Please note, the amounts are approximate. You may want to add more or less butter or vegan butter. You could also use more or less herbs or omit all the herbs. The main idea is to use enough fat in the beginning and in the end and also not stir as described below!
How to cook mushrooms
Wash and dry the mushrooms. Mushrooms need to be completely dry. Slice the mushrooms
Heat enough butter or vegan butter in the pan to cover the bottom. About 2 teaspoons.
Heat the pan to a generous medium to medium-high heat.
Add the mushrooms to the melted butter, stir and then let the mushrooms cook without stirring.
Let mushrooms cook without stirring.
Let mushrooms cook without stirring!!!
Once mushrooms reduced by almost half and you start to see golden edges and there's no more steam, no more liquid and they sound and look like they are going to start burning soon, then add the rest of the butter or vegan butter (2 teaspoons) and stir/flip the mushrooms.
Let the mushrooms cook again without stirring. This will take less time than the first part.
Add salt, pepper in the end.
Add herbs if using. I prefer lots of fresh dill, but you can add parsley or thyme.
