Total Time: 1 Hour
For Tomatillo Sauce
- 1 tablespoon olive oil
- 1 medium yellow onion, roughly chopped
- 3 medium cloves garlic, peeled and smashed with the side of a chef's knife
- 3/4 pound tomatillos, husks and stems removed, cut into 1-inch chunks
- 3 jalapeño chiles, seeded and roughly chopped
- 1 teaspoon sugar
- 3/4 teaspoon salt
- 1/4 teaspoon ground cumin
For the Filling
- 1 pound chicken tenderloins
- 2 teaspoons ground cumin
- 1-1/2 teaspoons smoked paprika
- 1 teaspoon salt
- 2 tablespoons olive oil
- 1 medium yellow onion, chopped
- 1/2 cup chopped fresh cilantro leaves
- 8 ounces (2 cups) shredded sharp cheddar cheese
For the Tortillas and Toppings
- 11 6-inch corn tortillas
- 2-1/2 tablespoons olive oil
- 3 ounces (3/4 cup) shredded sharp cheddar cheese
- Smoked paprika
- 3/4 cup sour cream
- 1 small heart of romaine lettuce (or 5-6 leaves), shredded
- 1 avocado diced
- 1 lime, sliced
For the Tomatillo Sauce
- Heat the oil in a medium saucepan over medium heat. Add the onions and garlic and cook, stirring occasionally, until softened, about 5 minutes. Add the tomatillos, jalapeños, sugar, salt, cumin and 1/3 cup water; bring to a simmer, then reduce the heat to medium-low and simmer until tomatillos are softened, about 8 minutes. Transfer the mixture to a blender and purée until completely smooth. Set aside.
For the Filling
- Place the chicken tenderloins in a medium bowl and sprinkle with the cumin, smoked paprika and salt. Toss with tongs until the chicken is evenly coated with the spice blend.
- Heat the oil in a large nonstick sauté pan until shimmering but not smoking. Add the chicken and cook until just done, about 2 minutes per side; transfer to a plate to cool. Do not rinse the pan. Add the onions and reduce the heat to medium. Cook, stirring occasionally, until soft, about 5 minutes. Remove the pan from the heat.
- Once the chicken is cool enough to handle, shred it into bite-sized pieces. (All tenderloins have a tough tendon running through them; just remove it.) Add the shredded chicken to the pan with the onions, along with the chopped cilantro and shredded cheese.
- Preheat oven to 400 degrees.
- Spread 3/4 cup of the tomatillo sauce on the bottom of a 9 x 13-inch baking dish.
- Pour the oil into a small bowl or ramekin. Using a pastry brush (or your hands), brush both sides of each tortilla with oil, then stack them on a plate and microwave until hot and steamy, 1-1/2 - 2 minutes. This makes them pliable.
- Spoon about 1/3 cup of the filling down the center of each tortilla. Roll each tortilla tightly and place side by side in the baking dish, seam side down.
- Pour the remaining chili sauce over the top, and use the back of a spoon to spread evenly over each tortilla. Sprinkle the cheese down the center of the enchiladas. Bake until hot and bubbling, 15-20 minutes. Sprinkle the smoked paprika down the center of the enchiladas and serve immediately with sour cream, lettuce, avocado and lime wedges.
