Ingredients

  • 2 demi baguettes or similar long white sandwich rolls
  • 150 g cheese hard cheese like gouda, cheddar
  • 150 g button mushrooms
  • 50 g butter room temperature
  • 4 tbsp ketchup
  • 2 tsp chives minced
  • 2 tsp crisp fried onions optional

Instructions

  1. Halve the bread lengthways and place each half with the cut facing up. Spread the butter on all halves.

  2. Thinly slice the mushrooms and top the bread halves with an even layer of mushrooms.

  3. Grate the cheese and add it over the mushrooms making sure to cover the whole length of the bread.

  4. Toast in the preheated oven at 200°C (390°F) for 10 minutes, until the cheese melts and the bread gets nicely toasted.

  5. Squeeze the ketchup in a zig-zag pattern over the sandwiches, top with minced chives and crisp fried onions if desired.

Recipe Notes

  • Use the oven in conventional heating mode. This ensures a homogeneous distribution of the heat to perfectly toast the bread while melting the cheese. Broil/grill mode may brown the cheese too quickly.
  • The steam created by the melting butter and cheese will cook the thinly sliced mushrooms. This is why we are adding them raw.
  • The nutritional information provided is only an estimate and it is referred to the basic zapiekanka recipe. Additional toppings will increase the calorie tally.
