In-N-Out’s Bun and Salt Changes Are Sparking a Fan Debate
A few small ingredient updates are giving In-N-Out customers something new to talk about. The chain has made changes to its hamburger buns and salt packets across its 10-state footprint, creating discussion among fans who are noticing adjustments at a restaurant known for consistency.
The updates are not a major menu overhaul. In-N-Out has changed the ingredient makeup of its hamburger buns by removing sesame flour, and it has replaced iodized salt packets with sea salt packets.
For customers, those changes may be subtle, but they are the kind of details that can stand out at a restaurant where many fans expect the same experience every time they order.
What Changed at In-N-Out Restaurants
The biggest adjustment is the burger bun. In-N-Out has removed sesame flour from its hamburger buns, changing the ingredients used in one of the chain’s most recognizable menu components.
The company has also updated the salt packets available for customers. Instead of iodized salt packets, restaurants now use sea salt packets for requests involving salt for fries or other items.
In-N-Out says the changes are part of its effort to serve the “freshest, highest-quality food possible.” The company has not announced a wider recipe overhaul or changes to the core menu.
The updates apply throughout In-N-Out’s 10-state footprint, which includes California, Nevada, Arizona, Utah, Texas, Oregon, Colorado, Idaho, Washington, and Tennessee.

What Customers May Notice
For some diners, the bun change may be the most noticeable update. Removing sesame flour means the hamburger bun now has a different ingredient profile, and some customers may notice differences in texture or appearance.
The salt update is another visible change, especially for customers who ask for salt packets with their order. Those packets now contain sea salt rather than iodized salt.
The chain also previously made another ingredient change in 2025 when it updated its ketchup by replacing high-fructose corn syrup with real sugar. That update is separate from the latest bun and salt changes but is part of the company’s recent ingredient adjustments.
While some online commenters have said they noticed differences or welcomed the changes, those reactions represent individual opinions rather than a broad measurement of customer opinion.
Why Fans Are Discussing the Changes
In-N-Out has built a reputation around a consistent menu, so even small ingredient adjustments can attract attention from longtime customers.
Some online commenters supported the removal of sesame flour, while others questioned the move to sea salt or said they preferred the previous bun. These comments show different customer reactions, but they do not represent a formal survey of In-N-Out fans.
One follow-up report highlighted a single social-media commenter who described the bun as “crumbly.” That reaction should be viewed as one person’s experience, not as evidence of a widespread product issue.
For a chain with a loyal customer base, small changes can become part of a larger conversation about whether a familiar favorite still feels the same.
What Has Not Changed
Despite the ingredient updates, In-N-Out has not announced a new burger, a new fry recipe, or a major redesign of its menu.
The company also has not announced a switch from sunflower oil to beef tallow for its fries.
The bun update should not automatically be interpreted as meaning restaurants are sesame-free or that the change has specific allergy implications. Customers looking for ingredient or allergen details should check information directly from In-N-Out’s official materials.
What Local Customers Should Know
Customers who want to know whether their nearby restaurant is using the updated buns and salt packets can contact their local In-N-Out restaurant or reach out to the company for confirmation.
Because the changes apply across the chain’s 10-state footprint, the updates are expected to reach restaurants throughout those areas rather than being limited to one market.
Still, individual customer experiences may vary. Some diners may notice the updated ingredients immediately, while others may not notice a difference at all.
The latest changes show how even small adjustments can create a conversation when a restaurant brand has built its identity around familiarity. For In-N-Out fans, the menu may look the same, but some of the details behind the meal have changed.
