EVERYTHING Gluten-Free at In-N-Out in 2023

“Quality You Can Taste” always rings a bell when you hear it. After all, everyone in America must know that line by now thanks to In-N-Out’s fine-tasting burgers. They just keep getting better every day!

But, is there anything gluten-free at In-N-Out?

Actually, In-N-Out is a great place to get something gluten-free without having to worry too much. Almost everything on the menu has no gluten… except for the buns.

When getting burgers, ask for no buns and have a Protein Style burger instead, which is just the burger wrapped in lettuce. It only gets better when you learn that even their fries are cooked in a separate fryer for gluten-free visitors!

All you need to do is let them know of your condition and you’re good to go!

Sounds too good to be true, doesn’t it? 

The nature of In-N-Out still poses a risk for cross-contamination, regardless of the strictest allergy protocols in place. Well, they still use flour-rich buns after all, which could come into contact with your gluten-free meal.

Thus, if you suffer from severe gluten intolerance or celiac disease, it’s best to avoid In-N-Out for your health and safety. 

But, not getting In-N-Out sucks! We know. So, to give you the best options for your Protein Style burgers, here’s a list of all gluten-free items on the menu.

In-N-Out Gluten-Free Options

In-N-Out Gluten-Free Options

In 1948, California witnessed its first drive-thru hamburger stand. This later became the In-N-Out that we love today.

Founder Harry Snyder would then personally visit meat and produce markets to handpick the freshest ingredients while his wife, Esther, took care of all accounting matters. 

Ever got curious why In-N-Out’s have crossed palm trees? This was actually inspired by one of Harry’s favorite movies, It’s a Mad, Mad, Mad, Mad World.

Just like how the characters raced to look for treasure under palm trees, Harry also planted crossed palm trees in front of In-N-Out, which was his own treasure. 

With now over 300 locations across the USA, the Snyders’ granddaughter continues her grandparents’ creative legacy, which has obviously become a massive success— as America still loves In-N-Out burgers almost 70 years later.

The impressively diverse menu suits all taste buds, making it a top destination among gluten-sensitive diners looking for a quick fix.

To show you what we’re talking about, we’ve already listed all available gluten-free options at In-N-Out to ease your next visit there.

(Note that these items are from In-N-Out’s online Allergen Info. The following are free of “Wheat/Wheat Gluten” as stated in the 2022 list.”)

Tips For A Gluten-Free Meal at In N Out

Give Them A Heads Up

Yes, In-N-Out is truly one of those great fast dining places to offer a decent number of gluten-free options.

However, since there aren’t gluten-free buns, it’s still best to alert your server before ordering and let them know of your condition to avoid the risk of cross-contamination. 

Always make sure to clearly state that you’re ordering the Protein Style burger. On top of that, tell them that you have celiac disease or gluten sensitivity, too.

This should alert them to take extra precautionary measures while prepping your meal.

No Onions and Sauce! 

In-N-Out offers customers the option of removing onions from their order. But, since grilled onions could be contaminated by flour particles from the same grill as buns, consider dodging the onions when getting a burger. 

Some visitors notice that the same knife can be used to spread sauce, take our advice for it and ask for your own sauce or mayo packet instead. 

Don’t Get The Cocoa

According to the allergen info online, hot cocoa is wheat-free… but it hasn’t been tested for wheat gluten. This distinction is important since an allergic reaction to wheat can differ from a reaction to gluten.

Some studies say that someone with a true allergy to wheat sometimes doesn’t react to the gluten but rather to other parts of the wheat plant. Basically, gluten is just one type of wheat allergen which you can react to. 

Thus, hot cocoa being entirely free of wheat gluten can’t be guaranteed. To be completely sure of your safety, try to dodge the hot cocoa and opt for other beverages instead. 

Cross-Contamination Risk

Fast foods are often a no-no when it comes to following a gluten-free regime due to the inevitable risk that floats around the place. This risk can lead to cross-contamination.

Cross-contamination occurs when gluten-containing items come into contact with gluten-free food.

It can happen in many ways. Either through direct contact with surfaces and utensils or when flour-rich particles transfer to gluten-free food when stored in a common area.

Most of those involved in food service don’t realize how dangerous this could be.

Unlike bacteria, gluten isn’t easily eliminated by heat. Gluten cross-contamination is only avoided when gluten is kept away from the workplace and by thoroughly cleaning anything that contacts the gluten-free item.

Despite the strictest measures performed by a restaurant to ensure a gluten-free meal preparation, unwanted things could still happen which could jeopardize your health. 

For In-N-Out, its nature as a fast-food chain specializing in burgers always poses a risk of cross-contamination. Imagine the flour from the buns touching the lettuce for your Protein Style burger. Obviously, your burger wouldn’t be much of a safe meal anymore.

Thus, it’s always best to keep an eye out for your meal when dining out anywhere.
