Ingredients for Miso Butter Mushrooms

Gathering the right ingredients makes all the difference with this simple yet flavorful dish. Here’s exactly what you’ll need, down to the type of miso and how to prep those mushrooms:

• 500g mushrooms – I use a mix of cremini and shiitake for depth of flavor, but button mushrooms work great too (slice them about 1/4-inch thick)
• 2 tbsp unsalted butter – The real, good-quality stuff is key here (none of that margarine business!)
• 1 tbsp white miso paste – This is the mildest type and blends beautifully (look for it in refrigerated sections)
• 1 tbsp soy sauce – Regular or low-sodium, your choice (I like the umami punch of full-strength)
• 1 clove garlic – Finely minced (or grate it if you’re feeling lazy like I sometimes am)
• 1 tsp sesame oil – That toasty fragrance at the end makes everything better
• 1 tbsp chopped green onions – Both white and green parts for garnish (scissors make quick work of these)

A quick note about the miso – if your paste seems thick, give it a good stir in its container first. And don’t skip pre-slicing your mushrooms – trying to cook them whole would lead to uneven cooking and sauce distribution (I learned this the hard way!).

How to Make Miso Butter Mushrooms

Now for the fun part – turning these simple ingredients into a dish that’ll have everyone asking for seconds. I’ve made this recipe so many times I could do it in my sleep, but I’ll walk you through each step so your miso butter mushrooms turn out perfectly the first time.

Step 1: Sauté the Mushrooms

Grab your favorite large skillet (I use a 12-inch cast iron because it heats evenly) and set it over medium heat. Add the butter and let it melt until it just starts to bubble – that’s when you know it’s ready. Now toss in those sliced mushrooms! Here’s my big tip: don’t crowd the pan. If you pile them all in at once, they’ll steam instead of getting that beautiful golden sear. I usually cook them in two batches if my pan looks too full.

Let them cook undisturbed for about 3 minutes to get some color, then give them a good stir. You’ll know they’re ready when they’ve shrunk by about half and have that irresistible golden-brown color – usually about 5-7 minutes total.

Step 2: Add the Miso Butter Sauce

This is where the magic happens! Push your mushrooms to one side of the pan and add the garlic to the empty space. Let it sizzle for just 30 seconds until fragrant (don’t let it burn!). Now here’s my trick for perfectly smooth miso butter sauce: in a small bowl, mix the miso paste with the soy sauce first until it forms a smooth paste. This prevents those annoying miso clumps!

Pour this mixture over the mushrooms along with any mushroom juices that have collected. Use your wooden spoon to scrape up any delicious browned bits from the pan bottom – that’s where so much flavor lives! Keep stirring until every mushroom is beautifully coated in that glossy sauce, about 2-3 minutes. You’ll know it’s perfect when the sauce clings to the mushrooms instead of pooling at the bottom.

Finish with a drizzle of sesame oil and sprinkle with those fresh green onions. Trust me, the aroma at this point is absolutely heavenly. Your miso butter mushrooms are ready to serve – though I won’t judge if you sneak a taste (or three) straight from the pan!

• Works for any meal – These miso butter mushrooms shine as a side with steak, tossed with noodles, piled on toast, or even as the star of a grain bowl. Leftovers? I’ve been known to eat them cold straight from the fridge – they’re that good.

Tips for Perfect Miso Butter Mushrooms

After making this dish countless times (and yes, making plenty of mistakes along the way), I’ve learned all the little tricks that take miso butter mushrooms from good to can’t-stop-eating-them amazing. Here’s what you need to know to nail it every time:

How to avoid the dreaded miso clumps

We’ve all been there – you stir miso directly into the pan and suddenly you’ve got little flavor bombs floating around instead of a smooth sauce. My foolproof method? Always mix the miso paste with the soy sauce first in a small bowl until it’s completely smooth. The liquid helps the miso dissolve evenly. If it’s still being stubborn, add a teaspoon of warm water to help it along.

Getting the mushrooms just right

Overcooked mushrooms turn rubbery, while undercooked ones can be watery. The sweet spot? You want them golden brown with a slight bite – what chefs call “al dente.” Here’s my test: when you press a mushroom slice with your spatula, it should offer slight resistance but not feel hard. And remember – they’ll keep cooking a bit in the warm sauce after you take them off the heat!

Taste as you go – seriously!

Different miso brands and soy sauces vary in saltiness, so always taste your sauce before serving. Too salty? A squeeze of lemon or splash of water balances it. Need more punch? Add an extra half teaspoon of miso. I usually adjust mine with a pinch of sugar if the miso tastes too sharp – it rounds out the flavors beautifully.

A few bonus tips from my kitchen to yours: wipe mushrooms clean with a damp towel instead of washing them (they absorb water like sponges!), and always wait to salt until the end since the soy sauce and miso already bring plenty of saltiness. Oh, and that delicious sauce pooling at the bottom? Spoon it over your rice – that’s liquid gold!

Ingredient Substitutions & Notes

One of the best things about miso butter mushrooms is how forgiving the recipe is – I’ve made it with all sorts of variations when my pantry was looking bare. Here are my tried-and-true swaps and important notes to keep in mind:

Mushroom options beyond the basics

While I love cremini for their meaty texture, any mushroom works here! Oyster mushrooms add beautiful frilly edges that catch extra sauce, while portobellos give a steak-like heartiness (just slice them thinner). For special occasions, splurge on maitake or king trumpet mushrooms – their robust structure stands up beautifully to the rich sauce.

Alternative sauces for dietary needs

No soy sauce? No problem! Coconut aminos make a great gluten-free substitute with similar umami depth (use about 1 1/4 tablespoons since it’s slightly sweeter). For a lower-sodium version, I’ll sometimes use tamari mixed with a teaspoon of water. And if you’re out of sesame oil, a drizzle of toasted sesame seeds adds that nutty finish.

Miso paste wisdom

White miso (shiro) is my go-to for its mild sweetness, but red miso (aka) works if you prefer a bolder, saltier kick – just start with 2 teaspoons and adjust to taste. And here’s something I learned the hard way: miso lasts forever in the fridge (like, years), but it does darken and intensify over time. If yours has been chilling in the back of your fridge since last Christmas, just use a bit less than the recipe calls for.

A few more quick notes: vegan? Swap the butter for a good olive oil or vegan butter (the flavor changes slightly but still tastes amazing). Out of fresh garlic? A quarter teaspoon of garlic powder stirred into the sauce works in a pinch. And if green onions aren’t your thing, try chopped chives or even a sprinkle of furikake for extra crunch.

Serving Suggestions for Miso Butter Mushrooms

Honestly, I’ve eaten these miso butter mushrooms straight from the pan with a spoon (no shame!), but they really shine when paired with the right companions. Here are my favorite ways to serve them – each one transforms this simple dish into something special:

Over a bed of steaming rice

This is my weeknight lifesaver – just spoon those glossy mushrooms and all their saucy goodness over freshly cooked white or brown rice. The grains soak up every drop of that umami-packed sauce. Sometimes I’ll sprinkle on some toasted sesame seeds or nori flakes for crunch. Pro tip: use slightly less water when cooking the rice so it can handle all that delicious sauce without getting mushy!

Tossed with noodles

For a heartier meal, I love mixing the mushrooms with udon or soba noodles. The thick, chewy strands catch all the sauce beautifully. Just cook the noodles al dente, reserve a bit of the starchy cooking water, and toss everything together with an extra pat of butter if you’re feeling indulgent. A soft-boiled egg on top makes it a complete meal.

Alongside grilled proteins

These mushrooms play incredibly well with others! I often serve them as a side to:

• Pan-seared salmon (the richness pairs perfectly)
• Grilled chicken thighs (the crispy skin loves that miso butter)
• Seared steak (because butter makes everything better)

The mushrooms make even simple grilled tofu feel fancy. Just spoon them right over the top and watch how quickly they disappear!

As a toast topper

Here’s my secret breakfast upgrade: thick sourdough toast slathered with a thin layer of miso butter (just mix equal parts!), then piled high with these mushrooms. Top with a fried egg if you’re really hungry. The combination of crispy bread, creamy yolk, and savory mushrooms is downright addictive.

Lately I’ve been getting creative – these mushrooms are amazing folded into omelets, stirred into risotto during the last few minutes of cooking, or even as a pizza topping with mozzarella. The possibilities are endless, and I’d love to hear how you serve yours!

Storing and Reheating

If by some miracle you have leftovers (I rarely do!), here’s how to keep your miso butter mushrooms tasting just as delicious as when they first came out of the pan. The key is preserving that perfect texture and preventing the sauce from breaking.

Refrigerator storage tips

These mushrooms keep beautifully in the fridge for 3-4 days in an airtight container. I always let them cool completely before storing – trapping steam leads to sogginess. Pro tip: leave any green onion garnish off until serving so it stays fresh and crisp. The sauce actually gets more flavorful as it sits, making leftovers something to look forward to!

Can you freeze miso butter mushrooms?

While you can freeze them for up to 2 months, I’ll be honest – the texture changes. Mushrooms become slightly softer when thawed. If you must freeze, do it in portions with all the sauce (that’s where the flavor lives!). Thaw overnight in the fridge, then reheat gently to minimize texture loss.

The best reheating methods

For stovetop magic: Warm them over medium-low heat with a splash of water or broth to loosen the sauce. Stir frequently – this keeps everything evenly heated without overcooking. Microwave works in a pinch (cover with a damp paper towel), but stir every 30 seconds to prevent rubbery spots.

My secret weapon? Toss cold leftovers directly into hot rice or noodles – the residual heat warms them perfectly while keeping their texture intact. And if the sauce seems too thick after storage, a teaspoon of warm water stirred in brings it back to silky perfection.

Miso Butter Mushrooms Nutrition

Nutrition varies by ingredients – these values are estimates per serving based on my standard recipe, but your exact numbers might differ slightly depending on mushroom size, miso brand, or how much sauce you spoon over your plate (I always go heavy on that goodness!). Here’s the nutritional breakdown for one serving (about 1/4 of the recipe):

• Calories: 120
• Fat: 8g (4g saturated, 3g unsaturated)
• Protein: 4g
• Carbohydrates: 9g
• Fiber: 2g
• Sugar: 3g
• Sodium: 450mg

Now, I’m no nutritionist, but here’s what I love about these numbers – you’re getting a good dose of plant-based protein from the mushrooms, plus all those gut-friendly probiotics from the miso. The fat content might look high at first glance, but it’s mostly the good kind from butter and sesame oil that helps your body absorb all the nutrients. And that fiber? It comes naturally from the mushrooms – no weird additives here!

If you’re watching sodium, you can easily adjust by using low-sodium soy sauce or reducing the miso slightly (though I’d miss that punch of flavor). And for my carb-conscious friends – this dish is naturally low-carb friendly when served over veggies instead of rice. But honestly? Sometimes you just need to enjoy every buttery, umami-packed bite without overthinking it – life’s too short not to! Discover even more creative and flavorful recipes by following us on Facebook.
