This vibrant Cold Green Bean Salad (Italian-Style) with cannellini beans, tomatoes, and lemon vinaigrette is fresh and bold! The perfect summer salad is ready for your next potluck- in 20 minutes!
Blanch the Green Beans: Bring a large pot of generously salted water to a boil. Add the green beans and cook 3–5 minutes until crisp-tender and vibrant green. Do not overcook.
Shock in Ice Water: Immediately transfer beans to a bowl of ice water to stop the cooking. Let cool completely, then drain and pat dry.
Make the Vinaigrette: In a small bowl or jar, whisk together lemon zest, lemon juice, garlic, Dijon, Italian seasoning, salt, and pepper. Slowly drizzle in the olive oil while whisking until emulsified and glossy.
Assemble the Salad: In a large bowl, combine green beans, cannellini beans, tomatoes, and basil. Pour dressing over and toss gently to coat.
Finish & Serve: Transfer to a serving platter. Top with toasted nuts and shaved Parmigiano. Taste and adjust salt and lemon if needed. Serve chilled or at cool room temperature.
Notes
Salt the blanching water well — it seasons the beans from within.
Do not skip the ice bath — this locks in that bright green color.
Dry the beans thoroughly before dressing to prevent dilution.
Dress the salad 20–30 minutes before serving so flavors marry.
Use real Parmigiano Reggiano — it makes a noticeable difference.
