Preheat oven to 450 degrees. Remove the husks from the tomatillos. Rinse under warm water well and wipe clean. Cut the tomatillos in half and place into a baking pan. Roast for 20 minutes until they are tender.
Remove and set aside to cool. Add all ingredients to a food processor and pulse for 1-2 minutes until smooth and creamy.
Let cool, adjust salt and pepper and serve as needed.
Notes
If you haven't used tomatillos, make sure you remove the husk and then give them a quick wash as they can be sticky.
