why mushroom & black pepper?

Mushrooms are the perfect stand-in for meat here (check out this article from Plant Based News) since their natural umami and chewy texture which make them ideal for soaking up the intense flavors of black pepper and soy. I love using a mix—shiitake for depth, oyster mushrooms for texture, and cremini or button mushrooms for accessibility.

But honestly, use whatever mushrooms you’ve got, because this recipe is forgiving.

Inspired by the black pepper sauces of East and Southeast Asia, this dish balances heat, soy, and earthiness with the juicy bite of mushrooms. The best part? It comes together in about 20 minutes and hits all the notes: smoky, spicy, salty, and slightly sweet.

ingredients

• 400g mushrooms (I use a mix of shiitake, king oyster, and shimeji mushrooms)
• 3 shallots (or 1 onion)
• 2 spring onions

Sauce ingredients:

• 2 tablespoon of soy sauce
• 1 tablespoon vegan oyster sauce
• 1 tablespoon rice vinegar
• 1 tablespoon sugar
• 1 tablespoon minced chilli
• 1 teaspoon black pepper

instructions

1. Prep the ingredients: Start by cleaning and slicing the mushrooms, then thinly slice the shallots (or oninon). Next, chop the spring onions and separate the white and green parts.
2. Make the sauce: In a small bowl, mix together the soy sauce, vegan oyster sauce, rice vinegar, sugar, minced chili and black pepper.
3. Sauté the aromatics:
   Heat a bit of oil in a pan over medium heat. Then add the sliced shallots and the white part of the spring onions. Cook until soft and fragrant—about 2-3 minutes.
4. Cook the mushrooms:
   Add the mushrooms to the pan. Stir-fry for 5–7 minutes, or until they’re golden and tender. After that let them sit undisturbed for a minute or two between stirs to get that beautiful caramelization.
5. Add the sauce:
   Pour in the sauce and toss well to coat. Let it simmer for another 2–3 minutes until the sauce thickens slightly and clings to the mushrooms.
6. Finish it off:
   Turn off the heat and toss in the green part of the spring onions.

It's always a good choice to server it hot over steamed rice and leafy greens whether you're preparing a lunch box or serving at home.

Top with extra chili if you're feelin’ spicy 🌶️.
