What Exactly Is a Guajillo Pepper?

Dried Guajillo Peppers on Counter

Guajillo peppers (pronounced wah-HEE-yoh) are dried versions of the Miranda chili, a medium-heat chili native to Mexico. Once harvested, these chilies are sun-dried until they become leathery and deep red in color.

You’ll often find them used in salsas, moles, marinades, and sauces where depth of flavor is key. Unlike some other chilies, guajillos aren’t just about heat — they bring complexity and richness to the table. Literally.

How Hot Are Guajillo Peppers? (Spoiler: Not Scary, Just Sexy)

Spice Level Chart with Guajillo Pepper

Let’s talk numbers. Guajillo peppers range from 2,500 to 5,000 SHU (Scoville Heat Units). To put that into perspective:

Pepper Heat Level (SHU)
Guajillo 2,500–5,000
Jalapeño 2,500–8,000
Ancho 1,000–2,000
Pasilla 1,000–2,500

So while guajillos can definitely bring the heat, they’re more “spice with sophistication” than “burn your mouth off.” Think of them as the James Bond of chilies — refined, complex, and always in control.

Want to Grow Your Own Guajillos? Here’s How!

Chili Plants Growing in Garden

Guajillos start their lives as fresh Mirandas — long, pointed chilies that turn bright red when mature. If you live in a warm climate or have a sunny indoor spot, you can grow your own:

  • Start from seeds indoors 8–10 weeks before the last frost.
  • Transplant outside once soil warms up (above 60°F/15°C).
  • Water regularly but avoid soggy soil.
  • Harvest when fully red, then lay out in the sun to dry.

Fun Facts That’ll Make You the Life of the Party
