Describe the Onion Wrapped Flying Dutchman Burger

In-N-Out burgers has the a double patty with double cheese called the flying dutchman. But what is making the viral rounds on social media is the version with thick slices of caramelized onions as the buns. From our research we learned how to order the flying dutchman the right way. Our preference of the flying dutchman is the “onion-wrapped” version and it’s delish. If you’re a fan of onions and a double cheeseburger, then this is the burger for you. It’s basically a very rich, very messy double cheeseburger with thick slices of grilled onions as the “buns”.

Overall Thoughts on This Crazy Decadent Burger

We actually really enjoyed the burger because we were craving cheeseburgers. So it was a fun way to satisfy a craving and make it low carb.

  • It’s really really rich. To minimize the all the fat and calories, just use one patty instead of a double patty.
  • We wrapped the burger in lettuce to break up the richness and it was great. It’s like chomping on a burger salad. Seriously, the lettuce really breaks up the richness and makes the double cheeseburger more digestable.
  • Don’t forget the homemade burger sauce. That’s what gives the flavor!
  • It’s messy, so have napkins ready. You could use a fork and knife, but that’s a little too precious for this onion wrapped flying dutchman burger. Just beast it and get your face all into it.

In-N-Out Copycat Onion Wrapped Flying Dutchman Burger

In N Out patties are classically very thin, but make the patties how you like – we prefer to make about 6 patties out of the 1 1/2 pounds of ground beef. And we find that beef with an 80-85% meat-fat ratio makes a great juicy burger without being overly greasy.
The burger sauce will make about a cup of burger sauce. You might not need it all, but it stores well in the fridge and is delicious on so many things.

Make the Homemade Burger Sauce

Cook the Onions and Burger Patties

  • Divide the ground beef into 4-8 equal balls, (depending on how thick you want the patties and if you are making singles or doubles – In N Out patties are usually very thin and you’ll want to make the patties that will be about as wide as the onion slices after the burgers cook and shrink a bit). Don't press or form the ground beef balls too tight. You want to have the ground beef loosely packed so the patties cook more tender and have a better texture when you smash them on the pan or griddle.
    forming burger patties
  • Slice the onions into intact rings about 1/2″ (12mm) thick.

  • Heat a large cast iron skillet or flat top griddle on medium-high heat. Drizzle about 1 Tablespoon (15ml) of oil on pan then lay onion slices on the hot pan. Season onions with salt and pepper.
    cooking raw onion slices
  • Cook the first side of the onions for about 2-4 minutes or until the onions are caramelized. Gently turn the onions, trying to keep the onion rings all intact. Season the remaining side with salt and pepper and cook other side until caramelized. Gently remove the cooked onion slices from the pan, still trying to keep the rings intact, and set aside.

  • In the same pan, lay the ground beef balls on the hot pan and press the meat with a spatula (or even a couple spatulas) to smash and form the patties. Season with salt and pepper to taste.

  • Cook the patties for about 2-3 minutes on each side or until it's nearly cooked to your liking (you'll still cook for a little more when you melt the cheese).

    flipping burger patties
  • Add cheese on top of each patty and let the cheese melt. Remove from heat.

  • Using the onion slices as the "bun", lay 1-2 patties on top of each onion slice. Add the burger sauce.
    finishing the burger
  • Top with remaining slice of onion. Eat right away and enjoy! It's messy so you might need a fork and spoon for this. (optional) Serve with pepperoncini or banana peppers. You can also add tomato or wrap it in lettuce so it tastes a little healthier!
