Cauliflower Alfredo Sauce
  • 8 ounces fettuccine pasta, about 1 inch in diameter
  • 1 tablespoon olive oil
  • pinch of salt
  1. Cook the fettuccine in salted boiling water for 10-12 minutes, until al dente. Drain into a colander, toss with 1 tablespoon olive oil, and set aside.

  2. Heat the coconut oil in a large pot over medium-high heat. Once melted, add onions and garlic. Cook, stirring occasionally, until onions are translucent, about 5 minutes.

  3. Add cauliflower florets and saute for another 2-3 minutes. Once slightly tender, add vegetable broth, cover and cook until cauliflower is soft all the way through, about 5 more minutes.
  4. Transfer to a high-speed blender and add remaining Alfredo Sauce ingredients. Blend until completely smooth. Set aside.
  5. Toss noodles with the Alfredo Sauce. Top with vegan parmesan, fresh parsley, and freshly ground pepper. Serve immediately.
