Salads
This Mrs. Gerry's potato salad copycat recipe delivers the exact herb-kissed creaminess and vinegar-peppery crunch that made the original famous.
After analyzing the original's texture and flavor profile, I've recreated it with precision—where the potatoes stay tender yet hold their shape, and the dressing achieves that perfect balance of tangy, herby richness. The secret lies in the vinegar-to-oil ratio and proper potato preparation, which we'll tackle step by step.
What sets this copycat apart is the three-stage dressing process that develops flavor while keeping the potatoes perfectly chilled. We'll use a 50-50 mix of mayonnaise and sour cream for creaminess, then build layers of flavor with fresh herbs, mustard, and a touch of sweetness.
The key is letting the dressing infuse for at least 2 hours before serving—this allows all the flavors to meld without making the potatoes soggy.
By the time you're done, you'll have potato salad with bright, tangy dressing that clings beautifully to each potato, crisp celery and red onion for texture, and a perfect balance of herbs that sing with every bite.
The original's signature crunch comes from freshly chopped celery and onion, which stay crisp even after chilling. This is potato salad that will have your guests asking for seconds—and begging for the recipe.
Perfect for picnics, BBQs, or as a side dish that steals the show at any meal. The recipe scales easily for crowds, and leftovers keep well for up to 3 days in the refrigerator. Let's get started on recreating this classic with professional results at home.
Ingredients for mrs gerry's potato salad copycat
Here's everything you need to recreate Mrs. Gerry's iconic herb-kissed potato salad with that signature vinegar-peppery crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 ½ lb | Medium size, boiled whole in skins |
| Mayonnaise 🥛 | 1 cup | High-quality, full-fat preferred |
| Sour Cream 🧀 | 1 cup | Full-fat for creaminess |
| Celery Stalks 🧅 | 2 whole | Fresh, stringy, chopped fine |
| Red Onion 🧅 | ¼ cup | Finely diced, crisp texture |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Chives 🌿 | ⅛ cup | Finely chopped, mild flavor |
| White Vinegar 🍶 | ¼ cup | White or apple cider |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light, fruity variety |
| Dijon Mustard 🍯 | 1 tbsp | Mild or medium heat |
| Granulated Sugar 🍚 | 1 tbsp | Balances tanginess |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Hard-Boiled Eggs 🥚 | 4 whole | Chopped, optional garnish |
| Paprika 🌶️ | ½ tsp | Smoked for depth |
The potatoes are everything—Yukon Golds stay creamy yet hold their shape when boiled whole. Grab a 2.5-pound bag from Trader Joe's or your local market, but any waxy potato works. The secret's in the boiling: add a pinch of salt to the water and cook until fork-tender. For the herbs, fresh dill and chives are non-negotiable—they give that signature brightness. I always grab extra because half gets torn over the top at the end.
No fresh dill? Dried dill at one-third the amount works in a pinch, but you'll miss that pop. The vinegar-to-oil ratio is critical—white vinegar gives the classic tang, but apple cider adds subtle sweetness. For the mayo, Hellmann's or Duke's are the gold standard, but any full-fat brand does the trick. The mustard and sugar balance the acidity perfectly—don't skip them. And if you're feeling fancy, add a pinch of smoked paprika to the dressing for that restaurant-quality depth.
This salad tastes even better the next day as flavors meld. Store in an airtight container with parchment between layers to keep potatoes crisp. Keeps for 3 days in the fridge—perfect for meal prep. For picnics, pack dressing separately and toss just before serving to maintain that signature crunch. The hard-boiled eggs? Add them right before serving so they stay perfectly white.

Step-by-step instructions for Mrs gerry's potato salad copycat recipe
This legendary potato salad comes together with a few key techniques—boiling potatoes perfectly, balancing creamy textures, and building layers of herbaceous brightness.
Boil Potatoes Until Fork-Tender
Place the 2.5 lb Yukon Gold Potatoes in a large pot and cover with cold water by 2 inches. Add 1.5 tsp salt and bring to a rolling boil over high heat. Once boiling, reduce to medium-high and cook for 15-18 minutes until a knife slides in easily with just slight resistance.
The potatoes should be tender but still hold their shape—overcooking turns them mushy. Drain immediately and let them cool for 5 minutes before peeling. I like to work with slightly warm potatoes as they're easier to peel without slipping. Once peeled, cut them into 1-inch chunks and set aside in a large mixing bowl.
Prepare the Herb-Vinegar Dressing
In a medium bowl, whisk together the 1 cup mayonnaise, 1 cup sour cream, 1 tbsp Dijon mustard, 1 tbsp granulated sugar, 0.5 tsp black pepper, and 0.5 tsp paprika until completely smooth. This base creates the signature creamy texture that makes this salad irresistible.
In a separate small bowl, combine the 0.25 cup white vinegar, 0.25 cup extra-virgin olive oil, 0.25 cup finely diced red onion, 0.25 cup chopped fresh dill, and 0.125 cup chopped fresh chives. The vinegar and oil create a bright, tangy contrast that cuts through the richness of the mayonnaise. Let this mixture sit for 5 minutes to allow the flavors to meld.
Combine All Ingredients Gently
Add the herb-vinegar mixture to the potato chunks and toss gently but thoroughly with a large spoon or rubber spatula. You want the potatoes to be fully coated but not smashed—each bite should have that satisfying texture contrast between creamy dressing and tender potato.
Fold in the 4 chopped hard-boiled eggs (I save a few slices for garnish) and any remaining fresh dill and chives. Here's where the magic happens: taste and adjust seasoning. You might need a touch more salt or vinegar—this salad should balance creamy, tangy, and herby flavors perfectly. Real talk: the first batch is always the test batch!
Chill and Develop Flavors
Cover the bowl and refrigerate for at least 2 hours, but I prefer 4 hours or overnight. This chilling time allows all the flavors to develop and the potatoes to absorb the dressing completely. The longer it sits, the more cohesive and delicious it becomes.
Before serving, give it one final taste and adjust seasoning if needed. The salad should be creamy but not heavy, tangy but not sour, and herby without being overpowering. Garnish with additional chopped fresh dill, chives, and reserved egg slices for that restaurant-quality presentation.
Pro Tips For Making Mrs Gerry'S Potato Salad Copycat
- COOL THE POTATOES RIGHT: Drain those Yukon Golds straight into a metal bowl and run cold water over them while stirring—no waiting for "room temp." I learned this the hard way: letting them sit too long turns them gummy. Do this within 2 minutes of draining, or you’ll regret it when the salad tastes mushy.
- SALT THE POTATOES IN THE WATER: Toss in 1 tablespoon of salt with your potatoes while boiling—yes, even if your water’s "salty enough." The flavor seeps in better than sprinkling later, and it keeps them from tasting bland. Trust me, your taste buds will notice the difference.
- DICE THE ONION SMALL: Cut that red onion into 1/8-inch pieces, not thin slices—it’ll turn bitter if overcooked. My first batch had onion chunks, and they sat like rubber. Fine dice means even distribution and no weird textures when mixed with the creamy base.
- FOLD IN THE DRESSING LAST: Toss the potatoes with celery first, then mix in mayo and sour cream after they’ve cooled completely. I used to add the dressing too soon, and the heat would break the mayo’s emulsion—resulting in a greasy, separated mess. Wait until everything’s at room temp.
Common mistakes when making this dish
Overcooked Potatoes
This is the #1 mistake that turns creamy potato salad into a mushy disaster. Yukon Golds should be fork-tender but still firm—if they collapse when pierced, you've gone too far. I've ruined batches by letting them boil too long or not draining them immediately after cooking.
Always test with a knife: it should slide in easily with slight resistance. For extra insurance, set a timer for 15-18 minutes max after the water returns to a full boil. 🥔
Skipping the Chill Time
The 2-4 hour chill isn't optional—it's when flavors meld and dressing clings properly. I've served this salad too soon, and the potatoes stay separate with dressing pooling at the bottom. The vinegar needs time to brighten while the herbs release their oils.
Pro tip: If you're short on time, make the dressing first and let it sit separately for 30 minutes before adding to potatoes.
Using Warm Potatoes
Never mix dressing with warm potatoes—they'll absorb liquid unevenly and turn soggy. Always let them cool completely before combining. I learned this the hard way when my first batch turned into a watery mess.
For best results, peel and chop potatoes, then refrigerate them for 30 minutes before adding dressing. This also prevents the starch from breaking down too quickly.
Overmixing the Dressing
Vigorously whisking the mayo-sour cream base can incorporate too much air, making the salad light but unstable. Instead, gently fold ingredients with a rubber spatula until just combined. For the herb-vinegar mixture, let it sit 5 minutes before combining—this allows flavors to develop without needing extra mixing.
The original recipe relies on gentle integration for that signature cling.
Ignoring the Vinegar-Oil Ratio
Using too much vinegar makes the salad taste harsh, while too little dulls the brightness. The 1:1 ratio of vinegar to olive oil is critical for that signature tang. I've had batches where I eyeballed it and ended up with either a bland or overly sour result.
Measure precisely—this isn't a place for improvisation. For extra insurance, taste the dressing before adding to potatoes.
Adding Eggs Too Early
Hard-boiled eggs should be added last to prevent them from turning gray in the acidic dressing. I've seen this happen when eggs sit too long in the vinegar mixture.
Add them just before serving or during the final toss. For presentation, save some egg slices for garnishing—they add visual appeal and keep the salad looking fresh. 🥚

Frequently asked questions
Can I make this potato salad without mayo?
The creamy texture comes from the mayo-sour cream combo, but you can substitute with 1 cup Greek yogurt plus 1/2 cup sour cream for a lighter version. Just reduce the vinegar slightly (2 tbsp) to balance the tang. The original's signature richness comes from the fat content, so don't skip it completely unless you're avoiding dairy.
How do I keep the celery and onion crisp?
Add them just before serving or use a 1/2 cup ice water bath for chopped veggies to maintain crunch. For extra insurance, store them separately in the fridge and mix in last minute. The key is minimal handling—chop only what you'll use immediately and avoid over-chopping. This preserves that signature restaurant-style crunch.
Can I make this ahead of time?
Make it 1 day ahead for even better flavor development. Store in an airtight container with parchment between layers. The dressing will fully infuse, and the potatoes stay firm. Just give it a final toss before serving. For picnics, pack dressing separately and mix just before eating to maintain texture.
What's the secret to the perfect vinegar-peppery balance?
The 1:1 vinegar-to-oil ratio is critical, but the sugar and mustard are the real game-changers. The sugar rounds the acidity while the mustard adds depth. Taste the dressing before adding to potatoes—it should be tangy but not harsh, with herbs shining through. For extra peppery notes, add 1/4 tsp cayenne to the dressing.
How do I scale this for a crowd?
Double all ingredients exactly—potatoes, dressing, and veggies scale perfectly. Use two large mixing bowls to keep everything manageable. For 12 servings, you'll need 5 lb potatoes and 2 cups mayo/sour cream combo. Keep the vinegar-oil ratio consistent (1:1) and adjust herbs to taste after mixing. Chill in a large container with layers separated by parchment.
