ingredients

  • 30 - 100 g Castello® Creamy White
  • 1 sheet (large) puff pastry or 3 sheets (75g each)
  • 1 egg, beaten
  • 10 cherry tomatoes
  • 1 medium red onion
  • 3 tbsp parsley, finely chopped
  • fresh thyme leaves
  • 1 tsp olive oil
  • salt and freshly ground pepper

preparation

1. Cut the red onion into slices and place in a mixing bowl with the olive oil, salt and pepper.

2. Cut the puff pastry into 3 even-sized rectangular pieces, carve a square pattern, 1cm from the edge, on the surface of the dough, make sure not to cut through the dough. This will create a puffy crust and a flatter centre.

3. Brush the pastry twice with the beaten egg.

4. Keeping inside your square, spread the onion out. Cut your left over cheese into slices and spread out evenly on top of the onion.

5. Bake the puff pastry in the oven at 200°C for 15 minutes (convection oven).

6. While in the oven cut cherry tomato into quarters and mix with olive oil, parsley and season with salt and pepper.

7. When the puff pastry is cooked, divide the tomatoes out on top and serve right away on a serving tray or wooden board.

Serving Suggestion

Serving Suggestion

If you have leftover Creamy White and puff pastry, you can use it to make dessert. Instead of a cheese and onion tart, you can make a delicious dessert with most of the same ingredients. Prepare the puff pastry as described in this recipe and place thin slices of pear on top instead of onions followed by slices of cheese. You can drizzle a bit of maple syrup and sprinkle with chopped walnuts for some extra crunch and sweetness. Bake in the oven for 15 minutes at 200°C.
