Tomato sauce is always classic on a burger, but for this delicious dinner we’ve combined two of our other faves; garlic aioli and caramelised onion. Plus melted Cheddar cheese, of course – this is a burger after all!

Preheat oven to 200°C/180°C fan-forced. Finely chop garlic. Thinly slice onion and tomato. Reserve some cos lettuce leaves (see ingredients) for the burgers, then shred the remainder. Transfer shredded lettuce to a medium bowl and set aside.
Little cooks: Don your goggles and have a go at peeling off the onion's outer layer!
In a large frying pan, heat a drizzle of olive oil over medium-high heat. Cook onion, stirring regularly, until softened, 5-6 minutes. Add the balsamic vinegar, water and brown sugar and mix well. Cook until dark and sticky, 3-5 minutes. Transfer to a small bowl.
In a large bowl, combine garlic, Aussie spice blend, fine breadcrumbs (see ingredients), egg, the salt, beef mince and a pinch of pepper. Shape mixture into evenly sized patties (1 per person) slightly larger than the burger buns. Transfer to a plate.
TIP: Make a shallow indent in the centre of each patty to help prevent it from puffing up as it cooks.
Return frying pan 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 lined oven tray. Sprinkle with shredded Cheddar cheese. Bake until the cheese is melted, 3-4 minutes. Meanwhile, place bake-at-home burger buns on a wire rack in the oven. Bake until heated through, 3 minutes. To bowl with the shredded lettuce, add a drizzle of olive oil. Season, then toss to coat.
Slice burger buns in half. Spread the bases with garlic aioli. Top with a cheesy beef patty, caramelised onion, tomato and reserved lettuce leaves. Serve with cos lettuce salad.
