A Rainy Afternoon in Tokyo

Print

I’ll never forget the first time I truly fell in love with miso-glazed mushrooms. It was on a drizzly, grey afternoon in Tokyo. My husband and I had been exploring tiny backstreets all day, and the damp chill had seeped right into our bones. We ducked into a tiny, steam-filled izakaya (a Japanese pub) that was barely bigger than my walk-in pantry. We squeezed onto stools at the counter, and without even looking at a menu, the chef placed a small, sizzling clay dish in front of us.

It was mushrooms. But not just any mushrooms. They were glistening with a dark, sticky glaze, smelling intensely of garlic, ginger, and that profound, savory richness I now know as umami. We spooned them over bowls of plain white rice, and with that first bite, everything changed. The cold was gone, replaced by a wave of pure comfort. It was one of the most soul-satisfying, simple, and perfect bites of food I’ve ever had. I’ve been trying to recreate that feeling in my own kitchen ever since, and this recipe is my love letter to that rainy day in Tokyo and the powerful magic of simple, incredible food.

Gathering Your Flavor Powerhouses

Here’s the beautiful part: this incredible flavor comes from just a few key players. Let’s break them down!

• 300g Mixed Mushrooms (shiitake, oyster, button): Using a mix is my chef’s secret! Shiitake bring a deep, almost smoky woodsiness. Oyster mushrooms have a delicate, velvety texture that soaks up the sauce beautifully. Button or cremini mushrooms provide a familiar, meaty base. Chef’s Insight: Don’t wash them under water! Just wipe them clean with a damp paper towel to keep them from getting soggy.
• 1 Tbsp Sesame Oil: This is our flavor foundation. Its distinct nutty aroma is non-negotiable for that authentic taste. Sub Tip: If you’re out, any neutral oil (like avocado or grapeseed) works, but you’ll lose a layer of flavor.
• 1 Tbsp White Miso Paste: The star of the show! White miso (shiro miso) is fermented soybean paste that’s milder, slightly sweet, and less salty than other varieties. It’s packed with gut-friendly probiotics and that incredible fifth taste, umami. Chef’s Insight: Always add miso off direct heat or diluted in liquid to preserve its beneficial bacteria and prevent bitterness.
• 1 Tbsp Soy Sauce: Our salty, savory backbone. It amplifies the umami of the miso. Sub Tip: Use tamari for a gluten-free option, or coconut aminos for a soy-free version (though it will be slightly sweeter).
• 1 Tbsp Mirin: This sweet Japanese rice wine adds a gentle sweetness and glossy sheen to our glaze. Sub Tip: No mirin? Mix 1 tsp of rice vinegar with 2 tsp of sugar or maple syrup. It’s not perfect, but it works in a pinch!
• 1 Tsp Grated Ginger & 1 Garlic Clove, minced: The aromatic dream team! They provide a bright, pungent kick that cuts through the richness. Chef’s Insight: Use fresh here, please! The jarred stuff just doesn’t provide the same vibrant punch.
• Optional Garnishes: Sliced spring onions for fresh crunch, toasted sesame seeds for nutty texture, and chili flakes for a welcome kick of heat. Don’t skip these—they make the dish pop!

Let’s Get Cooking: Your Foolproof Steps

Ready? Apron on, pan out—let’s do this! This process is quick, so it helps to have all your ingredients prepped and within arm’s reach (that’s your mise en place, making you feel like a pro already!).

Step 1: Prep Your ‘Shrooms. Take your beautiful mixed mushrooms. If using shiitake, discard the tough stems. For oyster mushrooms, you can tear them into rustic, natural-looking pieces. Slice the button mushrooms. Remember, we’re wiping them, not washing them! The goal is to get them nice and dry so they sear instead of steam. This is the first secret to deeply flavorful mushrooms.

Step 2: Wake Up the Aromatics. Place your skillet or frying pan over medium heat. Add that glorious sesame oil and let it get warm. You’ll know it’s ready when you can smell its nutty fragrance. Now, add the minced garlic and grated ginger. Listen to that sizzle! Cook them for just about 60 seconds—until they are fragrant but not browned. We’re just waking up their flavors, not burning them. Burnt garlic is bitter, and we don’t want that in our happy dish.

Step 3: Sauté to Golden Perfection. Time for the main event! Add all your mushrooms to the pan. They might seem like a lot, but they’ll cook down significantly. Here’s my biggest chef hack: DON’T overcrowd the pan. If you pile them all in a small pan, they’ll steam and get soggy. If needed, cook them in two batches. Let them cook, without stirring too much, for a couple of minutes to get a nice sear. Then, give them a toss and continue cooking for 5-7 minutes total, until they are beautifully golden brown, tender, and have released their moisture.

Step 4: Create the Magic Glaze. While the mushrooms are working their magic, grab a small bowl. Add the white miso paste, soy sauce, and mirin. Whisk it together until it’s a smooth, lump-free sauce. This is your flavor bomb, ready to deploy!

Step 5: Bring It All Together. Once your mushrooms are perfectly cooked, reduce the heat to low. This is crucial! Now, pour your miso glaze over the mushrooms. Stir quickly and constantly to coat every single mushroom in that glossy, savory sauce. Let it cook for just another 1-2 minutes until the glaze thickens, clings to the mushrooms, and becomes sticky and irresistible. And that’s it! You did it!

How to Serve These Savory Gems

The fun part! How will you enjoy your creation? For a classic, comforting meal, spoon them over a fluffy mound of steamed jasmine or short-grain rice—the sauce mingling with the rice is everything. Toss them through a pile of soba or udon noodles for a fantastic lunch. For a light, low-carb option, they are incredible stuffed into crisp butter lettuce or romaine cups. And don’t forget they make a phenomenal side dish to seared salmon, roasted chicken, or even a simple tofu scramble. Finish with a flurry of green spring onions, a sprinkle of sesame seeds, and maybe a pinch of chili flakes for those who like a bit of heat.

Make It Your Own: Delicious Twists

This recipe is a wonderful canvas—feel free to get creative!

• Spicy Miso Mushrooms: Add 1-2 teaspoons of gochujang (Korean chili paste) or a big squeeze of Sriracha to the miso glaze mixture.
• Creamy Miso Ramen Topping: Stir in a tablespoon of tahini or a splash of coconut milk into the glaze at the end for a richer, creamier sauce perfect for ramen.
• Miso Mushroom Stir-Fry: Add sliced bell peppers, snap peas, and carrots with the mushrooms for a full veggie stir-fry.
• Protein-Powered Version: Add cubed firm tofu or tempeh to the pan when you sauté the mushrooms to make it a heartier main.

Anna’s Chef Notes & Kitchen Stories

This recipe has evolved so much in my kitchen over the years. My first attempt was… a learning experience. I added the miso paste directly to the hot pan, and it instantly seized up and burned, creating a bitter, chalky mess. Lesson learned! Now, I always mix it with other liquids first. I’ve also learned that patience with the mushrooms is key. Let them sear and get properly brown—that’s where the deep flavor comes from, not just the sauce.

This dish has become my go-to for last-minute guests. It feels fancy and complex, but we know the truth—it’s wonderfully simple. I love serving it as part of a shared meal with other small plates. It always, without fail, elicits an “Mmm, what is this?!” followed by recipe requests. It’s a little bowl of joy, and I’m so excited to share it with you.

Your Questions, Answered!

Q: My sauce turned out grainy and didn’t coat the mushrooms smoothly. What happened?
A: This usually happens if the miso isn’t fully dissolved before hitting the heat. My trick is to mix the miso paste with the soy sauce and mirin in a separate bowl first, ensuring it’s completely smooth and lump-free. Adding it directly from the tub is a risky move!

Q: My mushrooms released a ton of water and are boiling instead of browning. Help!
A: Two likely culprits! First, your pan might be overcrowded. Mushrooms need space to evaporate their moisture and brown. Cook in two batches if your pan is small. Second, the heat might be too low. You want a solid medium heat to encourage browning. If a pool of liquid forms, just let it cook off—it will eventually evaporate and then the browning can begin.

Q: Can I make this ahead of time?
A: Absolutely! You can cook the mushrooms and make the sauce separately. Store them in the fridge for up to 2 days. When ready to serve, reheat the mushrooms in a pan and then stir in the sauce to warm through. I don’t recommend freezing, as the texture of the mushrooms can become rubbery.

Q: I can’t find mirin. What’s the best substitute?
A: No worries! The best quick substitute is 1 teaspoon of rice vinegar mixed with 2 teaspoons of sugar, maple syrup, or honey. It will give you that needed balance of sweet and tangy.
