Shake Shack’s best-performing limited-time menu is back. The Black Truffle Menu returned nationwide on Tuesday, September 29, 2026, and it runs through Sunday, November 15 — and this year it is bigger than before, with the black truffle sauce available as an add-on for the first time and a brand-new side on the board. Here is everything on it, what it costs, and how long you have left to get it.
The short version: five items, all built around a black truffle sauce made with truffle oil hand-crafted in Umbria, Italy — a quarter-pound Angus burger, a crisp-fried portobello ‘Shroom, the burger-and-‘Shroom Shack Stack, Parmesan fries with the sauce on the side, and new Mac & Cheese Bites. Order at the counter, in the app, or for delivery at participating US Shacks.
What Is on the Black Truffle Menu?
The star is the sauce: black truffle sauce made with black truffle oil hand-crafted in Umbria, Italy, the same sauce that has anchored every return of this menu. Shake Shack calls the Black Truffle Menu one of its best-performing limited-time menus ever, and this year’s version spreads the sauce further than any before it. For the first time, you can add the sauce to sides — the new Mac & Cheese Bites, Chicken Bites and Onion Rings — instead of only getting it on the built items.
The line-up: the Black Truffle Burger, a quarter-pound 100% Angus beef patty with fontina cheese, crispy sweet onions and black truffle sauce on a toasted potato bun; the Black Truffle ‘Shroom, a crisp-fried portobello mushroom filled with melted muenster and cheddar, topped with shredded lettuce and the sauce; the Black Truffle Shack Stack, which stacks the Angus patty and the cheese-filled ‘Shroom together with fontina and sauce; Black Truffle Parmesan Fries, crinkle-cut fries dusted with Parmesan and served with the sauce on the side; and the new Mac & Cheese Bites, crisp bites filled with ditalini pasta in a creamy cheddar and American cheese sauce.

Shake Shack does not publish one national price, so the ranges above are compiled from live listings checked October 26, 2026: delivery menus at six US stores (Gaithersburg, Scottsdale, Chicago, New York, Berkeley, Poughkeepsie) plus in-store menu listings in Kansas City, Austin and Las Vegas. Delivery prices run a dollar or two above the counter — at launch, Fast Food Post put the in-store span at $6.29–$16.79, and the Mac & Cheese Bites carry a suggested price of $5.99. Your Shack’s price may sit outside the range; the app shows your store’s number before you order. Calories are Shake Shack’s published nutrition figures. The fries are the calorie heavyweight at 800 — the sauce on the side does the damage — while the ‘Shroom is the lightest sandwich on the board at 450.
When Can You Get It?
The menu returned Tuesday, September 29, 2026 at participating Shake Shack locations nationwide, and it runs through Sunday, November 15, 2026. That is about seven weeks — longer than most fall LTOs — but “for a limited time” still means it disappears when the window closes, and popular items have sold through early in past returns. If you want the Shack Stack, do not leave it to the last weekend.
One date has already passed: Shake Shack celebrated the return with a Black Truffle Window pop-up in New York City, at 204 Mulberry Street near Little Italy, on Friday, October 23 and Saturday, October 24. Anyone could walk up with any food — a slice of pizza, a bagel, leftover pasta — and get it topped with the black truffle sauce for free, while supplies lasted. The window was a nod to Florence’s historic wine windows and to the Italian roots of the truffle oil in the sauce. It is over now; the menu itself is the way to get the sauce.
How to Order It
Order at the counter, in the Shake Shack app, or on shakeshack.com for pickup or delivery — the full Black Truffle Menu is on all three at participating locations. The new move this year is the sauce add-on: in the app, you can add black truffle sauce to Mac & Cheese Bites, Chicken Bites or Onion Rings, which turns a regular side into a truffle one. No separate add-on price is published in the menus we checked, so the upcharge shows in the app at your store. There is no loyalty-program gate and no member early-access window this time — it is on the menu for everyone from day one.
A practical note on value: the Shack Stack is the priciest item on the board and the heaviest at 720 calories, while the ‘Shroom at 450 calories is the cheapest way into the truffle sauce. And if you are comparing burger boards this fall, our Burger King menu has the Whopper math, the McDonald’s menu covers the Big Mac, and the Wendy’s menu has the Baconator — none of them is doing truffle this season.
