01 - Fill a large pot with water and bring to a boil. Add a generous pinch of salt to season the cooking liquid.
02 - Add the green beans to the boiling water and cook for 3–4 minutes, until bright green and just tender. Drain and immediately transfer to a bowl of ice water to stop the cooking process. Drain again and pat dry.
03 - In a large skillet over medium heat, add the sliced almonds. Toast, stirring frequently, for 2–3 minutes until golden and fragrant. Transfer to a plate and set aside.
04 - In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for 30 seconds until fragrant, being careful not to burn it.
05 - Add the blanched green beans, salt, and pepper to the skillet. Toss to coat evenly with the garlic butter and cook for 2–3 minutes until heated through.
06 - Remove from heat. Add the lemon zest and juice, then toss gently to distribute the citrus flavor evenly throughout the dish.
07 - Sprinkle with the reserved toasted almonds just before serving to maintain their crisp texture.
