Chicken Enchilada Casserole

This dish is quite spicy, but so satisfying. The original recipe calls for traditional enchiladas (rolled and placed side-by-side in a dish), but I find it is much easier to make a casserole. My changes are listed below; click here for the original recipe.

Chicken Enchilada Casserole
Adapted from Tyler Florence's Chicken Enchiladas

• 3 tablespoons vegetable oil
• 1 1/2 pounds skinless boneless chicken breast
• Salt and pepper
• 2 teaspoons cumin powder
• 2 teaspoons garlic powder
• 1 teaspoon Mexican Spice Blend
• 1 red onion, chopped
• 2 cloves garlic, minced
• 1 cup frozen corn, thawed
• 5 canned whole green chiles, seeded and coarsely chopped
• 4 canned chipotle chiles, seeded and minced
• 1 (28-ounce) can diced tomatoes
• 1/2 teaspoon all-purpose flour
• 18 corn tortillas
• 1 can enchilada sauce
• 2 cups shredded Cheddar and Jack cheeses
• Garnishes: chopped cilantro leaves, chopped scallions, sour cream, chopped tomatoes

1. Coat large saute pan with oil. Season chicken with salt and pepper. Brown chicken over medium heat, allow 7 minutes each side or until no longer pink. Sprinkle chicken with cumin, garlic powder and Mexican spices before turning. Remove chicken to a platter, allow to cool. Saute onion and garlic in chicken drippings until tender. Add corn and chiles. Stir well to combine. Add canned tomatoes, saute 1 minute. Pull chicken breasts apart by hand into shredded strips. Add shredded chicken to saute pan, combine with vegetables. Dust the mixture with flour to help set.
2. Ladle a small amount of enchilada sauce into the bottom of a 9 x 13 glass baking dish. Layer six corn tortillas on top of the sauce. Spread half of the chicken mixture over the tortillas and top with 3/4 C cheese. Repeat layering -- six more corn tortillas, remaining chicken, 3/4 C cheese. Top with the remaining six tortillas. Pour the enchilada sauce over the top, and sprinkle remaining 1/2 C cheese over the top.
3. Bake for 20 minutes in a preheated 350 degree F oven until cheese melts. Serve with sour cream.
