Preheat oven to 375°
Spray a 9 x 13 baking dish with non-stick cooking spray and set aside.
In a medium frying pan, add corn and heat on medium high.
Sauté corn until kernels have turned golden and start to blacken. Remove from heat and set aside.
In a small pan, heat oil over medium low heat.
Once oil is hot, gently add a tortilla to the oil and fry for 15 seconds.
Flip tortilla over and fry for an additional 15 seconds. Remove from the oil and drain on a plate lined with paper towels to absorb the excess oil.
Repeat the process and cook the remaining tortillas.
Chicken Filling
In a medium bowl, add shredded chicken, roasted corn, chipotle peppers, sour cream, Cotija cheese, tajin, and cumin. Stir to combine.
Pour 1⁄2 cup of enchilada sauce into the bottom of the prepared pan.
Add about 3 tablespoons of chicken filling to each tortilla and top with shredded cheese.
Roll tightly and place seam side down in the prepared pan.
Repeat with the remaining tortillas and chicken filling.
Spoon remaining red sauce over enchiladas.
Sprinkle with remaining shredded cheese
Bake at 375 for 18 minutes, then increase heat to 425 for an additional 5 minutes to brown the cheese.
Remove from the oven and cool slightly before serving.
Optional, garnish with Cotija cheese, chopped cilantro, and sour cream, if desired.
