YouTube Video – Vegan Green Bean Casserole Recipe

Welcome to the latest installment of the NACFORADVENTURE YouTube channel. This week, I make one of my favorite recipes, green bean casserole. This recipe is an updated version of the Very Mushroom Thanksgiving Green Bean Casserole recipe from last year.

As someone who has a plant-based diet, I am constantly learning new ways to improve copycat recipes, and I couldn’t be more happy with how this week’s recipe came out. With a creamy mushroom base and some (absolutely delish!!!) crunchy fried onions, this recipe seriously hit it out of the park, and I’m excited I get to share it!

So make sure you have the four main ingredients; mushrooms, green beans, oat milk and an onion, and let’s get to it!

The recipe is posted below, but feel free to be intuitive. It usually works out for me…
