01 - Bring a large pot of salted water to a boil. Add green beans and cook for 2 to 3 minutes until bright green and crisp-tender. Drain and immediately transfer to a bowl of ice water to halt cooking. Drain again and set aside.
02 - In a large skillet over medium heat, toast sliced almonds, stirring frequently, until golden and fragrant, about 2 to 3 minutes. Remove almonds and set aside.
03 - Using the same skillet, heat olive oil over medium heat. Add minced garlic and sauté for 30 seconds until fragrant but not browned.
04 - Add blanched green beans to the skillet and sauté for 3 to 4 minutes, stirring occasionally, until heated through and lightly coated with oil and garlic.
05 - Stir in fresh lemon juice, lemon zest, salt, and black pepper. Toss thoroughly to combine flavors.
06 - Transfer green beans to a serving dish and sprinkle toasted almonds on top. Serve immediately.
