Ingredients

Poblano Cream Sauce

  • 3 roasted poblanos, seeds removed, peeled
  • 2 roasted jalapenos, seeds removed
  • 1 medium onion, sliced into rings
  • 15 ounce green enchilada sauce
  • 1 cup heavy cream
  • ¼ cup chicken broth
  • 1 teaspoon chicken bouillon
  • ½ teaspoon red pepper flakes

Instructions

Grilled Chicken

  • Heat the grill to 350 degrees.
  • Cut chicken breasts in half lengthwise, pat dry with paper towels, and rub olive oil on both sides of the chicken and sprinkle both sides with seasoning.
  • Grill chicken approximately 3-5 minutes on each side or until the internal temperature reaches 165 degrees,
  • Remove chicken from the grill and set aside.

Creamy Poblano Sauce

  • Wash and dry the peppers.
  • Rub the peppers and onions with olive oil and place on the hot grill.
  • Let poblano peppers cook until blistered and charred on each side, and grill the jalapeños and onions for a few minutes until the jalapeños and onions have softened a bit.
  • Remove from the grill and place the poblanos in a gallon size baggie, or a bowl, and cover with plastic wrap. Let steam for 10 minutes.
  • Remove from the baggie/bowl and peel the skin off each pepper.
  • Cut stems off of the poblano and jalapeno peppers, remove seeds, and place into a vitamix or a blender.
  • Add grilled onions, enchilada sauce, heavy cream, chicken broth, chicken bouillon, and red pepper flakes into the vitamix and blend until creamy.

Putting the Enchiladas Together

  • Shred grilled chicken and add to a bowl.
  • Pour 1 cup of sauce into the bowl with the shredded chicken, add the spinach, and stir to combine.
  • Heat tortillas in a pan over medium heat.
  • Preheat the oven to 375 degrees.
  • Spray a 9x13 deep baking dish with non-stick cooking spray.
  • Pour 1 cup of creamy poblano sauce into the bottom of the baking dish and top with a layer of corn tortillas.
  • Spread a thin layer of sour cream over tortillas.
  • Next, add shredded chicken in an even layer on top of sour cream and then top with cheese and more sauce.
  • Repeat the layers, ending with sauce and shredded cheese.
  • Cover with aluminum oil and bake in the oven for 25 minutes.
  • Remove foil and bake for an additional 10 minutes or until the cheese has melted throughout.

Notes

  • Pat the chicken breasts as dry as possible to ensure the seasonings adhere readily to the meat.
  • Rub your grates with oil before preheating the grill to prevent sticking.
  • Refrigerate your onions for about 30 minutes before slicing them to avoid stinging eyes.
  • Wash your hands and NEVER touch your face when handling hot peppers.
  • Be sure your baggie is completely closed or your bowl is tightly covered with plastic wrap to ensure the poblano peppers are steamed well before peeling.
