Plate · Green Chile Chicken Enchilada Casserole

First written down, Autumn 2008

The common failure mode of any enchilada casserole is a soggy, indistinct mass where the tortillas dissolve into the sauce. This happens when corn tortillas are layered raw. Frying the tortillas briefly in oil before assembly creates a barrier that repels excess moisture, allowing them to soften in the oven while retaining their distinct layers.

Using a tomatillo-based green chile sauce provides a sharp, acidic counterpoint to the richness of the cheese and sour cream. Shredded cooked chicken thigh meat is preferable to breast meat here, as it withstands the double-cooking process without drying out. The cheese blend relies on Monterey Jack for melting and sharp cheddar for flavor.

This casserole requires a brief resting period after baking to allow the layers to set, making it easier to slice cleanly. It can be assembled up to a day in advance and refrigerated before baking, though you will need to add ten minutes to the covered baking time. Serve with a simple cabbage slaw dressed in lime juice to cut the richness.

Measurements

Metric converts only measures that are mathematically safe. Density-dependent cups stay as Nicole wrote them.

Scaling this one

This recipe is written to fill one 9x13 pan, so there is no batch slider: doubling the quantities would not give you a deeper pan, it would give you two of them — and the bake time and temperature below would no longer be right. To make more, run the recipe twice in separate tins rather than crowding one.

Sauce and Filling

  • 28 ounces canned green enchilada sauce
  • 1/2 cup sour cream
  • 3 cups cooked chicken thighs, shredded
  • 1/4 cup fresh cilantro, chopped
  • 1/2 teaspoon kosher salt

Assembly

  • 1/4 cup neutral oil, such as canola
  • 18 six-inch yellow corn tortillas
  • 8 ounces Monterey Jack cheese, freshly grated
  • 8 ounces sharp cheddar cheese, freshly grated

How it goes

Method

Read the whole thing once before you start. Nothing here is difficult, but the timing is unforgiving at the end.

  1. Prepare the sauce mixture

    In a large bowl, whisk together the green enchilada sauce and sour cream until smooth. This addition tempers the acidity of the sauce and adds a creamy texture that binds the layers. Set aside one cup of this mixture for the final topping.

  2. Mix the chicken filling

    Add the shredded chicken, chopped cilantro, and kosher salt to the remaining sauce mixture in the bowl. Toss until the chicken is evenly coated. Coating the meat ensures it remains moist during the baking process.

  3. Fry the tortillas

    Heat the neutral oil in a skillet over medium-high heat. Using tongs, fry each tortilla for about 10 seconds per side, just until pliable and slightly blistered. Drain on paper towels. This brief frying creates a lipid barrier that prevents the tortillas from turning to mush in the casserole.

  4. Layer the casserole

    Spread a thin layer of the reserved sauce in the bottom of a 9x13-inch baking dish. Arrange six fried tortillas in an overlapping layer. Top with half of the chicken mixture and one-third of the combined grated cheeses. Repeat with another layer of six tortillas, the remaining chicken, and another third of the cheese.

  5. Finish the assembly

    Top with the final six tortillas. Pour the remaining reserved cup of sauce evenly over the top, ensuring all tortilla edges are moistened to prevent curling and burning. Scatter the remaining cheese evenly across the surface.

  6. Bake and rest

    Cover the dish tightly with aluminum foil and bake at 375°F for 30 minutes. Remove the foil and bake for an additional 15 minutes, until the cheese is bubbling and lightly browned at the edges. Let the casserole rest for 15 minutes before slicing to allow the structure to set.

2 of these change the result. The rest are conveniences, with a workaround given. Nothing here is a brand recommendation — the spec is what matters.

  1. 9x13-inch baking dish

    The recipe's layer count and bake time are calculated for a 9x13 pan; using a significantly smaller or larger dish will change how the casserole heats and sets.

    What matters
    True 9x13-inch (23x33 cm) ovenproof dish, ceramic or metal with straight sides to hold multiple layers.
  2. 10-12-inch heavy skillet

    Frying tortillas in a thin, small pan cools the oil and produces soggy, greasy shells rather than the brief blistering this recipe needs.

    What matters
    10-12 inch skillet, cast iron or heavy-gauge stainless, flat-bottomed and able to hold medium-high heat without warping.
  3. Long-handled tongs

    Optional

    Tongs let you flip and lift hot tortillas cleanly so they blister evenly and you avoid burns or tearing the shells.

    What matters
    Long-handled (10-12 inch) heat-resistant metal tongs with a secure grip and scalloped ends for turning tortillas.
    If you skip it
    Use a long metal spatula or two forks to turn the tortillas carefully.

Cook's notes

What we would tell a friend

  • Do not skip frying the tortillas. If you are pressed for time, you can brush them lightly with oil and bake them at 400°F for 3 minutes, but the texture will be slightly inferior.
  • Store leftovers in an airtight container in the refrigerator for up to four days. Reheat individual portions in the microwave or the entire pan in a 350°F oven until warmed through.
  • To make ahead, assemble the casserole completely, cover tightly, and refrigerate for up to 24 hours. Bake covered for 40 minutes, then uncovered for 15 minutes.
