Wash the mushrooms by drying them. Cut the larger ones into pieces.
In a casserole dish, brown the pressed garlic and the chopped shallot with the butter.
Add the chopped button mushrooms and sear them until they start to turn golden brown on each side, stirring them as little as possible.
Then add the chanterelles and cook for a few minutes.
Pour in the heavy cream and stir.
Arrange the mushrooms on the previously toasted slices of bread. Add salt and pepper
You can grate cheese on top.
Notes
Concerning cooking mushrooms (especially button mushrooms): it is better to let them cook without stirring them too much because otherwise they release water.
