01 - Bring a large pot of salted water to a boil. Add green beans and blanch for 2 to 3 minutes until bright green and just tender. Drain and immediately plunge into ice water to halt cooking. Drain again and pat dry.
02 - In a large skillet over medium heat, toast sliced almonds, stirring frequently for 2 to 3 minutes until golden and fragrant. Transfer to a plate and set aside.
03 - Heat olive oil in the same skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant without browning.
04 - Add blanched green beans to the skillet and toss to coat with garlic and olive oil. Sauté for 3 to 4 minutes until thoroughly heated.
05 - Sprinkle lemon zest, lemon juice, salt, and black pepper over the beans. Toss well to combine and cook for an additional 1 to 2 minutes.
06 - Transfer the green beans to a serving dish, sprinkle with toasted almonds, and serve immediately.
