Herby Beef & Parmesan Crisp Burger

• While the fries are baking, pick and finely chop rosemary (see ingredients). 
• Thinly slice brown onion (see ingredients). 
• In a large bowl, combine beef mince, fine breadcrumbs (see ingredients), the salt, egg and half the rosemary. Season with pepper. 
• Shape beef mixture into evenly sized patties (1 per person), slightly larger than a burger bun. Set aside. 

Little cooks: Join the fun by helping combine the ingredients and shaping the mixture into patties!

• Place Parmesan cheese in even circles  
  (about the same size as your buns, 1 per person) on a second lined oven tray. 
• Bake until the cheese is golden and crisp at the edges, 6-8 minutes. 
• Remove from oven and set aside. 

TIP: Keep an eye on the Parmesan crisps, they can  burn quickly!  

TIP: The Parmesan crisps will harden as they cool. 

• While the crisps are baking, heat a large frying pan over medium-high with a drizzle of olive oil. Cook onion and the remaining rosemary, stirring, until softened, 4-5 minutes. 
• Add the balsamic vinegar, brown sugar and splash of water and mix well. Cook until dark and sticky, 3-5 minutes. Transfer to a small bowl. 

• Wipe out frying pan and return to medium-high heat. Cook beef patties until just cooked through, 4-5 minutes each side. 
• Meanwhile, halve bake-at-home burger buns and bake directly on a wire oven rack until heated through, 2-3 minutes. 
• Thinly slice tomato into rounds.
