But after years of tweaking (and many, many taste tests), this version hits all the right notes. It’s velvety, rich, and has that classic alfredo comfort factor, but with a sneaky veggie boost that’ll make you feel amazing after eating it. Trust me, even my cheese-loving husband does a double take when I tell him there’s no dairy in this bowl of heaven!

Ingredients for Creamy Cauliflower Alfredo
Here’s everything you’ll need to make magic happen – and yes, every single ingredient matters! I’ve learned through trial and error that precision makes all the difference with this recipe.
- 1 medium head cauliflower, chopped into florets (about 4 cups) – trust me, fresh is best here
- 2 cups vegetable broth – I use low-sodium so I can control the salt
- 3 cloves garlic, minced (or more if you’re garlic-obsessed like me)
- 1/2 cup unsweetened almond milk – the plain kind, no vanilla nonsense!
- 2 tbsp nutritional yeast – this is our cheesy flavor secret weapon
- 1 tbsp olive oil – gives that rich mouthfeel
- 1/2 tsp salt – plus more to taste
- 1/4 tsp black pepper – freshly ground if you’ve got it
- 1/4 tsp onion powder – adds depth without chunks
- 12 oz fettuccine – or whatever pasta shape makes you happy
Pro tip: Measure everything before you start cooking – it makes the process so much smoother!
Equipment You’ll Need
Don’t worry – you won’t need any fancy gadgets for this! Just grab:
- A good blender (this is non-negotiable for that silky texture)
- Medium pot for steaming the cauliflower
- Colander to drain your pasta
- Wooden spoon for stirring
- Measuring cups/spoons – eyeballing won’t cut it here
That’s it! Now let’s get cooking.
How to Make Creamy Cauliflower Alfredo
Alright, let’s dive into the good stuff! I’ll walk you through each step to make sure your cauliflower alfredo turns out perfectly creamy every single time. Follow these steps closely – they’re the result of many (many) less-than-perfect batches in my kitchen!
Step 1: Cook the Pasta
First things first – get that pasta going! Bring a large pot of salted water to a rolling boil (it should taste like the sea). Add your fettuccine and cook for 1 minute less than the package suggests – we want it al dente with a slight bite. Here’s my secret: before draining, scoop out about 1 cup of pasta water and set it aside. This starchy liquid is liquid gold for adjusting sauce consistency later. Drain the pasta but don’t rinse it – we need that starch to help the sauce cling!
Step 2: Steam the Cauliflower
While the pasta cooks, let’s work on our sneaky veggie base. In a medium pot, combine the chopped cauliflower and vegetable broth. Bring to a simmer over medium heat, then cover and let it steam for 8-10 minutes. You’ll know it’s ready when a fork slides easily into the florets – they should be super tender but not mushy. Don’t drain the broth! We’re using every last drop of that flavorful liquid for our sauce.
Step 3: Blend the Sauce
Now for the magic! Carefully transfer the cauliflower and all the cooking liquid to your blender. Add the garlic, almond milk, nutritional yeast, olive oil, salt, pepper, and onion powder. Put the lid on tight (hot liquids can be dangerous!) and blend on high for 1-2 minutes until completely smooth. Stop halfway to scrape down the sides – we want zero lumps here! If it seems too thick, add a splash more almond milk. Taste and adjust seasonings – I usually add another pinch of salt at this point.
Step 4: Combine and Serve
Return your drained pasta to the pot and pour that gorgeous creamy sauce over it. Use tongs to toss everything together, adding reserved pasta water a tablespoon at a time if needed to loosen the sauce. The heat from the pasta will warm the sauce through perfectly. Serve immediately with a sprinkle of extra nutritional yeast, fresh parsley, or red pepper flakes if you like a little kick. And voila – dairy-free pasta perfection in under 30 minutes!
Tips for Perfect Creamy Cauliflower Alfredo
After making this recipe more times than I can count, here are my foolproof tips for cauliflower alfredo success:
- Roast your garlic first for deeper flavor – just wrap cloves in foil with olive oil and bake at 400°F for 20 minutes
- Reserve that pasta water! The starchy liquid is perfect for thinning the sauce without diluting flavor
- Blend longer than you think – aim for a full 2 minutes to achieve that restaurant-quality silkiness
- Taste and adjust after blending – sometimes it needs an extra pinch of salt or nutritional yeast to really sing
Bonus tip: If your sauce separates when reheating, just give it a quick blend with a splash of almond milk!
Variations for Creamy Cauliflower Alfredo
Oh, the possibilities! One of my favorite things about this recipe is how easily you can make it your own. Last week I tossed in some sautéed mushrooms and spinach – absolute game changer! Here are my go-to riff ideas:
- Protein boost: Add grilled chicken, shrimp, or chickpeas
- Veggie-packed: Stir in roasted broccoli or sun-dried tomatoes
- Nut-free: Use oat milk instead of almond – just as creamy!
- Spicy kick: Blend in a pinch of red pepper flakes or cayenne
Really, there’s no wrong way to do it – that’s the beauty of this versatile sauce!
Serving Suggestions
Okay, let’s talk about turning this amazing sauce into a full meal that’ll have everyone asking for seconds! My absolute favorite way to serve this is with a big, crisp Caesar salad (dairy-free dressing, of course) and some garlicky roasted broccoli. If you’re feeling fancy, add some garlic bread for dipping – just make sure it’s vegan if you’re keeping it plant-based!
For protein lovers, grilled chicken or shrimp pair perfectly, or keep it simple with some white beans tossed right into the pasta. And hey, sometimes I just eat it straight from the bowl with extra black pepper – no judgment here!
Storage and Reheating
Here’s the good news – this creamy cauliflower alfredo keeps beautifully! Store leftovers in an airtight container in the fridge for up to 3 days. When you’re ready to eat, gently reheat it on the stovetop over low heat, stirring frequently. If the sauce thickens, just add a splash of almond milk or reserved pasta water to loosen it up. Trust me, it tastes just as good the next day – if it lasts that long!

Frequently Asked Questions
Can I freeze the cauliflower alfredo sauce?
Absolutely! The sauce freezes beautifully for up to 3 months. I like to portion it into freezer-safe containers (leave some room for expansion). Thaw overnight in the fridge, then reheat gently on the stove with a splash of almond milk to bring back that creamy texture. Pro tip: Freeze the sauce separately from pasta for best results!
Is nutritional yeast really necessary?
I know it sounds fancy, but trust me – it’s the secret to that cheesy flavor without dairy! If you’re in a pinch, you could substitute with a tablespoon of white miso paste or just skip it, but you’ll miss that umami depth. Once you try it, you’ll understand why I always keep nutritional yeast in my pantry!
My sauce turned out too thin – how can I fix it?
No worries! Simply return it to the blender and add a handful of raw cashews or another 1/4 cup of cauliflower. Blend until smooth – the extra starch will thicken it right up. Alternatively, simmer the sauce in a pan for 5-10 minutes to reduce. Remember, it thickens as it cools too!
