2 pounds tomatillos, husked and rinsed (10-14, depending on the size) or 3 cups purchased tomatillo salsa or salsa verde
1 medium white onion, peeled and cut into 8 wedges
2–3 jalapeño peppers, stem end cut off. If you don’t like a lot of heat, slice them in half lengthwise, and remove the seeds and white pith
1 tablespoon olive oil
1 cup roughly chopped cilantro leaves and tender stems (remove thick stems), plus more cilantro leaves for garnishing
I tablespoon finely chopped garlic (2-3 large cloves)
1/2 teaspoon kosher salt
For The Enchiladas
12 6-inch soft corn tortillas
3 ½ cups shredded cooked chicken*
2 tablespoon sour cream, plus more for garnishing
4 ounces Cotija cheese, grated
6 ounces grated cheddar cheese
1/2 small red onion, peeled, cut in half through the root and cut crosswise into very thin slices.
Make the salsa verde: Preheat oven to Broil. In a large bowl toss tomatillos, onion and jalapeños with 1 tablespoon olive oil. Lay them out on a rimmed baking sheet and roast for 7 minutes or until there are some brown spots on the tomatillos. Lower temp to 400F. Turn the tomatillos over with tongs. Cook for another 5-7 minutes, until the tomatillos are softened. Transfer the roasted vegetables to the bowl of a food processor. Add cilantro, garlic and salt. Pulse several times until you get your preferred consistency. I like my salsa a bit chunky. You should have about 4 cups of salsa.
Make the Enchiladas Set oven to 350F. Spread 1 cup of salsa into the bottom of a large casserole or baking dish. In a bowl mix shredded chicken with 1 cup of salsa, 2 tablespoons of sour cream, and 4 ounces Cotija cheese. Set aside while you soften the tortillas.
Soften the tortillas: If your tortillas are soft and pliable you can skip this step. Heat a skillet (preferably cast iron) over medium high heat. Place a tortilla in the skillet, pressing it against the pan with a spatula, for about 10 seconds per side. Transfer warm tortilla to a clean dish towel and fold towel over it to keep it warm. Repeat with all of the tortillas, continuing to stack them inside the dish towel.
Roll the Enchiladas: Put 1/4 cup of the chicken mixture on one end of a tortilla, roll it up tight and place it seam-side down in the baking dish. Repeat with all of the tortillas. Spoon a cup of salsa over the tops of the enchiladas, using the back of a spoon to spread the salsa over all exposed surfaces. Sprinkle grated cheddar cheese on top. Bake for 15 to 20 minutes, until cheese is melted and enchiladas are heated through.
Serve with sour cream, red onion, cilantro leaves and remaining salsa
