Set up your kitchen space with a clean cutting board, mixing bowl, and all your ingredients. Preheat your grill or frying pan over medium-high heat.
In a large mixing bowl, combine the ground turkey with minced garlic, salt, pepper, Dijon mustard, Worcestershire sauce, fresh herbs (parsley, basil, scallions), smoked paprika, and Parmesan cheese. Use your hands to blend everything until fully incorporated. Avoid overmixing, as this can lead to tough burgers.
Divide the mixture into four equal portions. Shape each portion into a burger patty, about 1 inch thick. Make a small indentation in the center of each patty with your thumb. This helps the burgers cook evenly and prevents them from puffing up.
Brush the grill grates with olive oil to prevent sticking. Place the patties on the hot grill. Cook for 5-7 minutes on one side without flipping. This ensures a nice golden crust. Flip the patties gently and grill for another 5-7 minutes, or until the internal temperature reaches 165°F.
While the burgers are grilling, mix all the cream cheese sauce ingredients together. Adjust the flavor to your liking with lemon juice, salt, and pepper.
Once the patties are cooked, place them on your choice of buns. Slather on the green onion cream cheese sauce and top with your favorite toppings—tomatoes, lettuce, pickles—whatever floats your boat!
