Even as a food blogger, I’m not up for cooking an elaborate meal every night. But I don’t want to rely on takeout or store-bought frozen meals either. For those times when I want to cook something quick and simple, pasta is my go-to—and this miso butter pasta is my current favourite. Miso butter pasta is a Japanese-inspired dish that combines the slightly sweet, umami flavor of miso paste with creamy butter and noodles. The result is an incredibly rich and savoury dish that’s packed with flavor. Think of it as an elevated version of that comfort food favourite, buttered noodles. And, as promised, miso butter pasta is also ridiculously easy to make. You need just a few ingredients and a few minutes of cooking time. It takes about as long as making a box of vegan mac and cheese!

Notes on Ingredients
Scroll down to the recipe card to find the ingredient quantities and recipe instructions.
Spaghetti – Another long pasta would work too. Avocado oil – Or another neutral-flavoured oil. Vegan butter – Use your favourite store-bought brand or my homemade vegan butter. Shiitake mushrooms – Be sure to discard the tough stems. Sea salt and black pepper Garlic White miso – White miso has a delicate, mild flavour, with a lovely sweetness. It’s also labeled as shiro miso. Pasta water Vegan Parmesan – Use store-bought or homemade vegan Parmesan. Fresh parsley – Or herb of your choice.
What If I Forgot to Save the Pasta Water?
It happens to the best of us! If you accidentally drain all the water from the pasta, you can whisk 1/4 teaspoon of cornstarch with a cup of water and microwave it for a minute or two. Whisk again and use it in place of the pasta water.
How to Make Miso Butter Pasta
Ready for an easy weeknight dinner? Let’s go! Cook the pasta. Prepare the pasta according to the instructions on the box. Reserve a cup of the water, then drain. Melt the butter with the oil. Heat the oil and vegan butter in a large skillet set over medium-high heat. Cook the mushrooms. Add the mushrooms to the pan and cook for 5 to 8 minutes, or until they’re golden. Season with salt and pepper, then transfer the mushrooms to a plate or bowl. Reduce the heat. Lower the heat to medium-low and wait for 3 minutes for the skillet to cool. Start the sauce. Add the garlic to the skillet and sauté for about 1 minute, then whisk in the miso and pasta water until the miso is dissolved. Stir in the vegan Parmesan. Finish. Add the pasta, mushrooms, and parsley to the skillet. Toss to coat and turn off the heat. Season to taste and serve.
Tips for Success
These tips and hints will help you make sure your miso butter pasta turns out perfect:
Make sure you use the correct type of miso paste. There are different types of miso paste available, and some are bolder and saltier than white miso. Sweet, mild white miso is key to the flavour of this dish. Don’t overcook the garlic. The garlic should be cooked to give the sauce a nice flavor, but not so much that it burns or becomes bitter. Add the pasta water gradually. The pasta water helps create a creamy sauce thanks to its starch content. Add it in slowly and whisk until you achieve your desired consistency. Adjust the amount of pasta water as needed. You can add more pasta water 2 tablespoons at a time until you have a creamy sauce that evenly coats the spaghetti.
Serving Suggestions
Serve miso butter pasta alongside a simple salad or with a side of Roasted Garlic Bread or Garlic and Rosemary Focaccia Bread. It’s also great with Balsamic Roasted Vegetables.
Variations
Instead of shiitake mushrooms, you can use cremini mushrooms, white mushrooms, or a wild mushroom mix. Not a fan of mushrooms? Zucchini or summer squash, eggplant, fresh corn, and leeks are all delicious in miso butter pasta.
How to Store Leftovers
Refrigerate leftover miso butter pasta in an airtight container for up to 3 days. Reheat in the microwave or stovetop with a splash of water or broth until warmed through.
Can This Recipe Be Frozen?
Yes, you can freeze miso butter pasta for up to 3 months. To serve, thaw the noodles in the refrigerator overnight and then heat according to the instructions above.
