This spinach and mushroom pasta is packed with large shiitake mushrooms, baby spinach, onion and garlic. It’s easy to whip up in less than 30 minutes, full of flavor and creamy without the use of cream!

This pasta dish is by far my favorite. It is easy to prepare, creamy but light and rich in vegetables.
The creamy sauce is made with soy milk, making it rich and satisfying yet lighter than regular white sauce. There’s a great mix of umami-rich flavors from the shiitake mushrooms, nutritional yeast and tamari soy sauce. Whether you choose long or short pasta, the result will be perfect and deliciously addictive!

Frequently asked questions
Nutritional yeast adds a nutty, savory, cheese-like flavor to the dish without using dairy. It has a lot of umami qualities, so it definitely adds a depth of flavor!
One thing about gluten-free spaghetti is that it tends to get soggy when even slightly cooked. Once drained with a sieve, I recommend rinsing them briefly under cold water to stop the cooking further, and a drizzle of oil to prevent them from sticking. Rinsing also helps reduce excess starch on the surface.
My favorite is shiitake mushrooms because they have so much umami flavor. However, you can switch to or mix different types like shimeji, portobello, or oyster.
