Ingredients
Serving Size: 4 bombs
For the Caramelized Onions
1 large yellow onions, thinly sliced
2 tbsp butter
1 tbsp olive oil
Salt
Optional splash of Worcestershire
For the Burger
4 burger patties (cut in half and rolled into balls). You will have 8 smaller patties
Salt and pepper, to taste
16 slices American cheese
For Burger Sauce
1/2 cup mayo
2 tbsp ketchup
1 tbsp mustard
2 tbsp finely sweet relish
1 tsp garlic powder
1 tsp paprika
1 tsp white vinegar
For the Assembly
2 sheets puff pastry, thawed
1 egg (for egg wash), plus splash of water
Sesame seeds
Instructions
Caramelize the onions
Heat butter and olive oil in a pan over medium low heat. Add sliced onions with a pinch of salt and cook slowly, stirring occasionally, for about 25 to 35 minutes until deeply golden and jammy. Add a small splash of Worcestershire if using. Set aside and let cool completely.Make the burger sauce
In a bowl, mix mayo, ketchup, mustard, relish, garlic powder, paprika, and white vinegar. Stir until smooth and refrigerate. Reserve half for dipping later.Cook the smashed patties
Heat a cast iron skillet over high heat until very hot. Add the beef balls and smash them thin. Season with salt and pepper. Cook for 1 to 2 minutes until crispy, flip and cook another 1-2 minutes. They will cook more in the oven so no need to over cook here. Remove from heat.Prep the pastry
Lightly flour a surface and roll the puff pastry slightly larger, about 10 to 12 inches. Place it on a parchment-lined baking sheet. Use a bowl to cut a circle out of the puff pastry. Depending on how big your patties are, you’ll want a big enough circle to wrap around. Mine was around 8inches.Assemble
Add burger patty, 2 slices of American cheese (I cut my slices so they were a little smaller), Add some onions, a dollop of sauce, another patty, and another 2 slices of cheese.Wrap
Fold the puff pastry up and over the burger, sealing all edges tightly. Flip so the seam is on the bottom.Finish
Brush the entire pastry with egg wash and sprinkle generously with sesame seeds.Bake
Bake at 425°F for 15 to 20 minutes until the pastry is deeply golden brown and puffed.Rest and serve
Let rest for 5 to 7 minutes before slicing. Serve warm with the reserved burger sauce on the side.
