Roasted Potato Salad with Mustard and Fennel Seed
2 ½ pounds small new potatoes, cut into 1-inch pieces if necessary
5 tablespoons extra-virgin olive oil
1/3 cup Dijon mustard
1 teaspoon cider vinegar
1 teaspoon Worcestershire sauce
1 tablespoon finely chopped shallot
1 small garlic clove, finely chopped
½ teaspoon fennel seeds, ground fine in a spice grinder
Freshly ground black pepper
2 tablespoons finely chopped fresh parsley leaves
1. Preheat the oven to 425 degrees. Line a baking sheet with parchment paper or nonstick aluminum foil. Toss the potatoes with 1 tablespoon of olive oil and sprinkle with salt. Roast until softened and golden, about 35 minutes.
2. While the potatoes are roasting, whisk together the mustard, remaining 3 tablespoons olive oil, vinegar, Worcestershire sauce, shallot, garlic, ground fennel seeds, ½ teaspoon salt, and ground black pepper to taste.
3. Transfer the potatoes to a bowl and let cool slightly. Toss with the dressing and adjust the seasonings. Stir in the parsley. Serve warm or refrigerate for up to 1 day and serve chilled.
