The Vegan Pesto Pasta Salad with Cherry Tomatoes is a modern, plant-forward spin on a beloved Italian classic, merging Mediterranean warmth with vibrant summer flavors in a dish thatโs as nourishing as it is beautiful. This recipe pulls its core inspiration from Liguria, a sun-kissed coastal region in northwestern Italy known for two culinary treasures: fragrant, fresh basil and pesto alla Genovese. Traditionally, Ligurian pesto combines basil, garlic, pine nuts, Parmesan cheese, and olive oil, pounded together to create an aromatic, creamy sauce. Here, that essence is honored in spirit while being completely reimagined for a vegan lifestyle.
At the heart of the recipe is the vegan pesto โ lush and bold, rich with basil and enhanced by the nutty savor of nutritional yeast. This ingredient plays a pivotal role in replicating the umami-laden profile of aged cheese without any dairy. A touch of flat-leaf parsley adds dimension and a whisper of greenery, while lemon juice brings brightness and prevents the basil from losing its vivid hue. Toasted pine nuts evoke traditional Italian flavor while adding texture and depth, and a splash of cold water helps emulsify the mixture into a smooth, clinging sauce that coats every twist of pasta just right.
Speaking of pasta, this dish calls for short varieties like fusilli or rotini โ shapes that are ideal for trapping all the nooks and crannies of the pesto. Once cooked and carefully cooled to maintain an al dente bite, the pasta is tossed with seasonal cherry tomatoes that burst with sweetness, a handful of fresh baby arugula for peppery contrast, and crisp cucumber for crunch. Slivers of red onion add a mild sharpness, threaded delicately throughout for balance.
What makes this pasta salad particularly appealing is its versatility. Itโs easily scaled for gatherings โ whether picnics, potlucks, or weekday lunches โ and tastes even better after itโs had time for the flavors to mingle. With no dairy, eggs, or animal products, itโs safe for vegans and dairy-intolerant guests, yet it never skimps on richness or satisfaction. For those seeking customization, the recipe can be made gluten-free with the right pasta swap or bulked up with chickpeas for added protein.
This salad is a celebration of summerโs best produce and a great example of how plant-based cuisine can stand tall beside its traditional counterparts in both taste and integrity. The combination of lemon, herbs, and olive oil transports you to a seaside Italian village with each forkful โ and yet, the simplicity of the method makes it accessible to home cooks of all levels. Whether served slightly chilled from the fridge or at a breezy room temperature, the Vegan Pesto Pasta Salad is more than just a side dish โ itโs summer in a bowl.

Ingredients
For the Vegan Pesto:
- โ cup raw pine nuts

- 2 cup fresh basil leaves packed
- ยฝ cup flat-leaf parsley leaves loosely packed, optional
- 2 tbsp nutritional yeast
- ยฝ tsp kosher salt
- ยผ tsp freshly ground black pepper
- โ cup extra-virgin olive oil
- 2 tbsp fresh lemon juice
- 2 tbsp cold water
For the Salad:
- 1 tbsp kosher salt for pasta water
- 12 oz dried short pasta (fusilli or rotini)
- ยผ cup reserved pasta cooking water cooled
- 2 cup cherry tomatoes halved
- 1 cup English cucumber small-diced
- ยผ cup red onion very thinly sliced
- 2 cup baby arugula loosely packed
- ยผ tsp crushed red pepper flakes optional
Instructions
- Toast the Pine Nuts: Preheat the oven to 325ยฐF / 165ยฐC. Spread the pine nuts on a rimmed sheet pan in a single layer and toast for 6โ8 minutes, shaking once, until pale golden and fragrant. Cool for 5 minutes to protect the pestoโs bright green color.
- Cook and Cool the Pasta: Bring a large pot of water to a rolling boil, then season with the kosher salt. Add the pasta and cook for 10โ11 minutes until al dente. Reserve 1/4 cup pasta cooking water, then drain. Rinse under cool water for 20โ30 seconds to stop cooking, and spread the pasta on a sheet pan to steam-dry for 5 minutes.
- Make the Vegan Pesto: In a food processor, combine cooled toasted pine nuts, garlic, nutritional yeast, kosher salt, and black pepper; pulse 10โ12 times until sandy. Add basil and parsley; pulse to coarsely chop. With the motor running, stream in olive oil and lemon juice, then add the cold water; process 45โ60 seconds until smooth, vivid green, and emulsified. Scrape down the bowl once to ensure an even texture.
- Assemble the Salad: In a large mixing bowl, combine cooled pasta, cherry tomatoes, cucumber, red onion, and arugula. Spoon in about 3/4 of the pesto and toss for 1โ2 minutes until every piece is well coated, loosening with 2โ4 tablespoons of the reserved pasta water as needed for a glossy sheen. Fold in the remaining pesto and sprinkle with red pepper flakes. Taste and adjust seasoning with a pinch more salt or a squeeze of lemon.
- Serve: Let the salad rest for 10 minutes to marry flavors, or refrigerate for 20 minutes for a cooler, firmer bite. Serve slightly chilled or at cool room temperature.
Notes
Chefโs Tips:
- Season your pasta water generously; for this batch, 1 tablespoon salt provides backbone without oversalting the finished dish.
- Steam-drying the pasta on a sheet pan prevents a watery salad and helps the pesto cling.
- Nut-free option: Substitute toasted sunflower seeds or pepitas for the pine nuts.
- Gluten-free: Swap in a sturdy gluten-free short pasta and rinse a few extra seconds for best texture.
- Color insurance: A splash of lemon and a quick chill keep basil bright; avoid overheating the pesto in the processor.
- Make-ahead: Toss with 3/4 of the pesto, chill up to 24 hours, then fold in the remaining pesto just before serving.
- Protein boost: Add a drained 15-oz can of chickpeas for a heartier main.
