Method
Lamb Patties
Mix
In a medium bowl, combine the ground lamb, finely chopped shallot, parsley, mint, Dijon mustard, Worcestershire sauce, salt, and black pepper. Mix gently with your hands or a fork until ingredients are evenly distributed — avoid overworking the meat to keep patties tender.
Form
Divide the mixture into two equal portions. Shape each portion into a round patty about 2.5–3 inches (6–7 cm) in diameter and roughly 1/2 inch (1.2 cm) thick. Make a very slight indentation in the center of each patty with your thumb to help them cook evenly and resist doming.
Cook
Heat a skillet (cast-iron preferred) over medium-high heat. Add 1 teaspoon neutral oil and swirl to coat. When the pan is hot and shimmering, add the patties, leaving space between them. Cook for 3–4 minutes per side for medium (adjust 2–3 minutes for medium-rare or 4–5 minutes for medium-well), turning once. Do not press down on the patties. Internal temperature target: 145°F (63°C) for medium, or adjust to preference. Remove cooked patties to a plate and tent loosely with foil to rest for 5 minutes.
Caramelized Onions
Sweeten & Finish
When the onions have reached a deep golden color (about 12–18 minutes total, depending on heat and pan), sprinkle the brown sugar over them and stir to combine. Cook another 1–2 minutes, then add the balsamic vinegar and stir to deglaze the pan and concentrate flavors. Season with 1/8 tsp black pepper. Remove from heat and keep warm.
Assembly & Garnish
Spread Mustard
Spread 1/2 teaspoon of whole grain mustard on the bottom half of each toasted bun, reserving the remaining half teaspoon for the other bun if preferred.
Assemble
Place one lamb patty on each mustard-smeared bottom bun. Top each patty with a generous spoonful (about 1–2 tablespoons) of the warm brown sugar–caramelized onions. Add a small handful of baby arugula or microgreens if using, then cap with the top bun.
