In a large pot, bring the vegetable broth to a boil. Add the cauliflower florets and cook until tender, about 8-10 minutes.
In a skillet over medium heat, add olive oil and sauté the minced garlic until fragrant, about 2 minutes. Be careful not to burn it.
Once the cauliflower is cooked, drain it and transfer it to a blender. Add the sautéed garlic, almond milk, nutritional yeast, onion powder, nutmeg (if using), salt, pepper, and lemon juice. Blend until completely smooth and creamy. Adjust the consistency with more almond milk if needed.
Cook the fettuccine pasta according to package instructions. Drain and set aside.
In a large serving bowl, combine the cooked pasta and the creamy cauliflower sauce. Toss until the pasta is well coated.
Taste and adjust seasoning if necessary.
Serve warm, garnished with chopped parsley for a fresh touch.
Notes
Adjust the consistency of the sauce with more almond milk if needed.
