This mushroom dish is inspired by my miso noodles recipe—the sauce is a reader fave, and I'm not surprised. Miso paste adds such a complex combination of flavors: sweet, salty, and packed with umami.
These mushrooms soak it all up and deliver that perfect balance. I love having it as a hearty side for dinner with sirloin steak or spooned over a bowl of fluffy garlic rice.
📖Why My Recipe Works
Miso and soy sauce share similar flavors, so we’re leaving out the soy to let the miso take center stage and really shine.
🧾Ingredient Notes
- Miso Paste- Use white miso paste for a mild taste, or red miso for a deeper flavor. Make sure it's labeled gluten-free if needed.
- Mushrooms- Use baby portobello mushrooms (also called cremini mushrooms) or white button mushrooms.
- Garlic- Use freshly minced garlic for the best flavor.
- Ginger- Use freshly grated ginger or ginger paste.
- Butter- Substitute with vegan butter. You can use olive oil but the taste won't be as rich.
- Honey- Swap with maple syrup to make it vegan.
- Rice Vinegar- Adds acidity to balance the umami. Apple cider vinegar or white wine vinegar works in a pinch.
- Red Pepper Flakes- Adjust to taste, or skip if you don't like spicy.
⏲️How to Make Miso Glazed Mushrooms
- Make sure the butter is fully melted and hot before adding mushrooms. This helps the mushrooms start browning right away instead of steaming.
- Miso paste can be clumpy, so whisk thoroughly with hot water to fully dissolve it before adding it to the pan.
- Let the mushrooms simmer in the sauce over medium-low heat so they absorb flavor without overcooking or burning the sauce.
- Garnish with green onions and sprinkle with sesame seeds, and serve immediately while hot and fresh!
🥗How to Serve Sauteed Mushrooms
Miso butter mushrooms are incredibly versatile—they work perfectly as a side dish or a satisfying vegetarian main.
Some of my favorite ways to enjoy them include serving alongside grilled flank steak, chicken piccata, green beans, or spooned over fried rice for an easy, flavorful meal.
Leftovers are just as delicious when transformed into ramen toppings or used to elevate a simple spice crusted steak dinner.
👩🏻🍳 Expert Tips
- As you pour in the sauce, gently scrape up any browned bits from the pan for extra flavor.
- Taste and adjust to your preference. Miso can vary in saltiness, so taste near the end and adjust with a splash more of water, vinegar, or honey.
