It typically includes a dashi broth, which is a stock made from kombu (seaweed) and katsuobushi (dried bonito flakes). The soup is often garnished with ingredients like tofu, green onions, and seaweed. Miso soup is commonly served as a side dish in Japanese cuisine and is enjoyed for its savory flavor and health benefits. It is rich in probiotics and can be customized with various vegetables and proteins, making it a versatile and nourishing meal option.
