Why You’ll Love This Miso Butter Pasta Recipe

What really draws me to this Miso Butter Pasta Recipe is the way the miso paste adds this wonderful savory depth that elevates the dish beyond your everyday pasta.

I guarantee it’ll become a favorite in your rotation too.

Ingredients You’ll Need

All you need to make this dish is a handful of simple, wholesome ingredients that you probably already have or can easily get. Each ingredient plays a vital role in building the flavor, texture, and color of the pasta, making the whole experience deeply rewarding.

• Spaghetti (8 ounces): The perfect canvas that holds the sauce beautifully without overpowering the flavors.
• Avocado oil (1 tablespoon): I prefer this for its mild taste and high smoke point, but you can use your favorite cooking oil.
• Vegan butter (1 tablespoon): Brings that creamy, buttery goodness which is key for the sauce’s richness.
• Shiitake mushrooms (5 ounces, sliced): These add a meaty, earthy flavor that complements the miso nicely.
• Sea salt and black pepper: Essential for seasoning to balance and enhance all the flavors.
• Garlic cloves (4, minced): The aromatic backbone that gives the sauce a warm, inviting taste.
• White miso (3 tablespoons): The star ingredient that infuses the pasta with a deep, savory umami flavor.
• Pasta water (1 to 1 ½ cups): This starchy water helps create a silky, cohesive sauce.
• Vegan Parmesan cheese (¼ cup): Adds a subtle salty, cheesy note enhancing the dish’s creamy texture.
• Fresh parsley (2 tablespoons, chopped): A burst of freshness and color that brightens the final dish.

Directions

Step 1: Start by cooking the spaghetti according to the package instructions in a large pot of well-salted water. Once al dente, drain the pasta but reserve about a cup of the pasta water to help make the sauce later.

Step 2: Heat half a tablespoon of avocado oil and the full tablespoon of vegan butter in a large pan over medium-high heat. When hot, add the sliced shiitake mushrooms and sauté them until they turn golden brown, about 5 to 8 minutes. Season lightly with sea salt and black pepper, then remove the mushrooms from the pan and set them aside.

Step 3: Turn the heat down to medium-low and allow the pan’s temperature to drop for around 3 minutes. This step is crucial because it prevents the garlic from burning and keeps the sauce from drying out.

Step 4: In the remaining half tablespoon of oil, add the minced garlic and sauté for about 1 minute until fragrant. Then, whisk in the white miso paste along with 1 cup of the reserved pasta water. Keep whisking until the miso dissolves completely and the sauce becomes smooth and combined.

Step 5: Stir in the vegan Parmesan cheese, mixing well to incorporate it fully into the sauce.

Step 6: Add the cooked spaghetti, the sautéed mushrooms, and the chopped fresh parsley to the pan. Toss everything together gently to coat the pasta evenly with the sauce. Be careful not to overheat the pan here or the pasta might dry out. If you want a creamier consistency, add pasta water a little at a time, about 2 tablespoons, until you reach your preferred texture.

Step 7: Taste the pasta and adjust the seasoning with more salt or pepper as needed. Serve immediately and enjoy every flavorful bite!

Servings and Timing

This recipe makes 4 generous servings, perfect for sharing with family or friends. The prep time is super quick at only 5 minutes, while the cook time comes in around 25 minutes, bringing your total to about 30 minutes. There’s no additional resting or cooling time needed, so you can plate up and serve right away while it’s warm and fresh.

How to Serve This Miso Butter Pasta Recipe

When I serve this Miso Butter Pasta Recipe, I like to keep things simple but thoughtful. It pairs beautifully with a crisp, green salad or some roasted vegetables to balance out the richness of the sauce. Lightly dressed arugula or a cucumber salad with a lemon vinaigrette adds a refreshing contrast that I always appreciate.

For garnishing, I sprinkle extra chopped fresh parsley on top for a pop of vibrant color and a bit of freshness. Sometimes, I add a pinch of crushed red pepper flakes for a slight kick, which livens up the earthy flavors wonderfully. Drizzling a little more vegan Parmesan or a dusting of toasted sesame seeds can bring additional texture and flavor layers that really impress guests.

In terms of drinks, I enjoy accompanying this dish with a chilled glass of Sauvignon Blanc, which offers zesty acidity and herbaceous notes that cut through the buttery umami. If you prefer something non-alcoholic, a sparkling yuzu soda or green tea lemonade makes a refreshing match. This meal works perfectly for casual weeknight dinners, laid-back gatherings, or even a cozy date night at home. Always serve it warm for the best experience, and don’t be shy about generous portions because everyone ends up asking for seconds!

Variations

I love how flexible this Miso Butter Pasta Recipe is, allowing for plenty of creative twists. For example, swapping shiitake mushrooms with cremini or portobello mushrooms works beautifully and changes the texture slightly. You can also toss in some steamed broccoli or snap peas for extra crunch and nutrition.

If you’re gluten-free, I recommend using a gluten-free spaghetti or rice noodles — they hold up surprisingly well with this sauce. For friends who prefer vegan variations without butter, using just oil works, but I find vegan butter gives a creamier, more indulgent result. To switch up the flavor profile, try mixing in a small dollop of tahini for nuttiness or a pinch of smoked paprika for warmth.

Cooking methods can be adapted too: I sometimes roast the mushrooms in the oven with a drizzle of oil and salt for deeper flavor before tossing them with the pasta. Overall, this recipe is a fantastic base to experiment with whatever ingredients or flavors you love most.

Storage and Reheating

Storing Leftovers

When I have leftovers, I store them in airtight containers in the refrigerator. I find glass containers with tight-fitting lids work best to keep the pasta fresh without absorbing odors. The leftovers will keep well for up to 3 days. You might notice the sauce thickens in the fridge, which is totally normal.

Freezing

I personally don’t recommend freezing this Miso Butter Pasta Recipe because the creamy sauce can separate when thawed, resulting in a less pleasant texture. However, if you do want to freeze it, place it in a freezer-safe airtight container and use within 1 month. To maintain quality, thaw in the fridge overnight before reheating gently.

Reheating

The best way I’ve found to reheat this pasta is on the stovetop over low heat. Add a splash of water or vegan milk while warming it to help loosen the sauce and bring back the creaminess. Avoid microwaving if possible, as it tends to dry out the pasta and change the texture. Stir gently and heat just until warmed through for the tastiest results.

FAQs

Can I use other types of pasta for this recipe?

Absolutely! While spaghetti works beautifully, feel free to use fettuccine, linguine, or even short pasta like penne or rigatoni. The sauce clings well to many shapes, so pick your favorite or whatever you have on hand.

Is white miso the only kind of miso I can use?

White miso is ideal here because it’s mild and slightly sweet, complimenting the buttery sauce nicely. However, you can experiment with red or yellow miso for a stronger, earthier flavor — just use a bit less initially and adjust to taste.

Can I make this recipe without vegan cheese?

Yes, you can omit the vegan Parmesan if needed. The dish will still be tasty due to the miso’s umami and the buttery sauce, but the cheese adds a lovely salty layer. You can also try nutritional yeast as a cheesy alternative.

How do I make this dish more protein-rich?

Adding tofu cubes or cooked edamame works great for boosting protein without overpowering the dish. You could also stir in some toasted nuts like cashews for added texture and nutrition.

Can this recipe be made oil-free?

I find a little fat is essential for flavor here, but you could try substituting the oil and vegan butter with a small amount of vegetable broth or water, though the sauce might be less rich. Experiment and adjust seasonings to keep it flavorful.

This Miso Butter Pasta Recipe has won a permanent spot in my kitchen because it delivers on every level — flavor, ease, and flexibility.
