Method
Cook and cool the potatoes
- Bring a Dutch oven of water to a boil, then add the cubed red potatoes and cook until tender, 10 to 15 minutes. You should be able to pierce a potato cube easily with a fork.
- Drain the potatoes and spread them on a sheet pan to cool until no longer steaming. Letting them cool helps the dressing cling without turning runny.
Make the lemon dill dressing
- In a bowl, whisk together mayonnaise, sour cream, fresh lemon juice, lemon zest, fresh dill, and Dijon mustard until smooth and creamy. The mixture should look evenly speckled with dill and zest.
Assemble and season
- Combine the cooled potatoes and finely diced red onion in a bowl. Gently distribute the onion so each bite gets a little color.
- Pour the dressing over the potatoes and toss gently until everything is coated. Lift and fold rather than stirring hard to keep cubes intact.
- Season with salt and black pepper to taste. Add gradually and taste to balance the lemon.
Chill
- Cover and refrigerate the potato salad for at least 2 hours. Chilling firms the texture and improves flavor blend.
Notes
Pro tip: cool the potatoes fully before dressing so they don’t absorb too much lemon and become gummy. Store in the refrigerator up to 4 days; freeze is not recommended because potatoes and dairy dressing can break. For a lighter option, use light mayonnaise or a Greek-yogurt blend in place of part of the mayonnaise and keep the sour cream reduced accordingly.
