Ingredients for potato salad recipe with egg and radishes
Sixteen ingredients for a potato salad that balances creamy, crunchy, and peppery textures perfectly.
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow Potatoes 🥔 | 3 lb | Yukon gold preferred, cut into 1-inch cubes |
| Large Eggs 🥚 | 8 whole | Fresh, for hard-boiling |
| Red Radishes 🍅 | 1 ½ cup | Thinly sliced, fresh for crunch |
| Celery Stalks 🧅 | 4 whole | Diced fine, for crisp texture |
| Mayonnaise 🥫 | 1 ½ cups | High-quality, full-fat preferred |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Dijon Mustard 🍯 | 1 tbsp | For tangy depth |
| Fresh Dill 🌿 | ¼ cup | Chopped finely, for freshness |
| Fresh Chives 🌱 | ¼ cup | Chopped, for mild onion flavor |
| White Vinegar 💧 | 1 tbsp | Balances richness |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The potatoes are the foundation—Yukon golds are ideal for their buttery texture, but Russets work too if that's what you have. Buy them a day ahead so they're fully rested. Fresh eggs make all the difference; skip the pre-peeled cartons—they're often older. Radishes should be firm and crisp; avoid any with soft spots. Celery? The fresher, the better—look for stalks that are crisp and white all the way through. For the dressing, high-quality mayo is non-negotiable—it's the backbone of the creamy texture. Kirkland or Hellmann's are solid choices if you're not making your own.
No radishes? Thinly sliced cucumber or green onions add a similar crunch. Short on dill? Fresh parsley at double the amount works in a pinch, though it lacks that signature tang. The dressing can be made a day ahead—store it in an airtight container in the fridge. If you're avoiding mayo entirely, Greek yogurt at half the amount gives a lighter texture, though it won't be as rich. For the eggs, 10-minute boiling ensures creamy yolks that slice perfectly. If you prefer softer yolks, boil for 8 minutes instead. The vinegar and lemon juice can be swapped for apple cider vinegar if you prefer a fruitier note.
This salad tastes even better the next day as the flavors meld—make it ahead if you're prepping for a picnic or potluck. Store the dressing separately if making ahead to prevent sogginess. Keeps for 3-4 days in the fridge, though the radishes may soften after day two. For a restaurant-quality finish, garnish with extra chives and a sprinkle of freshly cracked black pepper right before serving. The eggs can be peeled and arranged on top for an elegant presentation, or left whole for a rustic touch.

Step-by-step instructions for creamy potato salad with egg and radishes
Here's how to create a perfectly balanced potato salad with tender potatoes, creamy yolks, and crisp vegetables.
Boil the Potatoes Until Fork-Tender
Place the 3 lb yellow potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp kosher salt and bring to a boil over high heat. Once boiling, reduce heat to medium and cook for 12-15 minutes until a knife slides in easily with slight resistance.
The potatoes should be tender but not falling apart—this ensures they hold their shape when mixed with the dressing. I like to test one potato first by piercing it with a knife. If it feels slightly firm in the center but yields easily, they're ready. Drain immediately and let them cool for 5 minutes before handling further.
Hard-Boil the Eggs for Creamy Yolks
Place the 8 whole large eggs in a saucepan and cover with cold water by about 1 inch. Bring to a boil over high heat, then remove from heat, cover, and let sit for exactly 10 minutes. This timing gives you perfectly set whites with creamy, rich yolks that won't break apart when sliced.
Transfer the eggs to an ice bath for 10 minutes to stop the cooking process completely. This cooling step prevents overcooked yolks that can turn greenish around the edges. Once cooled, peel the eggs under running water to remove any remaining shell fragments. Slice each egg into 6 wedges and set aside until ready to mix into the salad.
Prepare the Creamy Dressing Base
In a large mixing bowl, combine the 1.5 cups mayonnaise, 0.5 cup sour cream, 1 tbsp Dijon mustard, 1 tbsp white vinegar, and 1 tbsp lemon juice. Whisk vigorously until fully incorporated and smooth. This combination creates the perfect balance of richness and tang that prevents the salad from becoming too heavy.
Add the 0.25 cup chopped fresh dill and 0.25 cup chopped fresh chives, mixing gently to distribute the herbs evenly. The fresh dill adds bright herbal notes while the chives contribute a subtle onion flavor that complements the radishes. Taste the dressing and adjust seasoning with additional salt or pepper if needed—this is your flavor foundation.
Mix All Ingredients for Perfect Texture
Add the cooled potatoes to the dressing mixture and gently fold with a rubber spatula until fully coated. The potatoes should absorb the dressing completely but still maintain their shape. Work quickly to prevent the potatoes from breaking apart, which can make the salad mushy.
Fold in the sliced eggs, 1.5 cup thinly sliced red radishes, and 4 whole celery stalks diced fine. The radishes add a crisp peppery bite while the celery contributes a refreshing crunch. Gently mix just until combined—overmixing can break down the potatoes and release excess starch, making the salad gummy.
Chill and Serve for Optimal Flavor
Cover the salad bowl and refrigerate for at least 2 hours, or preferably overnight. This chilling time allows all the flavors to meld together perfectly and gives the dressing time to fully coat each ingredient. The potatoes will absorb the dressing more completely, resulting in a creamy texture throughout.
Before serving, give the salad one final gentle toss to redistribute any settled ingredients. The salad should be creamy from the dressing and yolks, with crisp radishes and celery providing textural contrast. Serve chilled with crusty bread or alongside grilled meats for a complete meal.
Pro Tips For Making Potato Salad Recipe With Egg And Radishes
- Boil Potatoes Until Fork-Tender: Drain them just before they’re fully done—yellow potatoes should yield to a fork but still hold shape. Overcooking turns them into mush, and nobody wants that sad, gluey texture. Test one early, or they’ll fall apart when you slice.
- Slice Radishes Paper-Thin: Use a sharp knife and cut them almost translucent—think 1/16-inch slices, not the 1/4-inch chunks you’d use for a quick snack. Thin slices keep the crunch and let the flavor shine without overwhelming the dish.
- Chill Eggs Before Chopping: Pop the hard-boiled eggs straight from the ice bath into the fridge for 10 minutes first. Cold eggs slice cleanly and won’t turn your salad into a watery mess. Warm eggs? Disaster. Trust me.
- Mix Dressing Last, Gently: Toss the potatoes with radishes, celery, and eggs first, then fold in the mayo just before serving. This keeps the radishes from bleeding color and the celery from turning limp. Stir like you’re folding in a delicate omelet—no brute force.
Flavor customization for this potato salad recipe with egg and radishes
Classic vs. Tangy Dressing
For a classic mayo-based dressing, stick to the original recipe with its creamy richness. But if you prefer something lighter, swap ½ cup of the mayo for ½ cup Greek yogurt—this keeps the creaminess while cutting calories.
For a tangy twist, add 1 extra tbsp of Dijon mustard and ½ tsp of smoked paprika to the dressing for depth. 💫
Herb Variations
Swap out the dill and chives for other herbs based on what you have. Fresh parsley (double the amount) works in a pinch, but for bold flavor, try snipped chives + tarragon or dill + a pinch of dried dill weed.
For a Southern touch, add 1 tbsp finely chopped fresh thyme to the dressing—it pairs beautifully with radishes.
Spicy Kick Options
Add heat with ½ tsp of cayenne pepper or 1 tsp of hot sauce (like Crystal or Tabasco) to the dressing. For a smoky-spicy twist, mix in ½ tsp of smoked salt with the black pepper.
If you love radishes, their natural peppery bite pairs perfectly with mild heat—just don’t overdo it or the salad will lose its balance.
Veggie Swaps
No radishes? Try thinly sliced cucumber or green onions for crunch. For a sweeter contrast, add ½ cup diced bell pepper or ¼ cup finely chopped red onion.
If you want extra texture, toss in ¼ cup toasted sunflower seeds or crumbled bacon for a smoky depth. Just keep portions balanced to avoid overpowering the potatoes.
Dairy-Free Adaptations
For a vegan version, replace the mayo with ½ cup vegan mayo and the sour cream with ½ cup silken tofu blended until smooth. To maintain creaminess, add 1 tbsp of nutritional yeast for a cheesy note.
The eggs can be omitted entirely, or use silken tofu cubes marinated in soy sauce for a protein boost. The radishes and celery will still provide that essential crunch! 🥗

Frequently asked questions
Can I use waxy potatoes instead of Yukon Gold?
Yes, but with a few adjustments! Red potatoes or fingerlings work well—their firmer texture holds up better when sliced thin. Boil them 2-3 minutes less than Yukon Golds (about 10-12 minutes) to prevent mushiness. For extra creaminess, add 1 tbsp of extra sour cream to the dressing to compensate for their drier starch.
How do I prevent the radishes from getting soggy?
Add the radishes and celery just before serving to preserve their crunch. For extra protection, toss them with ½ tsp of lemon juice before mixing into the salad. If making ahead, store the veggies separately in the fridge and fold them in right before serving—this keeps their texture crisp for up to 24 hours.
Can I make this potato salad ahead of time?
This salad tastes even better after 4-6 hours in the fridge as flavors meld. For best results, prepare the dressing and boil the potatoes the night before, then combine everything 2 hours before serving. Store the eggs separately if making more than 1 day ahead to prevent them from absorbing too much moisture.
What's the secret to creamy egg yolks?
The 10-minute ice bath after boiling is key! This stops the cooking process completely, preventing greenish yolks. For extra-rich yolks, use fresh, room-temperature eggs (they peel easier too). If you prefer softer yolks, slice the eggs and fold them in just before serving so they stay creamy.
Can I make this without mayo?
Yes! Replace the mayo with 1 cup Greek yogurt + ½ cup sour cream for a lighter texture. For richness, add 1 tbsp of Dijon mustard + 1 tbsp of lemon juice to balance the tang. The salad will be slightly lighter but still creamy—just fold in the veggies right before serving to maintain crunch.
