Roasted Balsamic Rosemary Potato Salad

My Roasted Balsamic Rosemary Potato Salad says sayonara to mayonnaise!  Instead, these rosemary flecked potatoes are roasted with red onion  and garlic and dressed with a light touch of extra-virgin olive oil and balsamic vinegar.  Served warm or at room temperature, this potato salad aims to please.

The temperatures are rising and we’re finally able to eat more of our meals outside.  FINALLY!  And with warm weather holidays approaching that signal getting together with friends and dine outside alfresco, it can only mean one thing.  It’s potato salad season!  Sure, you can have potato salad any time of year, but I enjoy it most when it’s warm enough to be outside.

As much as I love potato salads, there’s one thing I don’t care for – gloppy dressings that take away from the star of the show.  My one true vegetable love, Idaho® potatoes.  I can’t even tell how how loud I squealed when I opened a box of these gorgeous fingerling potatoes straight from the farm in Idaho.  It was like Christmas!  Gorgeous red, white and purple potatoes just begging to put to use.  Not that they had to beg, I was already scheming!

My Roasted Balsamic Rosemary Potato Salad says sianara to mayonnaise!  Instead, these potatoes are roasted with red onion and dressed with a light touch of extra-virgin olive oil and balsamic vinegar and flecks of freshly chopped rosemary.  Be still my heart!  But I haven’t even mentioned the best part!  Not only can you enjoy this salad straight from the oven while still warm, but it’s also perfect for serving room temperature.  No need to worry about your potato salad spoiling at your next potluck, this side is low maintenance. 

The only problem is that since it can be served at room temperature, my fingers can’t stay away from the bowl and before I know it, there’s not much salad left to share with my friends or family.  Oops!

Those purple potatoes?  My daughters were truly enthralled with them and picked out every last one of them before eating the others.  Do they taste different than the red and white?  No.  They simply thought they were the prettiest.

There’s nothing wrong with a pretty potato salad, now, is there?

  1. Nothing at all wrong with a pretty potato salad. And I love those purple potatoes too. I may be guilty of digging those out to have all to myself. Maybe. Ahem.

  2. I love balsamic and rosemary together! Your potato salad looks just amazing! I could eat the whole recipe!!

  3. I think I have to try these, I’m obsessed with anything Balsamic recently. Plus I love the roasted part!

  4. I love everything about this, including the stunning photos!!

  5. What a beautiful potato salad recipe. Love the addition of rosemary!

  6. Wish I could snip one of those beauties out of your photos, Melanie. Kudos to you for only slipping one or two out of the bowl. Your dairy free potato salad is indeed very elegant and perfect for any occasion =) P.s. Pinned of course!

  7. simple roasted potatoes with fresh rosemary and a balsamic dressing on top?! I love this! and could probably eat that entire bowl!

  8. I am exactly the same way – potato salad of this sort (okay, any sort) is not safe sitting on the counter top when I am around! I am totally digging your addition of Balsamic – and I know that I need to try it asap. Yummmmmmmmy!

  9. Perfection in a bowl – I love that you baked the potatoes for your potato salad.

  10. Roasted potatoes in a salad sound wonderful. I also really like that you made this with balsamic vinegar. Such a great recipe!

  11. Your photos are amazing and your potato salad really lets the Idaho potatoes shine!

      Thank you so much, Renee – we’ve eaten this salad three times since I originally created it. I think we’re smitten!

  12. What a gorgeous and refreshing potato salad…love all the pretty colors!

  13. LOVE your photography and food styling here, Melanie! So creative. And this salad, well…it’s just lovely. I’ve never thought to put balsamic in a potato salad, but now I wonder why I haven’t!

  14. I love anything with balsamic vinegar and I love roasted potatoes, so I know I’ll love this potato salad!

  15. Balsamic and rosemary are my favorite combination with potatoes! This potato salad is perfection, and your photos are gorgeous!

  16. Oh my goodness! This looks amazing – I’m totally a potato salad kind of girl and the balsamic rosemary is a classic :)

    • melanie says:

      Thanks, Em! We’re a big fan of this potato salad – if only I could keep my hands out of the bowl before serving!

  17. Your potatoes look like they are roasted to absolute perfection!

  18. I love my favorite balsamic vinegar on brussel sprouts, so I have no idea how I have never thought to try it on potatoes! Fabulous recipe!

  19. Could this potato salad be any more beautiful? I think not! I would probably not be able to bring myself to share this one; I’d want it to myself!

  20. I do exactly as your daughters do….eat the purples first. They are just more FUN!

  21. Great minds! Love your version of roasted potato salad and I have everything at home. This must be made this weekend.
