Creamy Cauliflower Alfredo Sauce

This gluten-free and nut-free Cauliflower Alfredo offers a lighter twist on the classic rich and creamy sauce without sacrificing any flavor. It’s perfect for those who want comfort food that feels indulgent but is actually nutritious and easy to make.

I first made this sauce when trying to enjoy Alfredo without the heaviness. It quickly became a favorite for its creamy texture and gentle garlic kick that my whole family loves.

Gather Your Ingredients

• 1 head cauliflower cut into florets: This is the base of the sauce and gives that creamy texture when blended
• 2 tablespoons olive oil: Adds richness and helps sauté the shallot and garlic without burning
• 1 shallot minced: Provides a sweet, onion-like depth that rounds out the flavor
• 6 garlic cloves minced: Garlic is essential here for that classic Alfredo flavor with a bit of a punch
• ¼ teaspoon crushed red pepper: Adds subtle heat to balance the creaminess adjust to your spice preference
• 1 teaspoon salt: Enhances all the flavors and brings out the natural sweetness of the cauliflower
• ½ teaspoon white pepper: Offers a mild peppery spice without visible black flecks
• ½ cup milk: Creamy element to smooth out the sauce can substitute plant-based milk if preferred
• 1 pound cooked fettuccine: Use gluten-free pasta to keep it gluten free or your favorite noodles

How to Make It

Sauté the Aromatics:

Heat olive oil in a large skillet over medium heat. Add the minced shallot and garlic along with the crushed red pepper. Cook gently for about 1 to 2 minutes until the garlic becomes soft and releases its aroma but does not brown. This step builds a flavorful base for the sauce.

Cook the Cauliflower:

Bring a large pot of water to a boil. Add cauliflower florets and cover. Let them cook for 8 to 10 minutes or until they become very tender when pierced with a fork. Reserve 1 cup of the cooking water before draining the cauliflower. This starchy liquid helps loosen the sauce later.

Combine and Blend:

Transfer the cooked cauliflower to your blender along with the sautéed shallot and garlic, reserved cooking liquid, milk, salt, and white pepper. Cover the vent of your blender lid with a thin kitchen towel for steam to escape safely and blend until the sauce is completely smooth and creamy. This takes about a minute. If the sauce looks too thick, add a few drops of water, milk, or olive oil and blend again.

Toss and Serve:

Mix the sauce thoroughly with cooked fettuccine right away so the pasta absorbs all the flavor. Serve immediately for the best creamy texture.

I love how cauliflower transforms into such a luscious sauce that no one guesses it is vegetable-based. A memorable moment was when I served this to a friend who usually avoids veggies, and she asked for seconds without knowing the secret.

Flavor Boosters

Storage Tips Keep leftover sauce chilled in a tightly sealed container and reheat gently on the stove adding a splash of milk or water to bring back creaminess. Pasta with sauce stores well separately to avoid sogginess. Ingredient Substitutions Swap milk for unsweetened almond, oat, or cashew milk to make it vegan and nut-free. More olive oil or a little plant butter can increase richness. Trying a pinch of nutritional yeast adds a subtle cheesy flavor without dairy.

Serving Suggestions

Serve this Alfredo with a side of steamed or roasted green veggies for a balanced plate. Fresh herbs like parsley or basil sprinkled on top brighten the dish. Add grilled chicken or shrimp for extra protein.
