Gluten Free White Castle Secret Menu (Including Breakfast, Sauces, Fries)

Gluten Free Diet | Written by Nathan Petitpas | Updated on 15 April 2023

A burger made with beef patty, lettuce and ketchup wrapped in a white takeout packaging and placed on top of a table napkin, makes dieters wonder if there is a gluten free burger that can be ordered from the gluten free White Castle menu.

When someone has gluten-associated medical problems, it can be difficult to find gluten free White Castle options or other ways to enjoy popular chains.1, 6 As you may be aware, gluten is the main protein in wheat, and as much as the 7% of the population of US may have intolerances or conditions that cause gluten to become harmful.2

On the surface, a gluten intolerance may make most burgers off limits, but luckily there’s still some menu items White Castle that are GF as seen on the secret menu that includes breakfast, sauces, and fries are also considered although they’re not quite GF at this restaurant. 

Is White Castle Gluten Free?

Under normal conditions, only the drinks, milkshakes, smoothies, condiments, and applesauce at White Castle are gluten free. All of the bread in White Castle foods have high gluten content, and breaded, fried foods will also have high amounts of gluten.

For that matter, any deep fried foods at White Castle have minor traces of gluten due to cross contamination from the shared vats.

That said, there are options at White Castle to eat gluten free foods, or to eat certain foods without the gluten-heavy components. 

The Complete Gluten Free White Castle Menu

Many foods at White Castle are never gluten free. However, everything on the following menu is either gluten free or can be gluten free with minor accommodation from the kitchen staff.

Modifications like ordering a bunless burger aren’t on the official menu, but customer reviews indicate that staff are often helpful when it comes to secret menu-style preparation.

Gluten Free Burgers and Toppings

Low-Gluten White Castle Options

Besides the truly gluten free foods at White Castle, there’s also a range of foods that have extremely small traces of gluten. These are either below or just above the tolerable threshold for gluten content among those with celiac disease.

While it’s potentially harmful for a celiac to eat even small quantities of these foods, those with more common, milder gluten intolerances may consider enjoying them in moderation.

  • French Fries, Medium (600 calories)

  • Hash Rounder Nibblers, Medium (720 calories)

When is White Castle Gluten Free?

In short, White Castle is gluten free when the food either has no gluten content or doesn’t come in contact with glutinous foods. For instance, the breaded chicken and fish at White Castle aren’t gluten free because of the breading.

Most of the sliders would be gluten free, except the bun has gluten in it. But if the meat and toppings never touch bread and the staff wrap them in lettuce or tomato, that’s a gluten free burger.

White Castle doesn’t have an official policy on making burgers and sliders gluten free. This doesn’t mean that it’s impossible to request that the staff make a lettuce-wrapped burger, but it is up to their discretion.

If a person simply walks in and asks for a gluten free burger, there’s no guarantee that the staff will even understand what’s the customer is asking of them. Despite that, online reviews and individual experience indicating that the staff of White Castle are often accommodating and willing to take the steps to prepare a gluten free burger. 

Asking about practices at local locations is a good way to know about if there’s any unofficial policy in place, or if staff will accommodate the request. The Google My Business listing or Facebook page of a specific location are both suitable starting points, as is sending an email or calling in ahead.

It’s also acceptable to simply ask on the spot, although the staff might decline the request. If they’re not willing to do, so, that will mean there aren’t any gluten free meals available at the location.

Unfortunately, White Castle’s french fries always have traces of gluten and are never safe for someone with celiac disease or a strong gluten intolerance. 

Are There Gluten Free White Castle Fries?

Fries are the most popular side at White Castle, particularly the loaded fries that come with cheese and thick crumbs of bacon. Cheese, potatoes, bacon – none of these ingredients have gluten, so it seems like it’d be the perfect choice for someone with a gluten intolerance.

This isn’t the case, though, because of the preparation methods that White Castle uses for its fries. 

Since the chain doesn’t take precautions to prevent gluten contamination in its fried foods, French fries from White Castle suffer gluten contamination. Incidentally, this also means that all other deep fried foods at White Castle aren’t gluten free.

The White Castle Hash Rounds would be gluten free, except that they also fry in the same vat as glutinous foods. 

Why Aren’t White Castle Fries Gluten Free?

Gluten remains intact throughout the frying process, so breaded foods leave gluten particles behind in the oil that they were fried in. These particles transfer over to any food that fries in the same oil. According to studies on gluten cross-contamination in fryers, the rates of contamination are inconsistent and it’s impossible to safely predict whether these contaminated fries will have sufficiently low gluten levels for a celiac.3

Depending on the amount of breaded food that the staff have used the fryer to prepare, gluten concentration can vary widely. It’s usually somewhere between 20 and 80 parts per million (PPM), which may not sound like much but which can quickly add up.

Having celiac disease means that a person can only tolerate about 10 mg of gluten per day, but a 5.5 ounce serving of fries in oil with 80 PPM gluten will end up having more than 12mg of gluten.4 A small order of fries at White Castle is 5.2 oz, which translates into a roughly 20% chance of being unsafe for celiac. 

However, celiacs have an extremely low tolerable threshold for gluten, much lower than non-celiac gluten sensitivity.5 In comparison, milder gluten intolerance shouldn’t prevent someone from enjoying a small or medium order of White Castle fries. 

The only way that a restaurant can make gluten free fries is by having a special fryer set aside. By separating gluten-free foods and frying them in oil that hasn’t touched foods with gluten, restaurants can prevent gluten cross-contamination.

However, there are no White Castle restaurants that do this as of November 2022. Without these measures, there’s nothing that individual manager and staff can do to prepare gluten free fries. 

A person could try to ask for the staff to change the oil in the vats before preparing their fries. This would not produce gluten free White Castle fries, though, because there would still be residual gluten. The chance of gluten content surpassing the threshold that people with celiac disease can handle is still there.

GF Example Order at White Castle: Gluten Double Smoked Cheeseburger with Ice Tea and a Strawberry Shake

Start with a double smoked bacon cheeseburger and request that the staff wrap it in lettuce or at least serve it without the bun. Request an iced tea as the drink, and place an order for a strawberry shake as dessert. With proper food handling, the meal will be entirely gluten free and have the following macros:

  • Calories: 740
  • Net Carbs: 106g
  • Protein: 26g
  • Fat: 27g 

In any case, it can be difficult to eat out with celiac or other gluten sensitive conditions so be sure to follow this secret menu and its special instructions around burgers and fries to enjoy low-gluten and gluten free White Castle snack or meal.
