Ingredients
Directions
Prepare
Wash, dry and peel the mushrooms.
For mushrooms au gratin, pick mushrooms of the same size, the cups being about two inches across.
Peel the mushrooms carefully without breaking them.
Cut out the stalks close down with a spoon.
Scoop out the inside of each cup to make it hollow.
Make the filling
Peel the stalks and chop them with the scooped mushroom, a piece of onion as big as the top of the thumb down to the first joint, and a brimming teaspoonful of chopped parsley.
Add a saltspoonful of dried thyme, or half that quantity of fresh thyme.
Fry all this in a frying pan in a little butter.
Add enough dried breadcrumbs, rubbed through a wire sieve, to make a moist paste.
Season the mixture with a little pepper, salt and lemon juice.
Bake and serve
Fill each cup with the mixture so the top is as convex as the cup.
Shake fine breadcrumbs over the top to give a golden-brown colour.
Pour a little oil into a baking tin and place the mushrooms in it.
Bake gently in the oven until the cup part is soft and tender, taking care they do not break.
Lift the mushrooms out carefully with an egg slice.
Place them on a dish and arrange crisp fried parsley around the edge.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms (in the method)
- Hollow caps hold the filling and become tender and soft as they bake.
- Dried breadcrumbs
- Absorb moisture from the filling to form a moist paste that holds its shape.
- Fine breadcrumbs (in the method)
- Browning on the surface gives the golden-brown colour.
- Onion
- Adds savoury aroma and flavour to the filling once fried in butter.
The step that matters
Bake gently until the cup part is soft and tender. Mushroom caps are delicate and lose structure if overcooked or heated too hard, so gentle heat softens them while keeping them whole.
