Steps
Before you start
- Gather all ingredients and have them at room temperature
- Have a clean glass jar or container (at least 16 oz / 500 ml) ready for storing the marinated mushrooms
Prepare the Mushrooms
- Clean the mushrooms with a damp cloth or soft brush to remove any dirt; avoid soaking them in water.
- Trim any dark or dried stem ends.
- Cut larger mushrooms into halves or quarters so all pieces are roughly the same size (about 1½ inches / 4 cm); leave very small mushrooms whole.
- You should have about 6–7 cups of mushroom pieces.

Ready when: Mushroom pieces are uniform in size and cleaned
Tip: Mushrooms absorb water readily; use a soft cloth or brush instead of rinsing to keep them from becoming soggy.
Make the Marinade
- In a small bowl, whisk together the coconut aminos, sesame oil, rice vinegar, maple syrup, minced ginger, minced garlic, and lime juice until well combined and emulsified.
- Taste the marinade and adjust: add more lime juice if you want brightness, more maple syrup for sweetness, or more sesame oil for richness.
- If using chili flakes, add them now and stir to distribute evenly.

Ready when: Marinade is well mixed and appears emulsified
Tip: Whisk vigorously for about 30 seconds to help emulsify the sesame oil and ensure flavors are evenly distributed.
Combine and Marinate
- Place the prepared mushrooms in the glass jar or container.
- Pour the marinade over them and gently toss until all pieces are evenly coated.
- Cover and refrigerate for at least 30 minutes.
- For deeper flavor, let them marinate for up to 4 hours.
- After 15 minutes, gently stir the mushrooms to redistribute the marinade and ensure even marinating.

Ready when: Mushrooms are tender and have absorbed the flavors, with a slight firmness remaining; liquid should be aromatic
Tip: The flavors intensify over time, so consider marinating for 2–4 hours if you have the time for a more complex result.
Garnish and Serve
- Transfer the mushrooms and all their marinade to a serving bowl.
- Scatter sliced scallions and sesame seeds over the top if using.
- Serve chilled or at room temperature as a side dish, in a grain bowl, or alongside proteins.

Tip: If using sesame seeds, toast them in a dry skillet over medium heat for 2–3 minutes just before serving for maximum flavor and aroma.
Good to know
Tips
- Toast your own sesame seeds in a dry skillet over medium heat for 2–3 minutes just before serving for maximum flavor and freshness.
- This marinade also works beautifully on raw vegetables like zucchini strips, snap peas, bell peppers, carrots, or on firm tofu cubes for a vegan twist.
- For a warm version, sauté the marinated mushrooms in a hot skillet over medium-high heat for 2–3 minutes until heated through, then serve warm with the remaining marinade drizzled on top.
- Make a double batch of the marinade to use as a dipping sauce or dressing for grain bowls, salads, and rice throughout the week.
Make ahead
The marinade can be prepared up to 1 day ahead and stored in an airtight container in the refrigerator. Assemble the mushrooms with the marinade up to 24 hours before serving; the flavors deepen over time.
Storage & reheating
Refrigerator: Up to 4 days in an airtight container. The flavors actually improve on days 2–3. Room temperature: Not recommended for food safety; keep refrigerated. Freezer: Not recommended; mushrooms will become mushy when thawed. To serve: Transfer to a serving bowl and serve chilled or at room temperature.
Substitutions
- coconut aminos (or tamari) → Tamari or low-sodium soy sauce. Tamari has a similar umami depth and is often gluten-free. Use the same amount. Regular soy sauce may be slightly saltier, so taste as you go.
- toasted sesame oil → Avocado oil or grapeseed oil. You'll lose the toasted sesame aroma and nuttiness, so consider adding ½ teaspoon of sesame seeds to the marinade for depth.
- rice vinegar → Apple cider vinegar or white wine vinegar. Use equal amounts. Apple cider vinegar adds subtle sweetness; white wine vinegar will be slightly more acidic.
- mushrooms (cremini, shiitake, oyster, or a mix) → Firm tofu cubes, cauliflower florets, or tempeh cubes. These hold up well in cold marinades and absorb flavors similarly. Adjust marinating time to 1–2 hours for tofu and tempeh.
