Miso soup is a five-minute bowl with one rule you can’t break: never boil the miso, or you kill the living cultures and the flavor goes flat. Whisk it in off the boil. Here’s how, and where to buy real miso and tofu.

The Ingredients — and where to get them
Cook for4bowls
Miso
Real unpasteurized fermented miso — white for mellow, red for deeper. Whisk it in off the heat to keep it alive.
Can you make Miso Soup in an air fryer? — Yes, with an insert
Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.
Can you freeze Miso Soup? — Yes
Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.
Can you make Miso Soup ahead of time? — Best fresh
Best made fresh and served soon — it loses its edge standing around. You can prep the parts ahead, but finish and serve it close to the table.
Is Miso Soup gluten-free? — Yes
Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.
Is Miso Soup vegan? — No
No — it contains seafood, so it isn’t vegetarian or vegan.
