Notes
FAQ
Can I use fresh or frozen green beans instead of canned?
Absolutely! For fresh green beans, trim and cut them, then boil until tender-crisp (about 5-7 minutes) before using. For frozen green beans, thaw them completely and pat dry to remove excess moisture.
What is the purpose of the soy sauce?
The soy sauce is a “secret” ingredient that doesn’t make the casserole taste like soy, but rather deepens the overall savory flavor (umami) and enhances the color of the sauce.
Can I make this casserole ahead of time?
Yes, you can assemble the casserole (without the final onion topping) up to a day in advance. Cover and refrigerate. When ready to bake, you may need to add 5-10 minutes to the baking time since it will be cold. Add the topping for the last 5 minutes as directed.
My casserole is too runny. How can I thicken it?
If using fresh or frozen green beans, ensure they are well-drained and patted dry. You can also reduce the milk by 1/4 cup. If it’s still runny after baking, let it stand for 10-15 minutes before serving; it will thicken as it cools slightly.
