Can I use frozen green beans instead of fresh?

You can, but fresh really does make all the difference in texture. If you must use frozen, skip the blanching step and thaw them completely first - pat them dry so they don't water down your sauce.

What can I substitute for mushrooms?

Not a mushroom fan? Try diced celery or bell peppers instead. They'll give you that nice crunch without the earthy flavor. Just sauté them the same way.

Can I make this vegetarian?

Absolutely, Just swap the chicken broth for vegetable broth - it works beautifully. I've even used mushroom broth for extra umami flavor.

How do I keep the fried onions from getting soggy?

Two tricks: First, make sure your sauce is nice and thick before baking. Second, add half the onions at the start and the rest in the last 5 minutes of baking.

Can I freeze this casserole?

I don't recommend it - the creamy sauce tends to separate when thawed. It's so quick to make fresh, it's worth the little extra effort.
