Cauliflower Alfredo Sauce

After years of making my Cauliflower Mac and Cheese and requests for an easy Alfredo sauce, this recipe seemed like a must-make. The sauce is incredibly easy, it’s just as creamy as you’d want from an Alfredo, and it’s not remotely intimidating. Plus, you can even make the sauce ahead of time and stash it in the fridge, so when you’re getting ready for dinner all you need to do is cook the pasta. I also love this as a seriously easy way to include veggies, protein, and calcium in one simple meal for the whole family. I love using Stonyfield plain Greek yogurt here since it’s mild in flavor and has the perfect creamy consistency. Plus, Stonyfield yogurt is made with high-quality organic ingredients, without the use of toxic, persistent pesticides. We started using it when our kids were babies and it’s still a regular on our grocery list. (You may also like my Pasta with Yogurt Sauce and my Lemon Ricotta Pasta.)

Ingredients You Need

Here’s a look at the ingredients you need to have on hand to make this pasta recipe. Sign up for our email updates to get tips and ideas sent to your inbox.

Cauliflower florets: You can use fresh or frozen cauliflower, from a head of cauliflower or precut from the store. Plain Greek yogurt: Preferably whole-milk fat, this type of yogurt will yield the creamiest results. You can use regular yogurt if that’s what you have, but you’ll want to decrease the amount to ⅓ to ensure the mixture is still very creamy. Milk: I use whole milk in this recipe since that’s what we typically have in our house. I like to warm it just slightly to help the sauce not be cold when it’s mixed with the pasta. Shredded cheddar cheese: This gets blended into the sauce to add cheesy flavor and creaminess. You can use preshredded cheese from the store or grate it on a box grater. Unsalted butter: Adding butter to the sauce adds richness and flavor. Grated Parmesan cheese: This is key in an Alfredo pasta, and I prefer to use grated Parmesan since the flavor is typically stronger and more delicious. Garlic powder: Optionally, you can add garlic powder to the sauce for a hit of extra flavor if you’d like. Pasta: This type of cream sauce is typically tossed together with al dente, fork tender pasta noodles, such as linguine or fettuccine.

Step-by-Step Instructions

Below is an overview of how to make the recipe so you know what to expect. Scroll down to the end of the post for the full amounts and timing.

How to Store

Store any leftover sauce in an airtight container in the fridge for 3-5 days. Warm for 30-seconds in the microwave to serve, or simply stir into very warm pasta. Reheat leftover pasta on a heat-safe plate for 30 to 60-seconds in the microwave or until warmed through.

Best Tips for Success

Omit the garlic powder if you’re worried that the kids may not like it. Taste the sauce and adjust the salt as needed. Stir the sauce into the pasta right before serving. Use full-fat Greek yogurt made with whole milk for maximum creaminess. Sprinkle with additional Parmesan, cracked black pepper, or minced fresh parsley if desired. Add white beans, peas, diced chicken, diced shrimp, or another protein if desired. Use gluten-free pasta as desired. Use plain nondairy milk such as almond milk if needed.
