Sauces & Condiments
This alfredo pasta sauce without cream delivers restaurant-quality richness using just cashews, garlic, and olive oil—no heavy cream required. The secret lies in blending soaked cashews into a velvety base that mimics traditional Alfredo while keeping it dairy-free and nutty.
I developed this recipe after years of perfecting plant-based sauces that never compromise on flavor or texture.
The magic happens when you toast the garlic and cashews together, creating deep, aromatic layers before blending with warm broth and nutritional yeast for that signature cheesy depth. This sauce is silky, nutty, and rich, clinging perfectly to pasta without weighing it down.
It's foolproof for anyone avoiding dairy or seeking a lighter yet equally satisfying version.
What sets this apart is how quickly it comes together—just 10 minutes of prep and 5 minutes of blending—while delivering a sauce that's far more complex than store-bought alternatives.
The cashew base adds natural creaminess, while garlic and herbs provide the savory backbone that makes Alfredo so beloved. Perfect for fettuccine, chicken, or even as a creamy veggie dip.
Once you try this version, you'll never go back to heavy cream-based sauces. The nutty richness pairs beautifully with roasted vegetables or grilled proteins, making it versatile enough for any meal. Let's make this sauce that tastes like comfort food, but with a lighter touch.
Ingredients for alfredo pasta sauce recipe without cream
Cashews and garlic create restaurant-quality Alfredo richness without dairy or heavy cream.
| Ingredient | Amount | Notes |
|---|---|---|
| Raw Cashews 🥜 | 1 cup | Unsalted, soaked for creaminess |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity variety |
| Garlic Cloves 🧄 | 4 cloves | Fresh, peeled and toasted |
| Vegetable Broth 💧 | 1 ½ cups | Low-sodium, warm before blending |
| Nutritional Yeast 🧀 | ¼ cup | Fortified, for cheesy depth |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, brightens flavor |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| White Pepper 🌶️ | ¼ tsp | Freshly ground for subtle warmth |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for freshness |
| Ground Nutmeg 🌿 | ¼ tsp | Freshly grated preferred |
The cashews are the star here—Trader Joe's or Costco sell the best unsalted varieties for this. Soak them in warm water for 15 minutes before blending to break down their natural oils, which create that velvety texture. Fresh garlic is non-negotiable; roast it lightly in olive oil until golden for deeper flavor. Nutritional yeast from Bragg or bulk bins adds that signature cheesy umami—don't skip it. The olive oil should be extra-virgin, not the cheap stuff; you'll taste the difference in every bite.
No cashews? Silken tofu or blended white beans work in a pinch, though texture will differ slightly. Short on parsley? Fresh basil or chives add brightness too. Want extra richness? Add 1 tbsp tahini to the blend. The vegetable broth can be swapped for white wine or coconut milk if you prefer, but keep it warm to help emulsify the sauce. For a nut-free version, blend soaked sunflower seeds instead—same technique, slightly different flavor profile.
This sauce keeps beautifully—5 days refrigerated or 3 months frozen. For freezing, portion into ice cube trays before transferring to a bag. Reheat gently with a splash of water or pasta water to restore creaminess. I always make double batches; it disappears faster than you'd think. The nutmeg and white pepper lose potency over time, so store them in a cool, dark place. If your sauce separates, just whisk in a splash of warm water or pasta water until smooth again.

Step-by-step instructions for creamy cashew Alfredo sauce
Here's how to craft a velvety, nutty alfredo that rivals traditional versions—no dairy required.
👨🍳 Step 1: Soak and Toast the Cashews
Place the 1 cup raw cashews in a medium bowl and cover completely with hot water. Let them soak for at least 2 hours—this ensures they blend into a silky texture. I like to soak them overnight for maximum creaminess, but 2 hours works in a pinch.
After soaking, drain and transfer the cashews to a dry skillet over medium heat. Toast them for 3-4 minutes, stirring constantly, until they develop a golden aroma and slight color. This step deepens their nutty flavor and removes any raw taste. Let them cool slightly before blending—hot cashews can scorch your sauce.
🍳 Step 2: Blend the Base Ingredients
In a high-speed blender, combine the toasted cashews, 0.5 cup extra-virgin olive oil, 4 cloves garlic, 1.5 cups vegetable broth, 0.25 cup nutritional yeast, and 1 tbsp lemon juice. The nutritional yeast adds that signature cheesy depth without dairy, while the lemon brightens the richness.
Blend on high for 1-2 minutes until completely smooth. You're aiming for a texture like heavy cream—no lumps, no grit. If it's too thick, add 1-2 tablespoons of warm water at a time until it reaches a pourable consistency. The sauce should coat the back of a spoon with a velvety sheen.
🔥 Step 3: Season and Simmer for Depth
Transfer the blended sauce to a saucepan and place over medium-low heat. Add 0.5 tsp salt, 0.25 tsp white pepper, and 0.25 tsp ground nutmeg, stirring constantly to dissolve the spices. Let the sauce simmer gently for 5-7 minutes, stirring occasionally—this allows the flavors to meld and the sauce to thicken slightly.
Here's the thing—cashew sauces can separate if heated too vigorously. Keep the temperature low and stir frequently. You'll know it's ready when it coats the back of a spoon smoothly and has a glossy finish. Taste and adjust seasoning if needed; the nutmeg adds warmth that balances the richness.
🥘 Step 4: Finish with Fresh Herbs
Remove the sauce from heat and stir in the 0.125 cup chopped fresh parsley. This adds a bright, fresh note that cuts through the richness. Let the sauce sit for 5 minutes before serving—this resting period allows the flavors to fully integrate.
The sauce should now be thick enough to cling beautifully to pasta without being gluey. If it's too thick after resting, thin it with a splash of warm pasta water. Serve immediately over your favorite pasta, tossing well to coat each strand. The sauce will continue to thicken slightly as it sits, so don't worry if it looks perfect right away.
Pro Tips For Making Alfredo Pasta Sauce Recipe Without Cream
- SOAK CASHEWS LONG ENOUGH: I learned this the hard way—those 10 minutes on the package aren’t enough. Soak raw cashews in hot water for at least 30 minutes, or better yet, overnight in the fridge. They’ll blend into silkier sauce, not gritty paste, and save you from overworking the motor later.
- TOAST GARLIC LOW AND SLOW: Skip the high-heat sizzle—it burns before it browns. Cook minced garlic in olive oil over lowest possible heat until just golden (about 5-7 minutes). Patience here means no bitter aftertaste, and the aroma will make your whole kitchen smell like a pasta shop.
- SALT THE BROTH EARLY: Taste your vegetable broth before adding it to the sauce. If it’s bland, season it now—you can’t fix flat flavor later. Nutritional yeast and cashews mask saltiness, so err on the side of more now. (Yes, even if you’re serving it to picky eaters.)
- BLEND IN STAGES: Start with half the broth and cashews, blend until smooth, then add the rest. This prevents clumping and lets you adjust thickness on the fly. If it’s too thick, add a splash more broth; too thin? Simmer it down. No guessing, just control.
Pro cooking tips for this dish
Blending Like a Pro
Your blender is the MVP here—use a high-speed blender like a Vitamix or Ninja for that ultra-smooth texture. If your sauce looks grainy, add 1-2 tablespoons of warm water and blend again.
I've found that blending in short bursts (30 seconds on, 30 seconds off) prevents overheating and keeps the sauce silky. 💫
Toast Those Garlic Cloves
Don't skip toasting the garlic—it's where the magic happens! Lightly toast 4 cloves in 0.25 cup olive oil over medium heat until golden brown (about 2-3 minutes).
This step adds depth that raw garlic can't match. Pro tip: Use a garlic press instead of mincing for smoother blending and better flavor extraction.
Emulsify with Warm Broth
Always use warm vegetable broth (not cold) when blending—this helps emulsify the sauce for that creamy consistency. If your sauce separates after heating, whisk in 1 tablespoon of warm pasta water to bring it back together.
I've learned this trick from Italian nonnas who swear by it for traditional Alfredo too!
Low and Slow Simmering
Never rush the simmering phase—keep heat at medium-low and stir constantly. The sauce should gently bubble but not boil vigorously. If it gets too hot, it'll break and separate. Taste as you go; the nutmeg and white pepper need time to bloom and balance the richness. 🌡️
Herb Finishing Secrets
Add fresh parsley off-heat to preserve its vibrant color and bright flavor. For extra depth, I sometimes stir in 1 teaspoon of lemon zest along with the parsley.
This adds a citrusy brightness that cuts through the sauce's richness beautifully. Always let the sauce rest 5 minutes before serving—this lets all the flavors meld perfectly.
Thickness Adjustments
If your sauce is too thick after resting, thin it with warm pasta water (not cold) to maintain creaminess. For extra richness, stir in 1 tablespoon of tahini or 1 teaspoon of Dijon mustard—both add complexity without altering the texture.
The sauce should coat the back of a spoon but still flow smoothly when poured. 🥄

Frequently asked questions
Can I make this sauce without cashews?
Yes! For a nut-free version, blend 1 cup soaked sunflower seeds instead—they create a similar creamy texture. Another option is silken tofu or white beans, though the flavor will differ slightly. Always soak seeds/beans first to ensure smooth blending.
Why does my sauce look grainy after blending?
Graininess usually means the cashews weren't soaked long enough or the blender wasn't powerful enough. Try adding 1-2 tablespoons of warm water and blending again in 30-second bursts. For best results, use a high-speed blender like a Vitamix. If it's still grainy, strain through a fine-mesh sieve.
How do I prevent the sauce from separating when reheating?
Sauce separation happens when heated too quickly. To fix it, whisk in 1 tablespoon of warm pasta water or vegetable broth while stirring constantly over low heat. For prevention, reheat gently on medium-low and stir frequently. The sauce should never boil—just warm through.
Can I use coconut milk instead of cashews?
You can try, but the texture will be thinner and less nutty. For best results, use ½ cup full-fat coconut milk plus ¼ cup extra olive oil to mimic the richness. The flavor will have a slight coconut undertone, so it works best with tropical-inspired dishes like pineapple-chicken pasta.
What's the best pasta to pair with this sauce?
This sauce clings beautifully to fettuccine or tagliatelle, but works with any pasta shape. For extra texture, try pappardelle or linguine**. If using a wider noodle, you may need slightly more sauce to fully coat each strand. Save some pasta water to thin the sauce if needed.
