Ingredients
For the Salad
- 1 1/2 pounds (680 g) baby Yukon Gold or baby red potatoes
- 8 oz (225 g) fresh green beans, trimmed and cut into 2-inch pieces
- 1 can (15 oz / 425 g) black beans, drained and rinsed
- 4 large eggs
- 1/2 small red onion, thinly sliced
- 1/4 cup chopped fresh parsley
- 2 tablespoons chopped fresh chives
For the Creamy Dijon Dressing
- 1/3 cup mayonnaise
- 2 tablespoons Dijon mustard
- 1 tablespoon whole-grain mustard
- 2 tablespoons fresh lemon juice
- 1 tablespoon extra-virgin olive oil
- 1 teaspoon honey
- 1 small garlic clove, finely grated
- 1/2 teaspoon salt
- 1/4 teaspoon freshly ground black pepper
Instructions
1. Cook the Potatoes
Wash the potatoes thoroughly and cut larger potatoes into evenly sized pieces, about 1 1/2 inches each. Small baby potatoes can be halved.
Place the potatoes in a large saucepan and cover with cold water by about 1 inch. Add a generous pinch of salt.
Bring to a boil over medium-high heat, then reduce to a gentle simmer.
Cook for 10–15 minutes, or until the potatoes are tender when pierced with a fork but still hold their shape.
Drain thoroughly and allow them to cool for about 10 minutes.
2. Cook the Green Beans
Bring a medium saucepan of salted water to a boil.
Add the green beans and cook for 3–4 minutes, until bright green and crisp-tender.
Immediately transfer the green beans to a bowl of ice water to stop the cooking process.
Let them cool for 2 minutes, then drain thoroughly and pat dry.
3. Cook the Eggs
Place the eggs in a saucepan and cover with cold water by about 1 inch.
Bring the water to a boil. Once boiling, cover the saucepan, remove it from the heat, and let the eggs stand for 10–12 minutes.
Transfer the eggs immediately to a bowl of ice water and allow them to cool completely.
Peel the eggs and cut each one in half lengthwise.
Set aside until the salad is assembled.
4. Prepare the Black Beans
Drain and rinse the black beans thoroughly under cold running water.
Allow them to drain completely. Pat them gently with paper towels if necessary to remove excess moisture.
5. Make the Creamy Dijon Dressing
In a small bowl, whisk together the mayonnaise, Dijon mustard, whole-grain mustard, lemon juice, olive oil, honey, grated garlic, salt, and black pepper.
Whisk until smooth and creamy.
Taste and adjust the seasoning if necessary.
6. Assemble the Salad
Place the slightly cooled potatoes, green beans, black beans, and red onion in a large mixing bowl.
Add about three-quarters of the Dijon dressing.
Gently toss until all the ingredients are evenly coated, taking care not to break the potatoes.
Add the parsley and chives and gently toss again.
Add additional dressing as needed until the salad reaches the desired consistency.
7. Add the Eggs
Transfer the salad to a large serving bowl.
Arrange the hard-boiled egg halves over the salad.
Finish with additional freshly ground black pepper, parsley, and a small amount of whole-grain mustard if desired.
8. Chill and Serve
For the best flavor, refrigerate the salad for about 30 minutes before serving.
Serve chilled or allow it to stand at room temperature for about 10 minutes before serving.
Tips for the Best Potato and Green Bean Salad
Choose Waxy Potatoes
Baby Yukon Gold and red potatoes hold their shape well after cooking and have a naturally creamy texture.
Don’t Overcook the Potatoes
Cook the potatoes only until fork-tender. Overcooked potatoes can fall apart when mixed with the dressing.
Keep the Green Beans Crisp
Briefly blanching the green beans and transferring them directly to ice water helps preserve their fresh texture and vibrant color.
Drain the Black Beans Well
Excess liquid can thin the dressing and discolor the salad. Rinse and drain the beans thoroughly before adding them.
Dress the Potatoes While Slightly Warm
Slightly warm potatoes absorb some of the dressing, giving the salad more flavor.
Add the Eggs Last
Placing the egg halves on top after tossing keeps them intact and creates a cleaner presentation.
Variations
Lighter Dijon Potato Salad
Replace half of the mayonnaise with plain Greek yogurt for a lighter, tangier dressing.
Herb Potato Salad
Add fresh dill, basil, or tarragon along with the parsley and chives.
Extra-Crunchy Version
Add thinly sliced celery, diced cucumber, or chopped radishes.
Spicy Dijon Salad
Add a pinch of red pepper flakes or a small amount of hot sauce to the dressing.
No-Mayonnaise Version
Replace the mayonnaise with additional olive oil and Dijon mustard for a lighter vinaigrette-style salad.
What to Serve with Potato & Green Bean Salad
This salad pairs well with grilled chicken, roasted chicken, baked salmon, grilled steak, sandwiches, burgers, or other barbecue favorites. It can also be served on its own as a satisfying light lunch.
Storage
Store leftover salad in an airtight container in the refrigerator for up to 3 days.
For the best presentation, store the hard-boiled egg halves separately and add them before serving.
Freezing is not recommended because potatoes, green beans, eggs, and creamy dressing can develop undesirable textures after thawing.
