This was actually an attack on my life. The burgers came out raw. What kind of gas oven do they use in the BBC?

Excellent, made twice and a success both times. Good with red peppers in the mixture too!

Tried this out tonight and it was a resounding success. The only thing I would do differently is to take the burgers out a minute earlier and stick them on a griddle for extra yum. I also made a Harissa and mayonnaise dip for the sweet potato chips which was lovely. Will definitely be making again as its very quick and easy.

Tried this tonight but added a blue cheese centre and omitted the parmesan. Tasted very nice although I would probably use a binding agent e.g. an egg (or just a white to reduce the calories)/breadcrumbs. Tonight was the 'deconstructed' version adding some caramalised onions, gherkins and salad as a side plate without using the bun. Very nice indeed!

Really good recipe, trying to be a bit healthier but we still wanted a treat on a Saturday night! These were great. Used the extra lean beef mince and reduced the amount of parmesan just added pepper and extra chilli flakes for flavour! Grating the onion is a bit of a pain with a normal grater but other than that they worked fine. Made them into burgers and left covered in the fridge 30mins before cooking and they held together just fine, no egg or breadcrumbs required. Used a griddle pan to cook as found the oven (as suggested) didnt give them much colour. No oil needed to fry but the griddle pan made them nice and crispy and chargrilled on the outside. Served them up with a wholemeal seeded roll, lots of salad and the sweet potato oven chips as suggested. Really tasty and would definately recommend as a slightly lower calorie alternative to burger and chips!

Thanks guys. I will give this a go - parmesan, chilling beforehand, not moving them - the lot. I don't usually move them at all anyway. I do them on a ridged griddle and only go near them to flip them. And I will report back.

I think the parmesan is supposed to melt and glue them together. Served the spicy chips with sweet chilli sauce.

Naish, I make mine and put them in the fridge to rest for 30 mins at least, they used to fall apart and when I do this they don't, whatever type of mince I use. Also when you come to cook them just leave them for 2 mins, before you move them about.

I never have to use egg or breadcrumbs. Not sure why my burgers stay together but I think it's something to do with the level of fat content in the mince. Just shape the burger with the usual seasonings and there's no loss in taste!
