Ingredients
- 1 medium head cauliflower, cut into florets
- 2 tablespoons butter
- 2 cloves garlic, minced
- 1 cup milk
- 1 cup grated Parmesan cheese
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
How to Make Cauliflower Alfredo Sauce
Step 1: Cook the Cauliflower
Place the cauliflower florets in a steamer basket and steam until very tender, about 8 to 10 minutes.
You can also boil the cauliflower until fork-tender, then drain it thoroughly.
The cauliflower should be soft enough to blend easily.
Step 2: Sauté the Garlic
Melt the butter in a small saucepan over medium-low heat.
Add the minced garlic and cook for about 30 seconds to 1 minute, just until fragrant.
Be careful not to brown or burn the garlic.
Step 3: Blend the Sauce
Place the cooked cauliflower in a blender.
Add the garlic butter, milk, Parmesan cheese, salt, and black pepper.
Blend until completely smooth and creamy.
If the sauce is too thick, add a little more milk until it reaches your desired consistency.
Step 4: Warm the Sauce
Pour the blended sauce into a saucepan and warm gently over low heat for a few minutes.
Do not allow the sauce to boil, as excessive heat can cause the cheese to separate.
Step 5: Serve
Toss the warm sauce with cooked pasta or spoon it over your favorite vegetables, chicken, or potatoes.
Serve immediately while the sauce is warm and creamy.
Tips for the Best Cauliflower Alfredo Sauce
Cook the cauliflower until very tender. Undercooked cauliflower can make the sauce less smooth.
Blend the ingredients thoroughly for the creamiest texture.
Freshly grated Parmesan generally melts more smoothly than pre-shredded cheese.
If the sauce becomes too thick, thin it with a little warm milk or reserved pasta water.
Keep the heat low after adding the Parmesan to help maintain a smooth sauce.

Reheat gently on the stovetop or in the microwave, stirring frequently.
