01 - Preheat oven to 425°F. Toss sweet potato fries with olive oil, sea salt, smoked paprika, and black pepper. Spread evenly on a parchment-lined baking sheet.
02 - Bake fries for 30 to 35 minutes, turning halfway through, until edges are golden and crispy.
03 - Combine ground turkey, chopped onion, minced garlic, parsley, Dijon mustard, Worcestershire sauce, smoked paprika, salt, and pepper in a large bowl. Mix gently until just combined.
04 - Shape mixture into four equal patties. Heat olive oil in a non-stick skillet over medium heat. Cook patties 5 to 6 minutes per side until browned and fully cooked with an internal temperature of 165°F. Optionally add cheese slices during the last minute of cooking.
05 - Lightly toast burger buns.
06 - Place a lettuce leaf on the bottom bun, add turkey patty, then top with tomato, red onion, pickles, and preferred sauces.
07 - Serve burgers immediately with sweet potato fries on the side.
