Miso Butter Pasta is a fun twist on your usual pasta dish! It combines creamy butter with the rich, salty flavor of miso, creating a delightful sauce that clings to every noodle.
This meal is super quick to whip up, perfect for those busy nights. I love tossing in some veggies or protein to make it extra tasty. Trust me, you’ll be making this again and again! 🍝
Key Ingredients & Substitutions
Pasta: You can use spaghetti or linguine for this dish, but any long pasta works. If you want a gluten-free option, try gluten-free spaghetti, or even zucchini noodles for a lighter version.
Miso Paste: White or yellow miso is perfect for a milder flavor. If you’re looking for a substitute, tahini mixed with a bit of soy sauce can mimic the creaminess. Just adjust to taste as tahini is richer.
Mushrooms: Cremini or button mushrooms add a nice depth. If you prefer a different flavor, shiitake mushrooms would be a great alternative. Dried mushrooms rehydrated in warm water also work well.
Spinach: Fresh spinach wilts beautifully, but if you have cooked spinach or kale, those can work too. Just skip the wilting step!
Butter: For a vegan option, replace the butter with a vegan butter or olive oil. It may change the texture slightly, but still delicious.
How Can I Make a Creamy Miso Butter Sauce?
The sauce is the star of this dish! Start by melting the butter and combining it with miso paste mixed with pasta water. This technique creates a smooth, creamy sauce.
- Heat olive oil and sauté the mushrooms until tender.
- Add garlic and cook briefly to enhance the flavor.
- Reduce heat, then mix in butter until it melts.
- Whisk miso paste with reserved pasta water separately, then add it to the skillet to create your sauce.
Remember to toss the pasta gently into the sauce for even coating. This step makes all the difference in achieving creamy goodness!

How Much Time Will You Need?
This delicious Miso Butter Pasta can be prepared in about 20 minutes. You’ll need around 10 minutes to cook the pasta and 10 minutes to prepare the sauce and combine everything. It’s quick and perfect for a busy weeknight dinner!
Step-by-Step Instructions:
1. Cook the Pasta:
Start by bringing a large pot of salted water to a boil. Once boiling, add the pasta (spaghetti or linguine) and cook it according to the package instructions until it’s al dente. Don’t forget to reserve about 1/4 cup of the pasta cooking water before you drain the pasta.
2. Sauté the Mushrooms:
While your pasta is cooking, heat the olive oil in a large skillet over medium heat. Add the sliced mushrooms and sauté them for about 5-7 minutes until they are tender and slightly browned. Stir occasionally to ensure they cook evenly.
3. Add Garlic and Butter:
Once the mushrooms are ready, add the minced garlic to the skillet. Cook for another minute until you can smell the garlic’s delicious aroma. Then, reduce the heat to low and stir in the unsalted butter until it melts smoothly into the mushroom mixture.
4. Combine Miso with Pasta Water:
In a small bowl, mix the miso paste with the reserved pasta cooking water until it’s smooth. This is going to help make your sauce creamy!
5. Make the Creamy Sauce:
Add the miso mixture to the skillet with the mushrooms and butter. Stir well to combine everything, creating a lovely creamy sauce.
6. Add the Pasta and Spinach:
Now it’s time to bring everything together! Add the cooked pasta to the skillet and toss it well, making sure the pasta is coated evenly with the miso butter sauce. Then, toss in the fresh spinach leaves and cook for an additional 1-2 minutes until the spinach wilts.
7. Season and Serve:
Finally, season your dish with salt and freshly ground black pepper to taste. Serve immediately while it’s warm, and if you like a little heat, sprinkle some chili flakes or shichimi togarashi on top for an extra kick!
Enjoy your flavorful, creamy Miso Butter Pasta!
Can I Use Different Types of Pasta?
Absolutely! While spaghetti or linguine works great, you can use any long pasta. For a gluten-free option, gluten-free spaghetti will also do nicely. Even zucchini noodles can be a fun, low-carb alternative!
What If I Don’t Have Miso Paste?
If you’re out of miso paste, you can substitute it with tahini mixed with a bit of soy sauce for a similar creamy texture and flavor. Just adjust the amount to suit your taste!
Can I Make This Dish Vegan?
Of course! Simply replace the unsalted butter with vegan butter or a splash of extra olive oil to keep it vegan-friendly. The dish will still be creamy and delicious!
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 2-3 days. To reheat, gently warm in a skillet over low heat, adding a splash of water or vegetable broth to help refresh the sauce.
