Ready in under 30 minutes, this vegan green been casserole features green beans, mushrooms, and of course crispy-fried onions. It’s all brought together with a simple to prepare cream sauce flavoured with lemon, onion, and garlic.


Preparing Vegan Green Bean Casserole
This is not a difficult recipe, but it does have a few steps.
Start by juicing a lemon, setting the juice aside and then slicing the remaining lemon peel into quarters. Put the lemon peel and green beans in a skillet with barely enough water to cover and steam the green beans for a few minutes, until your desire doneness. Then drain the green beans and put them in the freezer while you make the sauce. Freezing them will stop them from cooking further. Another way to do this is to have them sit in an ice bath, but I find this works just as well, with less fuss.
Next, you make the sauce. You just need to put all the dry ingredients, plus water, in a blender, so this comes together really quickly. It’s especially speedy if you already have some of my 4 minute cheeze sauce mix on hand, but even if you don’t it’s just 4 dry ingredients that take no prep time. Today, we’re flavouring the sauce with green bean casserole-appropriate onion and garlic powder.
You may be surprised at the addition of something cheesy to the sauce, but it isn’t adding a big cheezy note here, but instead is a super fast method for whipping up a quick and creamy sauce.
Next we’ll cook the mushrooms, and then add our cheeze sauce mixture to them.
To finish the dish off, you’ll add some lemon juice, then add in the green beans and simmer until hot. And last, by definitely not least, add in the crispy fried onions.

Notes
Storage and Reheating
I think this is best served soon after you make it. But if you have leftovers, you can reheat it in the microwave, or over low heat in a saucepan.There Isn’t Supposed to Be Cheese In this Recipe! So What’s the Deal with using 4 Minute Cheese/Cheeze Sauce Mix?
4 minute cheeze sauce is very mildly flavoured and it’s an easy way to make a creamy base for lots of different recipes. Since I was making 4 minute cheeze sauce so often, I decided to make a pantry-staple version of it. This is just a pre-combined version of all of the cheese sauce ingredients, except the water.
