Can I use chicken breasts instead of thighs?
Yes, but chicken thighs stay moister during baking. If using breasts, reduce baking time by 5-10 minutes and check for doneness at 160°F internal temperature.
Can this casserole be made ahead?
Yes, assemble completely, cover with foil, and refrigerate up to 24 hours before baking. Add 10-15 minutes to baking time if baking from cold.
What can I substitute for cream cheese?
Use sour cream or Greek yogurt mixed with a bit of butter for a lighter version, or Mexican crema if available. The texture will be slightly thinner.
Is this recipe spicy?
Mild to moderate heat from green enchilada sauce and diced green chiles. Adjust spice level by choosing mild or hot sauce, or omit chiles for less heat.
How do I know when the casserole is done baking?
Chicken reaches 165°F internal temperature at thickest point, and the cheese topping is melted and lightly browned, about 35-40 minutes at 350°F.
