The Truth About In-N-Out Ketchup Ingredients
For most individuals with a gluten intolerance or sensitivity, the question, "Is the ketchup at In-N-Out gluten-free?" has a straightforward answer: Yes, the ingredients are free of gluten. In-N-Out serves Heinz ketchup, a brand that confirms its ketchup products are gluten-free. This applies to both the ketchup dispensed from the red squeeze bottles and the single-serving packets. The basic components, including tomato concentrate, vinegar, sugar, salt, and spices, do not contain gluten. However, the ingredient list is only half the story, as cross-contamination presents a significant and real danger for those with Celiac disease.
The Critical Issue of Cross-Contamination
The most significant risk to a gluten-free diner at In-N-Out comes from the potential for cross-contamination, not the inherent nature of the condiments. In-N-Out has a very simple kitchen layout, and while they follow certain protocols for allergy safety, gluten-containing buns are prepared right next to other ingredients.
The Ketchup Squeeze Bottles vs. Ketchup Packets
While the ketchup in the squeeze bottles is technically gluten-free, there is a risk involved. The restaurant environment is busy, and it's possible for someone to touch a gluten-filled bun and then grab the ketchup bottle, transferring gluten residue. The safest option by far is to use the individual, sealed Heinz ketchup packets. These are kept under the counter and you can simply ask an employee for some packets to ensure your ketchup has not been handled in the busy condiment area.
Cross-Contamination with In-N-Out's Spread
A major source of cross-contamination involves In-N-Out's signature "spread," which is made with a combination of mayonnaise, ketchup, and relish. While the spread's ingredients are gluten-free, staff often use the same utensil to spread it on buns and also dip back into the sauce vat. This practice makes the spread unsafe for Celiac diners. It is crucial to specifically order your burger without the spread and request individual packets of ketchup instead.
Gluten-Free Ordering and Safety Precautions at In-N-Out
To ensure your meal is as safe as possible, there are several steps you can take. Your communication with the staff is your most powerful tool.
Ordering Protein-Style Burgers
When ordering a burger, always request it "protein-style," which replaces the standard bun with a lettuce wrap. This eliminates the main source of gluten. You should also specify that you have a "gluten allergy" when you order. This triggers a specific protocol where employees are trained to change their gloves, clean the work station, and use dedicated utensils for your meal to minimize the risk of cross-contact.
Handling Additional Toppings
Some toppings, like the diced grilled onions, can also pose a cross-contamination risk because they are often turned with the same spatulas used for the buns. If you want grilled onions, request whole grilled onions or ask the staff to use a clean grill area and spatula.
Safe Condiments and Toppings
Here are some of the other naturally gluten-free condiments and toppings available at In-N-Out, as long as you account for cross-contamination risks:
- Mustard: Provided in squeeze bottles, same risk as ketchup squeeze bottles. Request packets for safety.
- Relish: A component of the spread; ask for it separately if you can get assurance of no shared utensils.
- Tomatoes, Onions, Lettuce: Naturally gluten-free, but ask staff to change gloves before handling.
- Pickles: A safe and tasty topping option.

Other Gluten-Free Items on the Menu
In-N-Out is a surprisingly safe fast-food option for gluten-free diets, with several items being naturally free of gluten ingredients.
French Fries
The french fries at In-N-Out are made from fresh-cut potatoes and cooked in a dedicated fryer with 100% sunflower oil. This makes them one of the safest options on the menu, as nothing else is fried in the same equipment. For animal-style fries, specify a "gluten allergy" to ensure they use separate tools for the toppings.
Milkshakes
All three milkshake flavors (vanilla, chocolate, and strawberry) are gluten-free and made with real ice cream. Like with other items, make sure to mention your gluten allergy when ordering to ensure clean equipment and gloves are used.
Conclusion: Safe Ketchup is a Packet Away
For those needing a strict gluten-free diet, the most important takeaway is that while In-N-Out's ketchup itself is gluten-free, the restaurant environment presents a cross-contamination risk. This is particularly true for the spread, which is made with ketchup and is applied with shared utensils. By ordering your burger "protein-style" with a "gluten allergy" note and specifically asking for sealed ketchup packets from under the counter, you can safely enjoy a meal at In-N-Out.

Note: While these practices significantly reduce the risk, no fast-food establishment can guarantee a 100% gluten-free environment. Those with extreme sensitivities should always exercise caution.
