Step-by-Step Instructions

Caramelize the Onion Buns

Slice onion into four thick rounds. Brush with olive oil, Worcestershire, seasoning, and brown sugar. Cook in a skillet over medium-low heat for about 10 minutes per side until deeply browned and tender but intact. Set aside carefully—they become delicate when soft.

Prepare the Patties

In a bowl, season ground beef with Creole seasoning. Divide into four equal balls and smash into thin patties.

Sear the Burgers

Heat skillet over medium-high. Cook patties 2–3 minutes per side until a crust forms and internal temperature reaches 160°F.

Melt the Cheese

Place one slice of American cheese on each patty during the final minute of cooking. Allow to melt fully.

Make the Sauce

Whisk together mayonnaise, relish, Dijon, Worcestershire, sugar, garlic powder, onion powder, smoked paprika, Creole seasoning, and cayenne until smooth.

Assemble the Burgers

Place one caramelized onion round on a plate. Top with a cheesy patty, spoon sauce over it, then finish with another onion round as the top “bun.”

Serve Immediately

Serve hot with extra sauce on the side.

Recipe Notes & Tips

• Cook Onions Slowly – Low heat prevents burning and ensures tenderness.
• Use 80/20 Beef – Leaner blends may dry out.
• Smash Thin for Crust – Thin patties maximize surface browning.
• Handle Onions Gently – They soften significantly during cooking.
• Taste the Sauce First – Adjust sweetness and heat to preference.
