The global gluten-free food market is expected to grow from $23.82 billion in 2025 to $43.87 billion by 2034, according to projections from Renub Research.
Operational Shifts in Fast-Food Allergy Management
Five Guys has emerged as a case study for this transition, largely due to its restrictive approach to shared equipment. According to the company, its fries are cooked exclusively in peanut oil within dedicated fryers that never touch other menu items, effectively isolating them from gluten-containing products.
At Five Guys, staff are instructed to follow specific allergy procedures when a customer discloses a medical need. Reporting from users on the subreddit r/glutenfree indicates that these measures often include changing gloves, wiping down grill surfaces, and sanitizing cold prep stations to prevent cross-contamination.
Pro Tip: Always inform the cashier of your allergy immediately upon ordering. Requesting an “allergy call-back” ensures the kitchen staff is alerted to initiate standard cross-contamination protocols, such as changing gloves and using fresh prep areas.
Comparison of Gluten-Free Menu Strategies
Not all chains approach the gluten-free market with the same strategy. While Five Guys has gained traction by focusing on “bunless” options like lettuce wraps and bowls, other competitors have opted for product substitution.
| Chain | Primary Strategy |
|---|---|
| Five Guys | Bunless/Lettuce wrap focus; dedicated fryers. |
| Culver’s, Chick-fil-A, Shake Shack | Availability of dedicated gluten-free burger buns. |
The absence of a gluten-free bun at some locations remains a significant point of divergence. For diners seeking a traditional burger experience, chains that source gluten-free bread provide a different value proposition than those that rely on the bowl-only model.
