Step‑by‑Step Instructions for Arugula Pesto Potato Salad
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high heat will create a beautiful golden color on the potatoes. Make sure your oven is fully preheated before placing the tray inside for optimal roasting.
Step 2: Prepare and Roast the Potatoes
In a large half-sheet pan, toss the peewee or fingerling potatoes with a generous drizzle of olive oil, kosher salt, and freshly cracked black pepper. Arrange them cut-side down and roast in the preheated oven for 15 minutes until they begin to brown slightly and become tender.
Step 3: Add Spring Onions
After the initial potato roasting time, remove the pan from the oven carefully, and add the sliced red spring onions on top of the potatoes. Return the pan to the oven, roasting for an additional 25 minutes, or until both the potatoes and onions are golden brown and tender to the bite.
Step 4: Cool the Potatoes
Once your potatoes and spring onions are perfectly roasted, remove them from the oven and allow them to cool for about 10 minutes. This brief cooling period will help maintain their structure when combined with the other fresh ingredients in the Arugula Pesto Potato Salad.
Step 5: Combine Fresh Ingredients
In a large mixing bowl, combine the fresh arugula, crunchy radishes, and the green tops of the roasted spring onions. Gently toss to mix these bright ingredients, which will provide a flavorful contrast to the creamy pesto you’re about to make.
Step 6: Make the Pesto
In a food processor, pulse together the arugula, basil, chives (if using), garlic, pine nuts, and Pecorino Romano cheese until they’re finely chopped. Gradually stir in lemon zest, lemon juice, and a drizzle of olive oil, seasoning with a pinch of kosher salt and cracked black pepper to taste.
Step 7: Assemble the Salad
Now it’s time for the magic! Add the warm roasted potatoes and spring onions to the bowl with the fresh salad ingredients. Spoon in the vibrant arugula pesto, adding it to taste, and gently toss everything together until each bite is coated in that delightful pesto.
Step 8: Serve and Enjoy
Finally, serve your Arugula Pesto Potato Salad warm or at room temperature for the best flavor. Spritz a bit more lemon juice or add a sprinkle of extra black pepper before serving to brighten the dish. Enjoy this seasonal delight alongside your favorite main course!

Make Ahead Options
These Arugula Pesto Potato Salad components are a lifesaver for busy home cooks! You can prepare the arugula basil pesto up to 3 days in advance; simply store it in an airtight container in the refrigerator to maintain its vibrant flavor. Additionally, roast the potatoes and spring onions up to 24 hours ahead of time. After roasting, let the veggies cool completely before refrigerating them to preserve their texture. When you’re ready to serve, combine the fresh ingredients—arugula and radishes—and add the pesto with the roasted potatoes right before plating. This way, you’ll enjoy a refreshing and time-saving dish that tastes just as delicious as if it were made fresh!
Expert Tips for Arugula Pesto Potato Salad
-
Choose the Right Potatoes: Opt for peewee or fingerling potatoes for a delightful texture. Avoid larger potatoes, as they may become mushy in comparison.
-
Don’t Overcook the Onions: Add spring onions during the last roasting phase to maintain their sweet flavor and crunch. Overcooking can lead to a soggy texture.
-
Adjust the Pesto: If the arugula pesto is too thick, add a bit more olive oil to reach your desired consistency. Taste and tweak with lemon juice for brightness!
-
Serve Warm or Room Temperature: Enjoy the salad warm or at room temperature for the best flavor experience. Chilling can dull the vibrant fresh flavors of the arugula pesto potato salad.
-
Keep It Fresh: If making ahead, prepare the pesto and store separately. Combine with fresh ingredients just before serving to keep the salad crisp and delicious!
