Instructions

1. Step 1: Place 3 lbs peeled and diced yellow potatoes in a large pot and cover with cold water. Add 1 tsp salt and bring to a boil over high heat. Reduce heat to medium and simmer for 12-15 minutes until potatoes are tender when pierced with a fork. Drain and transfer to a large bowl to cool.
2. Step 2: Meanwhile, place 4 large eggs in a saucepan and cover with water. Bring to a boil, then cover and remove from heat. Let sit for 12 minutes. Cool eggs in ice water, peel, and chop roughly.
3. Step 3: In a small bowl, whisk together 1 cup mayonnaise, 3 tbsp Dijon mustard, 2 tbsp apple cider vinegar, 1/2 tsp salt, and 1/2 tsp black pepper until smooth.
4. Step 4: Add 2 finely chopped celery stalks, 1/2 cup finely chopped red onion, chopped eggs, and 2 tbsp chopped fresh dill to the cooled potatoes. Pour the dressing over the mixture and gently fold to combine without mashing the potatoes.
5. Step 5: Adjust seasoning with 1 tsp salt and 1/2 tsp black pepper if needed. Chill the salad for at least 2 hours. Before serving, sprinkle 1 tsp paprika evenly on top for color and mild smoky flavor.
