How to Make Guajillo Sauce

This sauce is all about toasting and rehydrating the chile for the sauce. If you’re using whole spices, check the recipe card at the bottom of the post for more detailed instructions on how to incorporate them into the sauce.

  • Toast the chiles. Heat a large pan and toast the chiles on all sides. Don’t let them burn.
  • Rehydrate them. Bring a pot of water to a boil and add the chiles. Let them sit in the water until completely softened.
  • Blend the sauce. Strain the chiles and reserve some of the liquid. Blend the onion, garlic, oregano, cumin, guajillos, salt, pepper, and reserved liquid until smooth.
  • Simmer it. Heat the oil in a pot and add the sauce. Stir and let it cook for 15 minutes.
  • Serve. Remove the pot from the heat and serve the sauce with your favorite Mexican recipes.

Tips for Success

These tips will help you successfully make any chile-based sauce.

  • Reduce the heat. Add 3 to 4 Roma tomatoes to the recipe in order to reduce the heat. You can also bring down the number of guajillos to 5 to 7 for a milder sauce.
  • Wear gloves. Using plastic gloves to seed and stem the chilis will help you avoid teary eyes later when you accidentally rub your eyes or scratch your nose.
  • Strain the sauce. In case you used whole peppercorns or cumin seeds and want to make sure your sauce is super smooth, strain it into the pot before simmering it.
  • Pick fresh chilis. Even though the chiles are dried, some are fresher than others. The best dried chilis should be slightly bendy and not crack when bent.

Common Questions

The answers to these FAQs will help you figure out whether or not to reduce the amount of chiles in the sauce so that it’s not overly spicy.

What are guajillo peppers?

Guajillo peppers are the dried version of fresh Mirasol chiles. They’ve got a bright, fruity flavor with a mild-medium heat level and are typically used as a base for many Mexican dishes.

Are guajillo chilis spicy?

Not really, but it does depend on your tolerance to heat. They have 2,500-5,000 Scoville Heat Units, making them spicier than an anaheim, but less spicy than chilis like habaneros, cayenne, and serrano peppers.

Is guajillo hotter than jalapeno?

No. The hottest guajillo is as spicy as the mildest jalapeño, but according to the Scoville heat scale they can’t be spicier.

Proper Storage

Once fully cooled, refrigerate leftover guajillo sauce in an airtight container for up to 5 days. Keep it away from heat and sunlight when on the counter for reheating or serving.

To reheat it, pop it into the microwave for up to a minute or until warm. You can also heat it in a small pot over medium heat for 6-9 minutes. You can also serve it at room temperature or chilled if you’re using it as an appetizer with chips or a topping for tacos.

Can I Freeze This?

Yes! Freeze it in 1/2-1 cup portions so that you don’t have to worry about defrosting a huge batch of salsa later. Thaw overnight in the fridge and then reheat or serve as usual.

Prep Time10 minutes
Cook Time20 minutes
Soaking Time15 minutes
Total Time45 minutes

Ingredients

  • 10 dried guajillo chiles, seeds and stems removed
  • 4 cups water
  • ½ small onion
  • 3 garlic cloves
  • 1 tablespoon Mexican oregano
  • 1 teaspoon cumin
  • 1 teaspoon black pepper
  • 1 teaspoon salt
  • 1 tablespoon oil

Instructions 

  • Heat a pan and toast the peppers on all sides. They may get a few dark spots, but you don’t want them to blacken too much or they may become bitter.
  • Heat 4 cups of water to boiling. Once boiling, turn off the stove. Place the toasted chilis in the hot water and let sit for 15 minutes, until they are softened. 
  • Remove the chilis from the water (reserving 1 cup of the water the chiles cooked in) and place the chiles in a blender, or food processor. Add the remaining cup of reserved chili water, onion, garlic, Mexican oregano, cumin, pepper, and salt. Blend until smooth. (If using whole peppercorns and whole cumin seeds, you will need to grind them with a mortar and pestle or spice grinder before adding them to the food processor.)
  • Heat the oil in a deep pan over medium heat and pour the sauce into the pan. Bring sauce to a simmer and cook for 15 minutes, stirring often. 
  • Use the sauce, as desired, or in tamales, birria, soups or chiliquiles.
