Mustardy Haricots Verts Recipe

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!

But these little tweaks are perfect for holidays or when you want a slightly fancier side dish without a lot of effort. For these green beans, I steamed frozen haricots verts and tossed them with a mustard vinaigrette filled with briny kalamata olives. As Ina would say, how easy is that???

Mediterranean Green Beans with Olives and Mustard

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.

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!
