Ingredients
- 200 g spaghetti
- 100 g pine mushrooms
- 100 g fresh shiitake mushrooms
- 1/2 red bell pepper
- 1/2 yellow bell pepper
- 1/2 green bell pepper
- 2 tbsp olive oil
- 1 tsp salt
- 2 tsp freshly ground black pepper
- 1 tbsp vegan oyster sauce
- 2 tbsp pasta water
Instructions
- 1Boil the spaghetti

Once the water comes to a boil, add a spoonful of salt, then add the spaghetti. Boil for about eight to nine minutes until cooked through.
Tip: Adding salt to the water helps season the pasta from the inside as it cooks. - 2Prepare the pine mushrooms

Take the prepared pine mushrooms and carefully slice them into uniform pieces on a wooden cutting board.
Tip: Keep the slices consistent in thickness so they cook evenly. - 3Prepare the shiitake mushrooms

Slice the fresh shiitake mushrooms into pieces on a wooden cutting board to prepare them for stir-frying.
Tip: Ensure the shiitake mushrooms are cleaned before slicing. - 4Prepare the bell peppers

Take the red and yellow bell peppers and cut them into thin, uniform strips on a wooden cutting board.
Tip: Removing the seeds and white pith from the peppers ensures a better texture. - 5Drain the spaghetti

Once the spaghetti is cooked, use chopsticks to lift it from the pot, allowing the excess water to drain, and set it aside in a bowl.
Tip: Draining the pasta well prevents the stir-fry from becoming too watery. - 6Sauté the mushrooms

Heat the pan, add a little olive oil, and start by sautéing the sliced mushrooms over high heat for about three minutes until they turn golden brown.
Tip: Sautéing over high heat helps the mushrooms develop a nice, golden crust. - 7Stir-fry bell peppers

Add the prepared red, yellow, and green bell pepper strips to the pan with the golden brown mushrooms. Stir-fry everything evenly until the peppers are just tender.
Tip: Keep the heat high to ensure the bell peppers retain their vibrant color and slight crunch. - 8Incorporate the spaghetti

Add the previously cooked and drained spaghetti into the pan with the sautéed mushrooms and bell peppers. Combine them thoroughly over heat to integrate the flavors.
Tip: Tossing the pasta quickly ensures it coats well with the oil and aromatic mushrooms. - 9Season with salt

Add a teaspoon of salt to the spaghetti and vegetable mixture in the pan. Distribute the salt evenly to enhance the natural flavors of the ingredients.
Tip: Be careful with the amount of salt, especially if your vegan oyster sauce or soy sauce is already salty. - 10Add black pepper

Add a generous amount of freshly ground black pepper to the dish. This provides the signature spicy, aromatic kick to the Black Pepper Mushroom Spaghetti.
Tip: Freshly ground pepper is highly recommended over pre-ground for a much more potent and fragrant flavor. - 11Add vegan oyster sauce

Drizzle a fair amount of vegan oyster sauce over the spaghetti. If you dont have vegan oyster sauce, you can substitute it with a high-quality soy sauce.
Tip: Adding the sauce directly to the hot pan helps caramelize it slightly, deepening the umami profile. - 12Adjust consistency

Pour a small amount of pasta water or plain water into the pan. This helps create a light sauce that coats the spaghetti perfectly, preventing it from drying out.
Tip: Pasta water is ideal because its starch content helps thicken the sauce and bind it to the noodles. - 13Toss and serve

Quickly toss all the ingredients together over medium-high heat until the spaghetti is evenly coated with the black pepper and mushroom sauce. Serve immediately.
Tip: Keep the heat medium-high while tossing to ensure everything is hot and the sauce emulsifies slightly.
