Preheat oven to 375°F and line a baking sheet with parchment paper.
In a large bowl, gently mix ground turkey, mayonnaise, Dijon mustard, Worcestershire sauce, minced garlic, kosher salt, and black pepper until just combined.
Divide into 4 equal portions and form ¾-inch-thick patties. Press a small indent in the center of each patty.
Heat olive oil in a cast iron skillet over medium-high heat. Sear patties for 2 minutes per side without moving to develop a crust.
Transfer patties to the prepared baking sheet and bake 12–15 minutes, or until an instant-read thermometer reads 165°F in the center.
Cool burgers completely on a wire rack for at least 30 minutes before storing.
Portion one patty per meal prep container. Store toppings (cheese, lettuce, tomato, onion, pickles) in separate compartments or small containers. Label with the prep date and refrigerate.
