillo peppers are a key ingredient in traditional Mexican salsas and moles, adding both heat and complexity.
