In a medium bowl, gently combine the ground turkey thighs, garlic powder, onion powder, chopped fresh parsley, Dijon mustard, mayonnaise, black pepper, kosher salt, and smoked paprika.
Use your hands, but be gentle! Mix just until everything is combined. Overmixing can lead to tough burgers, and we definitely don't want that.
Divide the mixture into four equal portions. Shape each portion into a patty about 1 inch thick. Try to make them slightly wider than your burger buns, as they'll shrink a bit when they cook.
Heat the olive oil in a large skillet over medium-high heat. You want the pan to be nice and hot before the burgers go in – this helps create a beautiful sear.
Carefully place the patties in the hot skillet. Cook for about 4-5 minutes per side, or until they are nicely browned on the outside and cooked through in the center. Turkey burgers should reach an internal temperature of 165°F (74°C). Don't press down on the burgers with your spatula while they cook – that pushes out all the delicious juices!
Once cooked, transfer the burgers to a plate and let them rest for a minute or two. This allows the juices to redistribute, making them even more tender and delicious.
Pile those beautiful, juicy turkey burgers onto your favorite buns with all your go-to toppings. Lettuce, tomato, onion, pickles, cheese... the possibilities are endless! Get ready to dig in!
