🥛Ingredients
Sauce

- homemade onion koji : It's a key part of this pasta dish. Onion koji is a seasoning that can be used in place of consommé. It takes a few days, but it's actually pretty simple to make. Just mix onions, salt, and raw rice malt well, put it in a glass jar, and let it sit at room temperature for one week in summer and two weeks in winter. If you want more details, check out how to make onion koji. It's a great vegan seasoning to keep in your kitchen to add variety to your vegan dishes. You can use it to make Vegan Bolognese, instant cup soup, vegan Japanese curry and more!
- rice koji miso: I prefer to use rice miso with a higher ratio of koji because it has a sweeter taste. That'll help the sauce have enough umami flavor.
- rice flour: I use rice flour to make the sauce thicker. It's a lot easier than making the sauce with wheat flour, and it's pretty much guaranteed to turn out right.
- plain soy milk: You can also use sweetened soy milk. Just adjust the amount of miso you add so the sauce doesn't end up too sweet.
- olive oil: I like to use olive oil, but you can use any other oil that doesn't have a strong flavor, like rice bran oil.
- girlic: I prefer having some garlic in the creamy sauce, but you can leave it out if you prefer!
- black pepper: I like to add a bit of ground black pepper to the sauce for some extra flavor.
- spaghetti: You can choose any spaghettie you like.
Vegetables
- maitake mushrooms: Maitake mushrooms are a must-have ingredient. Maitake mushrooms are especially good with soy milk cream sauce, and they give the sauce a deep flavor. The sauce with and without maitake mushrooms will taste totally different, so please try making it with them.
- broccoli: To make this pasta more hearty, I always add it, but you can use asparagus instead or leave it out if you want.
- lotus root: I like to add it to add some texture, but it's totally up to you.
- spinach: Spinach is always a great choice with creamy sauce!

🔪Instructions
Before we get started, I've got a few tips for making creamy pasta.
Tips
The key to making this pasta is to make the cream sauce and boil the pasta at the same time. The reason for doing it at the same time is that the pasta cooking water is used to make the sauce.
It might keep you a little bit busy. But, there are some benefits for that.
First, you don't have to worry about the noodles stretching because of the pre-cooking. Second, when everything goes smooth, you can enjoy your delicious pasta hot right away.
Let's get started!
1. Make sauce mixture

Put the onion koji, miso, and rice flour in a small bowl and dissolve well with a small amount of soy milk. Then, just combine it with the rest of the soy milk and mix it all together.
⏰Start boiling water at the same time.
2. Make sauce

1)First, cut the vegetables into bite-size pieces.
⏰When the water comes to a boil, add salt and start boiling the pasta.
2)When the pasta starts to cook, sauté the garlic, maitake mushrooms, and lotus root in a pan with olive oil. When the veggies are lightly cooked, add the pasta cooking water and stir-fry.
3)When the liquid's all gone, turn off the heat and add the soy milk cream sauce base, then mix it all together. Then, heat it up again and cook it, stirring with a spatula, until it gets thicker.
3. Boil

When the pasta is 1 minute and 30 seconds from being done, add the broccoli and boil together before draining in a colander.
4. Toss

Finally, toss the spaghetti with the soy cream sauce!
