How to Make Japanese New Year Mochi Soup

Prepare the Kanto Style Soup Base: In a medium pot, combine 2 cups of water and 2 tsp of kombu dashi over medium-high heat. Stir in the sake, soy sauce, and salt until well blended.
-
Simmer the Veggies: Add the sliced carrots, daikon, and shiitake mushrooms to the pot. Bring the mixture to a boil, then reduce the heat and simmer for about 5-8 minutes, until the carrots and daikon are tender.

Assemble the Bowl: In a serving bowl, place 1-2 pieces of mochi along with the cooked carrots, daikon, and shiitake mushrooms. Gently pour the hot soup over the ingredients and garnish with fresh green onions.
-
Prepare the Kansai Style Soup Base: For a different twist, add 2 cups of water and 2 tsp of kombu dashi into another medium pot and warm over medium heat. Once it simmers, stir in the carrots, daikon, and shiitake mushrooms, and cook for another 5-8 minutes until tender. Remove from heat.
-
Mix in the Miso: Using a sieve, add 2-2.5 tbsp of white miso paste into the soup. Stir until the miso dissolves completely, ensuring a smooth consistency.

Expert Tips for Japanese New Year Mochi Soup
-
Choose Quality Dashi: Use high-quality kombu dashi to enhance the umami flavor; pre-packaged dashi can sometimes lack depth.
-
Avoid Clumpy Miso: To prevent clumps in your soup, always dissolve the white miso paste in a sieve before adding it to the broth for a smooth texture.
-
Cook Mochi Carefully: Ensure that your mochi is boiled until it floats, but don’t overcook, as this can cause it to become too chewy.
-
Customize Your Veggies: Feel free to add seasonal vegetables; just remember to cut them uniformly for even cooking in this Japanese New Year Mochi Soup.
-
Serving Fresh: Ozoni is best when served immediately. Keep the broth hot until you’re ready to pour it over the ingredients for the most comforting experience.
How to Store and Freeze Japanese New Year Mochi Soup
Fridge: Store leftover soup in an airtight container for up to 3 days. Keep the mochi separate to prevent it from getting soggy.
Freezer: Freeze the soup without mochi for up to 1 month. Pour into freezer-safe containers, leaving some space for expansion.
Reheating: Thaw overnight in the fridge and reheat on the stovetop until hot. Add freshly made mochi for best texture.
Avoid Freezing: Do not freeze mochi after it’s cooked, as it can change texture; prepare fresh mochi when serving the thawed soup.
Make Ahead Options
Japanese New Year Mochi Soup is ideal for busy home cooks looking to save time without sacrificing flavor! You can prepare the soup base (without miso) and the cooked vegetables up to 3 days in advance. Simply refrigerate the soup base in an airtight container until you’re ready to enjoy. On the day of serving, reheat the soup and stir in the miso until fully dissolved. Meanwhile, you can make the mochi rice cakes and store them in the fridge for up to 24 hours. When you’re ready to eat, quickly boil the mochi for a couple of minutes and assemble your bowls with the reheated soup and vegetables. This way, your Japanese New Year Mochi Soup will taste just as delicious, all while maximizing your meal prep efficiency!

Japanese New Year Mochi Soup Recipe FAQs
What type of dashi should I use for Japanese New Year Mochi Soup?
Absolutely! For the best flavor, I recommend using high-quality kombu dashi. This seaweed-based broth is rich in umami and essential for creating a flavorful base for your Ozoni. If you’re pressed for time, a pre-packaged dashi can be convenient, but the taste may not be as deep.
How should I store leftover Japanese New Year Mochi Soup?
You can store leftover soup in an airtight container in the fridge for up to 3 days. Just make sure to keep the mochi separate to prevent it from becoming soggy. When you’re ready to enjoy it again, simply heat the soup on the stove until hot and add fresh mochi if you can!
Can I freeze Japanese New Year Mochi Soup?
Certainly! Without the mochi, you can freeze the soup for up to 1 month. Pour it into freezer-safe containers, but leave some space for expansion as it freezes. To reheat, thaw in the fridge overnight and warm it on the stove until piping hot. I often make fresh mochi while the soup heats for a delightful experience!
How can I avoid clumpy miso in my soup?
Very easy! To prevent clumps of miso in your soup, always use a sieve when adding the white miso paste. Measure out the miso into the sieve and stir it in gently until dissolved; this ensures a beautifully smooth broth without any lumps.
What vegetables can I use in Japanese New Year Mochi Soup?
You can customize your soup with seasonal vegetables! Carrots, daikon, and shiitake mushrooms are traditional, but feel free to experiment. Just remember to cut them into uniform sizes for even cooking. Spinach adds a lovely color and can enhance the nutritional value too, so the more the merrier!
Can I make this recipe vegan?
Definitely! To make the Japanese New Year Mochi Soup vegan, simply replace the sake with a little extra water and omit any non-vegan ingredients like soft tofu. Use vegetable broth instead of dashi for a plant-based version while keeping all the delightful flavors intact!
