The duration required to cook green beans in an oven set to 350 degrees Fahrenheit is a crucial element in achieving the desired texture and flavor. Overcooking results in limp, mushy beans, while undercooking leaves them crisp and potentially unpalatable. Proper timing ensures the beans are tender-crisp, retaining their vibrant green color and nutritional value.
Accurate cooking time is essential for maximizing the nutritional benefits and culinary appeal of green beans. Baking, as a method, promotes even heat distribution, leading to consistent doneness. Historically, roasting vegetables, including green beans, has been a technique employed to enhance their natural sweetness and create a more complex flavor profile compared to boiling or steaming.
