Halve the fennel bulbs and cut out the stalk. Then cut the tuber halves into 1 cm thick slices. Cook in salted water for about 10 minutes.
In the meantime, oil a baking dish with 2 tablespoons of olive oil. Strain the fennel and arrange it in the baking dish so that it overlaps. Put 4 tablespoons of breadcrumbs, 4 tablespoons of parmesan, 1 pinch of nutmeg, salt and pepper in a bowl and mix well. Spread evenly over the fennel and drizzle 2 tablespoons of olive oil over it. Bake in the oven at 180 degrees for about 20 minutes until the surface is browned.
Variations:
Mix in with the breadcrumbs: 1/2 bunch of parsley cut into small pieces, some capers soaked for a short time, 1 finely chopped clove of garlic.
