Notes & Wine Advice
Serving Suggestions
Serve the pasta salad chilled or at room temperature with crusty bread, grilled vegetables, or a fresh green salad. It is also suitable for picnics and packed lunches. For a larger summer meal, serve it alongside our Cheesy Zucchini Tomato Bake.
Recipe Notes
Cook the pasta until al dente so it retains a pleasant texture after chilling. Pouring the hot pasta water over the zucchini softens it slightly without making it mushy. Dry the basil thoroughly after washing to prevent the pesto from becoming watery.
Variations
Add cherry tomatoes, mozzarella, toasted pine nuts, olives, peas, spinach, or roasted peppers. Whole-wheat or gluten-free pasta can replace regular pasta. Pecorino Romano provides a sharper alternative to Parmesan, while walnuts can replace traditional pine nuts.
Storage
Refrigerate the pasta salad in an airtight container for up to three days. The pasta will absorb some of the pesto during storage, so stir in a little olive oil before serving. Freezing is not recommended because the zucchini and basil may lose their fresh texture.
Wine Advice
A crisp Sauvignon Blanc complements the fresh basil, garlic, and zucchini. A chilled Pinot Grigio is another refreshing choice for this light summer pasta salad.
