Frequently Asked Questions

Can I use fresh broccoli instead of frozen?

If you prefer not to use canned soup, you can make a homemade version using cream, broth, and sautéed mushrooms to create a similar flavor and texture.

Can this casserole be made ahead of time?

Absolutely! You can prepare the casserole in advance and store it in the fridge, then bake it just before serving. This makes it ideal for busy nights or gatherings.
