01 -
In a big mixing bowl, toss together minced beef, onion slices, breadcrumbs, blue cheese chunks, and a beaten egg.
02 -
Add Worcestershire sauce, mustard, parsley, salt, pepper, and a couple shakes of Tabasco to the beef combo.
03 -
Carefully knead everything by hand until it feels well-mixed but don’t overdo it.
04 -
Divide mixture into 6 equally thick portions, gently shaping them into patties without compressing the meat too much.
05 -
Wrap patties in plastic wrap and chill them in the fridge for a firm texture—exactly 30 minutes.
06 -
Warm up a skillet on medium-high heat until it's hot enough to make pancetta sizzle.
07 -
Sear pancetta slices until they’re delightfully crispy, then move onto a dry plate.
08 -
In the same pan, cook burgers for around 3-4 minutes on each side over medium heat.
09 -
As the burgers cook, softly press with a spatula to ensure the surface cooks evenly.
10 -
Mix sour cream, crumbled blue cheese, chopped chives, olive oil, and a splash of Worcestershire together in a small bowl.
11 -
If the sauce feels a bit too thick, stir in more sour cream until you can spread it easily.
12 -
Lightly toast the cut sides of the brioche buns until beautifully golden.
13 -
Generously slather onion chutney on the bottom part of each toasted bun.
14 -
Layer a cooked burger patty on top of the chutney-covered bun.
15 -
Pile on a piece of crisp pancetta, ladle over some blue cheese sauce, and top it off with the other half of the bun.
