01 - Bring a large pot of salted water to a boil. Add green beans and cook for 3 to 4 minutes until crisp-tender and bright green.
02 - Drain green beans and immediately plunge into a bowl of ice water to stop the cooking process. Drain again and pat dry.
03 - In a large bowl, whisk together olive oil, lemon zest, lemon juice, minced garlic, sea salt, and black pepper until combined.
04 - Add the green beans to the bowl and toss thoroughly to coat them evenly with the lemon dressing.
05 - Transfer the dressed green beans to a serving platter. Sprinkle with toasted sliced almonds and chopped parsley if desired. Serve immediately or at room temperature.
