Step 1

Rinse and trim the beans. Rinse the green beans under cool water and shake dry. Trim the stem end from the beans and halve any very long beans.

Step 2

Sauté the beans. Heat the oil in a large straight-sided skillet over medium-high heat until shimmering. Add the green beans and cook, stirring often, until the beans are bright and glossy, 5 to 7 minutes.

Step 3

Season the beans. Add the garlic and salt. Cook, stirring constantly, until the garlic is fragrant, about 30 seconds.

Step 4

Steam the beans. Add the water and immediately cover. Cook covered until the beans are bright green and crisp-tender, 1 to 2 minutes.

Step 5

Serve. Add the red pepper flakes, if using, and serve immediately.
