Healthy Vegan Green Bean Casserole

Recipe Description

This Healthy Vegan Green Bean Casserole is another one of my delicious Christmas side dish recipes that the whole family will love this year. You will be surprised at how creamy this delicious mushroom sauce is – you will hardly believe that it is vegan.  

Start by making my creamy mushroom sauce. Assemble the casserole from the green beans and mushroom sauce. Bake until hot, bubbling and the green beans are soft. While the casserole is in the oven, prepare the topping by heating olive oil and cooking onion until soft and brown. Add the panko bread crumbs to the pan and leave to brown. Once the beans are soft, mix them around and pour the topping over the casserole. Serve immediately.

To make my Healthy Vegan Green Bean Casserole, you will need the following ingredients:

I made this green bean casserole for Christmas dinner, and it was a hit. Super creamy and no one even noticed it was vegan. I used fresh green beans from the farmer's market, and they really made it pop. A lil' time-consuming, but def worth it. Gonna keep this in my holiday rotation for sure.

I made this Healthy Vegan Green Bean Casserole for our Christmas dinner, and it was a hit! My husband, who usually isn’t a fan of vegan dishes, couldn’t believe how creamy the mushroom sauce was. It reminded me of the ones my mom used to make, but healthier. So thankful for this recipe.
