The mushrooms are the heart of this dish, so prioritize shiitake for their meaty texture and rich flavor. Local farmers markets often carry fresh shiitake, but if unavailable, cremini or oyster mushrooms work well too. For the crispy topping, yellow onions are ideal—they caramelize beautifully. Look for firm, dry onions with crisp outer layers. The liquid smoke is crucial—Pure Smoke brand is the gold standard, but any high-quality food-grade liquid smoke will do. If you can’t find Grade B maple syrup, Grade A works, but the flavor will be slightly less complex.
No liquid smoke? Smoked sea salt at double the amount adds a similar depth, though not identical. Tamari can be swapped for coconut aminos, but tamari offers more umami. Fresh dill is preferred, but dried dill at one-third the amount works in a pinch. For the crispy topping, cornstarch is non-negotiable—it creates that satisfying crunch. If you’re short on time, pre-sliced onions from the produce section save prep work. The marinade can be made a day ahead, allowing the mushrooms to absorb the flavors more deeply.
Store leftover mushrooms in an airtight container with a paper towel to absorb moisture—keeps for 5 days in the fridge. The crispy onions lose their crunch after 2 days, so make them fresh if possible. For longer storage, freeze the mushrooms in the marinade for up to 3 months. Reheat gently in a skillet to restore crispiness. This dish reheats beautifully, making it perfect for meal prep—just add fresh dill and a squeeze of lemon juice before serving.
Why You’ll Love This Recipe
- I’ll be real: I make this on Sunday and it’s still solid by Wednesday. The mushrooms keep in the fridge for five days if you toss in a paper towel to soak up moisture—no soggy surprises. And if I’m feeling extra, I freeze half for later. No waste, no stress, just deliciousness whenever I crave it.
- No-Pan-Worry Magic: I love that this recipe turns shiitake mushrooms into something so rich they fool even the most skeptical meat-eaters. Just slice those mushrooms, dump them in the marinade with the liquid smoke and tamari, and let them soak while I do something else—no constant stirring, no babysitting the pan.
- Smoky, Sweet, Addictive: The combo of liquid smoke, pure maple syrup, and a splash of white wine vinegar gives these mushrooms a depth that’s chef’s kiss. Honestly, the first bite always makes me pause—it’s that perfect balance of smoky, slightly sweet, and savory. The fresh dill at the end? Game-changer.
- Crowd-Pleaser Every Time: This isn’t just for fancy dinners—it’s my go-to for game day snacks, potlucks, or even a quick lunch with crackers. The crispy onions on top? They add a satisfying crunch that makes it feel like a full meal, not just an appetizer. My friends always ask for the recipe after one bite.
Step-by-Step instructions for marinated mushroom delight
Create a smoky, savory vegan dish that mimics smoked salmon perfectly—crispy onions crown the marinated mushrooms.
Marinate the Shiitake Mushrooms
In a large mixing bowl, combine the 1½ lb shiitake mushrooms (stemmed and sliced), ¼ cup extra-virgin olive oil, 2 tbsp liquid smoke, ¼ cup tamari or gluten-free soy sauce, 2 tbsp pure maple syrup, and 1 tbsp white wine vinegar. Stir until the mushrooms are evenly coated, ensuring the marinade penetrates all slices.
Add the 4 minced garlic cloves, 1 tsp smoked paprika, 1½ tsp salt, and ½ tsp black pepper. Gently toss again, then cover the bowl and refrigerate for at least 4 hours (or overnight for deeper flavor). The mushrooms will absorb the smoky, umami-rich marinade, developing a texture and taste reminiscent of traditional smoked salmon.
Prepare the Crispy Onion Topping
In a small bowl, toss the 1 thinly sliced yellow onion with 2 tbsp cornstarch and 1 tbsp lemon juice. This coating ensures a crispy, golden finish. Heat ¼ cup extra-virgin olive oil in a large skillet over medium-high heat until shimmering.
Add the cornstarch-coated onions in a single layer, cooking undisturbed for 3-4 minutes until the edges turn golden brown. Stir gently to crisp all sides, then remove from heat. The onions should be crispy yet tender—if they darken too quickly, reduce the heat slightly next time.
Cook the Marinated Mushrooms
Preheat a large skillet over medium heat and remove the mushrooms from the marinade (reserve the marinade). Add the mushrooms to the skillet in a single layer, cooking for 4-5 minutes until they release their moisture and begin to brown. Pour the reserved marinade over the mushrooms, then reduce heat to low and simmer for 3-4 minutes, stirring occasionally, until the liquid reduces slightly and the mushrooms are tender.
Stir in the ¼ cup chopped fresh dill and cook for an additional 1 minute to infuse the mushrooms with freshness. The mushrooms should be glossy, smoky, and tender with a slight crispness at the edges.
Assemble and Serve
Transfer the marinated mushrooms to a serving platter and arrange them in an even layer. Sprinkle the crispy onions evenly over the top, pressing down gently to ensure they adhere. The contrast of the crispy onions with the tender, smoky mushrooms creates a satisfying texture.
Serve immediately while the onions are at their crispest. Garnish with additional chopped fresh dill if desired. This dish delivers the smoky, savory profile of traditional smoked salmon with a vegan twist, perfect for bagels, crackers, or as a standalone appetizer.
Pro Tips For Making Vegan Smoked Salmon
- Slice Mushrooms Evenly: I learned this the hard way—uneven slices mean some mushrooms stay tough while others turn mushy. Use a sharp knife and aim for ¼-inch thickness every time, or your dish will have a frustrating texture inconsistency.
- Reserve That Marinade: Pouring the marinade over the mushrooms in Step 3 isn’t just flavor—it’s moisture. Skimping here makes the mushrooms dry out fast. Strain it first if you’re picky about texture, but don’t skip it entirely.
- Onions Need Space: Crowd the onions in the pan, and you’ll end up with soggy rings instead of crispy crowns. Work in batches if needed—single layer only, and don’t stir until they’re golden. Patience here makes all the difference.
- Simmer Low and Slow: After adding the marinade, cranking the heat won’t caramelize the flavors—it’ll just burn the edges. Low heat for 3-4 minutes lets the liquid reduce gently, coating the mushrooms in that smoky-sweet glaze. Trust the process.
Make-ahead tips for leftovers
Marinate Overnight
The marinade works best when the mushrooms soak up the flavors for at least 4 hours, but honestly, I always marinate mine overnight—it’s like letting the mushrooms nap in a smoky spa.
This extra time deepens the umami and smoky notes, making the mushrooms taste even more like traditional smoked salmon. Just toss them in the fridge after mixing, and you’ll wake up to a dish ready to cook. 💫
Prep Onions Ahead
Slice your onions the night before and store them in an airtight container with a damp paper towel. This keeps them crisp until you’re ready to cook them. I like to prep everything the day before so I can focus on the final assembly when guests arrive.
The cornstarch coating can be mixed ahead too—just toss the onions with it and store them until cooking time.
Double the Marinade
If you’re making this for a crowd or meal prepping, double the marinade and store it separately. The mushrooms will absorb it perfectly even if you’re cooking them in batches.
I’ve found that the marinade keeps well for up to 5 days in the fridge, so you can use it for multiple meals. Just add a splash of water if it thickens too much.
Freeze for Later
For the ultimate convenience, freeze the marinated mushrooms before cooking. Spread them on a tray to freeze individually, then transfer to a freezer bag. When ready to cook, thaw them in the fridge overnight and proceed with the recipe.
The crispy onions are best made fresh, but you can freeze the mushrooms alone for up to 3 months. Reheat them gently in a skillet to restore their texture.
Assemble in Advance
If you’re serving this at a party or gathering, assemble the mushrooms and onions on the platter up to 2 hours ahead of time. Cover loosely with foil to keep them warm and crisp.
Just pop them in the oven at 300°F for 10 minutes before serving to reheat. This way, you can focus on other dishes while your vegan smoked salmon shines.

Frequently asked questions
Why does marinating overnight make a difference?
Marinating the shiitake mushrooms overnight lets them soak up the smoky flavors deeply, creating a richer taste similar to traditional smoked salmon. The liquid smoke, tamari, and maple syrup blend into the mushrooms fully, making them more flavorful and tender. It’s like giving them a spa treatment before cooking!
Can I use other mushrooms instead of shiitake?
While shiitake work best for their meaty texture, you can substitute cremini or oyster mushrooms in a pinch. Just note they’ll absorb flavors slightly differently, so marinating for 4 hours minimum is still key. The crispy onion topping remains the same—it’s the star texture contrast!
What if my crispy onions burn before they crisp up?
If the onions darken too quickly, lower the heat to medium and stir gently to distribute the oil. The key is to cook them in a single layer undisturbed for 3-4 minutes first. If needed, cover with a lid briefly to trap heat. Always use medium-high heat for the initial sear!
Can I make this dish ahead of time?
Marinate the mushrooms overnight and prep the onions the night before. Store them separately in the fridge. Assemble up to 2 hours ahead and reheat in a 300°F oven for 10 minutes before serving. The crispy onions stay best fresh, but the mushrooms reheat beautifully.
What’s the best way to reheat leftovers?
Gently warm the mushrooms in a skillet over low heat for 2-3 minutes to restore their texture. Avoid microwaving—they’ll turn soggy! If the onions lost crunch, crisp them again in a dry pan for 1 minute. A quick squeeze of lemon juice and fresh dill adds brightness.
