Additional Potato Salad Toppings & Ingredients

I am an onion lover (to me, more is MORE — always!) so when we made this side and I had red onions on hand, I diced some and tossed them in. If you like red onions, I would 100% recommend this addition — again, not necessary, but I love it this way. Other possibilities — bacon crumbles, dill, or hard boiled egg (I don’t eat eggs but my mom likes this potato salad with some diced egg included). Our favorite champagne vinaigrette is Trader Joe’s; they were out of stock during my last visit but if you see some, grab it to try!

    This sounds like a lighter and more refreshing change from a mayo-based one – ideal for hotter weather and lovely and straightforward! I shall have to try to home-replicate TJ’s champagne vinaigrette as I can’t get it here in the U.K. I would suggest that, as with all starch-based salads, that you try dressing the potatoes whilst they are still warm as they will absorb more flavour.

      Hi Sally, Thanks so much for taking the time to stop by! It was definitely a plus for me to have the “ready made” vinaigrette. It seemed like the three ingredients were all that really needed. I certainly appreciate your tip. I consciously waited until the potatoes had cooled so that the dressed salad would not be so tangy. You certainly sound like a phenomenal cook and I bet your dressing and the resulting salad will be delicious!
