Step 1

Remove and discard the husks and rinse the tomatillos in cold water.

Step 2

Position an oven rack about 6 inches from the broiler. Preheat the oven to High broil (500F). Line a baking sheet with foil or lightly brush with oil.

Step 3

Cut the tomatillos in half and place cut side down in an even layer on the baking sheet. Scatter the onion and garlic around the tomatillos.

Step 4

Broil for 5 to 6 minutes or until the tomatillos are starting to char and turn black.

Step 5

In the container of a food processor or blender, combine the charred vegetables, cilantro, lime juice, jalapeño, and salt. Blend until finely chopped or desired consistency. Taste and add more salt if needed.

Step 6

Transfer to an airtight container and let the salsa sit for at least 1 hour before serving. Salsa can be refrigerated for up to 5 days.
