Method
7 steps- 1
Heat 1 tablespoon vegetable oil in a large nonstick skillet over medium heat. Add sliced onion and cook, stirring occasionally, until softened and browned, about 15 minutes. Transfer to a bowl and wipe out skillet.

Heat another tablespoon vegetable oil over medium heat. Add celery and apple and cook until softened, about 4-6 minutes. Transfer to bowl with onion. Add ground turkey, parsley, salt, and black pepper. Mix well.

Using hands, shape mixture into four 1/2-inch thick patties.

Add remaining tablespoon vegetable oil to skillet and heat over medium-high heat. Add burgers and cook for 5 minutes, flip, and cook 5 minutes more until no longer pink inside.
- 5
While burgers cook, whisk together mustard, mayonnaise, lemon zest, lemon juice, and cayenne pepper in a small bowl. Set aside.
- 6
Transfer cooked burgers to a plate. Brush plain mayonnaise on cut sides of buns and place face down on skillet for about 2 minutes until lightly toasted.

Spread lemon aioli mixture on top bun halves. Place turkey patties on bottom halves. Top with caramelized onions and close burgers.
Tips
Caramelize onions fully (15 minutes) for deep sweetness that balances the lean turkey.
Keep celery and apple pieces small and cook until softened to distribute evenly through patties.
Handle turkey mixture gently to avoid dense burgers; shape patties to consistent thickness for even cooking.
Toast buns cut-side down in residual skillet heat to add textural contrast without soaking up excess moisture.
Good to Know
Cooked burgers keep refrigerated up to 3 days; reheat gently in skillet over medium heat. Patties can be formed and frozen on a tray, then transferred to freezer bags up to 1 month; cook from frozen, adding 2-3 minutes per side.
Form patties up to 8 hours ahead, cover, and refrigerate. Prepare lemon aioli and caramelized onions up to 1 day ahead.
Serve immediately while buns are warm and burgers are hot. Accompany with pickled vegetables, lettuce, or tomato slices on the side.
Common Mistakes
Do not skip caramelizing onions fully to avoid underseasoned, flat-flavored burgers.
Do not overwork turkey mixture when shaping to avoid dense, tough patties.
Do not cook patties beyond 10 minutes total to avoid dry meat; turkey requires careful heat management.
Do not use cold buns that haven't been toasted to avoid soggy bread from condiments.
