Let’s Talk Pesto

Use high-quality or homemade pesto for a flavorful salad; try my Pesto Recipe or buy fresh basil pesto like Rana’s® Basil Pesto from the grocery’s refrigerated section.

What To Do With Leftover Pesto

Fresh pesto adds flavor to many dishes and keeps well in the fridge for multiple meals. Beyond pasta, use it in sandwiches, pizzas, soups, and favorites like Creamy Pesto Pasta, Pesto Rice, Pesto Pizza, and Pesto Chicken Tortellini.

Pesto Pasta Salad Dressing Ingredients

  • Fresh Pesto: Key ingredient for flavor.
  • Mayonnaise: Full-fat preferred for flavor; light/fat-free will work.
  • Sour Cream: Light/fat-free versions work too.
  • Dijon Mustard: Adds savory depth; don’t use yellow mustard.
  • Lemon Juice: Freshly squeezed for brightness and balance.

How To Make Pesto Pasta Salad (Tips)

  1. Cook Pasta Al Dente: Follow package instructions and test for doneness to avoid mushiness.
  2. Salt Pasta Water: Salt cooking water for flavorful pasta from the inside out.
  3. Cool Pasta First: Refrigerate pasta until cool to keep veggies crisp and prevent dressing becoming oily.
  4. Choose Quality Pesto: High-quality pesto elevates the flavor.
  5. Season to Taste: Adjust with salt, pepper, lemon juice, or honey as needed.

Pesto Pasta Salad

Pesto Pasta Salad with rotini, cherry tomatoes, cucumbers, mozzarella, and a delicious basil-pesto dressing is super easy to make and a guaranteed crowd-pleaser!
Prep Time: 25 minutes
Pasta Cooling Time: 30 minutes
Total Time: 55 minutes
Servings: 8 servings

Ingredients 
 

  • 1 lb (16 oz) rotini pasta (Note 1)
  • Fine sea salt & pepper
  • 1ยฝ cups cherry tomatoes, halved
  • 1ยฝ cups cucumbers, cut into half moons
  • 8 oz mozzarella pearls
  • Optional: fresh basil

Dressing

  • 1 cup fresh basil-pesto (Note 2)
  • ยผ cup full-fat mayo
  • 3 tbsp sour cream (light is great)
  • 1 tsp Dijon mustard
  • 1 tablespoon fresh lemon juice

Instructions 

  • PASTA: Bring a large pot of water (12 cups) to a boil. Add 1 tablespoon of salt and return to a boil. Add pasta and cook according to package directions for al dente. Drain the pasta, but don't rinse it under water. Toss it a few times as it cools, then put it in the fridge to finish cooling.
  • DRESSING: Meanwhile, combine the dressing ingredients in a medium-sized bowl. Season to taste, I add ยฝ tsp salt & ยผ tsp pepper, but it will depend on how salty your pesto is!
  • ASSEMBLE: Once the pasta is completely cooled, add the cherry tomatoes, cucumbers, and mozzarella pearls to the bowl. Use a spatula to scrape every bit of dressing on top, and then gently stir to combine. If desired, rip some basil leaves and stir them through. Taste the salad and adjust the flavors as needed, adding extra salt, pepper, or lemon juice.
  • ENJOY: Enjoy the pasta salad on the same day it's made, but it will last up to three days in the fridge. Toss well before serving.

Recipe Notes

Note 1: Rotini Pasta is ideal for salads due to its shape; high-quality brands like Barilla recommended.
Note 2: Use high-quality Pesto for best flavor; my homemade pesto recipe is great, or save time with store-bought, fresh basil pesto like Rana'sยฎ Basil Pesto, found near refrigerated pasta and cheese.
