Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can prepare the casserole in advance. Assemble it, cover tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking straight from the refrigerator to ensure it heats through thoroughly.

Can I use fresh green beans instead of frozen?

Absolutely! If using fresh green beans, trim and blanch them in boiling water for about 3-4 minutes until slightly tender. Drain and cool before mixing them into the casserole. This will enhance the flavor and texture of your dish.

What can I substitute for French fried onions?

If you don't have French fried onions, you can use crushed potato chips or homemade crispy shallots as a substitute. Just ensure they are added at the end of baking to maintain their crunchiness.
