Estimated reading time: 6 minutes

There are certain recipes that instantly bring back memories, and this is definitely one of them. Every time I make Gram’s Sweet-Tangy Potato Salad, I’m right back in my grandmother’s kitchen watching her stand at the stove, carefully stirring that homemade dressing that made this recipe so special.

Unlike most potato salads that start with mayonnaise alone, Gram always made her sweet and tangy dressing from scratch. It took a few extra minutes, but it was worth every second. The dressing cooks on the stove until it’s silky smooth before being mixed with mayonnaise, creating the most incredible creamy texture and flavor.

This potato salad showed up at every family picnic, church gathering, holiday cookout, and backyard barbecue. In fact, if Gram walked through the door without it, everyone wanted to know why!

Today, I’m sharing her recipe exactly the way our family has enjoyed it for years. I hope it becomes one of those recipes your family requests over and over again too.

The Secret Is the Homemade Cooked Dressing

If you’ve never made a cooked dressing for potato salad before, don’t let that extra step scare you away. It only takes a few extra minutes, and I promise it’s what makes this recipe so special. Unlike a simple mayonnaise dressing, cooking the eggs, sugar, vinegar, and flour together creates an incredibly smooth, creamy base with the perfect balance of sweetness and tang. Once it’s cooled and mixed with mayonnaise, you end up with a rich, velvety dressing that coats every bite of potato beautifully. It’s the same dressing my grandmother made for every family picnic, and after one bite, you’ll understand why we’ve never made potato salad any other way.

How to Make Gram’s Sweet-Tangy Potato Salad

Step 1

Wash the potatoes and place them into a large stockpot. Cover with water and add about 1 tablespoon of salt.

Bring to a boil and cook until the potatoes are fork tender, about 20 to 25 minutes depending on their size.


Step 2

While the potatoes cook, dice the onion, celery, and hard-boiled eggs.

Set aside.


Step 3

Drain the potatoes and allow them to cool until they’re easy to handle.


Step 4

Meanwhile, make the homemade dressing.

In a medium saucepan, whisk together the sugar and eggs until smooth.

Add the flour, vinegar, and water, then cook over medium heat while stirring constantly.

Continue cooking until the mixture thickens.


Step 5

Remove the saucepan from the heat.

Stir in the butter, salt, and pepper until completely melted.

Allow the dressing to cool.

Once cooled, stir in the mayonnaise until smooth and creamy.


Step 6

Peel the cooled potatoes and cut them into bite-sized pieces.

Place them into a large mixing bowl.

Add the onions, celery, and chopped eggs.


Step 7

Pour the dressing over the potato mixture.

Gently fold everything together until every potato is coated.


Step 8

Cover and refrigerate for at least 4 hours.

For the best flavor, chill overnight before serving.

Yukon Gold, russet, or white potatoes all work well. Yukon Gold potatoes hold their shape better, while russets create a creamier texture.
