Double Green, Green Bean Casserole | Feed Your SkullI don’t know if you caught yesterday’s post for French Onion Kale Chips but they make this vegan green bean casserole!

I’ve wanted to recreate my favorite holiday casserole for some time and when I was planning out November I wrote it down.

It was time to replace some of the less than desirable ingredients. First being the favorite French’s onions and then the cream of mushroom soup that is full of so many other ingredients – let’s bring it back to mushrooms. Shall we?

First up the crunchy onion topping. I schemed for weeks on a topping to use that would perfectly substitute those naughty but delicious French’s onions (turns out they’re not as naughty as the soup).

French Onion Kale ChipsAnd it hit me. Kale chips. Crunchy onion kale chips. A chip that would taste great rehydrated within the casserole and also add that perfect texture on top.

Double the Green, Green Bean Casserole | Feed Your SkullTo replace the cream of mushroom soup, I first looked to my favorite soup recipe on FYS, a Foodgasmic Potato Crimini soup but decided it had too many ingredients and steps like the baked potato, but it still provided inspiration.

I wanted this side to be perfect, so I made 3 variations (each one built upon the first with little tweaks and adjustments) until it was just right.

Yes, we ate a lot of green bean casserole over a few days. 😉

In the first 2 variations I used 1/2 an avocado instead of cashews and though it does work – avocado does turn brown, so aesthetically the casserole looked much different after a few hours even though the flavor was still good. Cashews on the other hand worked perfectly! So perfect that there wasn’t any separation of ingredients after cooking like there was with the avocado (even with tapioca starch/wheat flour).

The latest greatest version of the green bean casserole was delicious right out of the oven, later in the evening, and even as breakfast the next day.

Without further ado…
