When green beans are in season, it’s also the time to find truly sweet-fleshed onions, such as Vidalia and Walla Walla. This vinaigrette brings out the sweetness of the onions and makes the best of fresh summer beans.


  • 2 pounds fresh green beans
  • 3 tablespoons olive oil
  • 2 tablespoons white-wine vinegar
  • 1 tablespoon Dijon mustard
  • ½ large sweet onion, such as Vidalia or Walla Walla, finely chopped
  • Salt and pepper, to taste

    How to make it  

  • 1

    Remove the top and the tail of the green beans, and slice in half diagonally.

  • 2

    Bring a large pot of salted water to a boil and add the green beans. Cook for about 8 minutes, or until just tender.

  • 3

    Meanwhile, in a medium bowl, stir together the oil, vinegar, and mustard. Add the onions and season with a little salt and pepper.

  • 4

    Drain the beans well. Pour the vinaigrette over the hot beans and marinate for at least 10 minutes before serving. Serve warm or at room temperature.
