Notes

Ingredients

  • 2 Tbsp canola oil
  • 3 garlic cloves, finely chopped
  • 1 jalapeño pepper, seeded and finely chopped
  • 1 large onion, diced
  • 3 cups shredded cooked chicken
  • Two 4-oz cans diced green chiles
  • ½ tsp paprika
  • Kosher salt and black pepper, to taste
  • Two 10-oz cans green enchilada sauce, divided
  • ⅔ cup sour cream
  • 18 corn tortillas, cut in half
  • 3 cups Monterey Jack cheese, freshly grated (about 12 oz)
  • Fresh cilantro, chopped, for serving

Instructions

  1. Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish and set aside.
  2. Heat the canola oil in a large skillet over medium heat. Add the garlic, jalapeño, and onion and sauté for about 3 minutes, stirring occasionally, until the onion is soft and translucent and the garlic is fragrant.
  3. Add the shredded chicken, diced green chiles, paprika, salt, and pepper to the skillet. Reserve ½ cup of the enchilada sauce in a small bowl. Pour the remaining enchilada sauce into the skillet and stir to combine. Cook for 1–2 minutes until everything is warmed through. Turn off the heat and stir in the sour cream until the filling is smooth and creamy.
  4. Spread the reserved ½ cup enchilada sauce in an even layer across the bottom of the prepared baking dish.
  5. Arrange 12 corn tortilla halves across the bottom of the dish in a single overlapping layer to cover the surface. Spread one-third of the chicken filling evenly over the tortillas and sprinkle with 1 cup of Monterey Jack cheese.
  6. Repeat this process twice more — tortilla layer, chicken filling, 1 cup cheese — for 3 complete layers total.
  7. Bake uncovered for 30–35 minutes, until the cheese on top is golden and the sauce is bubbling at the edges. Rest 10 minutes before slicing. Scatter fresh cilantro over the top and serve.
Notes
  • Aromatics matter: Don't rush the sauté — 3 minutes in the skillet builds the flavor foundation for the whole dish.
  • Sour cream tip: Always stir it in off the heat to keep the filling silky and smooth.
  • Make-ahead: Assemble up to 24 hours ahead, refrigerate covered, and add 10–12 extra minutes to bake time from cold.
  • Storage: Refrigerate for up to 3–4 days. Reheat covered at 350°F for 20 minutes.
  • Spice control: Keep the jalapeño seeds out for mild; leave some in for heat. Totally customizable.
