Cook the caramelised onions

Learn to caramelise red onions in more detail, but for a quick explanation, here’s how: Slice 2 red onions and separate the rings > add a tablespoon of olive oil to pan and cook onions on medium heat for 5 minutes > then add tablespoon of brown sugar and balsamic vinegar – mixing thoroughly.

Then reduce to a low heat and continue to toss the red onions for up to 25 minutes until the onions have browned and the texture looks sticky. When done, add to bowl and keep warn well you cook the steak and prepare the ciabatta.

How to cook the steak

Baring in mind we’re using a medium size rump steak, cooking time can vary but use our timing as a target. To cook the steak, we first took it out of the fridge for at least an hour to bring it to room temperature – then season with salt and pepper.

Then with a frying pan we brought it up a to high heat with a tablespoon of olive oil, then seared both sides for no more than a minutes on each side – well using a spatula to press down so the steak sears evenly.

Then add to a preheated oven – GAS MARK 4 – for 8 minutes, then remove, and cut 2mm slices.

Prepare the ciabatta

Not much to do to prepare the ciabatta, simply cut in half like you do with any sandwich and spread in butter, optional. But if you grill on the frying pan before cooking the steak, you’ll create a nice seal well improving the taste.

Either way, it’s probably best to heat through the ciabatta for best results. Well the steak is cooking in the oven as explained above, for the final 4 or 5 minutes of cooking time, add the ciabatta to the oven.
