Mrs Gerry's Potato Salad Copycat Recipe: Buttery Mayonnaise and Herb-Packed Perfection

This Mrs Gerry's potato salad copycat recipe delivers the same creamy, herb-packed perfection that made the original legendary. The secret lies in a precise balance of buttery mayonnaise, tangy vinegar, and fresh herbs that transform simple potatoes into a crowd-pleasing masterpiece.

I've perfected this version through careful testing to ensure the texture matches the original—fluffy yet firm, with just the right amount of moisture.

The foundation of great potato salad begins with the potatoes themselves—waxy varieties like red or Yukon Gold hold their shape while absorbing flavor beautifully. After boiling them just until tender, we let them cool completely before mixing to prevent a gummy texture.

The dressing combines mayonnaise, Dijon mustard, and a touch of sweet relish for that signature tangy-sweet balance that defines Mrs. Gerry's version.

What makes this copycat recipe truly special is the herb blend—fresh dill, chives, and parsley contribute bright, fresh notes that cut through the richness of the mayonnaise.

We fold everything together gently to maintain that perfect potato texture, then let it chill for at least 4 hours to allow flavors to meld completely. The result is a potato salad so authentic, even the original fans won't be able to tell the difference.

This recipe serves 12 generously, making it perfect for picnics, potlucks, or holiday gatherings. The flavor only improves with time, so it's ideal for meal prep. Let's get started on creating this legendary potato salad that will become your new signature dish.

Ingredients for mrs gerry's potato salad copycat

Twelve simple ingredients transform into legendary Mrs. Gerry's potato salad perfection.

The potatoes are non-negotiable—Yukon Golds hold their shape beautifully while absorbing flavor. Trader Joe's and Whole Foods carry them year-round, but local farmers markets often have the freshest batches. Boil them just until tender (about 12-15 minutes), then shock in ice water to stop cooking. The hard-boiled eggs should be peeled and chopped while still warm for easier handling. For the mayonnaise, Hellmann's or Duke's are reliable choices, but nothing beats homemade for that velvety texture—just be sure to use full-fat for maximum richness.

No sweet relish? Substitute a mix of finely chopped pickles and a pinch of sugar for that signature tang. Fresh herbs wilt fast, so buy just what you need—or freeze chopped herbs in ice cube trays for later use. The red onion can be swapped for green onion if you prefer milder flavor (use the same amount). For extra crunch, add 1/4 cup chopped celery seeds or 1/4 cup toasted slivered almonds after chilling. The butter in the dressing is crucial—don't skip it—it adds that signature buttery richness that defines the original recipe. If you're sensitive to dairy, use olive oil instead, but the flavor will be slightly different.

This salad tastes even better the next day as flavors meld completely—make it a day ahead for maximum impact. Store in an airtight container in the fridge for up to 5 days, though I usually eat it within 2. For potlucks, portion into individual containers so guests can serve themselves without cross-contamination. The dressing can be made separately and stirred in just before serving if you prefer a slightly lighter texture. If you're making this for a large crowd, double the recipe—it scales perfectly.

Step-by-step instructions for Mrs Gerry's potato salad copycat recipe

Here's the exact method to recreate that iconic buttery, herb-packed potato salad with crisp textures and balanced flavors.

Place the 3 lb Yukon Gold 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 vigorously, reduce heat to medium and cook for 12-15 minutes until the potatoes are tender when pierced with a fork.

Drain immediately and transfer the potatoes to a colander. Let them steam-dry for 2-3 minutes to remove excess moisture. This step is crucial - wet potatoes will make your salad soggy. While still warm, gently press each potato with a potato masher or fork to create rough edges that will better hold the dressing.

In a medium bowl, combine the 2 cups mayonnaise, 2 tbsp Dijon mustard, 0.5 cup sweet relish, 1 tbsp white vinegar, 2 tbsp butter, 0.5 tsp black pepper, and 1 tsp of the 1.5 tsp salt. Whisk vigorously until the butter is fully incorporated and the mixture is smooth and creamy.

This is where the magic happens - the tangy mustard and vinegar cut through the richness of the mayonnaise, while the sweet relish adds that signature balance. The butter contributes extra richness that makes this salad truly special. Taste and adjust seasoning if needed, adding more salt or vinegar as necessary.

Finely dice the 2 whole celery stalks, 0.5 cup red onion, 0.5 cup fresh dill, 0.25 cup fresh chives, and 0.25 cup fresh parsley. Place all chopped vegetables and herbs in a large mixing bowl. Chop the 6 whole hard-boiled eggs into small pieces and add them to the bowl as well.

For best results, use a sharp chef's knife and cut all ingredients into uniform pieces. The celery and onion should be very small dice, while the herbs can be slightly larger. The egg pieces should be roughly the same size as the potatoes for even distribution. This careful preparation ensures every bite has that perfect texture combination.

Add the warm, mashed potatoes to the bowl with the vegetables and herbs. Pour the dressing over the top and gently fold everything together using a large spatula or wooden spoon. Be careful not to overmix - just combine until everything is evenly distributed and coated with dressing.

Let the salad sit at room temperature for 10-15 minutes before serving. This resting time allows all the flavors to meld together perfectly. The potatoes will absorb some of the dressing, creating that ideal creamy yet slightly crisp texture that makes this potato salad so special.

Transfer the potato salad to an airtight container and refrigerate for at least 2 hours, preferably overnight. The longer it chills, the better the flavors will develop. When ready to serve, give it one final gentle stir to redistribute any dressing that may have settled.

This copycat version delivers that signature Mrs Gerry's flavor profile - creamy yet slightly crisp, with perfect balance of tangy, sweet, and herby elements. The key to success is using high-quality ingredients and allowing proper chilling time for the flavors to fully develop.

Best sauces and condiments for this mrs gerry's potato salad copycat

Classic Mayo Base

The foundation of Mrs. Gerry's potato salad is its rich, creamy mayo dressing. I recommend using Duke's mayonnaise for that signature buttery texture, but Hellmann's works well too. For extra richness, add 2 tbsp melted butter to the dressing mixture—this is what gives the original its velvety mouthfeel.

If you prefer a lighter version, substitute ¼ cup Greek yogurt for half the mayo, but the flavor will be slightly different. 🥛

Tangy Mustard Boost

The Dijon mustard (not yellow mustard!) provides the perfect tangy kick that balances the richness. Use 2 tbsp for authentic flavor, but if you don’t have Dijon, 1 tbsp yellow mustard + 1 tsp lemon juice works in a pinch.

For extra depth, add ½ tsp onion powder to the dressing—it enhances the savory notes without overpowering. Taste as you go, as the mustard’s sharpness can vary by brand.

Sweet Relish Secret

The ½ cup sweet relish is non-negotiable for that signature tangy-sweet balance. If you can’t find it, mix ¼ cup finely chopped dill pickles + 1 tsp sugar for a close substitute.

For a smoky twist, add ½ tsp smoked paprika to the relish mixture. This step is what sets this potato salad apart from basic mayo-based versions—don’t skip it! 🍅

Herb Freshness

The fresh herb blend is where this salad shines. Use ½ cup finely chopped dill (the star), plus ¼ cup each chives and parsley for brightness. If fresh herbs are expensive, 1 tbsp dried dill + 1 tsp dried parsley can work in a pinch, but fresh is best.

For a pop of color, add 1 tbsp finely chopped red bell pepper—it adds sweetness and visual appeal. Store herbs in the fridge in a sealed container with a paper towel to keep them crisp.

Acid Balance

The 1 tbsp white vinegar brightens the dressing and cuts through the richness. For a milder tang, use apple cider vinegar instead. If you prefer a fruitier note, swap in 1 tbsp lemon juice—just reduce the sweet relish to ¼ cup to balance the acidity.

A pinch of ½ tsp celery seed in the dressing adds a subtle earthy depth that mimics the original’s complexity. 💧

Crunchy Add-Ins

The 2 celery stalks and ½ cup red onion provide the perfect crunch. For extra texture, add ¼ cup toasted slivered almonds or ½ cup crispy fried shallots before serving.

If you love heat, toss in 1 tsp hot sauce or ½ tsp cayenne pepper—just be mindful of spice sensitivity. The 6 hard-boiled eggs add protein and creaminess, so don’t skip them! For a vegan version, use ¼ cup chopped avocado instead.
