- Replace cream of mushroom soup with cream of chicken or cream of celery for a unique twist.
- For a different topping, try toasted almonds or crushed Ritz crackers for added crunch. I love topping mac and cheese with Ritz crackers as well!
Why use canned green beans instead of fresh?
I know it goes against what so many others prefer, but I actually like using canned green beans over fresh for this casserole. I find the texture to be softer and more consistent, without the stringiness that fresh green beans can sometimes have.
Plus, canned green beans are so convenient—they’re pre-cooked and ready to go, which saves time and simplifies the recipe. For me, they deliver the perfect balance of tenderness and flavor that works beautifully with the creamy sauce and crispy topping.
