01 - Bring a large pot of salted water to a boil. Add green beans and blanch for 2–3 minutes until bright green and crisp-tender. Drain and immediately transfer to a bowl of ice water to stop cooking. Drain again and pat dry.
02 - In a large skillet, heat olive oil over medium heat. Add sliced almonds and cook, stirring frequently, until golden and fragrant, about 2 minutes. Transfer almonds to a plate and set aside.
03 - In the same skillet, add minced garlic and sauté for 30 seconds until fragrant. Add green beans and toss to coat in the oil and garlic.
04 - Stir in lemon zest, lemon juice, salt, and pepper. Sauté for another 2–3 minutes until beans are heated through.
05 - Remove from heat, sprinkle toasted almonds over the beans, and serve immediately.
