Vegan Green Bean Casserole
This is literally the BEST Vegan Green Bean Casserole I have ever had. It is comforting, creamy and crunchy all at the same time. Perfect holiday side!
I took a poll on Instagram stories to see what recipe you guys NEEDED this Thanksgiving and the overwhelming answer was a Vegan Green Bean Casserole! Well you asked for it, so here it is. And I am so excited to share this one.
Not only is it freaking delicious, it is super easy to make! And can you really go wrong with green beans swimming in a creamy onion sauce and then topped with crispy onions?!? The answer is no, trust me.
To make or buy the crunchy onions
When it comes to a green bean casserole, you have 2 options for that crunchy topping. Make it from scratch, or buy it pre-made. I went the pre-made route. It is faster, easier and it is so easy to find crispy onions at just about any grocery store.
I got mine at Trader Joe’s, but you can buy them online or at your regular grocery store as well!
Why didn’t I use mushrooms?
Well, to be honest, I don’t love mushrooms. I like them in some recipes, but I really wanted this one to highlight the onions. And you still get a great flavor without using mushrooms, trust me.
If you absolutely have to have them, go ahead and add a cup of chopped mushrooms while the onions and garlic are cooking down. This will add more water to the sauce, so just keep that in mind and adjust your flour ratio if needed.
Can I make this ahead of time?
This is best prepared and served right away. Mostly because the green beans will continue to cook as they sit in the casserole dish. BUT, if you need to make this ahead of time, I would prep the green beans (through the ice bath step) and place them, drained, in a container. Then prep the sauce, let it cool, and place it in a separate container. Refrigerate overnight.
When you are ready to serve, combine the sauce and the green beans in a casserole dish. Stir to combine and top with the rest of the crispy onions. Pop it in the oven, covered, at a lower temperature (around 375) for 20-30 minutes. Remove the cover and broil the top for 2-3 minutes.
This is if you want to prep everything a full day before serving. If it is just going to be a couple hours, then make the casserole, cover it, and reheat in the oven right before serving.
