Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can assemble the casserole a day in advance and store it in the refrigerator. Just cover it tightly with foil. When you're ready to bake, you may need to add a few extra minutes to the cooking time if baking straight from the fridge.

What can I use instead of sour cream?

If you want to replace sour cream, Greek yogurt is an excellent substitute that provides a similar creaminess and tang. You could also use cream cheese for a richer flavor, just make sure to soften it before mixing it into the casserole.

Is this casserole freezer-friendly?

Absolutely! You can freeze the unbaked casserole for up to 2 months. Just cover it tightly with foil or plastic wrap. When ready to enjoy, thaw it in the refrigerator overnight before baking. Adjust baking time as needed for a perfect finish.
