Shallow fry: Heat ¼ inch of oil in a pan over high heat for 1 minute, then reduce the heat to medium and place the patties in the pan (making sure not to crowd the pan). Cook for 2 minutes then flip the patties and cook for another 1 to 2 minutes, or until each side is golden brown and the inside is at least 165F. (Once the oil is hot, you may only need to cook for 1 minute per side.)
