What is Guajillo Sauce?

Guajillo sauce is made from dried guajillo peppers, which are native to Mexico. These slender, reddish-brown chilies are known for their smoky depth and earthy undertones.

Dried guajillo peppers

When turned into sauce, guajillo peppers are rehydrated, blended with spices like garlic, vinegar, and sometimes tomatoes, and then simmered to create a rich, complex base used in countless dishes — from enchiladas to marinades.

As you can see, guajillo sauce falls comfortably on the mild-to-medium side of the spice spectrum. It’s spicier than a bell pepper (which has zero SHU), but nowhere near the nuclear levels of habaneros or ghost peppers.

If you're new to spicy food or prefer your meals more on the mellow side, guajillo sauce is a great option. You’ll get that zesty kick without the full-blown inferno in your mouth.

Flavor Profile: More Than Just Heat

Uses in Cooking: When and How to Use It

Guajillo sauce might be mild, but don’t underestimate its power in the kitchen. Here are some delicious ways to use it:

Tacos & Enchiladas

Slather it on tacos al pastor or pour it over cheesy enchiladas before baking. It brings everything together with a soft, smoky warmth.

Mix guajillo sauce with lime juice, garlic, and olive oil for a killer chicken or pork marinade. Let sit for a few hours and grill for an instant fiesta.
