Swedish Meatball Burgers

Heat a splash of oil in a frying pan over low heat and add the onions and a pinch of salt. Cook until soft and caramelised, stirring often.

Combine all the ingredients for the burgers with some salt and mix well. Shape into 4 patties and refrigerate while you make the sauce.

Preheat two gas burners on the Jupiter Outback BBQ and set the heat to medium-low. Place the burgers onto the grill and cook for 4 minutes each side, or until cooked through.

Make the sauce by melting the butter in a saucepan over medium-low heat. Once foaming, add the flour and whisk.

Continue whisking until the roux becomes a light caramel colour.

Slowly add the beef stock in small additions, whisking to ensure each addition is fully absorbed before adding the next. Once all the stock is added, remove from the heat and add the sour cream and seasoning.

To build the burgers, add a layer of caramelised onions, top with the patties, a slice of the cheese and finally some of the sauce.

Of course, this recipe could be used to make a more traditional Swedish meatballs. Simply shape the burger mix into smaller meatballs and fry to cook, then serve with the meatball sauce and lingonberry jam.
