Remove the chicken fillets, which can also be cooked in the same way.
Lay out each chicken breast on a flat surface and bash with it with a meat tenderiser or a rolling pin so that the thickest part flattens and the whole breast fillet has an even thickness.
Season both sides of the breast with sea salt and freshly ground black pepper.
Dredge both sides of each breast in plain flour and shake off any excess.
Put a wide pan on a medium heat and add the butter with a drizzle of olive oil until the butter starts to foam (but do not let it burn)
Add the chicken breasts, being careful not to overcrowd the pan.
Cook for 4-5 minutes until the first side of each breast has taken on a golden brown colour and then turn onto the other side. Cook for another 8-10 minutes until cooked through.
Remove from the pan and allow to rest for 5-10 minutes and serve.
Notes
Use a meat thermometer to check when the chicken is done. I take the chicken breasts out of the pan when they reach 72°C, and they are perfectly cooked after they have rested.
Remove the chicken fillets from the breasts. This can also be lightly flattened and cooked in the same way, They are particular popular with the kids.
The butter gives the chicken fantastic flavour, but don't forget the extra virgin olive oil as this stops the butter burning.
I prefer to salt the chicken breasts directly, as I find adding it to the flour doesnt season the chicken enough for my taste.
You can also use deboned chicken thighs using the same method, which also taste great.
