If you’ve spent any time scrolling food videos lately, chances are you’ve seen it: thick caramelized onion slices replacing buns, hugging juicy beef patties and molten cheese in a gloriously messy stack.

Inspired by the legendary Flying Dutchman Burger popularized by In-N-Out’s not-so-secret menu, this version leans fully into the bunless lifestyle by using sweet, deeply caramelized onions as the “bread.” The result? A burger that’s indulgent, savory, naturally gluten-free, and surprisingly low in carbs — without sacrificing flavor.

It’s a technique-driven burger that celebrates texture: soft, jammy onions on the outside, crisp-edged beef patties in the middle, and cheese that melts into every crevice. Whether you’re following a low-carb diet, avoiding bread, or simply craving something different, this burger delivers.

Tips for achieving restaurant-quality burger patties
Variations, serving ideas, and cultural context

Let’s dive into the burger that proves you don’t need bread to build something unforgettable.

What Is a Flying Dutchman Burger?

The original Flying Dutchman Burger is a minimalist creation: two beef patties and two slices of cheese, no bun. It’s beloved for its simplicity and bold flavor. The viral version elevates the concept by adding caramelized onion slices as a bun substitute, creating structure, sweetness, and visual drama.

Onions act as:

A natural sweet counterbalance to salty beef
A soft-but-sturdy exterior
A moisture barrier that keeps everything juicy

This onion bun burger isn’t pretending to be bread — it’s better in its own way.

Why Onion Buns Are Genius

Caramelized onions are rich in natural sugars. When cooked slowly, they transform into something deeply savory and sweet, with a silky texture that wraps around the burger instead of competing with it.

Benefits of onion buns:

Low carb and gluten-free
Naturally flavorful — no extra sauces required
Visually striking and restaurant-worthy
Hold up surprisingly well when sliced thick

The key is patience. Rushing onions leads to bitterness; slow cooking creates magic.

Ingredients

Use high-quality ingredients — with so few components, each one matters.

Large yellow onions (sliced into thick rounds)
Ground beef (80/20 recommended)
American cheese slices (or cheddar if preferred)
Butter or beef tallow
Salt
Freshly ground black pepper

Instructions

Prepare the onions
Peel the onions and slice them into thick rounds, about ½ to ¾ inch thick. Keep the rings intact — these will act as your buns.
Caramelize the onion buns
Heat a skillet over medium-low heat and add butter. Place onion slices in the pan and cook slowly, 12–15 minutes per side, until deeply golden and soft. Season lightly with salt. Remove and set aside.
Form the burger patties
Divide ground beef into equal portions and gently form patties slightly wider than the onion slices. Season generously with salt and pepper.
Cook the patties
In the same skillet (or a grill pan), cook patties over medium-high heat for 2–3 minutes per side until browned and cooked to your preference.
Add cheese
Place a slice of cheese on each patty during the final minute of cooking. Cover briefly to help it melt.
Assemble the burgers
Place one onion slice on a plate, top with a cheesy patty, stack a second patty if desired, then cap with another onion slice.
Serve immediately
Enjoy hot while the onions are soft and the cheese is gooey.

Pro Tips for the Best Onion Bun Burger

Choose the right onions: Yellow onions caramelize best. White onions cook faster but are less sweet.
Don’t rush the heat: Low and slow onions = sweetness, not bitterness.
Use American cheese: It melts smoothly and coats the patties perfectly.
Press gently: Overworking the beef leads to dense patties.
Serve immediately: Onion buns soften as they sit — best enjoyed fresh.
