01 - Bring a large pot of salted water to a boil. Add the green beans and cook for 3–4 minutes until crisp-tender. Drain and immediately transfer to a bowl of ice water to stop the cooking. Drain well and set aside.
02 - In a large skillet over medium heat, add the sliced almonds. Toast, stirring frequently, for 2–3 minutes until golden and fragrant. Transfer almonds to a small bowl and set aside.
03 - In the same skillet, heat olive oil over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant.
04 - Add the drained green beans to the skillet. Toss to coat in the oil and garlic, and cook for 2–3 minutes until heated through.
05 - Remove from heat. Add the lemon zest, lemon juice, and toasted almonds. Season with salt and pepper. Toss well to combine. Serve immediately, garnished with additional lemon zest if desired.
