Ingredient Notes and Substitutions:

  • Green Beans: You’ll need approximately two pounds. Young, tender green beans are preferable but they can be pricey.
  • Radishes: I used regular red radishes but any variety will work.
  • Shallots: Shallots are a member of the onion family and are used extensively in French cooking. They grow in clusters (heads) similar to garlic but without the quantity. They have a mild oniony flavor with a hint of garlic.
  • Olive Oil: Use a good quality extra-virgin olive oil but it doesn’t have to be the best.
  • Capers: Capers are the green, unripened flower buds of the caper bush. You can find them in the pickled products section.
  • Dijon Mustard: Use a good Dijon mustard. I’ve tried numerous brands of Dijon mustard and you can’t go wrong with Grey Poupon which is widely available. Maille is also good but it’s pricey. You can also use whole-grain mustard if you prefer.

Step-By-Step Instructions:

  • Gather and prep all the ingredients.
  • Whisk the vinaigrette together in a small bowl and let that sit while blanching the green beans so the flavors have a chance to marry.

  • Prepare an ice bath in a large bowl. (An ice bath is a bowl of ice water.)
  • Bring a large pot of generously salted water to a boil. I usually use at least 2 tablespoons of salt in a large pot of boiling salted water so the green beans get seasoned. However, if you’re salt-sensitive, leave it out.
  • Drop the green beans into the boiling water. Let the water return to a boil (covering it will help it come back to a boil sooner) then cook for 4-5 minutes. The beans should be crisp-tender (try one) and still bright green.
  • Scoop the beans out with a sieve and immediately drop them into the cold water ice bath to “shock” them and set the color.

  • Let the beans cool completely then drain well and blot them dry with paper towels. (You don’t want them dripping wet; excess water will water down the vinaigrette.)
  • Place in a serving bowl with the sliced radishes.

Chef Tips and Tricks:

  • Let’s face it. Trimming green beans is a chore. You can buy bagged, trimmed green beans, but I find it necessary to look each one over anyway as stems can get missed. Here are my tips:
    • Starting with the stem end first and working with a handful or so at a time, line the beans up using the edge of your knife or your hand.
    • With one motion, cut all the tips off at once.
    • Repeat with the other side if desired. Turn the beans around, line up the tips again and trim off the other side. It’s not necessary to trim the bottom tip if you don’t want to; it’s completely edible and it’s often done for aesthetic purposes only.
    • Cut into desired lengths. In this salad recipe, two inches is a good length.

Frequently Asked Questions:

Can you eat raw green beans?

It’s best to avoid raw green beans because of their lectin content which can cause digestive issues. Cooking neutralizes the lectins but also improves their taste, digestibility and antioxidant content.

What is blanching vegetables?

Blanching is a process where vegetables are boiled in water (often salted) and then cooled quickly in a large quantity of ice-cold water (60 degrees Fahrenheit or below) to stop the cooking process. It’s always necessary to blanch vegetables you intend to freeze because it stops enzymes that cause loss of flavor, color and texture. Here’s more information on blanching from Better Homes and Gardens.

Can I make green bean salad ahead of time?

You can get the salad prepped and then all you have to do when ready to serve is combine the green bean salad. Because there is an acid in the dressing, it will cause the beans to turn bland, army green. You can blanch the green beans and make the dressing 1-2 days ahead of time. Refrigerate until needed. Slice the radishes just before serving.
