  • 400g of closed-cup white mushrooms
  • 1 white onion
  • 2 garlic cloves

Cut the baguettes lengthwise in half, then lightly brush them with butter.

Chop the onion, crush the garlic and grate the mushrooms on a large-mesh grater.

Heat the oil in a pan and fry the onion with garlic until softened and fragrant for about a minute on medium-high heat stirring constantly.

Add mushrooms and fry them together stirring occasionally for about 8-10 minutes until the water evaporates.

Season the mushrooms with salt, pepper and ground paprika as you desire.

Preheat the oven to 220C and prepare baking trays lined with aluminium foil.

Baguettes cut lengthwise with mushrooms

When the mushrooms are fried, remove them from the pan and place them evenly on the baguettes and sprinkle them with grated mozzarella cheese.

Finished Cheese and Mushrooms Open-Faced Sandwich


Instead of closed cup white mushrooms, you can use chestnut mushrooms, button mushrooms or any other variety of mushrooms.

If mushrooms are too small for grating, chop them finely into medium or long rectangles.

The most important part of this recipe is well-fried mushrooms.

For extra flavour and better presentation sprinkle with chives.
