The In-n-Out's Flying Dutchman is a simple yet mouth-watering creation, featuring just two ingredients: beef patties and cheese. Yes, you read that right. The In-n-Out's Flying Dutchman is essentially a cheese sandwich, but instead of bread, it uses two beef patties. It's a low-carb dream come true, and it's surprisingly easy to prepare.
Begin by preparing your beef patties. It's important to use fresh beef to capture the same quality that In-N-Out prides itself on. Shape the beef into thin patties that are roughly the same diameter as a typical burger bun. The thinness helps the patties cook quickly and evenly, which is crucial for the Flying Dutchman.
Next, heat a pan or griddle over medium-high heat. Once the pan is hot, add the patties and a thick full slice of the onion. Cut the Slice about a 1/4". You want to tray and soften the onion but keep it together at the same time. You can use toothpicks or just flip carefully.
In-N-Out is known for its well-seared patties, so make sure your pan is hot enough to sear the beef quickly, locking in the juices. Cook the patties for about 2-3 minutes, then flip and cook for another 2-3 minutes.
When the patties are nearly done, lay a slice of American cheese on each patty. The heat from the patties will start to melt the cheese. To help it along, you can cover the pan with a lid for the last 30 seconds or so of cooking.
Once the cheese is melted, use a spatula to stack one patty on top of the other, cheese sides together, and stick the onion in between the two as if the burgers are sandwiching the oinion. The result is a cheese-filled burger with no bun in sight.
