For the best results, the cooking time for ramen noodles in the microwave is 2 minutes on high. Microwaving instant ramen noodles is quick and easy, but it's essential to do it correctly, so you don't end up with a messy or undercooked dish. When microwaving ramen, set the power to high and cook for two minutes. After two minutes, flip the noodles and give them a good stir. Then cook for an additional 30 seconds or until they are cooked through. Be careful not to overcook the noodles, as they can become mushy and difficult to eat. If you're unsure if they're done, err on the side of caution and take them out of the microwave sooner rather than later.
