Cheesy Beef & Creamy Pesto Burger

• Thinly slice brown onion. 
• In a large frying pan, heat a drizzle of olive oil over 
medium-high heat. Cook onion, stirring regularly 
until softened, 5-6 minutes. 
• Reduce heat to medium. Add the balsamic vinegar, 
brown sugar and a splash of water, then mix well. 
Cook until dark and sticky, 3-5 minutes. 
• Transfer to a small bowl.

• Meanwhile, in a large bowl, combine beef mince, 
fine breadcrumbs, the egg, tomato & herb 
seasoning and a pinch of salt. 
• Shape beef mixture into evenly sized patties
(1 per person) slightly larger than your burger buns. 
Transfer to a plate. 

• Wipe out frying pan and return to medium-high 
heat with a drizzle of olive oil.
• Cook beef patties until almost cooked through, 
4-5 minutes each side (cook in batches if your pan is 
getting crowded).
• Transfer beef patties to a second lined oven tray. 
Sprinkle over Cheddar cheese.
• Bake until patties are cooked through and cheese is 
melted, 3-4 minutes. 

• Meanwhile, halve bake-at-home burger buns
and bake directly on a wire oven rack until heated 
through, 2-3 minutes.
