This is the viral In-N-Out Onion-Wrapped Burger. Also known as the Flying Dutchman from In-N-Out. It’s a great low carb or gluten-free option to make that is so flavorful, serve with caramelized onions and ready in 30 minutes.

This is the viral Onion-Wrapped Burger from In-N-Out! But a homemade version that is still so delicious, flavorful and easy to make at home. Plus if you don’t live by the beloved fast food chain (like me), it’s a great way to satisfy the craving. The onions as the “buns” are caramelized to perfection and filled with flavor, cheese and juicy beef. And don’t skip on the sauce!

In-N-Out is known for their yummy burgers and animal style fries. They have such a good spread and something for everyone. The sauce they make is so yummy, not too thick and the pickle relish in it goes a long way. I love having it with burgers, fries and call me nuts – but dipping pickles in it, is SO good too.

This recipe is one of our latest obsessions after making it a few times now. It went totally viral on social media and for good reason. Sometimes when I see things go viral, I question if they are actually good. But this – wow!

I love that this recipe is a great way to switch things up from a lettuce wrap if you want a lighter or low carb and gluten-free option for a burger.

I can’t wait to hear what you think of this dinner. Such a comfort food that you will love!

What ingredients you need to make the Onion-Wrapped Flying Dutchman:

  • Mayonnaise – you can use any mayo you’d like! 
  • Pickle relish – this is a must add in the sauce!
  • Ketchup – I like to use unsweetened ketchup for no added sugar
  • White vinegar – you can also apple cider vinegar
  • Ground beef – I use 80/20 mix for ground beef typically. I like this ratio
  • Yellow mustard or your favorite mustard – yellow mustard is traditionally used but I love dijon!
  • 2 cheddar cheese or American cheese slices, cut into 8 pieces 
  • Avocado oil – or your go-to frying oil
  • Yellow onion – cut into circular slices. I like using yellow onion or sweet white onion for this. Red onion wouldn’t give it that sweet caramelized flavor 

How to make the Onion-Wrapped Flying Dutchman:

  1. First make the sauce/spread: mix together ingredients in a small bowl and set aisde
  2. Next make the caramelized onions: in a large skillet add oil then once hot add the onions and sprinkle with salt
  3. Cook for a few minutes until edges turn gold (I cook medium heat)
  4. Flip over gently and caramelized the other side for another 5-7 minutes
  5. Right before you take them off grill, add cheese to half of the grilled onions
  6. While onions cook, prepare the patties by dividing into 8 equal burger patties and season with salt and pepper
  7. Cook the burgers in same skillet as onions once done (add more oil if needed)
  8. As burgers cook, add a little mustard on top then flip over after it cooks for about 2-3 minutes
  9. After you flip the patties, add cheese on top of half of the patties and cook for another minute
  10. Add one patty without cheese on top of the cheese covered patty to create the double burger
  11. Gently transfer this stack onto the grilled onion and add a grilled onion with cheese on top as the bun
  12. Serve with the sauce and enjoy warm!

FAQs and tips on making In-N-Out’s Onion-Wrapped Flying Dutchman:

  • What kind of onions work best for this? I usually use a sweet white onion or yellow onion. I wouldn’t recommend red onion for this. The sweet and yellow onion have a naturally sweeter taste.
  • My onions are burning, what did I do? Caramelizing onions can be tricky! You don’t want to cook them on high heat or they will burn. Covering the onions and cooking on medium/low or even low heat works the best. If the onions are sticking, add a splash of water to the pan too.
  • What kind of cheese do you use? I like cheddar for this but you can use American or anything you want.
  • Can I save these for leftover? Yes of course. I do think they taste best fresh but you can warm up in oven if you have leftovers.
