This easy grilled potato salad is served with a crème fraîche dressing and dill. Perfect for your summer BBQs! It’s altogether delicious, easy and elegant, in a rustic kind of way.
Ingredients and Substitutions
Potatoes – You’ll want to use a waxy potato for these, either a red, white or yellow-fleshed potato, as they hold their shape well. Avoid starchy potatoes like Russets. A medium sized potato is best, for nice sized, but not huge chunks. Aiming for similar sized potatoes will ensure that they cook evenly. I used yellow-fleshed potatoes for my dish here, but white or red potatoes would work nicely as well.
Crème fraîche – this is fairly easy to find in the dairy section, usually found in the sour cream or yogurt section. I’ve included the very easy recipe for making your own Crème fraîche at home using only heavy cream and buttermilk. Note that you’ll need to make this a day or so ahead of when you want to use it to make these potatoes. The Crème fraîche recipe will also make more than you need for this potato recipe, so you’ll have extra to use for other dishes. You’ll use about half for the potatoes.
Whole Grain Mustard – this is the type of mustard that has whole mustard seeds in it. I am a fan of the Maille™ version.
- The potatoes can also be grilled on a hot grill pan on the stove-top if you don’t have access to a BBQ grill.
- When adding water to your dressing, add just enough to thin it to the point where it will fall off a spoon. How much water you have to add will depend on how thick your Crème fraîche is to start with.
- Be sure to season with salt and pepper along the way, starting with salting the boiling water for the potatoes, then seasoning before grilling and a bit more on the plate. Don’t forget to add a little seasoning to the salad dressing, as well.
- I used homemade Crème fraîche here. As mentioned, it sat on my windowsill for 20 hours, then in the refrigerator overnight. It was the consistency of cream cheese at that point, but may not be as thick if it is refrigerated for less time. In fact, if making your own Crème fraîchea nd don’t have a chance for it to refrigerate for too long, you may not need to add any water at all.
How to Make Crème fraîche at Home
In a medium jar, stir together 1 cup of heavy, 35% whipping cream (not ultra-pasteurized) and 1 Tbsp. buttermilk. Set a lid on top, but don’t twist to seal it (to allow air to escape, but to keep dust and things out). Set on your counter or window sill for 12-24 hours, or until the mixture resembles stirred sour cream. The time it takes to that point will vary depending on the temperature of your room. Mine took about 20 hours. At that point stir the mixture well, then transfer to the fridge, again, topping with a lid but not twisting to seal it, as it will continue to process). Refrigerate a further 6 hours or longer, or until it is the consistency of cream cheese.
The beautiful of this dish is that it comes together really quickly. The potatoes need to boil first, but as they are sliced, they boil up quickly. You could even do the boiling earlier in the day and refrigerate the potato slices until it’s time to grill. The easy Crème fraîche and grainy mustard dressing can also be made ahead. When it’s time to eat, simply grill the potatoes, top with the dressing and fresh dill and they’re ready to enjoy.
Get the Recipe: Grilled Potato Salad
- 5 medium red, white or yellow fleshed potatoes, washed but not peeled
- 2 Tablespoons extra virgin olive oil, for brushing
- Salt and freshly ground pepper
- 1/2 cup Crème fraîche, (See Note below to learn how to make creme fraiche at home!)
- 1 Tablespoon whole grain mustard
- 1 Tablespoon water
- 2-3 Tablespoons fresh dill, chopped
- Prepare the dressing by combining the Crème fraîche and grainy mustard in a bowl. Add a bit of salt and freshly ground pepper. Next, add just enough water to thin the mixture so that it can drop from a spoon, about 1 Tbsp. or a bit more, if needed. (If your Crème fraîche is thin to start with, you may not need to thin with water). Cover and refrigerate until needed.
- Prepare the potatoes by cutting lengthwise into 1/4-inch slices, discarding the rounded outside slices. Bring a large pot of salted water to a boil, then add the potato slices and boil until just tender, about 8-10 minutes. Drain, then remove the slices to an even layer on a baking sheet. Brush top side of the potato slices with olive oil and sprinkle with salt and pepper.
- Heat BBQ or grill pan to high heat. Place slices on the grill, oiled side down and cook until lightly charred, on the underside, about 5 minutes. Before flipping, brush the top side of the potatoes with more oil and sprinkle with salt and pepper. Flip potatoes and cook the other side until lightly charred, a further 5 minutes. *Can also be made in a hot grill pan on the stove-top.
- Remove potatoes to a cutting board. Slice in half lengthwise and toss into a serving bowl or skillet. Sprinkle with a bit more salt and pepper. Drizzle with creme fraiche dressing and garnish with chopped fresh dill.

This is by far the prettiest potato salad that I’ve ever seen! The dressing sounds perfect for me as I don’t typically do mayo.
Thanks so much, Sara. The creme fraiche is really lovely on this. Very light, with a little tang.
I love grilled potatoes and your dressing sounds fabulous!
Thanks Laura :)
This is a beautiful and delicious looking potato salad. I love homemade creme fraiche. Whenever I’m going to have weekend guests I’ll make a jar to have on hand for lots of fun splurges. I never thought to use it on potato salad though. I sounds wonderful with the grainy mustard!
Thanks Chris and yes, it’s really a lot like sour cream on potatoes, and that’s a good thing always :)
I love potato salad and this may just be my new go to warm one to pair with almost anything!

I love a warm potato salad Jennifer and this one sounds just delicious. I love the addition of dill and some grainy mustard! I’ve never tried to make homemade creme fraiche. Can’t wait to give it a try.
Thanks Mary Ann and you have to try making the Creme Fraiche. It’s one of those things that once you do, you’ll wonder why you haven’t been doing it for years!
I was surprised how much I loved a grilled potato salad but need to make it again especially with your Creme Fraiche Grainy Mustard Dressing – it sounds and looks wonderful! Sharing!
Thanks Tricia. We really enjoy it, too. I also love making my own Creme Fraiche to use in this dish, because I always have a bit left for other things :)
This is brilliant! I love the idea of the warm potatoes with the cool dressing!
Thanks Sue. It was really nice and a change from the usual :)
I’m just staring at these with my mouth hanging open, lol. Such a special dish, Jennifer! I love the flavors and ease of prep. And your pan! I need one of those….or 4 or 5 ! :)
Thanks Robyn :) I love my copper pots and pans. Most of them I’ve collected from vintage stores, where they looked beyond salvaging, and cleaned them up. Ketchup! It’s a wonder copper cleaner.
