Japanese Mushroom Soup: A Symphony of Umami

Introduction

Japanese Mushroom Soup is a culinary embodiment of Japan’s deep respect for nature’s gifts. Its origins are humble, rooted in the country’s foraging tradition, where mushrooms were gathered from the wild and used to create nourishing broths. For me, this soup is a reminder of autumn in Japan, where the sight of mushrooms sprouting in the forests signifies a season of harvest and the promise of heartwarming meals.

Cultural Context

In Japanese cuisine, mushrooms are celebrated for their umami—the fifth taste that is savory and deeply satisfying. This soup, with its variety of mushrooms, is often enjoyed during the cooler months and has become a staple in home cooking. It’s not tied to specific events but is a testament to the everyday beauty of Japanese culinary practices.

Health Benefits of Japanese Mushroom Soup

This soup is a nutritional powerhouse. Mushrooms are low in calories but high in fiber and vitamins. Brown rice provides whole grains, and soy milk offers plant-based protein. Together, they create a dish that’s as nourishing as it is delicious.

Ingredient Spotlight

The key ingredients in this soup are a testament to its wholesomeness:

• Brown rice adds a hearty texture and complements the mushrooms’ earthiness.
• Konbu shiitake dashi is the soul of the soup, providing a rich umami base.
• A medley of mushrooms—shimeji, maitake, and shiitake—each contributes its unique flavor and texture.
• Homemade soy milk introduces a creamy dimension without dairy.
• Modern variations might include different types of mushrooms or the addition of other grains like barley.

       

Ingredients

• 1 ½ cups cooked brown rice, short grain
• 1 -2 Tbsp soy sauce
• 1 Tbsp mirin or sake
• 3-4 cups konbu shiitake dashi; use more if you like a soupy soup vs a thick one
• 1 cup of homemade soy milk (unstrained with okara still in it; or store bought)
• 1 ½ cups onion, sliced
• 1 cup shimeji mushrooms
• 1 cup maitake mushrooms
• 1 cup dashigara shiitake mushrooms (used for making dashi; alternatively fresh shiitake)
• 2-3 Tbsp sesame oil or olive oil
• 1 tsp salt
• Freshly cracked black pepper

For toppings 

• soy sauce, balsamic vinegar, la-yu (chili oil), shichimi pepper, tsukudani (seasoned konbu/shiitake)

For serving 

• truffle salted croutons or toast

Instructions

1. Using a saucepan on medium heat, add oil and cook the and onion and mushrooms partially covered until slightly caramelized ~ 8-10 minutes. Stir once or twice for even cooking.
2. After you see some nice browning, add in dashi and scrape any browned bits off the bottom of your pot.
3. Next add salt, brown rice and soy milk, with some cracked black pepper and mix thoroughly.
4. Cook on medium heat for another 5 minutes stirring occasionally. 
5. Use an immersion blender to puree or transfer to a high speed blender for the creamiest smoothest texture.
6. Serve with desired toppings and enjoy! 

Cooking Tips

• Brown rice is a nutritious way to add some thickness and texture to your soup. Pair this with unstrained soy milk and it’s even more buttery, rich and velvety without using any sort of cream or dairy and very little oil.  
• Depending on the mushrooms you can find, the flavor will vary slightly as each has a slightly different flavor. Use your favorite and you’ll enjoy it in a new and tasty way!
• If you’re up for caramelizing the onions, consider making a large batch and use in the soup for a more complex flavor and to garnish on top.

Serving Suggestions

Garnish with truffle salted croutons or toast for a luxurious touch. Top with la-yu or shichimi pepper for a spicy kick, and tsukudani for an extra umami punch.

Variations

Customize your soup by:

• Adding tofu or noodles for a more filling meal.
• Sprinkling green onions or sesame seeds for added flavor and texture.
