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 the oven to 240°C/220°C fan-forced. Cut the kumara (unpeeled) into 1cm fries. Place the fries on an oven tray lined with baking paper. Season with salt and pepper and drizzle with olive oil. Toss to coat, then bake until tender, 20-25 minutes. TIP: Cut the kumara to size so it cooks in time.
While the fries are baking, finely chop the garlic. In a large bowl, combine the garlic, fine breadcrumbs (see ingredients list), egg, the salt, beef mince, Aussie spice blend and a pinch of pepper. Shape the beef mixture into patties, each a little wider than your burger buns. Transfer to a plate. You should get 1 patty per person. TIP: Make a shallow indentation in the centre of each patty to help prevent it puffing up as it cooks.
In a large frying pan, heat a drizzle of olive oil over a medium-high heat. Cook the beef patties until almost cooked through, 4-5 minutes each side. Transfer the beef patties to an oven tray lined with baking paper. TIP: If your pan is getting crowded, cook in batches for the best results!
Thinly slice the brown onion. Return the frying pan to a medium-high heat with a good drizzle of olive oil. Add the onion and cook, stirring, until softened, 5-6 minutes. Add the balsamic vinegar, warm water and brown sugar and mix well. Cook until dark and sticky, 3-5 minutes. Set aside.
While the onion is cooking, sprinkle the beef patties with the shredded Cheddar cheese. Bake until the cheese is melted, 2-3 minutes. Place the burger buns directly on the wire rack of the oven and bake until heated through, 3 minutes. While the burger buns are heating, thinly slice the tomato into rounds.
Slice the burger buns in half. Spread the base of the buns with garlic aioli. Top with a cheesy beef patty, some caramelised onion, tomato and mixed salad leaves. Serve with the kumara fries.
