And one menu gem thats currently making the rounds on TikTok is the Flying Dutchman.

After watching countless videos of the burger being made, I needed to try it ASAP.

For those unfamiliar, a Flying Dutchman consists of a hamburger with grilled onions in place of the bun.

The grilled onions provide a savory and slightly sweet element, enhancing the overall taste of the dish.

For onion lovers like myself, this secret menu item is a dream come true.

Although white onions are what In-N-Out uses, I think red or yellow onions would be just as delicious.

Once it was stacked, I was ready to dig in.

After one bite, I was immediately in love.

From the seasoned lean beef to the creamy sauce, I understood why the secret item is so popular.

I found that half an inch was the perfect balance for flavor and structure.

Overall, I would definitely make this burger again.

Try it for yourself, and this burger might just claim the title of your new favorite.
