What is salsa verde?

Salsa verde is a Mexican green sauce that, unlike salsa roja, is most commonly made with tomatillos instead of tomatoes.

Depending on the recipe, it may have different types of chile peppers, cilantro, onion, garlic, and spices.

Salsas can be made by boiling the ingredients, roasting the ingredients (either in a pan or the oven), and even be made raw. 

You get different flavors for each method, and this recipe boils the ingredients.

The tart, tangy flavor of the tomatillos pairs wonderfully with the spicy serrano peppers, garlic, and fresh onion and cilantro that’s added at the end.

📍The full recipe with exact ingredient amounts and instructions is on the recipe card at the bottom of the post.

How hot are serrano peppers?

To identify how spicy chile peppers are, their capsaicin (a chemical compound) is measured in units called Scoville Heat Units, or SHU.

Serrano chile peppers (shown below) have about 23,000 SHU.  

In comparison, jalapenos have about 5,000 SHU and habanero peppers have about 350,000 SHU.

The cilantro and minced onion is added in at the end, as it gives the salsa a great texture.  

If for some reason, you are averse to cilantro, you can easily set some salsa aside before adding it in.

How long is homemade salsa good for?

Store leftover salsa in an air-tight container in the refrigerator for up to 4-5 days.

Is Serrano Salsa spicy?

Yes, the recipe is spicy as written.  If you would like to make a less spicy version, simply reduce the amount of serrano peppers. 

I find the spice level to be a nice addition to the tang from the tomatillos and the freshness from the onion and cilantro.

NOTES:

  • Make sure you wash the tomatillos after you peel off their husks.  Often times there is dirt or debris stuck to the sticky tomatillos.
  • Cilantro seems to be a polarizing ingredient – people either love it or hate it.  For this reason, I don’t give an exact amount in the recipe.  “Handful” refers to how much I use when making it, but add some in small amounts until you reach your desired salsa verde.

Equipment

  • 1 sauce pan
  • food processor or blender

Ingredients
  

  • 1 pound tomatillos husks removed and washed
  • 6 serrano peppers add less to make more mild
  • 1 garlic clove
  • water to cover the produce
  • 1/4 cup finely diced onion yellow or white
  • chopped cilantro to taste
  • 1/2 teaspoon sea salt
  • black pepper to taste

Instructions
 

  • After removing the husks and washing the tomatillos, add them to a sauce pan with the serrano peppers and garlic (save the onion and cilantro for later). Add enough water to cover everything in the pan.
  • Bring the water to a boil and continue boiling for about 5 minutes. You will see the tomatillos turn from bright green to a dull, yellowy green. Add the veggies from the sauce pan along with 3 tablespoons of water, salt, and pepper to a blender or food processor. Blend until smooth.
  • Pour the salsa into a bowl and then stir in the chopped onion and cilantro. Cilantro is not for everyone, so add it in small amounts until you get it where you want. Enjoy!
