Pesto Pasta Salad is a fresh and flavorful dish that’s perfect for warm days or anytime you want a quick, delicious meal. It’s made with al dente pasta, tossed in bright green basil pesto, and combined with juicy cherry tomatoes and crunchy pine nuts. The combination of creamy pesto and the mix of textures makes it a real crowd-pleaser.
I love making pesto pasta salad because it’s so simple yet packed with flavor. One of my favorite things is how easy it is to customize—sometimes I add in fresh mozzarella or grilled chicken to make it a heartier meal. Also, letting the salad chill in the fridge for a bit helps the flavors blend beautifully, so I always make it a little ahead of time.
Whenever I bring pesto pasta salad to a picnic or potluck, it disappears fast. It’s perfect served cold or at room temperature, and it holds up well, so you don’t have to worry about it getting soggy. Plus, it’s a great way to enjoy a tasty dish that feels light but still satisfying.
Key Ingredients & Substitutions
Rotini Pasta: This curly pasta holds pesto sauce well thanks to its spirals. You can swap with fusilli, farfalle, or penne—any pasta with ridges or twists works great.
Basil Pesto: Fresh basil pesto brings vibrant flavor. If you’re short on time, quality store-bought works fine. For dairy-free, use a pesto made without cheese or add nutritional yeast instead.
Cherry Tomatoes: They add juicy sweetness and a pop of color. If unavailable, grape tomatoes or diced regular tomatoes can be used, just drain excess juice to avoid sogginess.
Zucchini: Adds crunch and freshness. You can keep it raw or lightly sauté to soften. Cucumber or bell peppers could be swapped in for a different crisp texture.
Parmesan Cheese: Adds depth and saltiness. For a vegan option, nutritional yeast or a dairy-free cheese alternative is a tasty stand-in.
Pine Nuts: They give a nice crunch and nutty flavor. Toasted almonds or walnuts can be used as a budget-friendly or allergy-friendly choice.
How Do You Get the Pasta Just Right for Salad?
The pasta texture is key in pesto pasta salad—it should be cooked al dente (firm to bite) so it doesn’t turn mushy when mixed with pesto or chilled. Here’s how I do it:
- Follow the package time but check pasta a minute or two earlier by tasting it.
- Once perfectly firm, drain and rinse under cold water to stop cooking and cool it down quickly.
- Drain well to get rid of excess water, or the salad could become watery.
- Toss with a bit of olive oil or pesto right away to keep the pasta from sticking.
These small steps help keep the pasta lively and ready to soak up the pesto without losing its bite. This makes the pasta salad fresh and delicious every time.
Equipment You’ll Need
- Large pot – to boil the pasta evenly and prevent sticking.
- Colander – for draining and rinsing the pasta quickly.
- Large mixing bowl – gives plenty of space to toss all ingredients together without spilling.
- Wooden spoon or spatula – helps mix the salad gently without breaking the pasta.
- Measuring cups and spoons – for accurate pesto and seasoning amounts.
Flavor Variations & Add-Ins
- Add grilled chicken or shrimp for a protein boost that turns this salad into a full meal.
- Stir in fresh mozzarella balls or crumbled feta for creamy, tangy cheese options.
- Mix in roasted red peppers or artichoke hearts for extra color and flavor depth.
- Sprinkle red pepper flakes or a squeeze of lemon juice to add a zesty kick.

This recipe takes about 15 minutes to prepare, including boiling the pasta and mixing everything together. Add at least 30 minutes in the refrigerator to let the flavors meld nicely before serving. So, the total time is roughly 45 minutes with chilling time.
Step-by-Step Instructions:
1. Cooking the Pasta:
Bring a large pot of salted water to boil. Add the rotini pasta and cook according to the package instructions until al dente (firm but cooked). Drain the pasta and rinse it under cold water to stop the cooking process and cool it down. Drain well to avoid watery salad.
2. Preparing the Vegetables:
If you prefer raw zucchini, slice it thinly. Or, lightly sauté the zucchini slices in a bit of olive oil over medium heat until just tender, then let them cool. Halve the cherry tomatoes so they’re ready to toss in.
3. Combining the Salad Ingredients:
In a large mixing bowl, add the cooled pasta, basil pesto, and olive oil if using. Toss well to coat the pasta fully with the pesto. Then gently fold in the halved cherry tomatoes and sliced zucchini.
4. Finishing Touches:
Sprinkle the grated Parmesan cheese and toasted pine nuts over the salad. Season with salt and black pepper to your taste, and add red pepper flakes if you like a little heat. Toss everything gently again to mix.
5. Chilling and Serving:
Transfer the salad to a serving bowl. Garnish with fresh basil leaves for color and extra flavor. Chill in the refrigerator for at least 30 minutes to let the flavors blend. Serve cold or at room temperature, perfect as a light meal or side dish.
Can I Use Frozen Pasta for This Salad?
It’s best to cook fresh pasta for this salad, but if using frozen pasta, make sure to thaw it completely and drain any excess moisture before mixing with pesto to avoid a watery salad.
Can I Make Pesto Pasta Salad Ahead of Time?
Yes! Prepare the salad and refrigerate it for up to 2 days. Just give it a gentle stir before serving, and you might want to add a little extra pesto or olive oil to freshen it up.
What Can I Substitute for Pine Nuts?
If you’re allergic or don’t have pine nuts, toasted almonds, walnuts, or cashews work great and add a similar crunch and nuttiness.
How Should I Store Leftover Pesto Pasta Salad?
Keep leftovers in an airtight container in the fridge for up to 3 days. Serve cold or let it come to room temperature and stir before enjoying again.
