Make your own Onion-Wrapped FLYING DUTCHMAN burger at home – it’s even better! If you’re a fan of grilled onions like me, you’ll love giving this a try. It’s so delicious!
Try making the viral Onion-Wrapped Burger from In-N-Out at home, and trust me, it’s even better! No bread buns, but you won’t miss them. The onions are perfectly caramelized, bursting with umami flavor – way better than lettuce or tomato-wrapped burgers!
Every burger joint has its own “secret formula” for burger sauce, but many use a similar base of mayo, ketchup, and mustard. In my opinion, In-N-Out has the best spread compared to places like Shake Shack. It’s not too thick, giving you the perfect balance of tanginess from pickle relish and sweetness from ketchup, cutting down on the heaviness of the burgers.

Instructions
**Make the Spread:**
- In a small bowl, mix mayonnaise, relish, ketchup, sugar, and vinegar. Set aside.
**Prepare the Patties:**
- Weigh out 8 portions of 3 to 4 oz of ground beef. Gently flatten each patty, sprinkle with salt and pepper on both sides, and set aside.
**Caramelize the Onion Buns:**
- In a pan over medium to medium-low heat, add vegetable oil. Cook onions with sugar and salt until golden. Add cheese to half the grilled onions.
**Cook and Assemble the Burger:**
- In a skillet over medium-high heat, add vegetable oil and/or butter. Cook patties, optionally spreading mustard on the raw side. Flip, add cheese, and cook for 1 more minute. Create a double double burger by stacking a patty without cheese on top of a patty with cheese. Transfer onto a grilled onion and top with another grilled onion with cheese.
- Serve with the spread and enjoy your warm, homemade creation!
