This is not your average potato salad recipe. Don't get us wrong, there's definitely a time and place for the classic creamy, eggy traditional potato salad. This is not that time and place.
This grilled version using a homemade scallion pesto takes potato salad to a whole new level. If you've never tried grilled potato salad, you're going to love it. It's one of those straightforward yet super delicious summer side dishes you'll want to make again and again.
It's easy to make, too. Simply boil the potatoes until tender. While they're boiling, make the scallion pesto. Add the potatoes and onion to the grill until charred and then toss them with pesto and basil. It's delicious served warm but it's also a great salad to make ahead of time because it tastes great right out of the fridge, too!
Why you'll love it:
- It's easy to make
- It's super flavorful – grilling the potatoes and onions adds lots of delicious charred flavor
- It's healthier than traditional potato salad (no mayo or unwanted ingredients!)
- It's perfect for the grilling season
Grilled potato salad ingredients
Here's everything you'll need to make this grilled potato salad recipe:
- Potatoes – small or baby red potatoes are what we used for this recipe. No need to peel them, we always opt to keep the skins on for the health benefits (lots of fiber and nutrients) and a rustic feel.
- Red onion – red onion is a bit sweeter and more flavorful than regular cooking onion and grilling it makes it even sweeter.
- Oil – a neutral cooking oil will coat the veggies and prevent them from sticking to the grill.
- Sea salt – a flavor enhancer to make everything pop.
- Basil leaves – we love the classic taste of basil but you can use other fresh herbs that you love or have on hand.
Here's what you'll need for the scallion pesto:
- Olive oil – helps to unify the flavors and ingredients. A good quality olive oil can also add citrus, floral, or nutty notes.
- Green onions – we use the green parts only for a milder tasting pesto.
- Basil leaves – basil is a classic pesto ingredient and tastes lovely but you can also use a mix of herbs like parsley, cilantro, dill, or mint.
- Lemon juice – a squeeze of fresh lemon juice adds brightness and balance to pesto.
- Parmesan cheese – a small amount of this bold cheese adds lots of flavor and creaminess.
- Garlic – add more or less garlic to your desired taste.
How to make grilled potato salad
It's easy to make grilled potato salad by following a few simple steps:
- Start by boiling the potatoes then move on to preparing the pesto. Combine the pesto ingredients in a small food processor or blender and blend until it's smooth.
- Now, preheat your barbecue, quarter the boiled potatoes, and mix them with the red onion, oil, salt, and 2 tablespoons of the pesto.
- Next, grill potatoes and onions until they begin to char.
- Transfer the cooked potatoes and onions to a large bowl and toss with the rest of the pesto and some basil. Sometimes we like to add a few grinds of fresh black pepper for an extra kick.

FAQS
We love the taste and creamy texture of red-skinned potatoes but you can use any small potatoes that are available to you.
Definitely! This is one of those salads you can eat warm or cold. It keeps well in the fridge in an air-tight container for up to 3 days.
Yes! To make it dairy free, simply swap the parmesan cheese for a dairy-free alternative, or use our dairy-free pesto recipe instead.
For sure! Bacon would add a lot of flavor and some extra protein. Cook the bacon in strips and once it's cool enough to touch, crumble it into the salad before giving it all a stir.

I am 1000% one of those people who have avoided mushy mayo-dripping potato salad. I love the looks of your version, though! So fresh and vibrant, seriously gorgeous photos!
Thank you so much, Denise!! 🙂
Prettiness definitely counts! I love this type of potato salad. I actually a bit of a mayonnaise hater, so I do mayo free potato salads or use yogurt instead. But I’m excited to try your version. And love that so much of this salad is grilled!
I’m going to have to try using yogurt next time I make a creamy potato salad.. Sounds so much better than mayo!
I will admit, and I’m not ashamed, that I love ALL forms of potato salad. However, I totally prefer a grilled potato salad that is light on (or without) mayonnaise. This potato salad, you have here, is serious stuff- this is jazzed up, fancy pants potato salad.. this is the kind of potato salad dreams are made of!! I LOVE this, Kristen- and the quail egg on top is just sheer perfection ♡ I’ve got to make this! Pinned!!!
Nothing to be ashamed of there! Creamy potato salad can be so good too … if only there were a way to make it look pretty!
Thanks for pinning!
I love potato salad. It’s the perfect side dish for summer barbecues. I love that you grilled it! Sounds amazing!
Thanks you so much! It really was delicious. 🙂
