01 - Bring a large pot of salted water to a rolling boil. Introduce the trimmed green beans and cook for 3 to 4 minutes until they achieve a vibrant green hue and are just tender-crisp. Promptly drain the beans and immerse them in an ice bath to halt the cooking process. Drain thoroughly once more and set aside.
02 - In a large skillet over medium heat, add the sliced almonds. Toast, stirring frequently, for approximately 2 to 3 minutes, until they are golden brown and aromatic. Transfer the toasted almonds to a plate and reserve.
03 - Using the same skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for 30 seconds, ensuring it becomes fragrant but does not brown.
04 - Return the prepared green beans to the skillet. Toss to coat them evenly with the garlic-infused oil. Continue to sauté for 2 to 3 minutes, allowing the beans to heat through.
05 - Incorporate the lemon zest, fresh lemon juice, salt, and freshly ground black pepper into the skillet. Toss vigorously to ensure all ingredients are well combined and the beans are thoroughly seasoned.
06 - Just prior to serving, sprinkle the reserved toasted almonds over the lemon garlic green beans.
