In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onions along with a pinch of salt. Cook for approximately 10-15 minutes, stirring frequently, until the onions turn a beautiful golden brown and become caramelized.
Once the onions are perfectly caramelized, stir in the minced garlic and sauté for an additional 2 minutes, or until the garlic is fragrant and lightly golden.
Meanwhile, bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package instructions until al dente. Remember to reserve 1 cup of the starchy pasta water prior to draining the pasta. Set the drained pasta aside.
In the skillet with the caramelized onions and garlic, pour in the vegetable broth and canned coconut milk. Then, stir in the nutritional yeast, soy sauce or tamari, dried thyme, and season with salt and pepper. Mix well and let the sauce simmer for about 5-7 minutes, which will allow it to thicken slightly.
Add the freshly cooked pasta to the skillet and gently toss to thoroughly coat the pasta in the creamy sauce. If the sauce appears too thick, feel free to add a splash of the reserved pasta water to achieve your desired consistency.
Taste the dish and adjust the seasoning as needed, adding more salt, pepper, or a sprinkle of crushed red pepper flakes for an extra kick if desired.
Plate the creamy pasta evenly and garnish each serving with freshly chopped parsley for a vibrant touch.
Notes
For an appealing presentation, serve the pasta in shallow bowls and drizzle a little olive oil on top.
