If you are on social media at all, chances are you have seen the viral videos of In-N-Outs flying Dutchman burgers all over TikTok and Instagram. It is all the rave and worth all the hype especially if you are on a low-carb diet. Skip the buns and replace them with fried onion patties. The onion patties are first sauteed on a pan or grill pan and then set aside until the beef patties are cooked. Once the beef patties are cooked, you then assemble the burger with double patties, cheese slices, and use the fried onion patties in place of buns. The burgers are then served with a homemade In-N-Out sauce that I made healthier using Greek yogurt instead of mayonnaise.

ingredients you will need

  • Ground beef burger patties: I always use the leanest ground beef I can get my hands on. You may also use other types of meat like ground chicken. The whole idea is to use ground beef though.
  • Kosher salt and pepper, to taste
  • Olive oil: or you may also use avocado oil
  • Cheese slices of choice, divided- I love cheddar, American, or Provolone
  • Yellow onion, cut into 4 x 1/2 inch thick rounds: find large sizes for this to work.
  • Greek yogurt: I use this in place of Mayonnaise. You can use lite mayonnaise or sour cream.
  • Relish or chopped pickles
  • Sugar or honey or agave
  • White wine vinegar: or lemon
  • Ketchup: can’t skip this.
  • Yellow mustard: or honey mustard

Meanwhile, preheat a large heavy-bottom skillet over medium heat. Drizzle with 1 tbsp of oil and cook the onion rounds until golden brown on both sides. Add 2 of the cheese slices on 2 onion rounds and set aside on a plate. Cover to keep warm and help the cheese melt.

To the same preheated skillet, add the patties and cook until it start to get golden brown, then flip them and add the remaining cheese slices of 2 of your cooked patties. Continue to cook for 1 more minute, or just until the cheese starts to melt.

    1. Hi John, that was in step 6? How can I make it better? Also, the sauce can be served in between the patties or you can spoon it on the burger or dip the burger in sauce.
