Classic Pesto Pasta Salad - Fresh, Bright, and Ready in Minutes
Ingredients
Method
- Cook the pasta: Bring a large pot of salted water to a boil. Add pasta and cook until al dente according to package directions.You want it firm enough to hold up in the salad.
- Cool the pasta: Drain and rinse briefly under cool water to stop the cooking. Shake off excess water. Toss with a drizzle of olive oil so it doesn’t stick.
- Toast the nuts: In a dry skillet over medium heat, toast pine nuts or walnuts for 3–4 minutes, stirring often, until fragrant.Let cool.
- Make the pesto: In a food processor, pulse basil, toasted nuts, garlic, Parmesan, salt, and pepper. With the motor running, stream in olive oil until smooth but still a little textured. Add lemon juice to taste.Adjust seasoning.
- Prep the veggies: Halve the cherry tomatoes, dice the cucumber, and thinly slice the red onion. If using onion, soak it in cold water for 10 minutes, then drain—this keeps it from overpowering the salad.
- Combine: In a large bowl, mix pasta with 3/4 of the pesto. Fold in tomatoes, cucumber, onion, mozzarella, and greens (if using).If it looks dry, add more pesto or a splash of olive oil.
- Season: Add salt, black pepper, and a pinch of red pepper flakes if you like heat. Squeeze in a bit more lemon for brightness.
- Chill (optional but recommended): Cover and refrigerate for 30–60 minutes to let the flavors mingle. Before serving, stir and adjust seasoning.Top with extra Parmesan and a few basil leaves.
Why This Recipe Works

- Make-ahead friendly: The flavors meld as it sits, so it tastes even better after a few hours in the fridge.
- Customizable: Swap in different veggies, add protein, or use store-bought pesto when you’re short on time.

Storage Instructions
- Refrigeration: Store in an airtight container in the fridge for up to 3 days.
- Refresh before serving: Pasta absorbs pesto as it sits. Stir in a spoonful of olive oil, a splash of lemon juice, or a bit more pesto to loosen it.
- Avoid freezing: Fresh basil and mozzarella don’t freeze well. The texture becomes watery and mushy.
- Meal prep tip: Keep extra pesto on hand to mix in just before eating for the best flavor.
Health Benefits
- Heart-healthy fats: Olive oil and nuts provide monounsaturated fats that support heart health.
- Vitamins and antioxidants: Basil, spinach/arugula, and tomatoes bring vitamins A, C, and K along with plant antioxidants.
- Calcium and protein: Parmesan and mozzarella add calcium and a modest amount of protein.
- Customizable carbs: Use whole wheat or high-protein pasta if you want more fiber and satiety.
- Balanced meal: Add grilled chicken, chickpeas, or tuna for extra protein and a complete lunch.
Common Mistakes to Avoid
- Overcooking the pasta: Soft pasta turns mushy and won’t hold the pesto.Aim for al dente.
- Under-seasoning: Salt the pasta water well and taste as you go. Pesto needs proper seasoning to pop.
- Skipping the acid: Lemon juice balances the richness of the oil and cheese. Don’t skip it.
- Drowning the salad: Add pesto gradually.You can always add more, but you can’t take it out.
- Using watery veggies without draining: Tomatoes and cucumbers can release liquid. Pat them dry if they seem extra juicy.
- Not chilling (when serving cold): A brief chill melds flavors and improves texture.
Variations You Can Try
- Protein boost: Add grilled chicken, shrimp, canned tuna, or white beans.
- Different greens: Swap basil pesto for arugula or spinach pesto, or mix basil with parsley for a milder flavor.
- Cheese swap: Use feta for a briny twist or shaved pecorino for extra bite.
- Veggie mix-ins: Roasted red peppers, olives, artichoke hearts, or sun-dried tomatoes add depth.
- Gluten-free: Use your favorite gluten-free pasta and rinse gently to remove excess starch.
- Nut-free pesto: Replace nuts with toasted sunflower seeds or skip them entirely.
- Creamier style: Stir a spoonful of Greek yogurt into the pesto for a lighter, creamy dressing.
FAQ
Can I use store-bought pesto?
Yes. Choose a high-quality refrigerated pesto for the best flavor.
You may still want to add lemon juice and extra Parmesan to brighten it up.
What pasta shape works best?
Short, ridged shapes like fusilli, rotini, farfalle, or penne grip the pesto well and hold up in the fridge.
How do I keep the basil from turning brown?
Blend the pesto quickly, avoid overheating it, and add a squeeze of lemon. Storing with a thin layer of olive oil on top also helps preserve color.
Can I make it dairy-free?
Yes. Use a dairy-free Parmesan alternative or nutritional yeast in the pesto, and skip the mozzarella or use a plant-based version.
How far ahead can I make this?
You can make it up to 24 hours ahead.
Stir in a little extra olive oil or pesto before serving to refresh the texture.
Do I need to rinse the pasta?
For cold pasta salad, a quick rinse is helpful to stop the cooking and keep the pieces from sticking. Shake well to remove excess water.
What if my pesto tastes bitter?
Balance it with a bit more Parmesan, a pinch of salt, and some lemon juice. Also check your olive oil—some oils are more bitter than others.
Can I serve it warm?
Absolutely.
Toss freshly cooked, warm pasta with pesto and toppings. It becomes a cozy, lightly warmed pasta dish rather than a chilled salad.
