Vegan Char Siu Oyster Mushrooms: Crispy Chinese-Style Recipe

These Chinese-style char siu fried oyster mushrooms are a delicious, umami-packed vegan alternative to char siu pork. A simple homemade char siu-style marinade soaks into pearl oyster mushrooms, then quick pan-frying caramelises the sugars for crispy, sticky edges and an intensely savory finish. The dish is gluten-free, dairy-free and soy-free options are possible, and it pairs beautifully with seasoned sushi rice and a bright quick-pickled salad to balance the richness.

After living in Singapore for several years my family grew fond of char siu pork. When I became vegan, I wanted a version I could eat alongside them. These char siu oyster mushrooms quickly became a favorite: they deliver the familiar Chinese flavours and a meaty texture without the meat. The kids even ask for them at family meals, and at parties friends are often surprised they’re vegan.

Why you will love this Chinese fried oyster mushroom recipe

• These vegan char siu oyster mushrooms have a satisfying meatiness and absorb the classic sweet-savory char siu flavours without any meat.
• They are crispy and light at the edges while remaining tender inside, making them addictive finger food.
• Frying caramelises the sugars in the marinade, creating a crisp, sticky crust that intensifies umami notes.
• The sweet, sticky marinade contrasts beautifully with the zesty pickled salad, cutting through richness and keeping the dish balanced.
• Quick and easy: whisk the marinade, toss the mushrooms, marinate for an hour, then fry for a few minutes per side.

Why use oyster mushrooms?

Pearl oyster mushrooms have a soft but slightly chewy texture that soaks up marinades very well and mimics a meaty bite. They’re ideal for this recipe. If you need more protein or prefer a different texture, pressed firm tofu (marinated and fried) is a suitable alternative. Avoid small button or chestnut mushrooms here, as they won’t absorb flavours in the same way.

How to prepare oyster mushrooms

Cleaning

Don’t soak mushrooms. Wiping them with a damp cloth or brushing off dirt with a pastry brush preserves texture and prevents sogginess.

Prepping

If mushrooms come in a cluster, trim them from the main stem and remove any tough, woody pieces. Pearl oysters can usually be used whole; very large king oyster mushrooms should be sliced lengthwise so they absorb marinade and cook evenly.

Main ingredients

Char Siu Mushrooms

• Oyster mushrooms – Pearl oyster mushrooms are preferred for their size and texture. If using king oyster mushrooms, slice them lengthways first.
• Hoisin sauce – Use a gluten-free hoisin if required; homemade hoisin works well.
• Tamari – A naturally gluten-free soy alternative; coconut aminos can be used for a soy-free option.
• Rice vinegar – Can be substituted with apple cider or white wine vinegar if needed.
• Coconut sugar or brown rice syrup – Adds sweetness. Maple syrup or dark brown sugar are suitable swaps.
• Chinese five-spice powder – Provides the characteristic aromatic note.
• Garlic powder – Or use fresh garlic cautiously to avoid burning during frying.

Pickled Salad

• Carrot, cabbage, red onion – Julienned or shredded to maximize surface area for the pickling liquid. Cucumber can be added but should be salted and drained first to remove excess water.
• Pickling juice – Rice vinegar mixed with a pinch of salt and a dash of maple syrup or brown rice syrup brightens the vegetables and balances the dish.

How to make this recipe

This recipe is straightforward. The pickled salad and mushrooms benefit from an hour or more of resting, so start ahead if you can. When you’re ready to serve, the mushrooms cook in minutes.

Shred the carrots and cabbage and thinly slice the red onion. Mix the rice vinegar, salt and maple or brown rice syrup, pour over the vegetables, stir well and refrigerate, covered, while they pickle.

Whisk the marinade ingredients together and pour over the cleaned, separated oyster mushrooms. Gently mix so every piece is coated, cover and refrigerate to marinate for at least an hour (up to 4 hours if you have time).

Cook sushi rice according to packet instructions if serving with rice. Heat a neutral oil in a frying pan over medium-high heat. Using a slotted spoon, transfer marinated mushrooms to the hot pan in a single layer (work in batches if needed). Fry about 1–2 minutes per side until deeply caramelised and crisp. Drain each batch briefly on paper towel while you finish cooking.

Serve the mushrooms with sushi rice and pickled vegetables, finishing with a sprinkle of sesame seeds.

Knife skills

For the pickled salad, cut vegetables into thin matchsticks (julienne) so they absorb the pickling liquid quickly. A julienne peeler makes this fast, but you can also peel thin sheets and slice them into matchsticks by hand. For cabbage, peeling or thinly slicing a wedge works well. For red onion, halve, trim the top, peel and slice thinly from top to root.

Serving suggestions

These bold-flavoured mushrooms are lovely in small portions as an amuse-bouche or starter, served with sushi rice and pickled salad. They also work as part of a main course—marinate tofu the same way and fry or air-fry it alongside the mushrooms, or add them to a noodle stir-fry for a satisfying meal.

Making ahead, leftovers and storage

You can prepare the pickled salad and marinate the mushrooms up to a day ahead. Keep both refrigerated. Leftover salad keeps for a few days and can be added to other salads or stir-fries.
