Best-Ever Burgers with Caramelised Onion

I just love Pick & Pay's Fresh Living Magazines! This recipe is from the March edition and really lovely. The apple and mustard makes all the difference. 




Caramelized Onion:
1 TBS butter
1 TBS olive oil
1 large onion, sliced
1 TBS brown sugar

Patties:
500 g beef mince
1/2 onion, grated
1 apple, grated
1/2 cup instant oats
2 TBS wholegrain mustard
Salt and Pepper
1 TBS olive oil

To serve:
1 wheel Camembert cheese
Salad leaves
4 hamburger buns, halved and toasted

Serves 4

1. Melt butter with olive oil in a frying pan. Add onion and sugar, and fry over low heat until  onion is caramelized.
2. Mix mince, onion, apple, oats and mustard together. Season and shape into patties. Rest in the fridge for 20 minutes.
3. Rub patties with olive oil and cook over medium coals or on a heated griddle pan for 5 - 7 minutes on a side.
4. Cut Camembert into 8 slices.
5. Layer patties, caramelized onion, cheese and salad leaves on half the buns. Top with remaining buns. 

Notes:
You can use coconut oil instead of olive oil and Steer's / Wimpy mustard sauce instead of the wholegrain mustard sauce. 
You can also just use your own toppings such as pickles, cheddar cheese and tomatoes etc. as well.
