This is a small snack or a lovely little starter. Feel free to use this recipe with any good eating mushrooms you can get your hands on. I've noticed that it seems to be compulsory around the world to cook wild mushrooms simply, in a pan with butter, oil, garlic, some sort of herb, salt, and pepper. I can't argue with that method - it does give delicious results - but the nice thing about this recipe is that with all the juices that naturally cook out of the mushrooms and mix with the butter, you only need to add a touch of cream to get a sauce that gives the illusion of being really creamy when it's actually not. I think this is best served bubbling in the pan with some chunks of bread, but it could also become a layer in a lasagne, be spooned over steak or pork, get tossed with pasta or be paired with beef strips and rice for a sort of stroganoff. What a treat.
Preheat your oven to its lowest setting and pop the loaf of bread in to warm through.
Spend a few minutes gently brushing along the underside of the mushrooms to get rid of any bugs and dirt that might be hiding there. This is well worth the effort. Finely chop your parsley, stalks and all, reserving a few of the leaves.
Put the butter into a large hot pan and as soon as it starts to melt add a drizzle of olive oil, the mushrooms, sliced onion, and a good pinch of salt and pepper. Stir everything around and cook for about 8 minutes, or until the onions have softened and the mushrooms are starting to caramelize and take on colour.
Add the chopped parsley, then pour in the cream. Continue to stir and cook for another minute, until the cream has come to the boil, then turn down the heat and simmer for a minute before removing from the heat. Add a good squeeze of lemon juice, have a taste, and add more salt, pepper or lemon juice if it needs it.
Take your bread out of the oven and tear it into big chunks. Divide the mushrooms among the plates and scatter over the reserved parsley leaves. Serve with the chunks of bread on the side to mop up all the creamy mushroomy juices, and tuck in!
