- Feeds: 6 as a side dish
- Difficulty: Beginner-friendly
- Adaptability: Easily customized for different dietary needs
What You’ll Need
For the Potato Base:
- 4 medium Yukon Gold potatoes, chopped into approximately 1-inch cubes
- 3 eggs
- 1/2 medium red onion, finely diced
- 1 medium apple, peeled or unpeeled (unpeeled adds more color), chopped into small cubes
- Green onions, sliced (for garnish)
For the Creamy Dressing:
- 4 heaping tablespoons mayonnaise
- 3 tablespoons extra virgin olive oil
- 3 tablespoons apple cider vinegar
- 2 tablespoons yellow mustard
- 2 tablespoons fresh lemon juice
- Salt and freshly ground black pepper, to taste

Prep & Cook
- Prepare the Eggs: Place eggs in a medium saucepan and cover with cold water by 1 inch. Bring to a boil over medium-high heat, then cover, remove from heat, and let sit for 10 minutes. Transfer eggs to an ice bath to cool completely before peeling and chopping.
- Cook the Potatoes: Meanwhile, place potato cubes in a large pot and cover with cold water. Add a generous pinch of salt and bring to a boil. Reduce heat to maintain a gentle simmer and cook until potatoes are fork-tender but still hold their shape, about 8-10 minutes. Drain thoroughly and allow to cool slightly.
- Mix the Dressing: In a large bowl, whisk together mayonnaise, olive oil, apple cider vinegar, yellow mustard, and lemon juice until smooth and well combined. Season generously with salt and freshly ground black pepper.
- Prepare the Apple: After dicing the apple, place the cubes in a bowl of cold water with the juice from 1/2 lemon to prevent browning. If you’re making the salad in advance, consider adding the apple just before serving instead.
- Combine Everything: Drain the apple cubes thoroughly. Add the slightly cooled potatoes, chopped eggs, diced red onion, and apple cubes to the bowl with the dressing. Gently fold everything together until evenly coated, being careful not to break up the potatoes too much.
- Chill and Serve: For best results, refrigerate the potato salad for at least 1 hour to allow flavors to meld. Before serving, taste and adjust seasoning if needed, then transfer to a serving dish and garnish with sliced green onions.


Secrets from Our Kitchen to Yours
- The Apple Trick: After dicing the apple, always place the cubes in cold water with lemon juice to prevent browning. If making the salad in advance, add the apple just before serving to maintain its crispness.
- Potato Selection Matters: Yukon Gold potatoes have the ideal texture balance, remaining firm enough to hold their shape while still absorbing the flavorful dressing.
- Dressing Temperature: Mix your dressing ingredients while the potatoes are still slightly warm. The warm potatoes will absorb more flavor than completely cooled ones.
- Egg Perfection: The 10-minute method for hard-boiled eggs ensures perfectly cooked yolks without that unappetizing green ring that can form around overcooked yolks.
- Storage Wisdom: This potato salad will keep well in an airtight container in the refrigerator for up to 3 days. The flavor actually improves after the first day as all the ingredients have time to mingle.
Serving Suggestions
Mamy’s Secret Ingredient Potato Salad shines as:
- The perfect companion to grilled meats at summer barbecues
- A substantial side for fried chicken or baked ham
- A potluck superstar that always disappears first
- The ideal make-ahead side for busy weeknight dinners
- A picnic essential that travels well in cooler weather
For a complete meal, pair with rotisserie chicken and a simple green salad dressed with olive oil and lemon juice. The combination of flavors—savory, tangy, and subtly sweet—complements almost any main dish.
Put Your Spin on It
- Protein Boost: Add diced cooked chicken breast or crumbled bacon for a heartier version that can stand alone as a main dish.
- Apple Color Swap: Substitute red apple with green apple (like Granny Smith) for an extra tart, special flavor that adds another dimension to the salad.
- Fall Harvest Edition: Replace the apple with diced pear and add toasted pecans for a seasonal autumn variation.

Common Questions
Can I make this potato salad ahead of time? Absolutely! In fact, the flavors develop beautifully after a few hours in the refrigerator. If making more than 3 hours ahead, consider adding the apple just before serving to maintain its crispness.
What kind of apple works best in this recipe? Firm, sweet-tart varieties like Honeycrisp, Pink Lady, or Fuji work wonderfully. Their crispness holds up in the salad, and their balanced flavor complements the other ingredients perfectly.
Can I use a different type of mayonnaise? Absolutely! While traditional mayonnaise works best for this recipe, you can try using a high-quality avocado oil mayo or homemade mayonnaise if you prefer. Just keep the proportions the same for best results.
How can I make this potato salad for a larger crowd? This recipe doubles or triples beautifully. Just maintain the same ratios and consider making the dressing separately, then tossing with the solid ingredients just before serving.
What’s the best way to prevent the potatoes from becoming mushy? Start the potatoes in cold water, simmer gently rather than boiling vigorously, and test frequently with a fork. The perfect potato for potato salad should be tender enough to pierce easily but still hold its shape when cut.
