  • Total Time: 30 minutes
  • Yield: 4 servings

Ingredients

Pasta

  • 8 ounces spaghetti

For Sautéing

  • 1 tablespoon avocado oil, or oil of choice
  • 1 tablespoon vegan butter
  • 5 ounces shiitake mushrooms, sliced
  • Sea salt and black pepper to taste
  • 4 cloves garlic, minced

Sauce

  • 3 tablespoons white miso
  • 1 to 1 ½ cups pasta water, start with 1 cup
  • ¼ cup vegan Parmesan cheese
  • 2 tablespoons fresh parsley, chopped (or herb of your choice)

Instructions

  1. Cook the Pasta: Prepare the spaghetti according to the package instructions in a large pot of well-salted boiling water. Once cooked to al dente, drain the pasta and set aside.
  2. Sauté Mushrooms: Heat half a tablespoon of avocado oil and the tablespoon of vegan butter in a large pan over medium-high heat. Add the sliced shiitake mushrooms, seasoning them lightly with sea salt and black pepper. Sauté until golden, about 5 to 8 minutes. Remove the mushrooms from the pan and set aside.
  3. Adjust Heat: Reduce the pan heat to medium-low and let it rest for 3 minutes to prevent burning the garlic and ensure the sauce doesn’t dry out.
  4. Sauté Garlic and Make Sauce: Add the remaining half tablespoon of oil to the pan. Add minced garlic and sauté for about 1 minute until fragrant. Stir in the white miso paste and begin adding the reserved pasta water starting with 1 cup while whisking until the miso dissolves completely and the sauce is smooth.
  5. Add Vegan Parmesan: Stir in the vegan Parmesan cheese to combine evenly into the sauce.
  6. Combine All Ingredients: Return the cooked pasta and sautéed mushrooms to the pan along with the chopped fresh parsley. Toss everything together gently until well mixed. Turn off the heat to avoid drying out the pasta.
  7. Adjust Sauce Consistency and Seasoning: If a creamier sauce is desired, gradually add more pasta water, two tablespoons at a time, until the preferred consistency is reached. Taste and adjust seasoning as needed with additional salt or pepper. Serve immediately and enjoy!

Notes

  • Use avocado oil or your preferred neutral oil to maintain the subtle flavors in the dish.
  • White miso works best for a delicate flavor; avoid stronger misos to keep the sauce balanced.
  • If vegan Parmesan is unavailable, nutritional yeast can be used as a substitute.
  • Reserve some pasta water before draining; it’s key for creating a smooth sauce that clings to the noodles.
  • Adjust the amount of pasta water to achieve your preferred sauce creaminess.
  • Feel free to swap shiitake mushrooms with cremini or button mushrooms if desired.
