Low FODMAP at LongHorn Steakhouse
LongHorn is one of the easier chains to navigate because the core of the menu is fire-grilled meat plus simple potato and vegetable sides. The catch: every steak gets a signature grill seasoning by default, and that blend contains garlic and onion powder, while the fan-favorite appetizers and add-ons (Texas Tonion, Wild West Shrimp, garlic butter finishes) stack onion, garlic, wheat, and dairy. Order your steak seasoned with salt and pepper only, keep sides plain, and skip the complimentary honey wheat bread.
✅ Safest picks
Flo's Filet (6 oz)
Plain grilled beef contains no FODMAPs at all — the only issue is the default grill seasoning, which includes garlic and onion powder.
💬 Order it: Ask for it seasoned with salt and pepper only, no signature seasoning and no butter or sauce finish; pair with a plain baked potato.
Renegade Sirloin (6 oz)
A lean, unbreaded cut with no wheat or dairy in the meat itself; the standard seasoning blend is the only common-trigger source.
💬 Order it: Request salt-and-pepper-only prep and confirm no marinade or garlic butter is brushed on before serving.
LongHorn Salmon
Grilled fish is naturally free of common triggers, but the house marinade and seasoning can carry garlic and added sugars.
💬 Order it: Order it plain-grilled with no marinade or bourbon glaze — just salt and pepper — and skip any sauce on top.
Grilled Lobster Tail (add-on)
Lobster with plain drawn butter is low in common trigger ingredients, since butter is mostly fat with minimal lactose.
💬 Order it: Ask for plain drawn butter only — no seasoning blend or garlic butter brushed on the tail.
Plain Baked Potato (side)
A plain potato has no onion, garlic, wheat, or notable lactose, making it the safest side on the menu.
💬 Order it: Order it plain or with a pat of butter; skip the loaded version's sour cream and cheese if dairy bothers you.
Fresh Steamed Broccoli (side)
Broccoli florets are lower in trigger carbohydrates in a modest serving, and this side comes without onion or garlic sauces.
💬 Order it: Ask for it steamed plain with no seasoning butter, and stick to about half the serving rather than a heaping portion.
⚠️ Skip these
Good to know
- •Ask for any steak seasoned with salt and pepper only — LongHorn's signature grill seasonings contain both garlic powder and onion powder by default.
- •Skip the complimentary honey wheat bread basket: it combines wheat flour and honey, two triggers in one warm loaf.
- •Build the classic safe plate: plain-seasoned steak, plain baked potato, and plain steamed broccoli — avoid the seasoned rice pilaf and mashed potatoes, which bring onion seasoning and dairy.
- •Decline garlic butter and sauce finishes on steaks, shrimp, and salmon; ask for plain butter or olive oil instead.
- •The seasoned French fries carry a seasoning blend and share a fryer with breaded items — a plain baked potato is the more predictable choice.
- •On salads, order no croutons and no red onion, and choose oil and vinegar or a plain vinaigrette over creamy garlic-based dressings like Caesar or ranch.
