In a blender, combine the tomatillos, cilantro, serrano, onion and garlic and puree until smooth. In a medium saucepan, heat the vegetable oil. Add the salsa, season with salt and pepper and bring to a boil. Simmer over moderate heat until reduced to 2 1/2 cups, about 10 minutes. Let cool.
The salsa can be refrigerated for up to 5 days.
