Miso Mushroom Pasta with Cheese Tortellini

This creamy miso mushroom pasta with cheese tortellini is rich and savory without using cream, thanks to miso, broth, and cheese. A cozy vegetarian dinner for two.

This creamy miso mushroom pasta is rich and satisfying without feeling heavy, thanks to deeply browned mushrooms, white miso, broth, and cheese instead of cream. My husband and I both love mushrooms, and I’m always drawn to sneaking subtle Asian flavors into familiar Western dishes, like I do in my bok choy mushroom pasta, which is what inspired this recipe. I love serving it with refrigerated cheese tortellini for a cozy date-night-in feel, though the sauce works just as well with ravioli or short pasta. It’s quick and easy to make, yet feels special enough for a meat-free Valentine’s Day dinner for two.

Why This Miso Mushroom Pasta Works

• Deeply browned mushrooms create rich, savory flavor without meat
• White miso added at the end boosts umami without overpowering
• Creamy without heavy cream, thanks to broth, a light thickener, and cheese
• Ready in about 30 minutes, yet impressive enough for a date night at home

Ingredients You’ll Need

• Mushrooms: A mix of baby bella, beech, oyster, or shiitake works well. Browning them deeply is key to building flavor.
• Butter: Adds richness and helps brown the mushrooms and aromatics.
• Shallot: Softer and sweeter than onion, it gives the sauce a gentle base flavor (Substitute: about ¼ cup finely chopped yellow onion if needed).
• Garlic: Brings warmth and depth without overpowering the miso.
• Dried thyme: A subtle herbal note that pairs nicely with mushrooms.
• All-purpose flour: Lightly thickens the sauce without making it heavy.
• Dry white wine: Deglazes the pan and adds brightness. Use something drinkable (Substitute: use ¼ cup vegetable broth plus 1–2 teaspoons lemon juice if you don’t cook with wine).
• Vegetable broth: Forms the base of the sauce and keeps the dish vegetarian.
• Cheese tortellini: Makes the dish feel rich and special (Substitute: ravioli or short pasta like rigatoni, penne, or fusilli - about 4 to 6 oz dry pasta serves 2 people). 
• White miso paste: Adds savory depth and umami. Stirred in towards the end to keep the flavor balanced.
• Pecorino Romano or Parmesan:  Adds saltiness and helps finish the sauce smoothly.
• Black pepper: For gentle heat and balance.
• Fresh herbs (optional): Parsley or chives add freshness at the end.

How to Make Miso Mushroom Pasta

1. Cook the tortellini
   Cook the tortellini 1 minute shy of package directions. Drain and set aside. It may clump slightly, which is fine (the sauce will loosen it later).
2. Brown the mushrooms
   Melt butter in a wide skillet and cook the mushrooms in a single layer, avoiding frequent stirring, until deeply browned and most moisture has evaporated. Push the mushrooms to the edges of the pan.
3. Cook the aromatics in the center
   Add butter to the center of the pan, then add the shallot, garlic, and thyme. Cook until the shallot softens and turns translucent, then stir everything together.
4. Lightly thicken the base
   Sprinkle the flour over the vegetables, stir to coat evenly, and cook briefly to remove the raw flour taste.
5. Deglaze with wine
   Pour in the white wine and scrape up any browned bits. Let it reduce until nearly evaporated.
6. Build the sauce
   Add 1¼ cups vegetable broth and let the sauce simmer until it looks glossy and slightly thickened.
7. Finish cooking the pasta in the sauce
   Add the tortellini and cook briefly, tossing gently. This finishes cooking the pasta and further reduces the sauce.
8. Finish gently
   Lower the heat and stir in the loosened miso, cheese, and black pepper. Let everything meld for 1–2 minutes, then garnish with parsley and extra cheese before serving.

Tips for Best Results

• Don’t salt the mushrooms
  Cooking the mushrooms without salt helps them brown properly and build deeper flavor before any seasoning is added.
• Reduce the sauce before adding pasta
  Let the sauce thicken slightly first. Once the tortellini is added, it will continue reducing as the pasta finishes cooking.
• Expect the sauce to loosen, then thicken again
  Adding the miso–broth mixture introduces a bit more liquid, while the cheese helps bring the sauce back to a creamy consistency.
• Add miso gently
  Loosen the miso with warm broth and stir it in over low heat to keep the flavor balanced.
• Taste before adding salt
• This dish already has built-in seasoning from the miso, cheese, broth, and tortellini. Taste after adding the miso and cheese and adjust only if needed.
