Mushroom lasagne

Honestly, I was not impressed with this lasagne.  It simply did not hold together to look anywhere like the picture, and I'm not sure why.

The magazine version:

Then mine:

The mushroom mixture was thick and tomatoey.

I went the whole way, and simmered the milk for the bechamel with half an onion, some thyme and a bay leaf.

But still it looked sad.

Not brown enough on top, and very runny (looked soupy and ugly on the plate, so I didn't take a picture!)
