Ingredients
The magic of this salad lies in the balance between the mellow potatoes and the bold pesto. We start with waxy baby potatoes that hold their shape after boiling, then coat them in a sauce built from fresh basil, toasted pine nuts, garlic, and a generous handful of Parmesan. A splash of lemon juice lifts the richness, while a pinch of sea salt and cracked black pepper brings everything into harmony. The final garnish of extra pine nuts adds crunch, and a drizzle of extra‑virgin olive oil gives a silky finish.
Main Ingredients
- 1 ½ lb (≈ 700 g) baby potatoes, halved
- ½ cup cherry tomatoes, quartered (optional)
- ¼ cup red onion, finely diced
Pesto Sauce
- 2 cups fresh basil leaves, packed
- ¼ cup pine nuts, lightly toasted
- 2 cloves garlic, minced
- ½ cup grated Parmesan cheese
- ⅓ cup extra‑virgin olive oil
- 1 tablespoon fresh lemon juice
Seasonings & Garnish
- Sea salt, to taste
- Freshly cracked black pepper, to taste
- Extra grated Parmesan, for serving
- Additional toasted pine nuts, for garnish
Each component plays a crucial role: the potatoes provide a creamy canvas, the basil‑pesto delivers herbaceous brightness, and the cheese adds umami depth. The lemon juice cuts through the richness, while the pine nuts contribute a buttery crunch that keeps every forkful interesting. Together, they create a balanced, crowd‑pleasing side that can stand on its own or complement a main course.
Step-by-Step Instructions
Preparing the Potatoes
Place the halved potatoes in a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil over medium‑high heat, then reduce to a gentle simmer. Cook for 10‑12 minutes, or until the potatoes are fork‑tender but still hold their shape. Drain and spread on a baking sheet to steam‑dry for 5 minutes; this step prevents sogginess when the pesto is added.
Making the Pesto
While the potatoes rest, combine the basil, toasted pine nuts, minced garlic, and Parmesan in a food processor. Pulse until coarsely chopped. With the processor running, slowly drizzle in the olive oil until the mixture forms a smooth, glossy sauce. Finish with a tablespoon of fresh lemon juice, then season with sea salt and cracked pepper to taste. The pesto should be bright green and aromatic.
Tossing & Finishing
- Combine potatoes and aromatics. Transfer the warm potatoes to a large mixing bowl. Add the diced red onion and optional cherry tomatoes. The residual heat helps the vegetables release a subtle sweetness.
- Coat with pesto. Pour the freshly made pesto over the potatoes. Gently toss with a wooden spoon or spatula until every piece is evenly coated. The sauce should cling lightly, giving each bite a burst of herb flavor.
- Adjust seasoning. Taste the salad and add a pinch more salt, pepper, or lemon juice if needed. The balance of salty, bright, and nutty flavors is key to a memorable dish.
- Garnish and serve. Sprinkle extra grated Parmesan and toasted pine nuts on top. For a warm presentation, serve immediately; for a chilled version, refrigerate for 30 minutes before serving.
Tips & Tricks
Perfecting the Recipe
Use waxy potatoes. Varieties like Yukon Gold or red‑skin potatoes hold their shape better after boiling, preventing a mushy salad.
Steam‑dry potatoes. Letting boiled potatoes sit uncovered for a few minutes removes excess moisture, allowing the pesto to cling rather than slide off.
Flavor Enhancements
Add a handful of arugula leaves just before serving for peppery contrast, or drizzle a teaspoon of truffle oil for an indulgent twist. A pinch of red‑pepper flakes introduces subtle heat without masking the herbaceous notes.
Common Mistakes to Avoid
Don’t over‑process the pesto; a slightly coarse texture keeps the sauce lively. Also, avoid adding the pesto while the potatoes are still steaming hot, as the heat can wilt the basil and dull its fresh flavor.
Pro Tips
Toast pine nuts yourself. A quick 2‑minute toast in a dry skillet brings out a richer, nuttier flavor than store‑bought pre‑toasted nuts.
Reserve a spoonful of pasta water. If the pesto looks too thick, whisk in a tablespoon of the potato‑cooking water; the starch helps bind the sauce to the potatoes.
Season in layers. Lightly salt the potatoes before boiling, then adjust the final seasoning after tossing with pesto for a perfectly balanced finish.
Variations
Ingredient Swaps
Swap basil for spinach or arugula for a milder pesto, or replace pine nuts with walnuts or almonds for a different nutty profile. For a dairy‑free version, use nutritional yeast instead of Parmesan and a splash of plant‑based milk to keep the sauce creamy.
Dietary Adjustments
Make it gluten‑free by ensuring all packaged ingredients are certified gluten‑free. For vegans, substitute the cheese with a vegan Parmesan and use toasted pumpkin seeds instead of pine nuts. Low‑carb eaters can halve the potato portion and bulk the salad with cauliflower florets.
Serving Suggestions
Pair this salad with grilled chicken, salmon, or a hearty bean stew for a complete meal. It also shines alongside a crisp green salad, crusty sourdough, or as a topping for baked sweet potatoes.
Storage Info
Leftover Storage
Allow the salad to cool completely, then transfer it to an airtight container. Store in the refrigerator for up to 4 days. For longer keeping, portion into freezer‑safe bags, squeeze out excess air, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat gently in a 350°F (175°C) oven, covered with foil, for 12‑15 minutes until warmed through. Alternatively, stir the leftovers in a skillet over low heat, adding a splash of broth or water to revive the pesto’s silkiness. Avoid high heat, which can cause the basil to turn bitter.
