Low-FODMAP at Five Guys
Everything is made to order, so a plain, onion-free burger is easy to get. The fresh-cut fries are naturally low-FODMAP — the only catch is the enormous portion. The spread and steak sauces are where the garlic and onion hide.

What to order
These are the dependable low-FODMAP picks — and why each one is a safe bet.
Bunless burger or lettuce wrap
Fresh 100% beef patty — the bun is the only wheat.
Fries (order the 'little' size)
Fresh-cut potato in peanut oil — low-FODMAP; just mind the portion.
Lettuce, tomato, pickle, green pepper, jalapeño, mustard, ketchup, mayo
All low-FODMAP toppings you can pile on freely.
Cheese and bacon
Both fine — hard cheese is low-lactose.
What to ask the kitchen to change
These can work — with one question or one small adjustment. Here’s exactly what to ask.
The bun
Ask for it in a lettuce wrap or bunless — the buns are wheat.
The toppings
Skip raw and grilled onions, and mushrooms, plus BBQ and steak sauce (garlic and onion). Load lettuce, tomato, pickle and peppers instead.
What to skip
Not forever — most of these come back during reintroduction. During elimination, they’re the reliable triggers to leave off.
Buns
Wheat.
Grilled or raw onions and sautéed mushrooms
Onion and polyols.
BBQ sauce and A1 / steak sauce
Onion and garlic.
The full-size fries in one go
Potato is low-FODMAP, but that portion stacks it.
The exact words to say
Specific beats vague every time. Most staff won’t know what “low FODMAP” means, but they can absolutely answer “is there onion or garlic in that?”
“Bunless bacon cheeseburger, lettuce wrap, no onion or mushroom — mustard and pickle.”
“A little fries, please.”
