Stepwise Method: Fettuccine Alfredo

Step 1: Prepare the Cauliflower
Start by bringing a large pot of salted water to a boil. Add the cauliflower florets and cook until tender, about 8-10 minutes. Drain the cauliflower, reserving about 1 cup of the cooking water.
Step 2: Make the Sauce
In a blender or food processor, combine the cooked cauliflower, Parmesan cheese, olive oil, garlic, Dijon mustard, butter, lemon juice, sea salt, and freshly ground black pepper. Blend until smooth and creamy. If the mixture is too thick, add some of the reserved pasta cooking water until desired consistency is reached.
Step 3: Cook the Fettuccine
In the same pot, cook the fettuccine according to package instructions until al dente. Drain, reserving some of the pasta water as mentioned earlier.
Step 4: Combine Pasta and Sauce
Return the drained fettuccine to the pot over low heat. Pour the cauliflower sauce over the fettuccine, tossing to coat the pasta evenly. If the sauce is too thick, add more reserved pasta water, a little at a time, until it reaches your preferred consistency.
Step 5: Serve
Serve the Fettuccine Alfredo immediately, garnished with additional Parmesan cheese and chopped fresh parsley for a pop of color.
Make It Year-Round

This Fettuccine Alfredo is perfect for every season. Here’s how to enjoy it year-round:
- Spring: Add fresh asparagus or peas for a burst of color and nutrition.
- Summer: Incorporate cherry tomatoes and basil for a refreshing twist.
- Fall: Mix in roasted butternut squash for added sweetness and warmth.
- Winter: Top with sautéed mushrooms for a hearty and comforting meal.
What Not to Do
Avoid these common pitfalls when preparing your Fettuccine Alfredo:
- Don’t overcook the cauliflower; it should be tender but not mushy.
- Avoid using pre-grated Parmesan, as it may not melt as smoothly into the sauce.
- Don’t skip reserving the pasta cooking water; it’s essential for adjusting the sauce’s consistency.
- Be cautious with the salt; the Parmesan can be quite salty on its own.
Save for Later: Storage Tips
If you have leftovers (though they might not last long), follow these tips to store your Fettuccine Alfredo:
- Store in an airtight container in the refrigerator for up to 3 days.
- Reheat gently on the stove, adding a splash of reserved pasta water or additional olive oil to loosen the sauce.
- For longer storage, freeze the sauce separately from the pasta and consume within a month.
