5: In a large frying pan or saucepan over high heat, melt 50 g semi-salted butter and when it has melted and begun to brown slightly (it's a beurre noisette) add the chopped shallot and cook for 1 minute, stirring.
6: Add the endives and mix well. Cook for approx. 3-5 minutes, until just tender.
You can also bake it in individual cassolettes rather than in a traditional oven dish. When you prepare the béchamel sauce, you can add a little of the same cheese as in the recipe at the end of cooking, for an even more pronounced taste.
