Cheesy Beef Burger & Truffle Mayo

• While the fries are baking, pick and finely chop 
rosemary leaves. 
• Thinly slice brown onion. 
• 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. The Parmesan 
crisps will harden as they cool. 

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

• While the crisps are baking, heat a large frying 
pan over medium-high with a drizzle of olive oil. 
Cook onion and remaining rosemary, stirring, 
until softened, 4-5 minutes. 
• Add the balsamic vinegar, brown sugar and 
a 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. 
• Meanwhile, thinly slice tomato.
