Forget everything you thought you knew about fast food burgers. Shake Shack is about to blow your mind with their latest culinary creation that’s part comfort food, part gourmet experience.

Starting September 12th, the popular burger chain is launching a French onion soup-inspired menu that’s guaranteed to make your taste buds do a happy dance. The headliner? A French Onion Soup Burger that’s not just a meal, but a flavor explosion. Priced at $10.99, this burger features a quarter-pound 100% Angus beef patty topped with Gruyère cheese, caramelized onions, crispy sweet onions, and a roasted garlic Parmesan aioli – all nestled on a toasted potato bun.

But wait, there’s more. For those seeking vegetarian options, the French Onion 'Shroom Burger offers a fried portobello mushroom stuffed with melted Muenster and cheddar cheeses. And for the truly indulgent, the French Onion Shack Stack combines a beef patty and a 'Shroom Burger in one epic sandwich.

Shake Shack’s CEO Rob Lynch describes this menu as the “democratization of fine dining,” promising restaurant-quality burgers at fast food prices. The chain is clearly pushing boundaries, offering gourmet-inspired items that challenge traditional fast food expectations.

Side lovers aren’t forgotten either. The much-requested onion rings are finally making their debut, crafted from sweet Spanish onions and beer-battered to crispy perfection. Parmesan Garlic Fries round out the menu for those craving something extra.

As an added bonus, Shake Shack is also bringing back their Coffee Shake just in time for National Coffee Day, blending dark roast coffee with house-made vanilla frozen custard.

This isn’t just a menu update – it’s a culinary revolution that proves fast food can be innovative, delicious, and surprisingly sophisticated. So mark your calendars and get ready to elevate your fast food experience.
