egg free beef burgers that don't fall apart?

[mousymouse]

made some nice tasting ones yesterday.
usually I use 1 egg per pound of beef but didn't use egg yesterday as had guests that couldn't have eggs.
they held together in the pan but fell apart when eating.
I used
1kg ground beef
2 onions very finely chopped in a food proccessor
salt pepper
herbs
2 table spoons flour

you need to do more squishing if you don't use egg.

just moulding them into shape and patting them is not enough... lots of squishing

[midoriway]

Putting the onions in the food processor would have released a lot of water, I wouldn't have done that, just chopped with a knife on a board would be fine. And like cat says, you work the meat like play-doh, and they should be fine without egg.

I never use egg.... in addition to more squishing, make ahead and put in the fridge.

[mousymouse]

I squeezed the water out of the onions after chopping them up...have a child who likes the flavour but not the texture...

will squish/knead the meat more next time. tastewise they really don't need egg but I suppose if you want to bulk them out with more flour or brad if would be essential.

[CogitoErgoSometimes]

You have to massage the meat.... squish it about, knead it, mix & stir it really well.... or mix the burgers in your food processor using the dough hook. This makes the sticky proteins in the meat come to the surface and that holds the meat together.

Frying the onions before adding to the mix helps get rid of the moisture. And agree that you need to squish too.
