Trim the ends from the green beans and rinse them well.
Bring a large pot of salted water to a boil. Add the green beans and cook for 3–4 minutes, just until bright green and slightly tender. Drain and set aside.
In a large skillet over medium heat, melt the butter.
Add the minced garlic and cook for 30–60 seconds, until fragrant but not browned.
Add the green beans to the skillet and toss to coat in the garlic butter.
Season with salt and pepper and sauté for 2–3 minutes, until the beans are tender-crisp.
