This Creamy Pea and Potato Salad is a simple, comforting side dish made with tender potatoes, sweet green peas, crisp red onion, and a smooth, tangy dressing. Every bite combines soft potatoes with fresh little bursts of sweetness from the peas and just enough onion to balance the creamy sauce.
It is perfect for family dinners, summer cookouts, potlucks, picnics, holiday tables, and make-ahead lunches. Because it tastes even better after chilling, you can prepare it several hours before serving.
Why You’ll Love This Creamy Salad
This recipe uses inexpensive ingredients but delivers plenty of flavor.
The potatoes make it filling, the peas add color and sweetness, and the red onion brings a little crunch. A mayonnaise-and-sour-cream dressing coats everything without needing a complicated sauce.
It is also easy to customize. You can add eggs, bacon, cheddar, celery, fresh herbs, or even diced pickles depending on what you have available.
Ingredients
- 2 pounds potatoes
- 2 cups frozen green peas
- ½ small red onion, finely diced
- ¾ cup mayonnaise
- ½ cup sour cream
- 1 tablespoon Dijon mustard
- 1 tablespoon apple cider vinegar
- 1 teaspoon sugar or honey, optional
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¾ teaspoon salt, or to taste
- ½ teaspoon black pepper
- 2 tablespoons chopped fresh parsley or dill, optional
Choosing the Best Potatoes
Yukon Gold potatoes are an excellent option because they have a naturally creamy texture while holding their shape reasonably well.
Red potatoes also work beautifully.
Russet potatoes can be used, but they contain more starch and tend to break apart more easily. If you prefer a very soft and creamy potato salad, that may actually be desirable.
Whatever variety you choose, cut the potatoes into similar-size cubes so they cook evenly.
How to Cook the Potatoes
Peel the potatoes if desired, or leave some skin on for additional texture.
Cut them into approximately ¾-inch cubes.
Place the potatoes in a large saucepan and cover them with cold water.
Add a generous pinch of salt.
Bring to a boil, then reduce the heat and simmer until the potatoes are fork-tender but not falling apart, usually around 8–12 minutes depending on their size.
Drain thoroughly.
Allow the potatoes to cool before combining them with the creamy dressing.
Prepare the Green Peas
Frozen peas are particularly convenient for this recipe.
Bring a small pot of water to a boil and add the frozen peas.
Cook them only briefly, approximately 1–2 minutes, until bright green and tender.
Drain immediately and rinse under cold water.
This stops the cooking process and helps preserve their color and slightly firm texture.
Drain very well before adding them to the salad.
Make the Creamy Dressing
In a medium bowl, combine the mayonnaise and sour cream.
Add Dijon mustard, apple cider vinegar, garlic powder, onion powder, salt, and black pepper.
If you like a subtle sweet-and-tangy balance, add a teaspoon of sugar or honey.
Whisk until completely smooth.
Taste the dressing before adding it to the salad and adjust the salt, pepper, or vinegar as necessary.
Assemble the Salad
Place the cooled potatoes in a large mixing bowl.
Add the drained peas and finely diced red onion.
Pour approximately three-quarters of the dressing over everything.
Using a large spoon or silicone spatula, gently fold the ingredients together.
Avoid stirring aggressively because this can break the potatoes and turn the salad into mashed potatoes.
Add additional dressing until you reach your preferred creaminess.
Chill Before Serving
Cover the bowl and refrigerate the salad for at least 1–2 hours.
Chilling allows the flavors of the onion, mustard, vinegar, and seasonings to blend into the creamy dressing.
Before serving, stir gently.
If the potatoes have absorbed a lot of dressing, you can fold in a small spoonful of mayonnaise or sour cream to restore the creamy texture.
Add Hard-Boiled Eggs
Hard-boiled eggs make this simple potato salad even more substantial.
Cook and cool 3–4 eggs, peel them, and chop them into bite-size pieces.
Gently fold them into the salad after combining the potatoes and peas.
You can also reserve one sliced egg for the top of the serving bowl.
Bacon and Cheddar Variation
For an extra-rich version, add:
- ½ cup cooked crumbled bacon
- ¾ cup shredded cheddar cheese
- 2 tablespoons chopped green onions
The combination of potatoes, cheddar, bacon, peas, and creamy dressing creates a hearty side dish that works particularly well for barbecues and family gatherings.
Add More Crunch
If you prefer additional texture, finely chopped celery is an excellent addition.
Diced cucumber can also work, although it contains more water and is best added shortly before serving.
Finely chopped pickles or relish provide another option and give the salad a sharper, tangier flavor.
Fresh Herbs Make a Difference
Dill works especially well with potatoes, peas, and creamy dressings.
Fresh parsley gives the salad a lighter flavor, while chopped chives provide a mild onion note.
You don’t need much. A couple of tablespoons of fresh herbs can brighten the entire bowl.
Make the Dressing Lighter
For a slightly lighter dressing, replace some of the mayonnaise with additional plain Greek yogurt.
For example, combine:
- ½ cup mayonnaise
- ½ cup plain Greek yogurt
- ¼ cup sour cream
The dressing remains creamy but gains a little extra tanginess.
What to Serve With Creamy Pea and Potato Salad
This salad pairs beautifully with many casual meals.
Serve it alongside:
- Grilled chicken
- Burgers
- Baked chicken
- Pulled pork
- Sandwiches
- Roasted meat
- Grilled vegetables
- BBQ dishes
It also works as part of a larger buffet with coleslaw, pasta salad, corn, fresh vegetables, and rolls.
Perfect for Potlucks and Cookouts
Because this recipe can be made ahead, it is convenient for gatherings.
Prepare the salad the evening before, cover it tightly, and refrigerate.
Before serving, give it a gentle stir and adjust the seasoning.
Since the dressing contains mayonnaise and other perishable ingredients, keep the salad properly chilled. For outdoor gatherings, place the serving bowl over ice and return leftovers to refrigeration promptly.
Common Mistakes to Avoid
Overcooking the potatoes: They should be tender but still able to hold their shape.
Mixing while the potatoes are very hot: This can make the dressing oily and cause the potatoes to break apart.
Overcooking the peas: Peas need very little cooking. Keeping them bright green also makes the finished salad more attractive.
Using watery vegetables without draining them: Excess moisture can thin the dressing.
Adding too much onion: Raw red onion has a strong flavor. Start with a modest amount and add more if desired.
Overmixing: Fold everything together gently.
How to Store Leftovers
Transfer leftovers to an airtight container and keep them refrigerated.
For best quality, enjoy the salad within approximately 3–4 days.
Don’t leave the salad at room temperature for more than about two hours, or one hour when temperatures are above 90°F (32°C).
If you’re uncertain how long it has been unrefrigerated, it’s safer to discard it.
