...just done the Mini Croque Monseiur (spelling ??).
They were OK - but if I was doing them again I would put the bread cases in the oven for 5 minutes or so before putting the fillings in.... so that they had a good time to crisp.
The eggs were a little over done in my oven at 15 minutes - but I admit that I did up the oven temperature to make the bread crisp.
I used a hollandise sauce rather than a bechamel one as I used the extra sauce to "drape" over the asparagus which I served as a side...
Would try again .....
