Ingredients

To make this easy creamy cauliflower Alfredo sauce, you will need the following:

1 medium head of cauliflower (about 4 cups florets, chopped)
2 tablespoons olive oil or unsalted butter
1 medium onion, finely diced
3 garlic cloves, minced
2 cups low-sodium vegetable broth (or chicken broth for more flavor)
1 cup whole milk (or unsweetened almond milk for a dairy-free version)
½ cup freshly grated Parmesan cheese (or nutritional yeast for a vegan option)
½ teaspoon salt (adjust to taste)
¼ teaspoon freshly ground black pepper
1 pinch of nutmeg (optional, enhances creaminess)
12 ounces pasta of choice (fettuccine, linguine, penne, or gluten-free pasta)
Fresh parsley, chopped, for garnish

Instructions

Step 1: Prepare the Cauliflower

Wash and chop the cauliflower into small florets. The smaller you cut them, the faster they will cook. Set aside.

Step 2: Cook the Aromatics

In a large pot, heat 2 tablespoons of olive oil or butter over medium heat. Add the diced onion and sauté for 4–5 minutes until it becomes translucent. Stir in the minced garlic and cook for 1 minute until fragrant.

Step 3: Simmer the Cauliflower

Add the cauliflower florets to the pot along with the vegetable broth. Bring the mixture to a boil, then reduce heat and simmer for 10–12 minutes until the cauliflower is fork-tender.

Step 4: Blend into a Smooth Sauce

Carefully transfer the cauliflower mixture into a blender. Add the milk, Parmesan cheese, salt, pepper, and nutmeg. Blend on high speed until the sauce becomes smooth and creamy. Taste and adjust seasoning if needed.

(Tip: If you prefer less cleanup, use an immersion blender directly in the pot.)

Step 5: Cook the Pasta

While the sauce simmers, bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Drain and reserve about ½ cup of pasta water.

Step 6: Combine Pasta and Sauce

Return the drained pasta to the pot. Pour the cauliflower Alfredo sauce over it. Toss to coat evenly, adding a splash of reserved pasta water if the sauce feels too thick.

Step 7: Garnish and Serve

Sprinkle with freshly chopped parsley and more Parmesan if desired. Serve hot and enjoy.

Conservation and Storage

One of the best things about this cauliflower sauce is how well it keeps.

Refrigeration: Store leftover sauce in an airtight container for up to 4 days. Reheat on the stove with a splash of milk or broth to restore creaminess.
Freezing: Pour cooled sauce into freezer-safe containers. It will last up to 2 months. Thaw overnight in the refrigerator before reheating.
Meal Prep Tip: Make a double batch and freeze half for quick dinners later in the week.

Variations

This recipe is flexible and can be adapted to suit different dietary needs and tastes.

Vegan/Dairy-Free: Use almond milk or oat milk instead of dairy milk. Replace Parmesan with nutritional yeast for cheesy flavor.
Extra Creamy: Add ¼ cup cream cheese or heavy cream while blending for a richer sauce.
Spicy Kick: Stir in ½ teaspoon red pepper flakes for a gentle heat.
Protein Boost: Add grilled chicken, shrimp, or sautéed mushrooms to the pasta before serving.
Herb Twist: Mix in fresh basil, thyme, or rosemary for added flavor depth.

Serving Suggestions
