Crème fraiche dressing

Mushroom sandwich
  • Melt butter in a frying pan over high heat, but do not let it brown. Sauté onion and thyme sprig for about 2 minutes.
  • Add mushrooms and fry for about 5 minutes until golden and dry.
  • Add garlic and salt and fry at medium heat for about 2 minutes. Remove the thyme sprig.
  • Spread the bread slices with butter on one side.
  • Arrange the bread, butter side out, with cheese, mushroom mixture, and crème fraiche dressing.
  • Heat a toasting machine to a high temperature and toast the sandwich for about 5 minutes until golden and the cheese is melted. Serve warm.

If you have any, opt for leftover bread for this mushroom sandwich. It soaks up liquids better and keeps its shape when toasted, resulting in the best mushroom sandwich possible.


Make sure to clean the mushrooms thoroughly before use, as they tend to have minor blemishes or contain dirt.

Make a savoury mushroom sandwich

Making a savoury mushroom sandwich is about choosing the right combination of flavours and textures; in this recipe, you get exactly that. Fried in butter with onion and thyme, the mushrooms transform into tender little pieces of utter delight, waiting for you to bite into the sandwich. Their soft texture creates an interplay of textures with the crispness of the toasted bread and the mushy melted cheese.

Enjoy the spicy kick from jalapeño-flavoured cheese

The spicy Havarti cheese adds a boost to the creamy mushroom sandwich. It does not overpower the savoury mushrooms; it only accentuates their richness and ensures a pleasant flavour kick.

To further complement the spicy addition, the creamy and tangy crème fraiche dressing serves as a refreshing counterpoint to the intensity of the jalapeño-flavoured cheese.

A zesty finish with crème fraiche dressing

A zesty finish from the crème fraiche dressing guarantees the perfect combination of flavours in your mushroom sandwich. The creamy tang from the crème fraiche is enhanced by a hint of freshly squeezed lemon juice that helps balance the savoury mushrooms and the heat from the cheese. The dressing binds the mushroom sandwich together, allowing every bite to travel from rich and savoury to spicy and refreshing. The dressing is an easy-to-make addition that pays off as the final flourish of flavour to your sandwich.

Experiment with the recipe

A simple mushroom sandwich like this one leaves plenty of room to experiment with the ingredients. While the jalapeño cheese is full of flavour, you might want an even more pronounced spice in your sandwich. If so, add fresh or powdered chilli to the mushroom mixture.

On the other hand, if you prefer a milder touch to your mushroom sandwich, you can switch out the spicy cheese with a regular one of your choice. The melted cheese will still be a great addition to the flavour base. Similarly, you can experiment with different mushrooms, such as portobellos or oyster mushrooms. The type of mushroom you choose will affect the texture of the sandwich.

Try adding fried bacon to the mushroom sandwich. The bacon will impart its distinctive smoky aroma alongside its salty flavour. Its crispy texture will also enhance the overall experience.
