What is Pesto Pasta Salad?

Pesto pasta salad is a chilled or room-temperature salad that combines cooked pasta with vibrant basil pesto, fresh vegetables, cheese, and sometimes protein like grilled chicken or beans. It’s light yet satisfying, and easy to make ahead—ideal for meal prep or outdoor gatherings.

Unlike creamy mayonnaise-based pasta salads, this version leans on olive oil and pesto for a naturally flavorful dressing.

Key Ingredients

Here’s what you’ll typically need to create the perfect pesto pasta salad:

Pasta: Rotini, fusilli, farfalle, or penne—shapes that hold sauce well
Pesto: Homemade or store-bought
Vegetables:
- Cherry tomatoes
- Zucchini or yellow squash
- Baby spinach or arugula
- Red bell peppers
Cheese:
- Mozzarella balls
- Crumbled feta
- Freshly shaved parmesan
Extras:

Pro Tip: Cook your pasta slightly beyond al dente—this helps it absorb the pesto better without turning mushy after refrigeration.
