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 plunge into ice water to stop the cooking. Drain again and set aside.
02 - In a large skillet over medium heat, toast the sliced almonds, stirring frequently, until golden brown and fragrant (2–3 minutes). Remove almonds from the pan and set aside.
03 - In the same skillet, melt the butter with the olive oil over medium heat. Add the minced garlic and sauté for 30 seconds until fragrant.
04 - Add the green beans to the skillet and toss to coat in the garlic butter. Cook for 2–3 minutes until heated through.
05 - Stir in the lemon zest and juice. Season with salt and pepper to taste.
06 - Remove from heat. Sprinkle with toasted almonds and serve immediately.
