  • Pasta: Long pasta shapes like fettuccine, spaghetti, or bucatini work beautifully as they hold the creamy sauce well.
  • White Miso Paste (Shiro Miso): This is the secret weapon. It’s milder and slightly sweeter than other varieties, providing a perfect umami base without overpowering the dish.
  • Unsalted Butter: Adds richness and helps create that luscious, velvety texture.
  • Heavy Cream: This gives the sauce its decadent creaminess. For a lighter version, you can use half-and-half.
  • Garlic: Freshly minced garlic adds a fragrant, aromatic depth that complements the miso perfectly.
  • Starchy Pasta Water: The liquid gold of pasta making! It helps emulsify the sauce, making it cling to every strand of pasta.

How to Make The Perfect Miso Pasta Sauce

Follow these simple steps to create a flawless Miso Pasta Sauce every time. The key is to move quickly and use that starchy pasta water to bring it all together.

  1. Cook the Pasta: Bring a large pot of salted water to a boil. Add your pasta and cook according to package directions until al dente. Just before draining, reserve about 1 cup of the starchy pasta water.
  2. Start the Sauce: While the pasta is cooking, melt the butter in a large skillet or pan over medium heat. Add the minced garlic and cook for about 30-60 seconds until fragrant, being careful not to let it brown.
  3. Create the Miso Base: In a small bowl, whisk together the miso paste and about 1/4 cup of the hot pasta water until smooth. This prevents the miso from clumping when added to the pan. Pour the miso slurry into the skillet with the garlic butter and whisk to combine.
  4. Make it Creamy: Reduce the heat to low and slowly whisk in the heavy cream until the sauce is smooth and uniform in color. Let it gently simmer for 1-2 minutes to thicken slightly. Do not let it boil, as this can alter the flavor of the miso.
  5. Combine and Serve: Drain the cooked pasta and add it directly to the skillet with the sauce. Toss everything together, adding more reserved pasta water a tablespoon at a time, until the sauce coats the pasta beautifully. Serve immediately, garnished with toasted sesame seeds or fresh chives if desired.

Choosing The Right Miso

The type of miso you choose will have a big impact on the final flavor of your sauce. While there are many varieties, here are the most common ones you’ll find.

Look at that silky smooth umami pasta sauce!

White Miso (Shiro Miso)

This is the best choice for this Miso Pasta Sauce recipe. White miso is fermented for a shorter period, resulting in a mild, slightly sweet, and delicate flavor that enhances the sauce without overpowering it.

Yellow Miso (Shinshu Miso)

Yellow miso is a good middle-ground option. It’s fermented longer than white miso, giving it a slightly stronger, earthier flavor. It will still work well in this recipe if it’s all you have on hand.

Red Miso (Aka Miso)

Red miso has the strongest and most pungent flavor, as it’s fermented for the longest time. It’s wonderful in heartier dishes like stews and marinades but can easily dominate the other flavors in this delicate cream sauce. We recommend saving it for another use.

Tips for Unforgettable Miso Pasta

Want to take your Miso Pasta Sauce from great to absolutely divine? Here are a few expert tips to ensure success.

  • Don’t Skip the Pasta Water: This is the most crucial element for creating a silky, non-greasy sauce that clings perfectly to the pasta.
  • Never Boil Miso: High heat can destroy the delicate probiotics and nuanced flavors of miso. Always add it over low heat and keep the sauce at a gentle simmer.
  • Whisk the Miso First: Always make a slurry with the miso and hot water before adding it to the pan. This ensures a smooth, lump-free sauce.
  • Taste and Adjust: Miso paste is salty, so you likely won’t need to add much, if any, extra salt. Taste the sauce before serving and adjust if necessary.
