Method
- Heat your oven to 375 degrees. Lightly grease a 9x13 inch baking dish. In a medium bowl, combine the shredded chicken, drained green chiles, sour cream, cumin, garlic powder, onion powder, salt, and pepper. Stir well until the chicken is evenly coated and the sour cream is fully mixed in.
- Pour the tomatillo sauce into a small saucepan and warm it over medium-low heat until it is just hot enough to dip into, about 3 to 4 minutes. Pour about half of the warmed sauce into a shallow bowl or pie plate wide enough to lay a tortilla flat. Keep the remaining sauce in the pan on low heat.
- Dip each tortilla briefly into the warm sauce, about 5 seconds per side, until the tortilla is lightly coated and has softened slightly. Do not soak it through. Lay four tortillas in the bottom of the prepared baking dish, overlapping them slightly to cover the base completely, as you would with lasagna sheets.
- Spread half the chicken mixture evenly over the tortilla layer, then sprinkle 3/4 cup of the Monterey Jack cheese over the filling. Dip four more tortillas and lay them over the cheese, pressing down lightly with your palm so the layer is flat and compact. Repeat with the remaining chicken mixture and another 3/4 cup of Monterey Jack.
- Dip the final four tortillas and lay them on top to finish the last layer. Press down gently again. Pour the remaining tomatillo sauce evenly over the entire surface, spreading it all the way to the edges so every tortilla is covered.
- Scatter the remaining 1 cup of Monterey Jack and all of the cheddar cheese evenly over the top. Cover the dish tightly with aluminum foil and bake for 25 minutes, until the sauce is bubbling at the edges and the casserole is heated all the way through.
- Remove the foil and bake for another 12 to 15 minutes uncovered, until the cheese on top is fully melted and golden in spots. Let the casserole rest for 8 to 10 minutes before cutting. This resting time helps the layers firm up so your slices hold together. Serve topped with fresh cilantro, sliced green onions, and a squeeze of lime.
Notes
Assembling one day ahead and refrigerating overnight actually improves this casserole because the layers meld together. Add 10 minutes to the covered bake time if going straight from the refrigerator. Leftovers keep covered for 4 days and reheat well in the microwave or a covered oven dish.
