Tips and Tricks to making Mushroom Pasta with Soy Butter Garlic Sauce

  • You can replace any mushrooms for the oyster mushrooms but I recommend “meaty-er” mushrooms. My favourites are: shimeji mushrooms & portobello mushrooms

  • Slightly brown the mushrooms as it will bring out their flavour more

  • Dashi (Kombu stock) & Mirin can be found in asian grocery stores

  • Keep an eye on the sauce so it doesn’t burn when reducing it by mixing every couple of seconds

  • I highly recommend topping it off with some vegan parmesan that you can make by processing: 1/2 c roasted cashews, 2 tbsp nutritional yeast, 1/2 tsp garlic powder, 1/2 tsp onion powder & 1/2 tsp of salt

  • P.S. feel free to use this soy butter garlic sauce over rice, veggies and other protein sources!
