Wondering what’s vegan at White Castle? In this fast food guide, we’ll share all the dos and don’ts of ordering plant-based burgers and salty sides. With 377 locations nationwide, will they finally fulfill our desire for vegan cheese? Keep reading to find out!

When it comes to burgers (plant-based or otherwise), you wouldn’t think that we’d be overly partial to a particular patty shape. But, we seem to be deeply drawn to and ultimately attracted by the small, solitary squares of a certain burger building. If you’re one of millions attracted to these sassy sliders, you’ll be happy to know how to order vegan at White Castle.

On the other hand, if your first instinct is to positively pass by this burger place, you may want to reconsider. Though far from healthy and having only a few plant-based products, it’s got much better options than either McDonald’s, Burger King, or Subway for vegan versions of beef-based sandwiches.

Vegan Options at White Castle

While you certainly don’t have to be a knight or lady-in-waiting to wander into White Castle, all customers are not afforded the luxury of a myriad of menu items. Are you ready to find out which White Castle vegan options are open to passionate plant-based eaters like us? Here’s what you can expect!

Does White Castle Have Vegan Cheese?

Starting in March 2020, White Castle began offering dairy-free cheddar cheese by GoodPlanet Foods, but only at their NY and NJ locations in the US. Make sure to ask before ordering. If White Castle has expanded their menu to include more locations, it could be the one that you’re at right now!

What To Order At White Castle

Ordering vegan at White Castle is simple because you only have a two burger options and a couple of potato choices. Let’s cross our fingers that they start offering vegan cheese at ALL locations and not just in two states. If you’re unsure how to plan your plant-based, fast food meal, here are a few suggestions:

  • Basic Breakfast Ideas – Order two crispy slices of wheat toast with jelly (or jam) and include an order (or two!) of golden hash brown nibblers. Dunk into sweet Mrs. Butterworth’s syrup and add an apple or orange juice on the side. You may want to grab a steaming cup of hot coffee or tea, too.
  • Burgers All the Way – Your best bet is to choose either (or both!) the Impossible Slider (with no cheese) or the Veggie Slider (with no ranch) and add on an order of crispy fries. If you’re extra hungry, double your burger and fries and also include some appetizing onion rings (if you’re lucky enough to be in the correct state). Since vegan cheese is only currently offered in NY and NJ, consider bringing some vegan slices of your own if you’re not in these states!
  • Sustain Yourself With Snacks – When you’re on the go and just slightly snack-y, strive to keep it simple. Buy a side order of fries with a selection of dipping sauces, a Crave Cooler (or other sweet liquid treat), or even better, a serving or two of applesauce. No need to overthink it.

Helpful Hints When Ordering Vegan at White Castle

  • Browse the White Castle menu before ordering.
  • If ordering White Castle through a delivery service, make sure you clearly specify any substitutions you would like. Especially concerning cheese and meats. If you’re worried that your request may not be honored (or seen by the server at White Castle), it might be a better idea to go there directly to order. 
  • Download the Nutrition Information PDF and Ingredient List PDF to make sure that you are purchasing a vegan-friendly item. The menu items offered at White Castle do change and the PDFs seem to be updated regularly.
  • From past experience, it seems that most (if not all) seasonal drinks or foods are not vegan because of added dairy milk or milk derivatives. Be careful when new and exciting seasonal products are offered at White Castle. Double check the allergens and ingredients page to make sure that the item is vegan before purchasing.

Creating a Kinder and More Accessible White Castle.

It’s only a matter of time before more vegan options land on the menu. That’s the direction all the big fast food chains are heading, and White Castle knows that they can add a few more items that are vegan-friendly, such as vegan cheese. But meanwhile, we can always write to, call, or contact the managers of any location to make our requests. 

How to Order Vegan at White Castle Burgers and Beyond

What Do We Know About White Castle?

Did you know that White Castle was the first American fast food chain? In 1921, Walt Anderson began flipping quick and inexpensive burgers back in Wichita, Kansas. The iconic white castle exterior that we all recognize today is actually only 28 feet square and, though it started off as location No. 8, now acts as a souvenir stand.

Ever wonder how White Castle got its unique name? After the 1906 novel, The Jungle, highlighted the harsh, cruel, and unsanitary conditions of the meat packing industry, not many people were as motivated to support the business of burgers. The owner decided to upgrade the reputation of the restaurant by using the castle motif as representing ‘strength’ and the color white for ‘purity’. Apparently, it worked well for them.

Fun Facts About White Castle

  • Most sliders eaten in one sitting is 103 (at least so far!)
  • They sell a hamburger scented candle (what???)
  • The exclusive square shape was the result of trying to fry meatballs on a flat surface. In frustration, Anderson used his spatula to squash the patty, thus creating the classic boxy burger we all associate with White Castle.
