Salads
A potato salad recipe with egg and radishes that delivers crisp radishes and fluffy eggs in every bite is the perfect balance of traditional comfort and fresh, bright flavors.
This isn’t your grandmother’s mayo-heavy version—it’s a lighter take with a tangy vinegar dressing that keeps the potatoes tender and the radishes delightfully crisp. I developed this after years of experimenting with my grandmother’s handwritten notes, finally nailing the texture contrast that makes it irresistible.
The secret lies in the technique: boiling potatoes until they’re fork-tender but still hold their shape, hard-boiling eggs just until the yolks are creamy, and slicing radishes thin enough to add crunch without overwhelming the dish.
A classic vinegar-based dressing with Dijon mustard and fresh herbs ties everything together, creating a salad that’s creamy yet light, fresh yet satisfying. It’s the kind of dish that feels special enough for a picnic but simple enough for a weeknight dinner.
What you’ll end up with is a potato salad that’s creamy from the eggs, bright from the radishes, and perfectly seasoned—each bite offering a mix of textures and flavors that keep you reaching for more.
The dressing clings to the potatoes without making them soggy, and the radishes stay crisp even after sitting for a few hours. This is the potato salad I wish I’d had growing up: balanced, flavorful, and impossible to resist.
Serve it at summer gatherings, pack it in lunches, or enjoy it as a side for grilled meats. The recipe scales easily, so you can make it for a crowd or just a family of four.
Here’s how to bring it to life—step by step, with all the tips and tricks I’ve learned along the way.
Ingredients for potato salad recipe with egg and radishes
Fresh potatoes, creamy eggs, and crisp radishes—this salad balances textures perfectly.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Potatoes 🥔 | 2 ½ lb | Yukon gold preferred, cut into 1-inch cubes |
| Large Eggs 🥚 | 6 whole | Hard-boiled, peeled, halved lengthwise |
| Red Radishes 🧅 | 1 ½ lb | Thinly sliced, soak in cold water 10 mins |
| Red Wine Vinegar 🍷 | ½ cup | Dry variety for tangy flavor |
| Extra-Virgin Olive Oil 🫒 | ½ cup | Light, fruity variety preferred |

| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Chives 🌱 | ¼ cup | Thinly sliced, for garnish |
| Granulated Sugar 🍚 | 1 tbsp | Balances vinegar acidity |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |

The potatoes are the foundation, so Yukon golds are ideal—they stay creamy but hold shape better than russets. Trader Joe's and Whole Foods usually carry them pre-washed, which saves time. If you can't find Yukon golds, red potatoes work too, but they'll be slightly firmer. The radishes? Look for vibrant, firm ones—avoid any with soft spots or wilted tops. I like to slice them paper-thin so they stay crisp even after sitting for a few hours. The eggs should be fresh—older eggs are harder to peel and don't hold their shape as well when halved.
No fresh dill? Dried dill at one-third the amount works in a pinch, but fresh is worth the extra minute. Short on mayo? Greek yogurt thinned with olive oil gives a similar creaminess without overpowering. The red wine vinegar can be swapped for apple cider vinegar, but dry red wine vinegar has the best depth. If you're making this ahead, add the radishes and eggs just before serving to keep them crisp. The dressing can be made a day in advance—it actually tastes better after the flavors meld for a bit. For extra crunch, add a handful of toasted sunflower seeds at the end.
Store the dressing separately in the fridge for up to 5 days—it keeps beautifully. The potatoes and veggies hold up well for 3 days if stored in airtight containers. The eggs? Peel and store them in the fridge for 2 days max—they'll stay fluffy but can get rubbery if left too long. This salad is perfect for meal prep: assemble everything the night before and toss with dressing in the morning. The radishes will stay crisp if you keep them submerged in cold water until you're ready to add them.

Step-by-step instructions for potato salad with egg and radishes
Here's how to create a vibrant, flavorful potato salad with crisp radishes and fluffy eggs.
Prepare the Potatoes for Perfect Texture
Place the 2.5 lb yellow potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp salt and bring to a boil over high heat. Once boiling, reduce heat to medium and cook for 15-18 minutes until potatoes are tender when pierced with a fork but still hold their shape.
Drain immediately and transfer to a large bowl. Let them steam-dry for 2 minutes—this helps remove excess moisture that would make your salad soggy. While still warm, gently toss the potatoes with 2 tbsp Dijon mustard and 1 tbsp granulated sugar. The sugar will caramelize slightly as it cools, adding depth of flavor.
Hard-Boil the Eggs for Fluffy Centers
Place the 6 whole large eggs in a saucepan and cover with cold water by about 1 inch. Bring to a boil over high heat, then immediately remove from heat, cover, and let sit for 12 minutes. This timing ensures perfectly set whites with creamy yolks.
Transfer eggs to an ice bath for 5 minutes to stop cooking. Peel under cool running water and halve lengthwise. Arrange the egg halves on top of the warm potatoes—their warmth will help them stay creamy as the salad cools.
Create the Tangy Dressing
In a medium bowl, whisk together the 0.5 cup extra-virgin olive oil, 0.5 cup red wine vinegar, 0.25 cup mayonnaise, 0.25 cup chopped fresh dill, and 0.5 tsp black pepper. The vinegar will initially separate, but keep whisking until it emulsifies into a smooth dressing. This balance of acidity and creaminess is what makes this salad truly special.
Taste and adjust seasoning—you might want to add a pinch more salt or sugar depending on your vinegar's acidity. The dressing should coat the back of a spoon but still allow for easy mixing.
Assemble with Crunchy Vegetables
Drain the 1.5 lb thinly sliced red radishes and pat completely dry with paper towels. Toss them with 0.25 cup thinly sliced red onion and 1 whole diced celery stalk. Add these to the potato-egg mixture along with the dressing and gently fold everything together.
Here's the thing—don't overmix. You want the potatoes to stay slightly separated so each bite has that perfect combination of creamy potato, fluffy egg, and crisp radish. Let the salad sit at room temperature for 15 minutes before serving to allow flavors to meld.
Garnish and Serve with Fresh Herbs
Just before serving, sprinkle the salad with 0.25 cup thinly sliced fresh chives and an additional 1 tbsp chopped fresh dill. The bright green color and fresh flavor will make your salad look as good as it tastes.
Serve immediately while the radishes are still crisp and the eggs maintain their creamy texture. This salad keeps well in the refrigerator for up to 2 days, but I promise you'll want to eat it all in one sitting!
Pro Tips For Making Potato Salad Recipe With Egg And Radishes
- Boil Potatoes Until Fork-Tender: Yellow potatoes need to be cooked just past done—cut them when still slightly firm, then boil 12-15 minutes until a knife slides in like butter. Overcooking turns them gluey, and undercooking means a sad, chewy bite. Test one early; you’ll thank yourself later.
- Peel Radishes Thin, Keep Them Whole: Skip the mandoline—peel radishes with a paring knife, leaving the skin on the flat side for grip, then slice them into ¼-inch thick rounds. Whole radishes bleed less and stay crisp longer in the dressing. I used to dice them, but this keeps the texture bright and sharp.
- Shock Eggs Immediately After Boiling: As soon as the timer goes off, plunge eggs into ice water for 5 minutes. This stops the cooking process and makes peeling them effortless. I learned this the hard way—eggs left to cool in the pot stick like glue, and no one wants to fight their salad before serving.
- Dress Potatoes Warm, Not Hot: Toss the warm potatoes with dressing while still at 130°F (55°C)—just out of the pot, not scalding. This lets the oil and vinegar cling instead of pooling at the bottom. I used to wait until fully cooled, and the salad always ended up dry and oily. Warm works better.
Best sauces and condiments for potato salad recipe with egg and radishes
Classic Vinegar Dressing
The heart of this potato salad is the tangy vinegar dressing, which balances the creamy potatoes and eggs perfectly. I use ½ cup red wine vinegar for its depth—it’s more complex than white vinegar and adds a subtle fruitiness.
Whisk it with ½ cup extra-virgin olive oil and 2 tbsp Dijon mustard until emulsified. The mustard adds a touch of sharpness that cuts through the richness, while the olive oil keeps everything silky.
Pro tip: If your vinegar is particularly strong, add 1 tbsp granulated sugar to balance the acidity. This dressing is what transforms a simple potato salad into something truly special. 🍷
Creamy Mayo Twist
For a creamier texture without sacrificing freshness, I fold in ¼ cup light mayonnaise into the dressing. It adds a luxurious mouthfeel while keeping the salad light enough to enjoy in summer.
If you’re watching calories, swap the mayo for Greek yogurt thinned with 1 tbsp olive oil—it gives a similar tangy creaminess. The key is to add the mayo after emulsifying the vinegar and oil, so it blends seamlessly.
Trust me, this small addition makes all the difference in keeping the salad cohesive and flavorful. 🥫
Herb-Infused Freshness
Fresh herbs elevate this salad from ordinary to extraordinary. I chop ¼ cup fresh dill and ¼ cup chives—the dill adds a bright, slightly citrusy note, while the chives lend a delicate onion flavor.
For extra depth, I sometimes add 1 tsp finely chopped tarragon or thyme, but stick to dill and chives for a classic approach. The herbs should be added last to preserve their vibrant color and fresh aroma.
A sprinkle of chopped herbs on top right before serving adds a pop of color and a burst of flavor with every bite. 🌿
Spicy Kick Option
If you love a little heat, add ½ tsp smoked paprika or ¼ tsp cayenne pepper to the dressing for a subtle smoky or fiery twist. I also like to include 1 tbsp finely chopped jalapeño (seeds removed) for a fresh, bright heat that pairs beautifully with the creamy potatoes.
For a sweeter-spicy balance, drizzle with 1 tsp honey after assembling. This works especially well if you’re serving the salad at a picnic or BBQ, where bold flavors shine. 🌶️
Sweet and Tangy Balance
To round out the flavors, I always include 1 tbsp granulated sugar in the dressing—it’s a trick I learned from my grandmother to soften the vinegar’s sharpness. If you’re using a particularly tart vinegar, you might need 1½ tbsp sugar.
For a more complex sweetness, swap the sugar for 1 tsp honey or maple syrup. This balance is what makes the salad taste finished—not too sharp, not too bland, but perfectly harmonized. 🍯

Frequently asked questions
Why do you soak the radishes before adding them?
Soaking the thinly sliced radishes in cold water for 10 minutes removes excess bitterness and keeps them crisp longer. The water also helps clean off any dirt or sand from the skins. Pat them completely dry before adding to the salad to prevent sogginess—this is the secret to maintaining that perfect crunch!
Can I make this potato salad ahead of time?
Store the dressing separately in the fridge for up to 5 days, and the potatoes/veggies for 3 days. Keep the eggs peeled and refrigerated for just 2 days max—they stay fluffy but can get rubbery if stored longer. Add radishes and eggs just before serving to preserve their texture.
What's the best way to keep the eggs creamy?
Hard-boil eggs for exactly 12 minutes (not longer!) and transfer them immediately to an ice bath. Peel under cool running water to prevent overcooking. Place the halved eggs on warm potatoes—their residual heat helps maintain that perfect creamy yolk texture when everything comes together.
Can I substitute mustard in the dressing?
Yes! For a milder flavor, use 2 tbsp whole-grain mustard or swap for 1 tbsp lemon juice to brighten the dressing. If you love tang, try 1 tbsp apple cider vinegar instead of red wine vinegar—both work beautifully. The key is maintaining that vinegar-oil balance for the perfect emulsification.
How do I fix soggy radishes in my potato salad?
If radishes lose their crunch, drain them immediately and pat extra dry with paper towels. For extra insurance, toss them with ½ tsp cornstarch before adding to the salad—this helps absorb moisture. Always add radishes last and serve promptly for maximum crispness.
