Step‑by‑Step Instructions for Sour Cream and Onion Potato Salad
Step 1: Prep Potatoes
Begin by washing and peeling about 2 pounds of Yukon Gold potatoes. Cut them into bite-sized chunks, then place them into a large pot. Add enough water to cover the potatoes and a generous pinch of kosher salt. Bring to a boil over high heat, then reduce to a simmer, cooking for 10–15 minutes, or until the potatoes are fork-tender. Drain and set aside to cool slightly.
Step 2: Season Warm Potatoes
Drizzle the still-warm potatoes with 2 tablespoons of white vinegar, ensuring each piece is lightly coated. Sprinkle a pinch of kosher salt over them for enhanced flavor. Let the potatoes absorb the vinegar and cool completely at room temperature, allowing the tangy flavor to blend in before adding everything else to your Sour Cream and Onion Potato Salad.
Step 3: Make Dressing
In a medium mixing bowl, combine 1 cup of full-fat sour cream, ½ cup of mayonnaise, and ¼ cup of buttermilk. Add 1 tablespoon of Dijon mustard, 1 teaspoon of onion powder, 1 teaspoon of garlic powder, and a sprinkle of freshly ground black pepper to taste. Whisk until the mixture is smooth and creamy. This dressing is the backbone of your Sour Cream and Onion Potato Salad, providing all its delightful tang.
Step 4: Combine Ingredients
To the dressing, add ½ cup of diced green onions, ¼ cup of finely chopped red onion, and ¼ cup of chopped celery for extra crunch. For additional flavor, fold in a handful of fresh herbs like chopped chives and parsley. If desired, mix in 1 cup of shredded sharp cheddar cheese and crumbled bacon. Stir well to incorporate all the ingredients, creating a flavorful base for the salad.
Step 5: Fold in Potatoes
Carefully transfer the cooled potatoes into the dressing mixture. Gently fold the potatoes using a spatula, ensuring that they are well-coated with the creamy dressing without mashing them. The goal is to maintain the lovely texture of the Yukon Gold potatoes while creating the perfect Sour Cream and Onion Potato Salad.
Step 6: Chill
Cover the bowl with plastic wrap or transfer the salad to an airtight container. Refrigerate the Sour Cream and Onion Potato Salad for at least 30 minutes or, for best results, overnight. This chilling step allows the flavors to meld beautifully, resulting in a refreshing and delicious salad that is ready for your next gathering.
Step 7: Serve
Just before serving, taste the potato salad and adjust seasoning as needed. For an added crunch, top the salad with 1 cup of crushed sour cream and onion potato chips. This last-minute addition will provide a delightful texture contrast and enhance the overall flavor of your salad. Serve chilled, and enjoy the rave reviews!

How to Store and Freeze Sour Cream and Onion Potato Salad
Fridge: Store in an airtight container for up to 3-4 days. If the salad thickens, just stir in a splash of milk or buttermilk before serving.
Freezer: For best results, avoid freezing as the potatoes may become mushy. If necessary, store in a freezer-safe container for up to 1 month, but expect a change in texture.
Thawing: If frozen, thaw overnight in the fridge before serving. Re-mix gently to restore creaminess, adding more dressing if needed.
