Vegan Options at White Castle (Updated 2022)

White Castle Vegan Options

White Castle has been serving up Impossible Sliders since way back in 2018.

Considering some of the hype Burger King got over their Impossible Whopper and Pizza Hut recently got for it’s Beyond Meat, we feel like White Castle’s Impossible Slider has flown a bit under the radar.

If you’ve gone vegan recently and used to love those steamed burgers with pickles and onions from White Castle, we highly suggest giving the Impossible version a try.

In addition to the sliders we detail every vegan option from White Castle below. Enjoy!

Our Picks

Ryan’s Pick: Let me preface my pick/review with the fact that I wasn’t a huge White Castle fan pre-vegan. I’ve had the Impossible Sliders a couple times and, for me, they’re okay. I think if you liked White Castle though, then they might be a great option.

What I do like are the old school crinkle cut fries, pretty good with some ketchup.

Jen’s Pick: N/A
