Place cooking oil in a large skillet with a lid and set aside.
Mince the onion.
In a large bowl, mix the ground turkey, onion, Panko and seasonings. It is preferable to use your hands and don't over mix.
Divide the turkey mixture in half and then divide each half into 2 or 3 parts. I did 3 but if you want bigger burgers feel free to do 2.
Roll each portion into a nice tight ball. The meat balls should be about the size of a tennis ball or maybe a little larger.
Press the turkey portions out by hand into discs that are about 1 inch thick. They can be a little less if you like thinner burgers. I wouldn’t go any less than ½ inch.
Heat the oil in the skillet over medium high heat until hot but not to the point of smoking.
Carefully, place the turkey patties in the hot oil. Watch out for the splatter.
Cook on the first side for 3 to 4 minutes. The bottom will turn a dark brown.
Flip the burgers and cook the second side for a minute or so. Turn the burner down to low heat and cover. Cook the burgers undisturbed for about 4 minutes. Uncover and check to see if they are cooked through. You can use a meat thermometer to check for doneness if you want. The middle will need to read 165 degrees.
When fully cooked, remove the patties to a platter.
Place these patties on some nice soft buns, toasted or not. Add your favorite cheese and toppings.
