Ingredients

  • 1 1/2 tbsp. olive oil tips & tricks
  • 2 large skinless, boneless chicken breasts, cubed
  • ground Himalayan pink salt, to taste and divided
  • freshly ground black pepper (I always use mixed peppercorns), to taste and divided
  • 1 tbsp. butter
  • 1 cup yellow onions, chopped
  • 1/2 cup celery, chopped tips & tricks
  • 1/2 cup red peppers, chopped
  • 1/2 cup poblano peppers, chopped
  • 2 large cloves garlic, pressed
  • 3 tbsp. unbleached all-purpose flour
  • 1/2 cup low-sodium chicken broth
  • 1 1/2 cups heavy cream
  • 1 tbsp. Old El Paso Taco seasoning see Recipe
  • 1/2 tbsp. ground cumin
  • 1 tsp. smoked paprika
  • 1 tsp. dried thyme leaves
  • 1 lb. green beans, ends trimmed and blanched tips & tricks
  • 2 cups tortilla chips, broken into smaller pieces *optional
  • 2 cups sharp Cheddar cheese, grated

Directions

  • Preheat oven to 350ºF and lightly grease a 9 x 13-inch baking dish; set aside.
  • In a large skillet over medium heat, add oil and when hot, add chicken cubes; season with salt and black pepper. Sauté until no longer pink, about 4 minutes.
  • Using a slotted spoon, transfer the cubes to a bowl and set aside.
  • Melt butter in the skillet before adding onions and celery; season with salt. Sauté for 2 minutes.
  • Add red and poblano peppers; sauté for 2 minutes.
  • Add garlic and sauté for just 1 minute.
  • Coat the ingredients with flour and cook for 1:30 minutes. Pour in broth and stir constantly until the mixture thickens and becomes pasty.
  • Add heavy cream and seasonings; mix well. Add blanched green beans and return chicken with any accumulated juices. Stir to combine.
  • Pour the mixture into the prepared baking dish. Top with tortilla chips and grated cheese.
  • Cover with foil lightly greased and transfer to the preheated oven; bake for 15 minutes.
  • Uncover and bake until the cheese is melted and the top is golden brown, about 10 minutes.
  • Remove from the heat and let it rest for 10 to 15 minutes before serving.
