BY : PUBLISHED : November 9th, 2020 UPDATED: October 19th, 2021

This green bean casserole is another amazing recipe from The Friendly Vegan Cookbook and we are very excited for you to add it to your favorite casserole repertoire. It’s one of those comforting dishes that can take you back to childhood holiday memories as soon as you get a taste.

I wrote The Friendly Vegan Cookbook with Michelle Cehn, founder of World of Vegan, and we worked hard to recreate the most classic and loved recipes using only plant-based ingredients, for you to share with your friends and family. Grab a copy, cook away, and let us know which are your favorite recipes.

Creamy Casserole

his Green Bean Casserole is the miracle you’ve been hoping for, sure to please everyone at the table. It’s super simple, easy to make, and absolutely delicious. Without the need for cream, this casserole is as creamy as gets. A perfect and delicious side dish to entertain your family over the holidays.

But make no mistake, this comforting casserole doesn’t have holiday exclusivity. It would be a perfect recipe to make any time (especially during the colder months) and we encourage you to! Plus, if you are eating a few portions of veggies while at it, then it has a year-round free pass, right?

If you’re one of those anti-green beans souls, please let us know if you tried this recipe! We are so keen to hear about your experience.

The Secret is in the Crispy Onions

The creamy sauce and cheesy flavor are reasons enough to fall in love with this Green Bean Casserole but what elevates it the most are the salty and crispy onions on top. These little crunchers are absolutely delicious and can become the topping of many different dishes if you’re feeling creative. You can find them at Trader Joe’s, Sprouts, and other grocery stores. Beware, they are addictive.
