Zesty Lemon Arugula Pasta

This lemon arugula pasta salad combines bright citrus flavors with peppery arugula and tender pasta for a refreshing meal perfect for warm weather gatherings. The simple lemon dressing coats each bite with tangy goodness while the walnuts add unexpected crunch and depth.

I first created this pasta salad for a neighborhood potluck when temperatures hit 95 degrees. It disappeared faster than any other dish, and now it's my signature contribution to summer gatherings.

Ingredients

• Pasta: I prefer farfalle or orzo as they catch the dressing beautifully and mix well with the arugula
• Arugula: The peppery bite balances the tangy lemon perfectly, look for bright green leaves without wilting
• Walnuts: Adds essential crunch and healthy fats, toast them lightly to enhance flavor
• Parmesan or Pecorino: Choose freshly grated for best flavor, pecorino offers a sharper profile
• Fresh Lemon: Both juice and zest provide bright acidity and citrus aroma
• Quality Olive Oil: The backbone of the dressing, use your best extra virgin for superior flavor
• Capers: These tiny flavor bombs add briny depth and interest to each bite
• White Balsamic Vinegar: Offers subtle sweetness without discoloring the salad, regular balsamic works too
• Dijon Mustard: Acts as an emulsifier for the dressing while adding complexity
• Fresh Basil: Optional but adds wonderful aromatic notes and color

Step-by-Step Instructions

Cook the Pasta:

Boil pasta 1 minute longer than package directions for al dente. You want it slightly softer for a pasta salad to absorb dressing. After cooking, drain immediately and rinse under cold water until completely cool. This stops the cooking process and removes excess starch that would make your salad gummy.

Create the Dressing:

In a large mixing bowl, whisk together lemon juice, zest, white balsamic vinegar, dijon mustard, and olive oil until emulsified. The mustard helps bind the oil and acid together for a creamy dressing. Then stir in the walnuts, capers and their brine, salt, pepper, and grated cheese. The brine from the capers adds wonderful complexity.

Combine with Pasta:

Add the cooled pasta to the dressing bowl and toss thoroughly. Let it sit for 5 minutes to absorb the flavors. This resting period is crucial for the pasta to take on the bright lemon flavor throughout each piece.

Fold in Greens:

Just before serving, gently fold in the arugula and basil. Adding them last keeps them from wilting and maintains their fresh texture and color. The warmth from the pasta will slightly wilt the greens to the perfect consistency.

Pin it

The addition of capers was actually a happy accident when I was running low on salt one summer evening. Their briny punch elevated the entire dish, and now I consider them essential. My daughter, who typically avoids anything green, actually requests this pasta salad regularly, proof that the right combination can win over even picky eaters.

Make Ahead Magic

This pasta salad actually improves with time, making it ideal for preparation up to 24 hours in advance. Store the dressed pasta separately from the arugula and combine just before serving. The lemon juice and olive oil continue to infuse the pasta, creating a more flavorful result the next day. For picnics or outdoor gatherings, this stability makes it a reliable option that won't spoil quickly.

Creative Variations

Transform this versatile base recipe by adding your favorite proteins or vegetables. Grilled chicken, sliced cherry tomatoes, diced bell peppers, or crumbled feta cheese all complement the lemon dressing beautifully. For a heartier version, add cannellini beans or chickpeas for protein and fiber. You can also swap the arugula for baby spinach or kale; massage the kale with a bit of the dressing to soften it first.

Serving Suggestions

Serve this bright pasta salad alongside grilled fish, chicken, or as a light standalone lunch. For an elegant presentation, pile it high on a white platter and garnish with additional lemon wheels, fresh herbs, and a sprinkle of flaky sea salt. This dish shines at room temperature, making it perfect for buffets where food might sit out for a while. A chilled crisp white wine like Sauvignon Blanc or Pinot Grigio pairs beautifully with the citrus notes.

Frequently Asked Questions

→ Can I prepare this pasta salad ahead of time?

Yes! This pasta salad actually improves with a bit of time in the refrigerator. You can prepare it up to 24 hours in advance, though you may want to add the arugula just before serving to maintain its texture. Let it sit at room temperature for about 15 minutes before serving for the best flavor.

→ What can I substitute for arugula?

Baby spinach, watercress, or a spring mix would all work well as alternatives to arugula. Each will provide a slightly different flavor profile, with watercress offering a similar peppery bite and spinach providing a milder flavor.

→ Is there a nut-free version of this dish?

Absolutely! You can omit the walnuts entirely or substitute with toasted pine nuts, sunflower seeds, or crispy breadcrumbs to maintain the crunchy texture element.

→ What protein would pair well with this pasta salad?

This versatile dish pairs beautifully with grilled chicken, seared salmon, or garlic shrimp. For a vegetarian option, add chickpeas or white beans to make it more substantial. Tuna or sliced hard-boiled eggs would also complement the flavors nicely.

→ Can I use a different type of pasta?

Any medium-sized pasta shape works well in this salad. Beyond farfalle and orzo, try fusilli, penne, rotini, or even small shells. Short pastas with ridges or curves will better capture the dressing throughout the dish.

→ How long will leftovers keep in the refrigerator?

Stored in an airtight container, leftovers will keep well for 3-4 days in the refrigerator. The arugula may wilt slightly, but the flavors will continue to develop. Give it a gentle toss and a drizzle of olive oil before serving again to refresh the texture.
