A correction to what this page said before
An earlier version of this page told you that Morton’s publishes no allergen information online, that its allergen menu exists only inside the restaurant, and that the only thing you could do was ask your server. That was wrong.
Morton’s publishes a full per-item allergen menu on its own website. We did not find it the first time because it is not linked from the homepage, the menu index, the FAQ or any location page, and it is not in Morton’s sitemap. It was found by guessing the URL. Morton’s own FAQ — which is what the previous version of this page relied on — still says to ask a server for it, which reads as though the document is offline. It is not.
We are saying this plainly rather than quietly rewriting the page, because the correction reverses the advice. The previous version left about a dozen dishes marked “we cannot say.” Morton’s own document says most of them contain dairy.
Answer: Morton’s flags every single one of its sides as containing dairy
Morton’s publishes allergen data for its menu, and by that data there is no confirmed vegan dish on it. All thirteen published sides — including every one this page used to recommend — carry a dairy flag. So do the salads. Morton’s marks no item vegan or vegetarian anywhere.
Everything below was read from Morton’s own allergen documents on 31 July 2026.
Where the data actually is
The index page is mortons.com/allergens/, titled “Allergen Information.” It links three documents, each a full menu with per-item allergen flags and calories:
The flags Morton’s uses are dairy, egg, fish, sesame, shellfish, soy, tree nut and wheat. Morton’s does not publish a peanut flag, and it publishes no vegan or vegetarian designation at all.
Morton’s attaches this note to each document, verbatim:
“NOTE: We strive to provide accurate allergen information for the major food allergens identified as ingredients in our standard menu items. However, because our kitchens and food suppliers prepare a variety of dishes, where cross-contact may occur despite using all reasonable precautions, we cannot guarantee that any item is completely allergen-free. Additionally, guests are responsible for informing their server of any food allergies, dietary restrictions, or sensitivities so we can support your dietary needs and provide the best possible dining experience. If you have any questions regarding the allergen notice, please ask to speak with a manager.”
The sides — all thirteen, all flagged dairy
This is Morton’s complete published Sides section, with the restaurant’s own item names, its own calorie figures and its own allergen flags. There are no other sides.
- Brussels Sprouts — 550 cal — dairy
- Charred Broccolini — 460 cal — dairy, sesame, soy
- Creamed Spinach — 510 cal — dairy, wheat
- King Crab Whipped Potatoes — 1,190 cal — dairy, shellfish, soy
- Loaded Baked Potato — 1,430 cal — dairy
- Lobster Macaroni Shells & Cheese — 1,360 cal — dairy, shellfish, soy, wheat
- Parmesan & Truffle Matchstick Fries — 890 cal — dairy, wheat
- Roasted Jumbo Asparagus — 160 cal — dairy, egg
- Sautéed Spinach & Button Mushrooms — 180 cal — dairy
- Smoked Gouda & Bacon Au Gratin Potatoes — 860 cal — dairy, fish, soy, wheat
- Sour Cream Mashed Potatoes — 840 cal — dairy
- Thick Cut Onion Rings — 1,070 cal — dairy, wheat
- Truffled Cream Corn — 660 cal — dairy, egg
Two of those are worth pausing on, because they are the ones a vegan diner would most likely assume are safe. Roasted Jumbo Asparagus is 160 calories — the lightest thing in the section — and Morton’s flags it dairy and egg. Sautéed Spinach & Button Mushrooms is 180 calories and flagged dairy. Neither name suggests either.
What this reverses on this page
These are the items the previous version of this page recommended or left open, and what Morton’s own allergen menu says about each. In every case the verdict moves from “unverifiable” to “not vegan.”
- Sautéed Brussels Sprouts — previously “exists, unverifiable.” Morton’s flags it dairy. Not vegan.
- Thick Cut Onion Rings — previously “exists, unverifiable.” Morton’s flags it dairy, wheat. Not vegan.
- Jumbo Grilled Asparagus — previously “exists, unverifiable.” Published as Roasted Jumbo Asparagus and flagged dairy, egg. Not vegan.
- Sautéed Spinach & Button Mushrooms — previously “exists, unverifiable.” Flagged dairy. Not vegan.
- Loaded Baked Potato — previously flagged here as something that should not have been on a vegan list, by inference. Now confirmed from the brand: dairy.
- Chopped House Salad — previously “exists, unverifiable.” 410 cal, flagged dairy, egg. Not vegan.
- Baked French Onion Soup — previously corrected to French Onion Soup Gratinée by inference from the word “gratinée.” Now confirmed: 530 cal, flagged dairy, soy, wheat.
- Morton’s Iceberg Wedge — previously noted only as renamed. Published as Steakhouse Wedge Salad, 790 cal, flagged dairy, egg. Not vegan.
One more from the bar menu, because it is the sort of thing that catches people out: Hand-Cut Potato Chips, 1,710 calories, are flagged dairy, egg and fish. A bowl of potato chips is not a plant-only order here.
Morton’s contradicts itself on the onion rings
The same item carries different flags on two of Morton’s own documents. On the dinner menu, Thick Cut Onion Rings are flagged dairy, wheat. On the bar and Power Hour menus, the same 1,070-calorie item is flagged dairy, egg, wheat.
We are not picking a side. Morton’s publishes both, and if you are avoiding egg the safe reading is the one that includes it. Either way the item is flagged dairy on all three documents, so it is not vegan on any of them.
What the allergen menu still does not tell you
This matters, because an allergen document is not a vegan document.
Morton’s flags eight allergens. None of those flags covers beef stock, chicken stock, gelatin, honey, carmine or rennet. An item could carry no flag at all and still be an animal product — and Morton’s publishes no ingredient lists, so there is no way to check. The absence of a flag is not a vegan mark, and this page will not treat it as one.
What the data does support is the reverse, and that is what makes it useful: where Morton’s flags dairy or egg, the item is ruled out. On the sides, that is all thirteen.
Morton’s also publishes no frying-oil statement and no preparation statement beyond the cross-contact note quoted above.
The FAQ still says something different
Morton’s FAQ page says, verbatim and still live:
“Morton’s The Steakhouse is pleased to offer a selection of menu items tailored to various dietary needs and allergen sensitivities. Please ask your server for our allergen sensitive menu when dining with us.”
That is the sentence that sent the previous version of this page to the wrong conclusion, and it is worth knowing it is still there. The allergen menu is published online, at the addresses above. You do not have to be in the restaurant to read it, whatever the FAQ implies.
Other corrections carried over
These were made in an earlier pass and still stand.
Five items no longer exist on any Morton’s location menu checked: Wild Mushrooms, Seasonal Burrata Salad, The Troy, Herb Roasted Cauliflower, and the raspberry or mixed-berry dessert. Of the drinks the page once named, nine of eleven “Mixology” cocktails, all four dessert coffees, both “Free Spirits,” the French Martini and three of four champagnes return no hits. The headings “Morton’s Mixology 18,” “Seasonal Cocktails 18” and “Free Spirits 10” were prices misread as section names.
Two safety claims were removed because Morton’s publishes nothing to support them: that “the staff will also ensure to clean up everything, including utensils and other kitchen tools to avoid cross-contamination,” and that Morton’s “follows its strict protocol when it comes to avoiding cross-contamination.” What Morton’s actually publishes about cross-contact is the note quoted earlier, and it says the opposite: it cannot guarantee any item is allergen-free.
The claim that “the sauces at Morton’s The Steakhouse are non-vegan” was removed as unsourced. The allergen menu now partly answers it: all ten published Enhancements are flagged dairy, and Béarnaise Sauce is flagged dairy, egg, fish, soy.
Also removed previously: “peanut-free, nut-free dishes,” the claim of “about 80 locations” when Morton’s own locator lists 62, the Playboy Club founding narrative, and the ESPN and celebrity-event claims. And roughly half of the old page was not about Morton’s at all — a 24-figure vegan-steak nutrition table, a section on WHO carcinogen classifications, an Oxford bacon study, a USDA sodium figure, an Impossible-versus-Beyond comparison and a list of home vegan-steak ingredients. All gone.
What to do if you are eating there
Read the allergen menu before you go — it is the document Morton’s tells you to ask a server for, and it is linked above. Then understand what it can and cannot settle for you: it will rule things out reliably, and on the sides it rules out everything. It will not confirm anything as vegan, because Morton’s publishes no vegan designation and no ingredient lists, and stock and gelatin sit outside every column it does publish.
Menus also vary by location, and Morton’s says so. The allergen documents are the national ones.
