In-N-Out has built its reputation on consistency, but the chain occasionally makes quiet updates behind the scenes to keep improving what shows up on your tray.
The latest changes involve two ingredients customers interact with on nearly every visit, and both updates are already rolling out at restaurants now.
A Change to the Buns
In-N-Out has removed sesame flour as an ingredient in its buns across all sandwiches, including burgers and the chain's grilled cheese, at locations in all 10 states where it operates. The update follows the chain's pattern of periodically revisiting its ingredient list as part of what it describes as an ongoing commitment to quality and transparency with customers.
It's worth noting that In-N-Out still notes its buns are produced in a facility where milk, sesame, and soy are present, so those with allergies should continue reviewing the chain's allergen information directly rather than assuming the ingredient change eliminates all risk.
A Change to the Salt
Alongside the bun update, In-N-Out has also swapped its iodized salt for sea salt in the individual packets handed out with orders, most notably alongside the chain's well-known French fries. The packets themselves remain the same familiar single-serve format customers are used to.
Why These Changes Matter
In-N-Out has made similar ingredient updates before, including removing high-fructose corn syrup from its ketchup in 2025. The chain has framed these kinds of changes as part of a broader, ongoing effort to refine its ingredients over time, even when the changes themselves are subtle enough that most customers won't notice a difference in taste.
What to Expect Now
Both updated ingredients are already in place at In-N-Out restaurants. While the day-to-day experience of ordering shouldn't feel any different, the changes reflect the chain's continued attention to ingredient sourcing and quality behind the scenes.
The Takeaway
Whether or not you notice a difference in your next Double-Double, In-N-Out's latest ingredient updates are a reminder that even a famously simple menu is subject to ongoing refinement.
