Why You Should Make These Green Beans

About as fancy as I get when making vegetables is roasting them with some olive oil and dusting with Parmesan. Or adding some garlic and lemon zest to a saute. It was time to up my game a bit and these mustardy haricots vert sure hit the spot!

  • Just a few little tweaks make these beans perfect for the holidays or when you want a slightly fancier dish without a lot of effort.
  • Haricots verts are readily available, either frozen or in the produce section.
  • This is a super easy recipe. Cook and cool the green beans and toss them with a flavorful mustard vinaigrette filled with briny kalamata olives. As Ina would say, how easy is that?

How to Make these Mediterranean Green Beans

I served these amped-up green beans with olives over the Christmas holidays. I was unsure what the picky hubby would think as green olives with pimento are more his style. But he was an instant fan. A lovely side dish that pairs well with loads of different entrees, these mustardy haricots verts also would also be ideal picnic fare as they taste terrific at room temperature.

  • Buy the freshest green beans possible. Look for blemishes, bulges, or other signs that they’re old. There should not be bulges, but instead the beans should be thin without large seeds. They should also snap when bent.
  • Frozen, defrosted beans are wonderful when fresh beans aren’t available or look past their prime.
  • Make the simple vinaigrette, then steam or boil the beans just until they are tender.
  • Plunge into ice water to stop the cooking process. You do not want your beans to keep cooking, turning from bright green to a darker greenish-gray color.
  • Make sure to dry off your beans if you gave them an ice bath so the water doesn’t dilute the dressing.
  • Serve at room temperature or you can gently warm being careful not to overcook.

I love that this is not your ordinary side dish. Something a little different, a little special. When you have a crazy busy holiday, these mustardy haricots verts are a lovely option for your menu. But also great for a weeknight to jazz things up a bit! Keep this lovely recipe on your radar!
