Can I make sour cream chicken enchilada casserole ahead of time?

Yes, this casserole is very make-ahead friendly. You can assemble it completely, cover it tightly, and refrigerate it for up to two days before baking. Let it sit at room temperature for about 30 minutes before putting it in the oven so it heats evenly.

Why did my sour cream sauce separate or look grainy?

This usually happens if the sauce gets too hot after adding the sour cream. Sour cream should always be stirred in off the heat, then gently warmed through during baking. Even if it looks slightly separated before baking, it usually smooths out once the casserole cooks.

Should I use flour tortillas or corn tortillas?

Both work, and it really comes down to texture preference. Flour tortillas bake up softer and more casserole-like, while corn tortillas give a more traditional enchilada flavor with a slightly firmer bite. Just make sure corn tortillas overlap well so they don’t dry out.

How do I keep my enchilada casserole from turning soggy?

Using a sauce that’s thick enough before layering is key. Also, avoid overloading the casserole with extra fillings that release water, like fresh tomatoes. Letting the casserole rest for about 10 minutes after baking helps everything set up nicely.
