Classic Beef meets Blue



  1. Preheat oven to 180˚C.
  2. To make the patties combine all ingredients in a large mixing bowl. Season well with salt and pepper. Shape into 4 patties about 11cm in diameter and place on a plate lined with paper towel. Cover with plastic wrap and refrigerate for 30 minutes.
  3. Line two trays with baking paper. Spread out the pancetta on one of the prepared trays and bake for 6-10 minutes or until crisp and browned.
  4. Heat a griddle pan until hot. Cook burgers for 2-3 minutes on each side then transfer then to the remaining tray, place in the oven and cook for 6-8 minutes or until done to your liking. In the last 2 minutes of cooking add a slice of Castello Burger Blue so it softens slightly on the patty.
  5. Meanwhile heat a tablespoon of olive oil in a large saucepan. Add the sliced mushrooms along with thyme leaves and season well with salt and black pepper. Cook over medium-high heat, tossing often for 3-4 minutes. Reduce heat to medium, add butter and cook for a further 1-2 minutes until butter is melted and mushrooms are coated. Remove from heat and add the créme fraiche.
  6. To assemble, add watercress to burger bun base, add tomato relish, burger pattie with Castello Burger Blue cheese slice, mushroom sauce, and top with burger bun lid.
