Cheddar-Stuffed Turkey Burger With Avocado

Step 1

Combine the turkey, salt, pepper and parsley in a large bowl and mix with a fork or clean hands to season evenly. Add the egg and milk and stir to combine.

Step 2

Divide the meat into four portions with damp hands and gently pack into four round patties, about 3/4-inch thick. (It will feel very sticky because of the egg, which helps burgers hold their shape as they cook.) Place burgers on a parchment-lined baking tray or plate. Cut the butter into slices and 1 slice of the cheese into 4 thin squares, about 1 inch across. (The butter and cheese should be the same size.) Press a piece of each into the center of each burger. Shape the meat around it to cover across the top. Refrigerate for 10 minutes while you prepare the griddle.

Step 3

Heat a flat-top griddle or cast-iron skillet over medium-high heat. Add enough butter just lightly coat the griddle or pan. Add the burgers to the griddle and cook until browned and just cooked through and a thermometer inserted into the meat (not the cheese in the center) reaches 165 degrees, about 4 minutes per side. In the final 2 minutes of cooking, add the remaining 4 cheese slices to the burgers, to melt.

Step 4

Remove the burgers from the heat and layer onto the buns with the avocado and any other burger toppings you desire. Serve warm.
