Notes

Make sure you cut or snap the ends off of the green beans for the best texture and overall experience. I always make sure to trim the tough stem ends of the green beans because they can be fibrous and hard to chew, not exactly enjoyable!
This green bean casserole is gluten-free and dairy-free, and it’s all about keeping the beans tender and soft, but never mushy.
If you know you’ll be short on time, grab some fried onions and sauce at the store. You can also buy pre-sliced mushrooms.

If you’re not using a high speed blender, I recommend soaking the cashews overnight or boiling them for 20-25 minutes to soften them. This will give the casserole the best consistency!

While this is a green bean casserole without milk or cheese, it is still made with fresh ingredients and needs to be stored properly and refrigerated. I recommend only keeping it out for a few hours on the serving table.

I know this casserole is ready when the onions on top are lightly golden brown. I always make sure not to leave it in the oven too long, no one wants a mushy casserole!
