Cauliflower Alfredo: A Healthier Twist on a Classic

Alfredo sauce, a beloved pasta staple, gets a healthy makeover! Whether
paired with fettuccine, chicken, or shrimp, Alfredo is a crowd-pleaser. This
cauliflower version mimics the look, smell, and taste of Alfredo, offering a
flavorful experience without the usual richness.

This recipe is a healthy alternative to traditional Alfredo, which is
typically loaded with cream, butter, and Parmesan cheese. This version uses
cauliflower, blended until smooth. This results in a near-perfect Alfredo
sauce with significantly fewer calories (only 111 per generous ½ cup serving!).

The flavor profile is still exceptional. Garlic sautéed in butter and olive
oil forms the base, which is complemented by the creamy puree of cauliflower
blended with milk, Parmesan cheese, pepper, and a touch of nutmeg.

Another great thing about this sauce is that it reheats beautifully. Unlike
classic Alfredo, which can separate and become greasy when reheated, this
cauliflower version maintains its consistency. It can be refrigerated or even
frozen without any issues.

Ingredient Notes

• Cauliflower: Look for a fresh, two-pound head. Remove outer leaves,
  rinse, and cut into florets. Pre-cut florets are a great time-saver.
• Milk: Any type of milk works, but whole or 2% milk will provide the
  richest flavor. While skim milk can be used, it may result in a slightly
  watery sauce.
• Unsalted butter and olive oil: Combining butter and oil adds depth to
  the flavor. You can use all butter or all olive oil if you prefer.
• Garlic: Finely mince a few fresh garlic cloves, or use a garlic press.
  Adjust the quantity according to your taste.
• Grated Parmesan cheese: For the smoothest sauce, grate the Parmesan
  yourself. Pre-grated Parmesan from a can will work, but it may not melt as
  well.
• Kosher salt and coarse ground pepper: Freshly ground black pepper is
  recommended for the best flavor.
• Nutmeg: Freshly grated nutmeg offers the best flavor, but ground nutmeg
  can be used.
• Parsley: This is an optional garnish that adds a fresh touch.
• Cooked pasta: Fettuccine is the classic choice, but feel free to use
  your favorite type of pasta.

How to Make Cauliflower Alfredo Sauce: Step-by-Step

Cook the cauliflower. Bring a large pot of water to a boil over high
heat. Add the cauliflower florets and boil for about 15 minutes, or until very
tender. Drain well.

Cook the garlic. While the cauliflower is cooking, melt the butter and
oil in a skillet over medium-low heat. Sauté the garlic for 2-3 minutes, until
soft and fragrant. Scrape the garlic mixture into the blender.

Blend. Transfer the drained cauliflower to the blender with the garlic
mixture. Add salt, pepper, nutmeg, and milk. Blend until completely smooth. A
high-powered blender is ideal, but a food processor can also be used. Scrape
the sides as needed.

Add cheese. Stir in the grated Parmesan cheese. If the sauce seems too
thick, add a little more milk.

Finish. Toss the cauliflower Alfredo sauce with cooked pasta. Add fresh
chopped parsley and more Parmesan cheese, if desired. Serve immediately.

Tips and Variations

• Don’t brown the garlic. Gently heat the garlic to bring out its
  flavor, avoiding burning it, which can give the sauce a sharp taste.
• Blend thoroughly. Blending the sauce very well is key to achieving
  the smooth, rich texture of classic Alfredo.
• Make it dairy-free. For a vegan version, substitute the Parmesan with
  nutritional yeast, use plant-based butter, and an unsweetened plant milk.
• Add sun-dried tomatoes. Blend a handful of sun-dried tomatoes into
  the sauce for extra flavor.

Serving Suggestions

• Chicken Add slices of
  air fryer chicken breasts
  to the top of the pasta.
• Shrimp Combine
  shrimp Alfredo
  with
  spicy garlic shrimp.
• Vegetables Serve your pasta with
  lemon roasted broccoli with Parmesan
  or
  sautéed asparagus.
• Salad Pair it with a
  house salad, or keep it
  simple by tossing bagged salad greens with
  balsamic vinaigrette.

Storage & Reheating

• Refrigerator: Store the sauce in an airtight container in the fridge
  for up to 3 days. It reheats well without separating, unlike traditional
  Alfredo.
• Freezer: Freeze the sauce for up to 2 months. Place it in a freezer
  bag, pressing out excess air, and freeze flat. Thaw in the fridge before
  reheating, or quickly thaw the bag in hot water.
• Reheating: Reheat on the stovetop over low heat or in the microwave.
  Add more milk or broth if the sauce is too thick after reheating, and adjust
  seasonings as needed.
