Bring a large pot of well-salted water to a boil. Cook the spaghetti until just shy of al dente. Reserve 1/4 cup of the pasta water, then drain.
Heat the oil in a large skillet over medium heat. Add the garlic and ginger. Cook for about 1 minute, stirring constantly, just until fragrant.
Stir in the chili oil and let it gently sizzle for 30 seconds to bloom the spices.
Pour in the coconut milk, soy sauce, vinegar, maple syrup, salt, and pepper. Whisk until smooth. Simmer for 3 to 4 minutes, until slightly thickened.
Add the drained spaghetti and reserved pasta water to the skillet. Toss well with tongs until the sauce fully coats the noodles and turns glossy.
Stir in the nutritional yeast. Toss again for 1 to 2 minutes, allowing the sauce to thicken and cling to the pasta.
Serve immediately topped with fresh herbs and sesame seeds. Enjoy!

Notes
Storage and ReheatingStore any leftover pasta inside an airtight container in the refrigerator for 3-5 days. While you can freeze the sauce for up to 3 months, I don’t recommend freezing the mixed pasta and sauce since the texture might change. You can reheat the dish on the stovetop or in the microwave. Stir gently so the oil sauce warms evenly. If it’s too dry, add some liquid to revive the texture.
