Is there gluten in In-N-Out milkshakes? Your Complete Guide

4 min read

According to official company allergen information, In-N-Out's milkshakes are made with gluten-free ingredients. However, navigating a fast-food menu with dietary restrictions requires understanding more than just ingredients, especially for those with celiac disease or severe gluten sensitivity.

Quick Summary

In-N-Out's standard milkshakes are made without gluten-containing ingredients, but customers should always inform staff of a gluten allergy to activate safety protocols and minimize cross-contamination risks during preparation.

Key Points

  • Ingredient Safety: In-N-Out's vanilla, chocolate, and strawberry milkshakes are made with gluten-free ingredients.

  • Cross-Contamination Protocol: To minimize risk, inform the staff of a "gluten allergy" when ordering to ensure gloves are changed and clean utensils are used.

  • No Gluten Add-ins: Unlike some other chains, In-N-Out does not offer malted milk or cookie additions that contain gluten, simplifying the ordering process.

In-N-Out's Gluten-Free Shake Ingredients

In-N-Out Burger has long been a popular choice for those with gluten restrictions, largely due to its simple menu and clear allergen policies. The good news is that the core ingredients used to create their delicious shakes do not contain gluten. This includes all three standard flavors: vanilla, chocolate, and strawberry. The shakes are made with real ice cream and simple flavorings, which is a key reason for their gluten-free status. For those who enjoy a mix, the famous Neapolitan shake (a combination of all three) is also considered safe. The company's allergen menu publicly lists the shakes as milk-based products, with no indication of wheat or other gluten sources.

Why Do In-N-Out Shakes Stand Out for Gluten-Free Dieters?

Unlike some competitors, In-N-Out does not offer flavored mix-ins like malt powder or crushed cookies (e.g., Oreo) that typically contain gluten. This simplifies the ordering process and significantly reduces the risk of accidental exposure from shared ingredients. The entire shake preparation process is isolated from the main food line, further minimizing cross-contamination possibilities, especially when staff are made aware of an allergy.

The Critical Factor of Cross-Contamination

While the ingredients are free of gluten, a safe dining experience depends entirely on managing cross-contamination risks during preparation. In-N-Out is known for having specific protocols to address these concerns, but customers must be proactive.

What to Do When Ordering

When placing your order, it is crucial to explicitly state that you have a "gluten allergy". Simply asking for a shake might not trigger the necessary precautions. This keyword prompts the crew to change gloves and use fresh, clean utensils to handle your order. This is a standard procedure that many fast-food restaurants don't offer, making In-N-Out a standout option for the gluten-sensitive community. While shakes are generally prepared away from the bun area, this step provides an extra layer of protection.

Other Potential Contamination Sources

It's important to be aware of other items on the menu that contain gluten. The hamburger buns are the primary source of gluten in the restaurant. Hot chocolate is also flagged by the company as possibly containing gluten. When ordering a shake, ensure that the cup and lid are not placed near buns or other contaminated surfaces at the pickup counter.

Best Practices for a Safe In-N-Out Experience

Here's a step-by-step guide to ensure your In-N-Out milkshake is as safe as possible for a gluten-free diet:

  1. Place Your Order Clearly: When ordering, say, "I have a gluten allergy. Can I please have a vanilla shake?"
  2. Verify the Protocol: Ask the cashier to confirm that the staff will change gloves and use clean equipment.
  3. Use Digital Ordering (If Applicable): For some, this can reduce miscommunication. Use the notes section to specify the allergy.
  4. Order During Off-Peak Hours: Crowded times can increase the chance of human error. Visiting during less busy periods allows staff more time to follow protocols carefully.
  5. Watch the Preparation (When Possible): At the pickup counter, be vigilant to ensure your shake cup isn't placed directly on a surface used for buns.
  6. Trust Your Gut: If something seems wrong or a staff member appears confused by your request, do not take a risk. Your health is more important.

Can you get a Neapolitan shake safely?

Yes, absolutely. The Neapolitan shake is made by combining the three standard shake flavors, all of which are gluten-free. By following the same allergy protocol as for a single-flavor shake, you can enjoy this special item without worry.

Conclusion

For those with celiac disease or gluten intolerance, the answer to "Is there gluten in In-N-Out milkshakes?" is no, based on their ingredients. The company's basic shake recipe is gluten-free, and they have established protocols to address cross-contamination concerns. However, the safety of your dining experience is dependent on clear communication with the staff. By specifying your gluten allergy and confirming the use of clean equipment, you can enjoy a delicious shake from In-N-Out with confidence.

Important Considerations

While In-N-Out is a relatively safe fast-food option for gluten-free individuals, it's not a certified gluten-free facility. There is always a small, inherent risk of cross-contamination in any shared kitchen. For this reason, those with the most severe sensitivities must always proceed with caution and follow all recommended protocols to minimize risk.
