Mustard & Herb Roasted Fingerling Potatoes

Over the 4th of July this year I was in Italy – Sicily to be exact. I can’t wait to share some photos and stories from the trip in another post, but first, I have to admit something. I really missed not being home for the 4th! Specifically, I missed the food. I know how this sounds, and I wouldn’t trade that week in Sicily for anything, but in the midst of all the pasta and pizza, I found myself longing for the familiar smell of a charcoal grill going and everyone crowding around a big buffet of classic American summer dishes.

What does all this have to do with Mustard & Herb Roasted Fingerlings? Well, this recipe was particularly on my mind because it’s my favorite way to cook potatoes for a barbecue or summer dinner party, and I realized that as often as I make these, I hadn’t put the recipe online yet. So here they are- before any more precious summer weekends go by!

The recipe is so simple, and it goes well with almost any grilled meat or fish. But most importantly, people go crazy for these potatoes. The crispy exterior and creamy inside of roasted fingerlings is heaven on its own, but toss the hot potatoes with fresh dill, parsley, and a little bit of vinegar and you may never eat potatoes any other way again. Seriously.

Besides being a crowd pleaser, these potatoes are a perfect dinner party or cookout dish for a few reasons. Like the carrots I posted recently, they are equally delicious served hot, warm or at room temperature, so you can make them in advance without having to time them with the steak, chicken, etc. Second, while the recipe only serves four as written, it’s really easy to double- all you need is an extra sheet pan. And finally, I love this recipe because except for one friend I have who hates dill (not naming names, Julie) everyone can eat it. It’s vegan, gluten-free, and dairy free, and the cook’s favorite, stress-free! Make ’em this weekend and let me know what you think!!

  1. If you make this ahead of time, do you wait to toss the potatoes with the oil/vinegar/herbs until ready to serve, or do you add the sauce and let it sit to room temp?

    many thanks.

    1. Regardless of when I’m serving, I toss the roasted potatoes with the herbs/vinegar/oil right after they come out of the oven so they absorb the dressing!
