French-Style Potato and Green Bean Salad tastes bright, herby, and briny with tender potatoes, crisp-tender green beans, and a punchy Dijon-shallot vinaigrette. It suits busy cooks, picnic lovers, and anyone who wants a make-ahead side in about 35 minutes. I learned this combo on a trip through Provence and still reach for it whenever my crisper fills with herbs.
Why Choose This French-Style Potato and Green Bean Salad
French-Style Potato and Green Bean Salad gives you creamy potatoes, snappy green beans, and a vinaigrette that sings without mayo. You can serve it warm, room temp, or chilled, and it travels like a champ for potlucks or work lunches.
Ingredients You Need
- Small Yukon Gold or yellow potatoes, 1.5 pounds, halved or quartered (waxy potatoes hold shape best)
- Green beans or haricots verts, 12 ounces, trimmed (pre-trimmed bags save time; haricots verts cook faster)
- Shallot, 1 small, minced
- Dijon mustard, 2 teaspoons (Maille or Edmond Fallot both taste great)
- Red wine vinegar, 3 tablespoons
- Fresh lemon juice, 1 tablespoon, optional for extra brightness
- Extra-virgin olive oil, 6 tablespoons (use a fruity, medium-bodied oil)
- Capers, 2 tablespoons, drained and chopped
- Fresh herbs: 2 tablespoons chopped parsley, 1 tablespoon chopped tarragon, 1 tablespoon snipped chives
- Garlic, 1 small clove, grated or mashed
- Sea salt and freshly ground black pepper
- Optional add-ins: 1 tablespoon minced anchovy or anchovy paste, 1 tablespoon chopped cornichons, 1/3 cup niçoise or Kalamata olives, 2 hard-cooked eggs in wedges
Equipment:
- Large pot and colander
- Large bowl and small bowl or jar with lid
- Whisk or fork
- Chef’s knife and cutting board
- Sheet pan or wide plate for cooling
- Tongs or spoon
Pantry shortcuts and swaps:
- Use pre-trimmed green beans and steam-in-bag potatoes to cut prep time.
- Swap sherry vinegar for red wine vinegar for a rounder finish.
- Use a small red onion if you lack shallot; rinse slices under cold water to soften bite.
- Skip anchovy and double the capers for a vegetarian version.
How to Make French-Style Potato and Green Bean Salad
Step 1: Cook the potatoes
- Add potatoes to a large pot and cover with cold, well-salted water by 1 inch. Bring to a gentle boil, then lower to a lively simmer. Cook until just tender when pierced, 10 to 12 minutes for small chunks.
- Drain and spread potatoes on a sheet pan to steam off excess moisture for 3 minutes.
Step 2: Blanch the green beans
- Refill the pot with fresh salted water and bring to a boil. Add green beans and cook until crisp-tender and bright, 2 to 3 minutes for haricots verts or 3 to 4 minutes for standard beans.
- Plunge beans into an ice bath to set color, then drain well and pat dry.
Step 3: Make the Dijon-shallot vinaigrette
- In a small bowl or jar, combine shallot, garlic, Dijon, red wine vinegar, lemon juice, 1 teaspoon salt, and several grinds of pepper. Whisk to combine, then slowly stream in olive oil while you whisk, or shake in a jar until emulsified.
- Stir in capers. Taste and adjust acid, salt, and pepper.
Step 4: Dress the warm potatoes
- Transfer warm potatoes to a large bowl and pour over half the vinaigrette. Toss gently so the potatoes absorb that flavor while still warm.
- Fold in half the herbs. Let sit 5 minutes.
Step 5: Add beans and finish
- Add green beans to the bowl and toss with the remaining vinaigrette. Fold in remaining herbs, olives or cornichons if using, and anchovy if you like a brinier kick.
- Taste and adjust with a pinch of salt, a splash of vinegar, or a drizzle of olive oil. The salad should taste bright, well-seasoned, and balanced.
Step 6: Rest and serve
- Serve warm right away, or let it stand 10 to 15 minutes so flavors mingle. You can also chill it for 20 to 30 minutes if you prefer a cooler salad.
- Toss again before serving and add a few extra chives on top for color.
Tips & Common Mistakes
- Salt the cooking water generously so the potatoes taste seasoned from the inside out.
- Cut potatoes into even pieces so they cook at the same rate.
- Keep the simmer moderate; a rolling boil can bash the potatoes into mush.
- Dress potatoes while warm so they soak up the vinaigrette.
- Do not overdress the salad; start with less, then add more to taste.
- Dry the beans well after blanching so water does not thin your dressing.
- Use waxy potatoes like Yukon Gold; starchy russets fall apart in vinaigrette.
- Taste and adjust acid at the end; a tiny splash of vinegar can perk it up right before serving.
- Pack herbs in, but chop them fine so they fold in cleanly instead of clumping.
- If you add anchovy, mince it to a paste so it seasons every bite.
Variations I’ve Tried
- Niçoise-style: add olives, cherry tomatoes, anchovy, and hard-cooked eggs. Keep the Dijon vinaigrette and extra tarragon.
- Dill and smoked salmon: swap tarragon for dill, add flaked smoked salmon, and finish with lemon zest.
- Warm bacon twist: crisp bacon, then whisk a tablespoon or two of warm bacon fat into the vinaigrette and fold in crumbled bacon at the end.
- Mustard swap: use half whole-grain mustard and half smooth Dijon for pops of texture.
- Vinegar play: try sherry vinegar for a rounder profile or Champagne vinegar for a lighter touch.
How to Serve
Serve this salad slightly warm or room temp with roast chicken, grilled salmon, or a simple steak. Pair it with a crisp white like Sauvignon Blanc or a chilled rosé, or pour sparkling water with a lemon wheel if that’s the vibe. Add soft-cooked eggs or oil-packed tuna and call it lunch. A torn baguette happily soaks up every last drop of vinaigrette.
Make-Ahead and Storage
- Vinaigrette: mix it up to 1 week ahead and keep it chilled; shake before using.
- Components: cook potatoes and beans up to 2 days ahead. Store them separately, and toss the potatoes with a spoonful of vinaigrette to keep them from drying.
- Fully dressed salad: keep it in an airtight container in the fridge for up to 3 days. Toss and refresh with a splash of vinegar and a drizzle of olive oil before serving.
- Do not freeze; potatoes and green beans lose texture after thawing.
- To take the chill off, set the salad on the counter for 20 to 30 minutes. You can also microwave a serving for 10 to 15 seconds to loosen the dressing, then toss and serve.

Ingredients
Instructions
- Place the potatoes in a large pot and cover with cold salted water. Bring to a boil, then reduce heat and simmer until just tender when pierced with a knife, 12 to 15 minutes depending on size.
- While the potatoes cook, bring a separate pot of salted water to a boil. Add the green beans and cook until crisp-tender and bright green, about 3 to 4 minutes. Immediately transfer to an ice bath to stop the cooking, then drain well.
- In a large bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, whole-grain mustard (if using), minced shallot, garlic, salt, and pepper until emulsified.
- Drain the potatoes and let them steam-dry for a minute or two. While still warm, add the potatoes to the bowl with the vinaigrette and gently toss to coat.
- Add the drained green beans, parsley, tarragon, and capers (if using). Toss gently until everything is evenly coated and combined. Adjust seasoning with additional salt and pepper to taste.
- Serve warm or at room temperature. The flavors will continue to develop as the salad sits.
