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.

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.
How Spicy Is Guajillo Sauce?
So, finally, the moment you’ve all been waiting for: how hot is guajillo sauce?
Pepper / Sauce | Scoville Heat Units (SHU) |
---|---|
Guajillo Pepper | 2,500 – 5,000 SHU |
Guajillo Sauce | Varies by brand, typically around 1,500 – 4,000 SHU |
Jalapeño Pepper | 2,500 – 8,000 SHU |
Hatch Green Chile | 1,000 – 10,000 SHU |
Habanero Pepper | 100,000 – 350,000 SHU |
Ghost Pepper | Over 1 million SHU |

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
Now here’s the real secret: guajillo sauce isn’t just about the heat. Its flavor is a beautiful symphony of:
- Smoky sweetness
- Mild earthiness
- Teeny bit of tang
- Faint berry-like notes
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.
Marinades
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.
Stews & Braises
Add a splash to slow-cooked stews or braised meats. It enhances richness and adds a subtle layer of spice that won’t overpower the main ingredients.
Eggs
Spice up breakfast with a drizzle over scrambled eggs or shakshuka. Yes, really!
DIY Hot Sauces & Salsas
Use it as a base and blend with other hotter peppers (like chipotle or serrano) if you want to crank up the heat.
