Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can prepare the casserole a day in advance. Just assemble all the ingredients in the baking dish, cover it, and refrigerate. Bake it the next day, adding a few extra minutes to the cooking time if it's cold from the fridge.

What can I use instead of cream of mushroom soup?

If you prefer a homemade option, you can create a simple white sauce with butter, flour, and broth. Alternatively, cream of chicken or cream of celery soup works well as a substitute for a different flavor profile.

Can I add other ingredients to the casserole?

Absolutely! Feel free to mix in cooked bacon, sausage, or sautéed vegetables like bell peppers or spinach for added flavor and nutrition. Just ensure that the additional ingredients are cooked before adding them to the mixture.
