This soup is incredible; I could hardly stop eating it. It’s light and different and so flavorful, and it’s quick to make.
It’s based upon this recipe from Martha Stewart Living magazine, except I leave out the tofu — and even the soba noodles could easily be optional, as they add more in the way of texture and filler, rather than flavor. The real flavor is from the broth, squash, mushrooms, and scallions. Just like that it is absolutely delicious, and would be a good Paleo dish to add to your repertoire.
Japanese Squash & Mushroom Soup
5 cups water (for out of this world soup, use bone broth — either beef or chicken bones simmered for many hours in water)
3/4 oz dried kombu seaweed (kelp)
1/3 cup dried bonito flakes, lightly packed
2 Tbsp soy sauce, plus more for seasoning (I highly recommend Ohsawa Organic Nama Shoyu!)
1 lb kabocha, buttercup, or butternut winter squash, peeled and cut into 1/2″ dice
3 1/2 oz shiitake mushrooms, sliced if large
8 oz soba noodles, preferably 100% buckwheat (feel free to cut down to 4 oz, or even leave these out altogether)
Scallions, thinly sliced for garnish
***
Boil water and kombu together in a large saucepan. Remove from heat, stir in bonito flakes, and let sit 5 minutes.
Pour through a fine sieve into a bowl, and return liquid (it’s now called “dashi”) to pan. Discard solids, or save only the kombu to reuse.
Add the soy sauce, squash, and mushrooms to the dashi. Bring to a boil over high heat, and then reduce heat, cover, and simmer for about 10 minutes or until the squash is tender. Stir it now and then if you think of it.
While the soup is cooking, cook the soba noodles separately. This is important since 100% buckwheat soba, especially, will turn its cooking water murky and starchy-slimy. So, bring water to a boil (salted or not, your choice) and cook the soba according to the package, about 7 or 8 minutes. Don’t overcook it. When it’s done, drain and rinse in cold water — to stop the cooking and rinse away the starch.
Ladle the soup into bowls, add the soba noodles, and top with scallions. Serve with soy sauce at the table in case anyone would like to add more.
Eat!! Yum!!
