The original recipe is said to have been invented by an employee at Campbell's soup company in the 1950s. It's a popular side dish often served at holiday dinners like Thanksgiving or Easter.

How to make vegan green bean casserole
Vegan green bean casserole is just like the classic, but healthier and completely dairy-free. It's the perfect dish for Thanksgiving or any holiday dinner! We bake it in a casserole dish, but you can also use a large cast-iron skillet if you prefer.
Here's how we make it in a few simple steps:
- Start by preparing the easy-to-make magic mushroom sauce. Simply saute some mushrooms then blend with cashews. Easy!
- When it's ready, build your casserole by covering the bottom of your baking dish with mushroom sauce, followed by half the green beans. Repeat another layer of sauce, then green beans, and top with a bit of water to steam the beans. To seal in the moisture, cover it tightly with some aluminum foil.
- Bake it until it's hot and bubbly and the green beans look soft.
- Now, time to make the crispy topping. Cook the onion in a bit of oil until soft then add the panko until it turns golden.
- When the green beans are ready, mix them around a bit in the dish, pour the topping over it, and serve it right away!
