Delicious Arugula Pesto Potato Salad ready to serve in a bowl.

I make this Arugula Pesto Potato Salad when I want a bright and vibrant dish that still feels substantial enough for a weeknight meal. The crispy roasted potatoes combined with a herbaceous pesto create a harmonious blend of textures and flavors that make each bite interesting. This salad is a feast for the senses, showcasing the creamy, herby pesto against tender potatoes, making it perfect for a quick weeknight gather instead of a monotonous side dish.

Why This Arugula Pesto Potato Salad Works

The technique of roasting the potatoes achieves a crispy exterior while ensuring a fluffy interior, enhancing their appeal. Using fresh arugula, packed with flavor, provides a peppery undertone that brightens the entire dish and balances the richness of the pesto. The finished salad feels refreshing yet filling, perfect for accompanying grilled meats or enjoying on its own.

Ingredients

2 lbs “pee wee” potatoes, halved
Olive oil
Kosher salt
Freshly cracked black pepper
3 red spring onions, thinly sliced
2 cups packed arugula
6 radishes, thinly shaved on a mandolin
1 cup packed basil leaves
1 small handful chives
2 garlic cloves, chopped
⅓ cup toasted pine nuts
⅓ cup grated pecorino romano cheese
½ tsp lemon zest
2 tbsp lemon juice
1 tbsp honey
¾ cup extra virgin olive oil

Gathering quality ingredients sets the foundation for a successful salad, and the dish appreciates a drizzle of olive oil for roasting and dressing.

How To Make It

Preheat the oven to 425°F. This temperature ensures the potatoes roast properly, allowing them to crisp up nicely.
Place the potatoes on a half sheet pan. Drizzle them generously with olive oil and season with salt and pepper; toss to coat.
Spread the potatoes into one even layer, cut-side down. Roast for 15 minutes.
Arrange slices of spring onion over the potatoes and continue to roast for an additional 25 minutes, until the potatoes are golden brown and tender. The spring onions will soften and add a mild sweetness.
Let the roasted mixture cool on the sheet pan for about 10 minutes.
In a large salad bowl, combine the arugula, radishes, and remaining green spring onion stems.
For the pesto, blend arugula, basil, chives, garlic, pine nuts, pecorino romano cheese, lemon zest, lemon juice, and honey in a food processor until finely chopped. Gradually add ¾ cup olive oil while blending; this emulsification creates a lush pesto.
Add the cooled potatoes and onions to the salad bowl. Toss with enough pesto to coat the mixture to your liking, reserving any extra pesto for future use.
Serve the potato salad warm or at room temperature, finishing with an extra crack of black pepper for flavor.

This salad holds up beautifully, making it ideal for weeknight dinners or casual gatherings.

Quick Substitutions

“Pee wee” potatoes → Baby or fingerling potatoes: Both alternatives will hold their shape well and provide a similar texture.
Olive oil → Avocado oil: Avocado oil has a higher smoke point while adding a mild flavor.
Radishes → Sliced cucumbers: Use cucumbers for a refreshing crunch, though they will yield more water.
Pecorino Romano cheese → Parmesan cheese: This swap gives a slightly nuttier taste without losing creaminess.
Honey → Maple syrup: For a vegan option, maple syrup can substitute honey, imparting a subtle sweetness.

These substitutions allow you to customize the salad while maintaining its fresh characteristics.

Tips Before You Start

One key to this recipe is ensuring the potatoes are cut uniformly to guarantee even cooking. If you find your potatoes are not crisping up, they may be crowded on the baking sheet; give them enough space for air circulation. For added flavor, consider experimenting with different herbs in the pesto, like mint or parsley. Personally, I’ve also enjoyed a sprinkle of red pepper flakes for a spicy kick, especially during the cooler months.

Common Mistakes to Avoid

Crowding the baking sheet: If the potatoes are too close together, they will steam instead of roast. Instead, ensure they are in one layer with space between.
Forgetting to cool the roasted potatoes: Adding piping hot potatoes to the salad can cause the arugula to wilt, detracting from the overall texture. Let them cool before mixing.
Using stale nuts: Pine nuts can go rancid quickly; opt for fresh ones to enhance flavor and crunch.

By avoiding these pitfalls, you’ll ensure a more enjoyable result.

Serving Ideas

Grilled chicken: The light, zesty flavors complement the charred richness of grilled poultry.
Seared salmon: The earthiness of the potatoes pairs nicely with the fish’s richness.
Roasted vegetables: On the side, it adds a colorful, healthy contrast with something hearty.
Crusty bread: Adding a slice alongside offers a nice textural contrast, perfect for mopping up any extra pesto.
Crumbled feta: A sprinkle of this cheese on top can enhance the creaminess and flavor of the dish.

These pairings will enrich your dining experience.

Storage and Reheating

Fridge time: The salad will last in the refrigerator for up to 3 days.
Freezing: Not recommended due to the potato’s texture change.
Reheating: Warm the salad gently in a skillet over low heat, adding a splash of water to prevent sticking.
Texture change: Expect the arugula to wilt after a day, losing some freshness but the flavors will still remain.

Plan to enjoy the salad fresh, as it tastes best on the first day.

Leftover Ideas

Transform leftovers into a robust breakfast by adding a poached egg on top for additional protein. Another option is to reheat the salad and toss it with cooked quinoa for a satisfied lunch option. Lastly, consider making a frittata mixing the salad ingredients with whisked eggs for a creative use of leftovers.
