Begin by preheating your oven’s broiler and lining a large baking sheet with aluminum foil.
While the oven preheats, remove the husks from the tomatillos, rinse them off, and dry them with a paper towel or clean flour sack. Cut them in half and place the cut side down on your prepared baking pan.
Next, place the fresh garlic, onion, and jalapenos (cut side down) on the pan with the raw tomatillos.
Place the pan under your broiler and allow them to cook for 5-7 minutes until the skins of the tomatillos are slightly blackened.
Remove the pan from the oven and allow your ingredients to cool.
Now, place everything except the salt and pepper into a food processor and pulse until everything is finely chopped and mixed together.
Pour the salsa verde into a serving dish and season with salt and pepper, or place in an airtight container or glass jar to store in the refrigerator until you’re ready to use it.
