Before giant, double-decker burgers flooded our Instagram feeds, there were sliders—tiny, smashed patties that packed a powerful flavor by simply using the combination of meat, cheese, and onions.

Small, but mighty, sliders shaped the burger world thanks to an innovative cooking method. Once the patties are smashed and covered with onions, they’re covered by parchment paper, creating a steam tent that perfumes the burger with onion aroma and unlocks incredible flavor.

Sliders are still a prevalent style in Northern New Jersey, and with the help of Alvin’s tips, you can recreate this magic in your own home.
