Ingredients:
- 3 Tbsp Neutral Oil (e.g., Canola or Vegetable)
- 3 Tbsp All-Purpose Flour
- 3 Tbsp Mild Chili Powder
- 1 tsp Ground Cumin
- 1 tsp Dried Oregano (Mexican preferred)
- ½ tsp Garlic Powder
- 1 tsp Salt
- 4 cups Low-Sodium Chicken Broth (warm)
- 2 Tbsp Tomato Paste
- 4 cups Cooked Chicken, shredded (approx. 1.5 lb)
- 1 medium Yellow Onion, finely diced
- 4 oz Cream Cheese (full-fat, softened)
- Salt and Black Pepper, to taste
- 12 Corn or Flour Tortillas (6-inch)
- 3 cups Shredded Monterey Jack or Cheddar blend (divided)
Instructions:
- Preheat the oven to 375°F (190°C). Grease the 9x13 inch baking dish. Shred the chicken and dice the onion.
- Start the Sauce (The Roux): Heat the oil in a large skillet over medium heat. Whisk in the flour and cook for 1 minute until a smooth paste forms (the roux).
- Bloom the Spices: Reduce heat to low. Whisk in the chili powder, cumin, oregano, garlic powder, and salt. Cook for 30 seconds until very fragrant—this 'blooms' the spices and deepens the flavor.
- Whisk in Liquid: Gradually whisk in the warm chicken broth until smooth, ensuring no lumps remain. Stir in the tomato paste. Bring to a simmer, then reduce heat and cook for 5–7 minutes, stirring occasionally, until the sauce has thickened enough to coat the back of a spoon. Taste and adjust seasoning.
- Sauté Onion: Sauté the diced onion in a separate pan until translucent, about 5 minutes.
- Combine Filling: In a large bowl, combine the shredded chicken, sautéed onion, softened cream cheese, and a ½ cup of the shredded cheese. Mix well until the cream cheese is evenly distributed and binds the chicken mixture slightly. Season with salt and pepper.
- Sauce Base: Pour about 1 cup of the enchilada sauce into the bottom of the prepared baking dish and spread evenly.
- First Tortilla Layer: Arrange four tortillas over the sauce, overlapping slightly to cover the bottom entirely.
- First Filling Layer: Spread half of the chicken filling evenly over the tortillas.
- Second Sauce & Cheese Layer: Ladle 1 cup of sauce over the filling, followed by 1 cup of the remaining shredded cheese.
- Repeat: Add a second layer of four tortillas, followed by the remaining chicken filling.
- The Finale: Top with the final layer of four tortillas. Pour the remaining sauce over the top, spreading it out to cover the tortillas fully.
- Final Cheese: Sprinkle the remaining 1½ cups of shredded cheese generously over the top.
- Bake: Bake uncovered for 25–30 minutes, or until the sauce is bubbling around the edges and the cheese is melted, golden, and browned slightly.
- Rest (Don't Skip This!): Remove from the oven and let the casserole rest on a wire rack for 10 minutes. This allows the liquid to redistribute and the structure to set up.
- Serve: Slice and serve while hot with your favorite toppings.
