01 - Bring a large pot of salted water to a boil. Add green beans and cook for 2–3 minutes until just tender and bright green. Drain and immediately plunge into a bowl of ice water to stop cooking. Drain again and set aside.
02 - In a large skillet over medium heat, melt the butter. Add sliced almonds and toast, stirring frequently, until golden (about 2 minutes).
03 - Add minced garlic and cook for 30 seconds until fragrant.
04 - Add the drained green beans to the skillet. Toss to coat with butter, almonds, and garlic.
05 - Add the lemon zest and juice. Season with salt and pepper. Sauté for another 2–3 minutes, stirring, until beans are heated through and well coated.
06 - Serve immediately, garnished with extra toasted almonds if desired.
