Place the raw cashews in a heatproof bowl and cover them with hot water. Let them soak for about 20 minutes to soften.
Drain and rinse the cashews before using. This helps create a smoother, creamier Alfredo sauce.
Step 2: Cook the Cauliflower

Bring a pot of water to a boil. Add the cauliflower florets and cook for 8–10 minutes, or until they are fork-tender.
Drain thoroughly and set aside. The cauliflower should be very soft so it blends easily.
Step 3: Cook the Pasta

Step 4: Make the Creamy Alfredo Sauce

Add the cooked cauliflower, soaked cashews, garlic, plant-based milk, vegetable broth, nutritional yeast, olive oil, lemon juice, onion powder, salt, black pepper, and Italian seasoning to a high-speed blender.

If the sauce is too thick, add a little more plant-based milk or reserved pasta water until you reach your desired consistency.
Step 5: Heat the Sauce
Pour the blended sauce into a saucepan over medium-low heat.
Stir gently for 3–5 minutes until warmed through. Avoid boiling the sauce vigorously.
