Recipe Details

  • Prep Time: 15 minutes

  • Cook Time: 15–20 minutes

  • Chilling Time: 1 hour

  • Total Time: Approximately 1 hour 35 minutes

  • Servings: 6

  • Course: Side dish

  • Cuisine: American-inspired

  • Difficulty: Easy

Ingredients

  • 2 pounds potatoes, Yukon Gold or red potatoes

  • ½ medium red onion, finely chopped

  • ¾ cup mayonnaise

  • 2 tablespoons sour cream or plain Greek yogurt

  • 1 tablespoon Dijon mustard

  • 1 tablespoon apple cider vinegar

  • 2 tablespoons fresh parsley or dill, chopped

  • ½ teaspoon salt, or to taste

  • ½ teaspoon black pepper

  • ½ teaspoon garlic powder, optional

  • 2 hard-boiled eggs, chopped, optional

  • 1 tablespoon chopped chives, optional

Instructions

Step 1: Prepare the Potatoes

Wash the potatoes thoroughly. Peel them if desired, or leave the skins on for extra texture and color.

Cut the potatoes into evenly sized chunks, approximately 1-inch pieces. Keeping the pieces similar in size helps them cook evenly.

Step 2: Boil the Potatoes

Place the potatoes in a large pot and cover them with cold water. Add a little salt to the water.

Bring to a boil over medium-high heat, then reduce the heat and simmer for approximately 12–18 minutes, depending on the size of the pieces.

Check the potatoes with a fork. They should be tender but still hold their shape. Avoid overcooking, or the salad may become mushy.

Step 3: Drain and Cool

Drain the potatoes carefully in a colander. Allow them to cool for approximately 10–15 minutes.

The potatoes should be cool enough to handle before adding the mayonnaise dressing. Slightly warm potatoes can absorb some of the dressing, but adding mayonnaise while they are very hot may make the salad overly soft.

Step 4: Prepare the Red Onion

Peel the red onion and chop it finely.

If you prefer a milder onion flavor, soak the chopped onion in cold water for 5–10 minutes. Drain and pat dry before adding it to the salad.

Step 5: Make the Creamy Dressing

In a large mixing bowl, combine the mayonnaise, sour cream or Greek yogurt, Dijon mustard, and apple cider vinegar.

Add the salt, black pepper, and garlic powder if using. Whisk until smooth and creamy.

Taste the dressing and adjust the mustard, vinegar, or seasoning according to your preference.

Step 6: Add the Potatoes

Transfer the cooled potatoes to the bowl containing the dressing.

Use a large spoon or spatula to gently fold the potatoes into the dressing. Avoid vigorous mixing, as this can break the potatoes apart.

Step 7: Add the Red Onion and Herbs

Add the chopped red onion and fresh parsley or dill. If desired, gently fold in the chopped hard-boiled eggs and chives.

Mix until the ingredients are evenly distributed and the potatoes are coated with the creamy dressing.

Step 8: Chill the Salad

Cover the bowl and refrigerate for at least 1 hour.

Chilling allows the flavors to blend and gives the dressing time to coat the potatoes. If the salad becomes too thick after chilling, stir in a spoonful of mayonnaise, yogurt, or a little lemon juice.

Step 9: Garnish and Serve

Before serving, gently stir the salad and taste for seasoning. Sprinkle extra fresh parsley, dill, or chives over the top.

Serve chilled alongside grilled chicken, burgers, roasted vegetables, or barbecue dishes.

Recipe Notes

  • Best potatoes: Yukon Gold potatoes have a creamy texture and hold their shape well. Red potatoes are another excellent choice.

  • Red onion: Finely chopping the onion distributes its flavor throughout the salad.

  • Mayonnaise: Use your preferred mayonnaise. Light mayonnaise can reduce calories and fat.

  • Greek yogurt: Replacing some mayonnaise with plain Greek yogurt creates a tangier dressing and adds protein.

  • Fresh herbs: Dill, parsley, and chives complement the creamy dressing.

  • Optional eggs: Hard-boiled eggs add richness and protein.

  • Mustard: Dijon mustard provides a gentle tang, but regular mustard can also be used.

  • Make-ahead option: Prepare the salad several hours in advance and keep it refrigerated until serving.

Tips for the Best Potato Salad

  1. Start cooking the potatoes in cold water so they cook more evenly.

  2. Avoid overcooking the potatoes; they should be tender but not falling apart.

  3. Drain the potatoes well to prevent watery dressing.

  4. Let the potatoes cool before mixing in the mayonnaise.

  5. Chop the red onion finely for a more balanced flavor.

  6. Fold the ingredients gently to keep the potato chunks intact.

  7. Chill the salad before serving for the best flavor.

  8. Taste again after chilling because cold temperatures can dull the perception of seasoning.

  9. Keep the salad refrigerated when not serving, especially in warm weather.

Serving Suggestions

Creamy Red Onion Potato Salad pairs well with:

  • Grilled chicken or turkey

  • Barbecue pork ribs

  • Grilled fish

  • Hamburgers and sandwiches

  • Roasted vegetables

For a lighter meal, serve a moderate portion with grilled lean protein and a fresh vegetable salad.

Storage and Food Safety

Refrigerator: Store the potato salad in an airtight container for up to 3–4 days.

Serving safety: Do not leave mayonnaise-based potato salad at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).

Freezing: Freezing is not recommended because mayonnaise-based dressings can separate and the potatoes may become grainy after thawing.

Leftovers: Refrigerate promptly and discard any salad that has been left out too long or shows signs of spoilage.

Questions and Answers

Q1: Can I make potato salad the day before?

Yes. Prepare it a day ahead, cover it, and refrigerate. Stir gently before serving and adjust the seasoning if needed.

Q2: Which potatoes are best for potato salad?

Yukon Gold and red potatoes are excellent because they hold their shape well after boiling. Russet potatoes can also be used, but they are softer and more likely to break apart.

Q3: How can I make the onion flavor milder?

Soak the chopped red onion in cold water for 5–10 minutes, then drain it thoroughly before adding it to the salad.

Q4: Can I make this recipe without mayonnaise?

Yes. Replace the mayonnaise with plain Greek yogurt or use a mixture of Greek yogurt, mustard, and a little olive oil. The taste and texture will be different.

Q5: Can I add eggs?

Absolutely. Two chopped hard-boiled eggs add a classic flavor and make the salad more filling.

Q6: Why is my potato salad watery?

The potatoes may not have drained sufficiently, or they may have been mixed with the dressing while very hot. Drain them thoroughly and allow them to cool before mixing.

Q7: Can I use dried herbs instead of fresh herbs?

Yes. Use a smaller quantity because dried herbs have a more concentrated flavor. Add a little, taste, and adjust.

Q8: Is potato salad suitable for people with diabetes?

Potatoes contain carbohydrates and can raise blood glucose. People with diabetes may still be able to enjoy a suitable portion, depending on their individual meal plan. Pairing it with non-starchy vegetables and lean protein can help create a more balanced meal.

Q9: How do I make the dressing tangier?

Add a little extra Dijon mustard, apple cider vinegar, or lemon juice, tasting as you go.

Q10: Can I make this potato salad dairy-free?

Yes. Omit the sour cream or Greek yogurt and use a dairy-free mayonnaise. Check ingredient labels if you have a dairy allergy.
