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 stop cooking. Drain again and pat dry.
02 - In a large skillet over medium heat, toast sliced almonds while stirring frequently for 2 to 3 minutes until golden and fragrant. Transfer to a plate and set aside.
03 - Using the same skillet, heat olive oil over medium heat. Add minced garlic and sauté for 1 minute until fragrant without browning.
04 - Add the blanched green beans to the skillet. Toss to coat with olive oil and garlic, sautéing for 3 to 4 minutes until heated through.
05 - Sprinkle lemon zest, lemon juice, salt, and black pepper over the green beans. Toss well and cook for another 1 to 2 minutes to combine flavors.
06 - Transfer green beans to a serving platter, sprinkle toasted almonds on top, and serve immediately.
