Prepare the Ingredients
Boil the chicken breast, potatoes, carrot, and eggs until fully cooked. Let them cool before peeling and grating.
Thinly slice the onion and finely chop the pickles.
Assemble the Layers
In a serving dish, start with a layer of grated potatoes. Season lightly with salt and pepper.
Add the shredded chicken on top, followed by a thin layer of mayonnaise.
Spread the sliced onions evenly, then add a layer of grated carrots.
Sprinkle the chopped pickles over the top, followed by the grated eggs.
In a small bowl, mix sour cream, mustard, and the remaining mayonnaise, then spread it over the salad as the final layer.
Chill and Serve
Refrigerate for at least 30 minutes to allow the flavors to blend.
Garnish with fresh dill before serving.
