Medium |  Servings: 8  |  Ready In: 10 minutes |  Yield: 2 cups

Based on a classic Oaxacan recipe, charred tomatillos, garlic, and serrano pepper give a different twist on guacamole.  Use this to top oil-free Baked Tostados, vegan Stewed Black Beans, or plant-based vegan Black Bean Cakes.


  • 4 medium tomatillos
  • 2 cloves garlic, unpeeled
  • 1 serrano pepper*
  • ¼ cup fresh cilantro, roughly chopped
  • 1 large avocado
  • ¼ teaspoon salt

How it’s Done

To make the Tomatillo Serrano Guacamole:  Preheat a small non-stick pan over medium-high heat.  If possible, use cast iron or even a griddle.  Husk, rinse, and halve the tomatillos.  Halve the serrano pepper.   Lay the tomatillos in cut-side down.  Lay in the unpeeled garlic and serrano pepper.  Cook until lightly charred, about 3-4 minutes.  Flip and char the second side, another 2-3 minutes.  Remove the garlic from the peel.  Place the tomatillos, garlic, and serrano in a blender.  Set aside for a few minutes to let cool.

Once the tomatillos have cooled, add the cilantro, avocado, salt, and ¼ cup of water.  Puree.  You may need more water (up to ¼ cup) to get a thick, yet smooth, consistency.  Enjoy immediately or refrigerate for later.

Yield: 2 cups

Chef Katie’s Tips:

Serrano Substitutions:  If you can’t find serrano pepper, you can also use half of a jalapeno.  If you want less spice, simply omit or use ¼ of a green bell pepper.

Citric Acid: If you’re not enjoying this guacamole right away, add 1/4 teaspoon citric acid during the blending.  This will help preserve the bright green color and prevent the brown caused from oxidation.

Homage to Chef Rick Bayless: This recipe is based off a Chef Rick Bayless’s recipe.  Bayless has done incredible work educating fellow chefs and the population about the beautiful, authentic cuisine of Mexico.
