📝 About This Recipe

Experience the soul-soothing harmony of East-meets-West with this classic Yoshoku staple, where Italian al dente pasta is transformed by the deep, savory power of Japanese 'umami.' This dish features a medley of earthy forest mushrooms sautéed in golden butter and finished with a delicate soy-dashi glaze that clings to every strand. It is a sophisticated yet comforting weeknight masterpiece that highlights the Japanese philosophy of enhancing simple ingredients with refined techniques.

🥗 Ingredients

The Pasta

  • 200 grams Spaghetti (high-quality bronze-cut preferred)
  • 1 tablespoon Kosher Salt (for the boiling water)

Aromatic Base and Mushrooms

  • 2 tablespoons Unsalted Butter (divided into two 1-tbsp portions)
  • 1 tablespoon Olive Oil
  • 2 cloves Garlic (thinly sliced)
  • 100 grams Shiitake Mushrooms (stems removed and sliced)
  • 100 grams Shimeji or Enoki Mushrooms (bottoms trimmed and separated)
  • 2 slices Bacon or Pancetta (cut into 1-cm batons for smoky depth)

Wafu Sauce Liquid

  • 1.5 tablespoons Soy Sauce (Japanese dark soy sauce preferred)
  • 1 tablespoon Mirin (for a hint of sweetness)
  • 1/2 teaspoon Dashi Powder (instant kombu or bonito dashi)
  • 1/4 cup Pasta Cooking Water (reserved from the pot)

Garnish and Finishing

  • 1/2 sheet Nori (Seaweed) (shredded into fine strips (kizami nori))
  • 2 stalks Scallions (finely chopped on a bias)
  • 1 teaspoon Toasted White Sesame Seeds
  • 1 pinch Shichimi Togarashi (Japanese seven-spice for a kick of heat)

👨‍🍳 Instructions

  1. 1

    Bring a large pot of water to a rolling boil. Add the tablespoon of salt; it should taste seasoned like a light soup.

  2. 2

    Add the spaghetti to the boiling water. Cook for 1 minute less than the package instructions to ensure a perfect 'al dente' texture, as it will finish cooking in the pan.

  3. 3

    While the pasta cooks, heat the olive oil and 1 tablespoon of butter in a large skillet over medium heat.

  4. 4

    Add the bacon batons to the skillet. Fry until the fat has rendered and the edges are slightly crisp and golden.

  5. 5

    Toss in the sliced garlic. Sauté for about 30 seconds until fragrant, being careful not to let the garlic turn brown or bitter.

  6. 6

    Increase the heat to medium-high and add all the mushrooms. Sauté for 3-4 minutes without moving them too much at first to allow them to develop a deep, caramelized color.

  7. 7

    In a small bowl, whisk together the soy sauce, mirin, and dashi powder until combined.

  8. 8

    Just before draining the pasta, carefully scoop out 1/4 cup of the starchy pasta cooking water and set it aside.

  9. 9

    Drain the pasta and add it directly into the skillet with the mushrooms and bacon.

  10. 10

    Pour the soy-mirin mixture and the reserved pasta water over the noodles.

  11. 11

    Add the remaining 1 tablespoon of butter. Toss everything vigorously over medium heat for 1-2 minutes. The butter and starchy water will emulsify with the soy sauce to create a glossy, silk-like glaze.

  12. 12

    Taste a strand of pasta. If it needs more salt, add a tiny splash of soy sauce. If too dry, add another tablespoon of pasta water.

  13. 13

    Divide the pasta between two warmed bowls, ensuring the mushrooms and bacon are distributed evenly on top.

  14. 14

    Garnish generously with the shredded nori, chopped scallions, sesame seeds, and a dusting of shichimi togarashi for a professional finish.

💡 Chef's Tips

Always reserve more pasta water than you think you need; that liquid gold is the secret to a silky Wafu sauce. Don't wash your mushrooms with water; wipe them with a damp paper towel to prevent them from becoming soggy. Use a high-quality Japanese soy sauce (like Kikkoman or Yamasa) for the most authentic flavor profile. If you want a vegetarian version, omit the bacon and use a kombu-based dashi instead of bonito. Toasting your sesame seeds in a dry pan for 30 seconds before garnishing will unlock a much deeper nutty aroma.

🍽️ Serving Suggestions

Pair with a crisp, cold Japanese lager or a dry Ginjo Sake to cut through the richness of the butter. A side of Sunomono (Japanese cucumber salad) provides a refreshing acidity that balances the umami. Serve with a light Miso soup as a starter for a complete Yoshoku-style meal. For an extra indulgent touch, top the finished pasta with a single raw egg yolk or a soft-poached Onsen egg.
