Step‑by‑Step Instructions for Tangy Roasted Potato Salad
Step 1: Potato Prep
Begin by cutting your Yukon Gold or Russet potatoes into wedges. Place them in a large pot of cold salted water, ensuring the water covers them fully. Bring the pot to a boil over medium-high heat and let it simmer for about 20 minutes, or until the potatoes are fork-tender. Drain the potatoes and set them aside to cool slightly.
Step 2: Oven Roasting
Preheat your oven to 430°F (220°C). In a mixing bowl, drizzle the drained potatoes with olive oil and season generously with salt and pepper. Spread the potatoes evenly on a lined baking sheet, ensuring they are in a single layer. Roast for approximately 40 minutes, turning them halfway through, until they are golden brown and crispy on the outside.
Step 3: Veggie Sauté
While the potatoes are roasting, prepare the vegetables. In a skillet, heat a tablespoon of olive oil over medium-high heat. Add the sliced red onion and sauté for about 5 minutes, or until they soften and become slightly translucent. Once done, set the red onions aside and use the same skillet to cook the trimmed green beans for another 5 minutes, until they are vibrant and tender-crisp.
Step 4: Vinaigrette Preparation
In a separate bowl, whisk together the apple cider vinegar, egg yolks, wholegrain mustard, dried Italian herbs, sugar, and lemon juice. Gradually stream in the remaining olive oil while continuously whisking until the vinaigrette is smooth and emulsified. This tangy dressing will beautifully complement your roasted potato salad. Cover and refrigerate until you’re ready to serve.
Step 5: Combine Ingredients
In a large mixing bowl, combine the roasted potatoes with the sautéed red onions and green beans. Add the finely chopped fresh dill for a burst of flavor. Drizzle the tangy vinaigrette over the salad, and using a spatula or spoon, gently toss everything together until evenly coated. Serve warm to enjoy the delightful flavors of your Tangy Roasted Potato Salad!

How to Store and Freeze Roasted Potato Salad
Fridge: Store any leftover roasted potato salad in an airtight container in the refrigerator for up to 3 days. Before serving, give it a gentle toss to revive the flavors.
Freezer: While it’s best enjoyed fresh, you can freeze the salad without vinaigrette for up to 2 months. Thaw in the fridge overnight and reheat gently to restore some of the original texture before adding fresh vinaigrette.
Reheating: Reheat the potatoes in the oven at 350°F (175°C) for about 15 minutes to regain crispiness. Avoid microwaving as it may make the potatoes soggy.
Make Ahead Options
These Tangy Roasted Potato Salad ingredients are perfect for meal prep enthusiasts! You can prepare the vinaigrette up to 3 days in advance; simply whisk together the vinaigrette ingredients and refrigerate until ready to serve. Additionally, you can roast the potatoes and cook the green beans up to 24 hours before serving. Just be sure to let the potatoes cool completely before refrigerating to maintain their crispness. When you’re ready to serve, reheat the potatoes in the oven to regain that crispy texture, then toss everything together with the sautéed onions and fresh dill. This way, you can whip up a delicious side dish with minimal effort on busy weeknights!
