Making it a definite “must have” dish for your holiday table. No canned soup or green beans in this baby! I did use canned crispy onions to save time but you can make your own as well.

I used frozen french green beans because the are already blanched and more readily available in any area. If you are using fresh green beans, be sure to blanch them and then shock in cold water first.

Here are step by step instructions on How to blanch green beans

Why french green beans? They tend to stay tender/crisp, hold their shape and keep their bright green color. And they are more flavorful than their larger counterparts.

Once you try this French Green Bean and Mushroom Casserole, you will never go back to those mushy canned green beans or condensed mushroom soup again.

Add you will get better health benefits from using nutrient rich fresh ingredients and a lot less salt! Real simple ingredients but big on flavor!

Enjoy!
