The Ultimate Guide to Guajillo Peppers: From Scoville to Salsa
Ever wondered what guajillo peppers are and how to use them? As a chef and travel lover passionate about global flavors, I'm sharing my expert tips—inspired by our family friend Richard’s Mexican adventures—to help you master this essential Mexican chile.
From My Journal: Culinary Inspiration from Friends
My passion for guajillo peppers was sparked by Richard, a childhood friend from England who visited Mexico in 2018. He brought back a mole recipe from a Puebla market, and as a professionally trained chef, I was fascinated. We spent countless sessions in the kitchen deconstructing and adapting it. This experience, blending his travel stories with my culinary techniques, is what inspires me to explore global flavors and share them with you.

What Are Guajillo Peppers?
The guajillo (pronounced gwah-HEE-yoh) is the dried form of the Mirasol chile. Its name, meaning "looking at the sun" in Spanish, reflects its upward growth when fresh. Once dried, it transforms into a flavorful chile vital to Mexican dishes. It's part of the famed "Holy Trinity" of Mexican chiles, along with the Ancho and Pasilla, which together form the flavor base for countless mole sauces and stews. Learn more about chile varieties at our Chile Poblano Guide.
How to Select and Store Guajillo Chiles
When you're at the grocery store, look for chiles that are pliable and flexible; if they are brittle and crack easily, they are old and have lost much of their flavor. They should have a deep, reddish-brown color and a slight sheen. Avoid any that look dusty or have blemishes. To store them, keep them in an airtight container in a cool, dark pantry. They'll retain their flavor for up to two years.
Flavor & Heat Profile
The guajillo’s appeal lies in its nuanced flavor, not just its heat. It offers a sweet, fruity taste with notes of berries and green tea, balanced by a light smokiness. Its heat level is a mild-to-medium **2,500-5,000 on the Scoville Scale (SHU)**, similar to a mild jalapeño. This makes it incredibly versatile for adding depth to dishes without making them overwhelmingly spicy.

How to Cook with Guajillo Peppers (Recipe for Guajillo Paste)
This simple paste is the foundation for countless recipes, from my Guajillo Beef Tacos to rich sauces and stews. Unlocking the guajillo’s flavor is easy with these key steps.
Ingredients
- 6-8 dried guajillo chiles
- 2 cloves garlic, unpeeled
- 1/2 white onion, cut into wedges
- 2 cups hot water
- 1/2 teaspoon salt
Instructions
- Toast the Chiles: Wipe the chiles clean. In a dry cast iron skillet over medium heat, toast the chiles for 30-60 seconds per side until they become fragrant and slightly change color. Add the unpeeled garlic and onion wedges and toast for another 2-3 minutes until lightly charred.
- Seed and Stem: Let the chiles cool for a minute. Remove the stems and slice them open to scrape out the seeds and veins. The garlic skin should peel off easily.
- Rehydrate: Place the toasted chiles, onion, and garlic in a bowl and cover with 2 cups of hot water. Let them soak for 20-30 minutes until they are soft and pliable.
- Blend: Transfer the chiles, onion, garlic, and about 1 cup of the soaking liquid to a high-speed blender. Add the salt and blend until completely smooth. Add more soaking liquid if needed to reach a thick, sauce-like consistency.
