3 cups
shredded pepper Jack or Monterey Jack cheese
12 (6 to 8-inch)
flour tortillas
Vegetable oil, for frying
Method
Make the shredded chicken: Set a cooling rack inside a rimmed sheet pan. Bring a large pot of water to a boil over high heat. Add the onion, chicken, and 2 tablespoons of the salt. Reduce the heat to medium, cover, and cook until chicken reaches 165°F on an instant-read thermometer, about 20 minutes. Using a slotted spoon, transfer the chicken to a plate. Let cool slightly, then shred with two forks.
Make the flauta filling: In a large bowl, combine the shredded chicken, the remaining ½ teaspoon salt, the cumin, chili powder, garlic powder, chipotle pepper, adobo sauce, lime juice, sour cream, and cheese.
Assemble the flautas: Add ⅓ cup of the chicken filling to the center of each tortilla, spreading it out slightly. Roll the tortillas tightly and place them seam-side down.
Fry: Pour 1 inch of oil into a large skillet and heat over medium-high heat. Once the oil is glistening, carefully add the flautas seam-side down and cook until golden brown, about 2 minutes per side. Transfer the flautas to the cooling rack to cool for 1 to 2 minutes before serving.
