This red potato salad uses mini red potatoes, tossed in a creamy sour cream, mayonnaise and mustard dressing, together with lots of diced green onion.
This Red Potato Salad is another Summer essential salad here. I love the simplicity of it and the tang of the sour cream in the dressing.
This salad can be made well ahead. The red potatoes hold up really well and keep their lovely texture, while the generous sauce keeps them moist. And speaking of the generous sauce, I know it looks like a lot, but trust me, because of the large pieces of potato, it’s really just right. A perfect balance of potato and sauce.
If you have chives on hand or in the garden, feel free to substitute chives for the green onion.
When buying your mini red potatoes, it’s best to select potatoes of similar size, so they cook at the same rate and are nicer in the salad. If your only choice is larger mini red potatoes, you may want to quarter them rather than halve them.
Be sure to watch your potatoes closely as they near done and cook only until tender.
If you happen to have a bit of bacon around, a bit of finely diced cooked bacon would be a nice addition to change this up.
Be sure to generously salt both your boiling water and your finished salad to really bring out the flavours.

This salad looks insane and like so many others have said sour cream is the be all end all. I can’t wait to make this today. I don’t have any dijon mustard and because yellow mustard is such a distinctly different flavor than dijon I don’t think I should use it because it might change the flavor in a way I won’t like, what do you think? Have you ever substituted yellow mustard for dijon? I just discovered your site today Jennifer and am looking forward to tasting some of these great recipes.
Hi Cyrus and thanks! I think I might try to add some mustard, as you may find the sour cream just a little “one note” without it. Maybe a bit of yellow mustard or if you have some, dried (powdered) mustard would be even better (just a bit, for the powdered 1/4-1/2 tsp).
Have been using mini potatoes for quite awhile now. Don’t know if I remember how to peel a regular potato! The Instant Pot does a great job cooking up mini potatoes every time!
Your dressing was a very tasty addition!
I rarely peel potatoes anymore, either :) Glad you enjoyed it!
I love the idea of sour cream in potato salad and can’t wait to make this! What type of red potatoes would you recommend using? The only ones I’ve ever tried have been disappointingly bitter. Also is there a difference between white flesh and yellow flesh red potatoes? The ones I tried had a slight yellow flesh so maybe that made a difference in the bitterness factor.
Hi Gemma, I tend to go for the red mini potatoes. I halve or quarter them (depending on how large they are) and boil them until just tender. I think the minis are generally white and I usually find them the perfect taste and texture for potato salad. Hope that helps! Enjoy :)
Potato salad is one of those summer staples that is just dangerous around me. Not to mention, I absolutely love sour cream. So you better believe I could devour this creamy deliciousness like nobodies business! It looks absolutely amazing, Jennifer!!

At summer picnics and bbqs potato salad is always what I first gravitate to. This looks so good Jennifer!
Thanks Mary Ann :)
I love how creamy this potato salad looks. I know there’s mayo in it but it looks so much lighter and creamier than a mayonnaise-based potato salad. So perfect for all these summer events coming up!
Thanks Chris and yes, even with the mayo, it is a a lighter sauce, for sure!
I love a good potato salad and this one fits the bill in so many ways! PS. Recently made your creme fresh with buttermilk and love it!
