Shake Shack French Onion Menu Singapore: Our Honest Ratings

Our scores, item by item

French Onion Shack Stack, 9/10. A beef patty with Gruyere and caramelised onions, plus a whole fried 'Shroom Burger stacked in. Honestly the one you should get. We paid $18.20 for it.

Onion Rings, 8/10. Not too oily, and very good dunked in the sauce. French Onion Soup Burger, 7/10, it was missing a bit of crunch. French Onion 'Shroom Burger, 7/10, basically a deep-fried mushroom full of cheese, so hard to hate. Parmesan Garlic Fries, 6/10. Decent, but at the end of the day they are just fries.

What was on the French Onion menu

Shake Shack Singapore announced the menu on its own blog on 14 January 2026. The French Onion Soup Burger came as a single, double or triple, with Gruyere, caramelised onions, crispy onions and roasted garlic parmesan aioli. Then the 'Shroom version, the Shack Stack, the Parmesan Garlic Fries and the brand's first-ever onion rings.

The menu started in the US and went viral on TikTok before it landed here. Shake Shack's launches are usually consistent, and this was no exception.

What it cost us, and is it still around

Our total bill was $49.68 for three burgers, two sides and two drinks, when we went in January 2026. Steep for fast food, but fair for a launch you only get once.

The French Onion burgers were a limited run. When we checked Shake Shack Singapore's menu page in October 2026 they were gone, but the onion rings had stayed on the regular menu, now with a sour cream onion dip.
