Instructions

Prepare the Onion Rings: Peel the large onion and slice it horizontally into thick rings, about 1/2 inch thick. Carefully separate the rings to use as the bun substitute for your burger. Set aside.
Form Beef Patties: Divide the ground beef into four equal portions and shape each into a patty slightly larger than the onion rings to ensure full coverage during cooking. Season both sides with salt and pepper to your preference.
Heat the Cooking Fat: In a large skillet over medium-high heat, add vegetable oil and butter if using. Let the butter melt and the oil heat until shimmering to prepare for pan-frying the patties.
Cook Patties: Place the beef patties into the skillet, cooking for about 4 to 5 minutes per side or until your desired doneness is reached. In the last minute of cooking, top each patty with a slice of cheese and cover the pan briefly to allow the cheese to melt perfectly.
Prepare the Sauce: While the patties cook, mix the mayonnaise, ketchup, mustard, pickle relish, and sriracha (if using) in a small bowl until well combined. Adjust sriracha amount to your preferred spice level.
Sear the Onion Rings: In the same skillet or a separate pan, briefly sear the onion rings for about 1 to 2 minutes per side until they soften slightly and get a bit of caramelization without falling apart. This enhances their flavor and texture as the burger bun.
Assemble the Burgers: On a clean surface or plate, place one onion ring as the bottom bun, add a cheese-topped beef patty, spread a generous amount of the prepared sauce over the patty, then top with another onion ring to complete the burger.
Serve and Enjoy: Serve the onion-wrapped Flying Dutchman immediately while hot for the best texture and flavor experience.

Notes

You can substitute white onion if you prefer a sharper onion flavor in your bun.
Using a fattier ground beef mix such as 80/20 ensures juicy, flavorful patties.
Butter added during frying enriches the patties but can be skipped for lower fat content.
Swap mayonnaise with Greek yogurt for a lighter, tangier sauce.
Low-sugar ketchup and Dijon mustard can be used to make the sauce healthier and more flavorful.
Adjust sriracha amount according to your desired spiciness or omit for a milder burger.
Searing the onion ring buns helps to soften and slightly caramelize them, enhancing texture and taste.
