Step 1

Combine the green beans, butter, water, and garlic cloves in a large skillet. Sprinkle generously with salt and pepper. Cover the pot, place over medium-high heat, and bring to a simmer, then immediately turn heat to low once water is simmering.

Step 2

Cook for 8 minutes, stirring occasionally until the beans are cooked through but not mushy. Uncover. Toss the beans in their sauce and taste. Adjust with salt and pepper to taste, then transfer the beans to a serving dish. Shave parmesan over the top if you wish. Crack more pepper over the top if you wish, too.
