1. Start by bringing a large pot of salted water to a boil. Add the green beans and blanch for about 3-4 minutes, until they’re bright green and tender-crisp. My kids always loved helping with this part, watching the beans transform in color.
2. Drain the beans and immediately place them in a bowl of ice water to stop the cooking process. This step ensures they stay nice and crunchy.
3. In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute, just until fragrant, but be careful not to let it burn.
4. Add the butter to the skillet. Once melted, toss in the blanched green beans, stirring to coat them evenly in the garlic butter. Season with salt and pepper to taste.
5. If you’re using lemon juice, add it now for a fresh, zesty finish that brightens the dish.
6. Sauté the beans for another 2-3 minutes, making sure they’re heated through and well-coated with the garlic butter.

When making this dish, I’ve learned that timing is everything. Keep an eye on the garlic and green beans to avoid overcooking, which was a lesson I learned the hard way during one of my early cooking adventures.
