Steak, Cheese and Onion Melt recipe


Preheat the oven to grill.

Heat the butter over a medium-low heat until it froths. Add the onions and cook, stirring frequently for about 20 mins, until the onion is very soft. Add the balsamic vinegar and brown sugar and cook for another 10 mins. Season as required.

Remove the Silver Fern Farms Beef Flat-Iron Steaks from the fridge and packaging and allow to bloom at room temperature for 10 mins.

Meanwhile, brush the Beef Flat-Iron Steaks with oil and season with salt and pepper. Heat a pan over a high heat. Add the Beef Flat-Iron Steaks and cook for 3-4 mins on each side. Transfer to a wooden board loosely covered with foil to rest for 5 mins before carving into thin slices across the grain.

Heat a little oil in a pan over a medium-high heat. Add the garlic, mushrooms, and thyme and cook for 5-10 mins until soft. Add the spinach and cook for another 5 mins until most of the moisture has been evaporated. Stir through the mustard and parsley, and season as required.

Lightly toast the Turkish bread and spread with mayonnaise and/or relish. Top with extra spinach leaves and then spoon some mushroom mixture on the base and add the cheese slices. Cook under the grill for a few mins to melt the cheese, then add some sliced Beef Flat-Iron Steaks, pickles (if using), and top with caramelised onions. To finish, sprinkle with chopped chives.
