This Genovese pasta salad brings the bright, herbaceous flavors of classic pesto alla Genovese into a cold, make-ahead dish that’s perfect for picnics, potlucks, and weeknight dinners. The combination of al dente pasta, creamy pesto, tender green beans, and potatoes (a nod to the traditional Genovese pairing) creates a satisfying salad that’s both hearty and refreshing. It’s a versatile recipe that comes together in about 30 minutes and tastes even better after the flavors meld in the fridge.
Ingredients
- 1 lb (450 g) short pasta, such as trofie, fusilli, or farfalle
- 8 oz (225 g) green beans, trimmed and cut into 1-inch pieces
- 8 oz (225 g) baby potatoes, halved or quartered if large
- 1 cup (240 ml) basil pesto, homemade or store-bought
- 2 tablespoons (30 ml) extra-virgin olive oil
- 1 tablespoon (15 ml) lemon juice, freshly squeezed
- 1/4 cup (25 g) grated Parmesan cheese, plus more for serving
- Salt and freshly ground black pepper, to taste
- Fresh basil leaves, for garnish (optional)
Instructions
- Bring a large pot of salted water to a boil. Add the potatoes and cook for 5 minutes, then add the green beans and cook for another 3–4 minutes, until both are just tender. Remove with a slotted spoon and set aside to cool.
- In the same pot of boiling water, cook the pasta according to package directions until al dente. Reserve 1/2 cup of pasta water, then drain the pasta and rinse briefly under cold water to stop the cooking. Drain well.
- In a large mixing bowl, combine the cooled potatoes, green beans, and pasta. Add the pesto, olive oil, lemon juice, and grated Parmesan. Toss gently until everything is well coated. If the salad seems dry, add a splash of the reserved pasta water to loosen it.
- Season with salt and pepper to taste. Cover and refrigerate for at least 30 minutes to let the flavors meld.
- Before serving, give the salad a good stir, taste again for seasoning, and garnish with fresh basil leaves and extra Parmesan if desired.
Tips
- Don’t overcook the pasta: Cook it al dente (firm to the bite) because it will continue to absorb dressing and soften as it sits. Overcooked pasta turns mushy in a cold salad.
- Rinse the pasta: Rinsing under cold water stops the cooking and removes excess starch, which helps the pesto coat the pasta evenly without clumping.
- Adjust the pesto consistency: Pesto thickens when chilled. If the salad seems dry after refrigeration, stir in a little extra olive oil or pasta water before serving.
- Make it ahead: This salad actually tastes better after a few hours in the fridge, so feel free to prepare it a day in advance. Just add the final drizzle of olive oil and fresh basil right before serving.
Serving Suggestions
Serve this Genovese pasta salad as a main dish for a light lunch, or as a side alongside grilled chicken, fish, or a simple green salad. It’s also a great addition to a buffet or picnic spread, as it holds up well at room temperature for a couple of hours. For a heartier meal, top with grilled shrimp or cubed mozzarella.
Variations
- Add protein: Stir in 1 cup of cooked chickpeas, shredded rotisserie chicken, or diced salami for extra substance.
- Swap the vegetables: Use asparagus or broccoli instead of green beans, and skip the potatoes if you prefer a lighter salad. Cherry tomatoes or roasted red peppers add color and sweetness.
- Make it vegan: Use a dairy-free pesto and omit the Parmesan, or replace it with nutritional yeast for a cheesy flavor.
- Try a different pasta: Any short shape works—penne, rigatoni, or shells are all good choices. Gluten-free pasta also works well; just be careful not to overcook it.
Storage and Reheating
Store leftover pasta salad in an airtight container in the refrigerator for up to 4 days. The pasta will absorb some of the pesto, so you may want to add a little olive oil or lemon juice when serving leftovers. This salad is meant to be served cold or at room temperature, so there’s no need to reheat it. If you do prefer it warm, microwave individual portions for 30–60 seconds, but be aware that the texture will change slightly.
Frequently Asked Questions
Can I use fresh pasta instead of dried? Yes, fresh pasta works, but it cooks much faster and can become mushy. Boil it for just 1–2 minutes and rinse immediately with cold water.
What if I don’t have trofie pasta? Trofie is traditional, but any short pasta with nooks and crannies works well. Fusilli, farfalle, or penne are all great choices.
Can I make this salad gluten-free? Absolutely. Use gluten-free pasta and check that your pesto is gluten-free. The rest of the ingredients are naturally gluten-free.
How do I keep the salad from drying out? Always reserve some pasta water before draining. Adding a splash when you toss the salad, and again before serving, keeps the pesto creamy and prevents the pasta from sticking together.
Can I freeze this pasta salad? Freezing is not recommended. The pasta becomes soft and the pesto may separate when thawed, resulting in a mushy, oily texture.
Is this salad good for meal prep? Yes, it’s excellent for meal prep. Portion it into containers and refrigerate for up to 4 days. Add a squeeze of lemon and a drizzle of olive oil to each portion before eating to refresh the flavors.
