Start by finely chopping the onion and mushrooms.
1 large white onion, 400 g button mushrooms
Heat up 1 tbsp of olive oil to a large pan. Add the chopped onion with a pinch of salt. Let it cook for 5-8 minutes, until it starts to become golden.
Once the onion has softened, add the chopped mushrooms to the pan and cooked until they change colour and turn brown. Remove from the pan.
Cut the seitan into thin slices, to allow for better absorption of the flavors and more textures. Coat it in flour or cornstarch, this helps create a crisp, golden crust that enhances the overall texture.
200 g seitan
Add 2 tbsp of olive oil to the pan. Add the seitan and cook it until it start to develop a golden-brown crust then flip the slices. This process adds a delicious crispy bite.
Once the seitan is golden brown on both sides, add the mix of mushrooms and onions, and add the white wine. The wine adds depth and complexity, but if you prefer a non-alcoholic alternative, vegetable broth with a touch of lemon juice or vinegar can be used instead. Let it cook until the wine evaporates.
3/4 cup white wine
For the sauce, add soy milk mixed with soy sauce. This step allows the sauce to thicken and become rich and creamy.
1 cup soy milk, 1 tsp soy sauce
Let it to cook on low until it reaches the desired consistency—thick enough to coat the ingredients.
