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.
