Method

1. Cook the onion and garlic on medium heat for a few minutes in a frying pan with some oil until soft
2. Place the mixture in a large bowl and leave it for a short while to cool
3. Add the mince and egg to the bowl. Mix well and season with pepper and sage
4. Shape the mixture into 4 thick burgers – use some flour on your hands to prevent the meat sticking. Place on a covered plate or in a sealable container
5. Keep cool in the fridge until ready to cook
6. Cook the burgers in a hot frying pan with some olive oil for at least 10 to 12 minutes each side
7. Before serving, ensure that the burgers are cooked thoroughly. Use a meat thermometer to check they are at least 75ºC or cut into them with a clean knife and check that they are piping hot all the way through, there is no pink meat remaining and that the juices run clear. Learn more about how to use a meat thermometer.
8. When cooked, serve the burger immediately in the bun and dress as desired
