While the origin of the hamburger is murky, the classic sandwich - AKA the hamburger - has been a hit since its conception. It’s been such a hit that Australia is paying homage to the delicious dough double-decker this Saturday May 28th, with National Burger Day! To celebrate this momentous occasion, we’ve cooked up our favourite Marley Spoon burger - the Double Cheese Burger served with Sweet Potato Fries. We’re not one to keep our favourite recipes to ourselves, so go and round up all of your family and friends and get cooking! Double Cheese Burger and Sweet Potato FriesWhat you’ll need:

  • 400g sweet potatoes
  • 1 red capsicum
  • 5g oregano
  • 1 shallot
  • 125g cherry tomatoes
  • 60ml red wine vinegar
  • 125g haloumi
  • 2 burger buns
  • 40g rocket
  • Extra virgin olive oil
  • Salt and pepper
  • 2 tbs sugar
  • 35g plain flour

Method 1. Preheat oven to 220C. Peel the sweet potato and cut into 2cm thick wedges. Place on a baking tray lined with baking paper. Drizzle with oil, season with salt and toss to coat. Roast for 20 minutes or until golden and tender. Preheat the grill to high. 2. Meanwhile, cut four ‘cheeks’ off the capsicum and set aside. Finely chop the remaining flesh to be used in the relish, discarding seeds and white membrane. Pick the oregano leaves and coarsely chop. Finely chop the shallot. 3. Heat 1 tbs oil in a saucepan over medium-high heat. Cook tomatoes, shallot and chopped capsicum for 3 mins, or until slightly softened. Using the back of a fork, lightly squash the tomatoes. Stir in oregano, vinegar, 2 tbs sugar and ¾ tsp salt. Cook for a further 5 mins or until vegetables have softened. 4. Meanwhile, heat 2 tsp oil in the frypan over medium-high heat. Cook the capsicum cheeks for 3 mins each side or until lightly charred and cooked through. Remove from pan and keep warm. 5. Meanwhile, cut the haloumi into four steaks. Place the flour on a plate, then lightly dust the haloumi steaks, shaking off excess. Heat 3 tsp oil in the same frypan over medium-high heat. Cook for 1 min each side, or until golden. Remove from pan and keep warm. 6. Halve burger buns and toast under grill. Spread relish on each side of burger bun. Divide rocket between burger bases. Top each base with a haloumi steak, 2 capsicum cheeks, then remaining haloumi steak. Top with burger lids and serve with wedges.
