Simmered Shiitake Mushrooms (Fukumen i) – Umami in Its Purest Form

Why You’ll Love This Recipe

This Simmered Shiitake Mushroom recipe, known in Japan as Fukumen i, highlights everything we love about shiitake: deep umami, delicate texture, and versatility. Slowly simmered in a sweet-savory soy broth, the mushrooms soak up flavor until they’re tender and aromatic — the kind of humble dish that quietly steals the spotlight.

Whether you’re plating a refined kaiseki-style meal or preparing a simple rice bowl at home, this dish adds warmth and depth to any table.

Ingredients

(Serves 2–3)

• 10–12 dried shiitake mushrooms (or fresh shiitake if preferred)

• 1 ½ cups water (plus more for soaking)

• 2 tbsp soy sauce

• 2 tbsp mirin

• 1 tbsp sake

• 1 tbsp sugar (adjust to taste)

• Optional: a small piece of kombu (kelp) for added umami

Instructions

1. Soak the mushrooms:
   Place dried shiitake in a bowl and cover with warm water. Let soak for at least 1 hour (or overnight in the fridge). Once soft, gently squeeze excess water and reserve the soaking liquid.

2. Prepare the simmering broth:
   In a small saucepan, combine 1 ½ cups of the soaking liquid (strain to remove grit), soy sauce, mirin, sake, and sugar. Add kombu if using.

3. Simmer:
   Add the softened shiitake to the pan. Bring to a gentle boil, then lower heat and simmer uncovered for 15–20 minutes until most of the liquid reduces and becomes slightly syrupy.

4. Serve or store:
   Serve warm or at room temperature as a side dish, sushi topping, or addition to ramen, soba, or rice bowls. The mushrooms can also be stored in the fridge (in their cooking liquid) for up to 4 days — they get even better with time.

Chef’s Tip

For the best flavor, use dried shiitake mushrooms, as they concentrate umami during dehydration. The soaking liquid is liquid gold — always reuse it as your simmering base or in soups.

Pairing Ideas

This dish pairs beautifully with sake, light Pinot Grigio, or Czech Riesling. The sweet-savory balance also complements miso soup, steamed rice, or grilled vegetables.
