Heat a large frying pan over high heat then add a tablespoon or two of olive oil.
Fry the mushrooms in batches, until well-browned all over.
Add all the mushrooms back to the pan with their resting juices and add the garlic, herbs and chilli flakes. Cook for 1-2 minutes.
Add the butter and lemon juice and stir well while the butter is melting to create a creamy sauce then take off the heat. Season to taste.
Serve the creamy mushrooms on toast smeared with cream cheese (optional).
