Key Ingredients
A great alfredo sauce is all about luxurious texture and bold, cheesy flavor—and we’re getting there without a drop of dairy. The key? A handful of simple ingredients, each pulling its weight to create that rich, silky, restaurant-level sauce that clings to pasta like a charm. Here’s what you’ll need:
- Cashews: The Secret to a Creamy Sauce – Cashews do something kind of magical when blended—they turn into a buttery, thick, ultra-smooth cream that rivals any dairy-based alfredo. Soak them first, and they’ll blend effortlessly into a silky sauce without a hint of graininess.
- Vegan Butter: The Indulgent Factor – A little bit of vegan butter ups the richness and gives this sauce that classic restaurant-style decadence. We used Miyoko’s because it’s cultured and flavorful, but Earth Balance and Violife Plant Butter work beautifully too.
- White Onion: Sweet, Savory, Essential – Instead of heavy cream, we’re coaxing out natural sweetness and depth by sautéing onions in plant-based butter until they’re soft and golden. This adds richness without making the sauce taste oniony—just a subtle, savory balance.
- Vegan Parmesan: The Big Cheese Energy – This is where that signature cheesy bite comes in. Vegan parmesan melts straight into the sauce, adding bold umami depth and a little saltiness. Best brands? Try Forager, Violife, Follow Your Heart, or Trader Joe’s.
- Garlic Powder: Subtle but Essential – Fresh garlic is great, but in a smooth, creamy sauce, garlic powder blends in seamlessly without overpowering everything. It’s an easy way to add warm, nutty depth.
- Lemon Juice: The Brightness Factor – A squeeze of lemon at the end lifts the richness and keeps the flavors balanced. It doesn’t make the sauce taste lemony—it just keeps things from feeling too heavy. Think of it as the flavor whisperer in the background, making sure everything stays vibrant.
- Chives: Optional but Highly Recommended – A sprinkle of chopped chives on top? Not required, but definitely encouraged. They add a hint of freshness, a little color, and a mild oniony pop that makes the whole dish feel fancy with minimal effort.
How to Make the Creamiest Vegan Alfredo
A good alfredo sauce should be lusciously creamy, deeply savory, and cling to pasta like a dream. This one checks all the boxes—and comes together in just 20 minutes. It’s mostly hands-off, but the result tastes like you put in serious effort. For full recipe instructions, scroll to the end of this post!
- Step 1: Blend Up That Cashew Cream – Soak the cashews overnight (or do a quick hot water soak if you’re short on time), then blend with a little water until ultra-smooth. This is what gives the sauce its buttery, silky texture—no dairy required.
- Step 2: Sauté the Onions in Vegan Butter – Melt vegan butter in a pan, then let those onions cook low and slow until soft and golden. This adds a subtle sweetness and deepens the richness without overpowering the sauce.
- Step 3: Stir in Vegan Parmesan & Garlic Powder – Once the onions are soft, stir in vegan parmesan shreds and garlic powder. The cheese starts to melt, infusing the butter with a bold, savory bite that makes this sauce next-level.
- Step 4: Blend Everything Together – Transfer the onion mixture to a blender, add the cashew cream, and blend until completely smooth and velvety. This is where the magic happens—it goes from a handful of ingredients to a restaurant-worthy sauce.
- Step 5: Finish with Lemon Juice & Chives – A squeeze of lemon balances the richness (without making it taste lemony!), and the chives add a touch of freshness. At this point, you can thin it out with pasta water until you hit that perfect, glossy, pourable consistency.
Pro Tips for the Creamiest Cashew Alfredo Sauce
A good alfredo sauce should feel luxuriously rich, effortlessly smooth, and just the right amount of garlicky. The best part? You don’t need dairy (or advanced kitchen skills) to make it happen. Here’s how to take your vegan alfredo from great to completely unforgettable.
- Soak (or Boil) Your Cashews: For the silkiest sauce, give those cashews a little spa treatment. An overnight soak makes blending effortless, but if you’re short on time, pour boiling water over them and soak for 10 minutes. Either way, you want them super soft to ensure a totally smooth finish.
- Cook the Onions Until Sweet & Soft: Don’t rush this step—a little patience here brings major flavor payoff. Cooking the onions low and slow unlocks their natural sweetness, which balances the richness of the cashew cream and cheese.
- Use a High-Speed Blender: A good blender makes all the difference. If yours isn’t high-powered, blend for an extra minute or two and scrape down the sides as needed. The goal? No tiny cashew bits—just pure, velvety smoothness.
- Don’t Skip the Lemon Juice: It’s not here to make your sauce taste citrusy—it’s here to cut through the richness and keep every bite balanced. Just a small squeeze at the end keeps things bright and creamy (not heavy and cloying).
- Adjust Consistency with Pasta Water: A splash of reserved pasta water loosens up the sauce and helps it cling to every noodle like it was made for it (because it was). Start with a couple of tablespoons and stir until you hit that perfect, glossy texture.

- Yield: 3 cups
- Diet: Vegan
Description
If a sauce could be a main character, this vegan alfredo sauce would be it. Creamy cashew richness, melty vegan parmesan, and just the right hit of garlic come together in 20 minutes—fast enough for a weeknight but fancy enough for date night. It’s the kind of sauce that makes any bowl of pasta feel like an event.
Ingredients
For The Vegan Alfredo Sauce
- 1 cup raw cashews, soaked in plenty of water overnight
- 1/4 cup vegan butter (I used Miyoko’s cultured vegan butter)
- 1 cup diced white onion
- 7 oz. vegan parmesan cheese shreds (I used Forager parmesan shreds)
- 1/2 teaspoon garlic powder
- 1 squeeze of lemon
- 1 TB finely chopped chives (optional)
To Serve
- 2 servings of pasta (I used tagliatelle)
- 2 recipes of shiitake bacon
- the zest from half a lemon
- a couple small squeezes of lemon
- 1 TB chopped chives, to garnish
- 1/4 cup flat parsley, to garnish
Instructions
To Make the Vegan Alfredo Sauce
- Blend the Cashews: Drain and rinse the soaked cashews, then add them to a high-speed blender. Pour in just enough water to slightly cover them. Start blending on low, gradually increasing to high speed, and blend for about 30 seconds or until completely smooth.
- Sauté the Onions: Melt the vegan butter in a small Dutch oven or heavy-bottomed pot over medium heat. Add the diced onions and cook for about 5 minutes, stirring occasionally, until soft and fragrant.
- Melt the Vegan Parmesan: Stir in the vegan parmesan shreds, reduce the heat to medium-low, and cover. Let them melt for 2–3 minutes—they don’t need to be fully melted, just softened.
- Blend Until Velvety: Transfer the onion-parmesan mixture to the blender. Add the garlic powder and blend until completely smooth and creamy.
- Finish with Lemon & Chives: Add a squeeze of fresh lemon juice and chives (if using), then blend briefly to combine.
To Assemble the Dish
- Cook the Pasta: Prepare the pasta of your choice according to package instructions. Before draining, reserve 1 cup of the pasta water—this will help thin the sauce later if needed.
- Toss with Alfredo Sauce: In a large bowl, combine the pasta with the desired amount of vegan Alfredo sauce. Add a few splashes of the reserved pasta water, stirring until the sauce reaches your preferred consistency.
- Add Finishing Touches: Fold in the shiitake bacon and lemon zest for extra flavor.
- Serve & Garnish: Divide into bowls, top with chopped chives and parsley, and finish with an extra squeeze of lemon if desired. Serve immediately and enjoy!
Notes
Storage & Reheating
- Refrigerate: Store leftover vegan Alfredo sauce in an airtight container in the fridge for up to 5 days. The sauce will thicken as it chills.
- Reheat: Warm it gently in a saucepan over low heat, stirring frequently. If it’s too thick, add a splash of pasta water, plant milk, or vegetable broth to bring back that silky consistency. Avoid high heat—it can cause the sauce to separate.
Freezing
- This sauce freezes well! Let it cool completely, then transfer it to a freezer-safe container. Freeze for up to 3 months.
- To reheat, thaw in the fridge overnight, then warm on the stovetop over low heat, whisking in a little liquid as needed.
Meal Prep Tips
- Make Ahead: Blend the sauce up to 3 days in advance and store it in the fridge. Warm and thin it out with a splash of liquid before serving.
- Double It! This sauce is easy to scale up for meal prep. Freeze portions in single-serving containers for quick weeknight dinners.
Troubleshooting
- Too Thick? Add a little pasta water, plant milk, or broth and stir until smooth.
- Too Thin? Simmer over low heat for a few minutes to reduce, or blend in a few soaked cashews for extra body.
- Not Cheesy Enough? Add an extra sprinkle of vegan parmesan or a touch of nutritional yeast for more umami depth.
- Want More Garlic? Stir in a little roasted garlic or sautéed fresh garlic for extra flavor.
