This Vegan Alfredo Recipe is a little rebellion against the usual dairy-heavy comfort foods. I love how it captures that silky, indulgent feel without any animal products—just honest, plant-based ingredients doing their thing. It’s a dinner that feels fancy but is honestly pretty simple to pull together after a long day.
The secret here is in the creamy cashew base, which mimics that lush, velvety texture we crave in Alfredo. I’ve made it a dozen times, tweaking tiny things—like adding a splash of lemon or a pinch of nutmeg—to keep it interesting, even when I’m craving comfort without the guilt. It’s a dish that feels indulgent but leaves you feeling good afterward.
Focusing on the nostalgic comfort of creamy textures without dairy, this recipe aims to evoke the rich, velvety feel of traditional Alfredo using only plant-based ingredients, making it a cozy yet ethical choice for dairy-free comfort food.
The story behind this recipe
- This recipe was born out of a late-night craving for creamy pasta but with no dairy in sight. I remembered how my grandmother used to make a simple cashew sauce that was surprisingly rich and velvety, yet light. One evening, I threw in a dash of lemon and some nutritional yeast, and suddenly, it felt just right—like a cozy, plant-based hug.
- Cooking this dish reminds me of lazy Sundays spent around the table, laughing, and passing bowls of something unexpectedly indulgent. It’s not just about the ingredients, but the memories stirred up with each stir of the sauce, each bite brimming with nostalgia and a little bit of discovery.

Key ingredients and tips
- Cashews: I love blitzing these until silky smooth, which gives the sauce its creamy richness. If they’re a bit old, soak them longer—about 30 minutes—to soften and blend better.
- Nutritional Yeast: Adds that cheesy, umami punch I crave in Alfredo. If you don’t have it, try a touch of miso paste; it’s not quite the same but still adds depth.
- Garlic: I crush and sauté until fragrant, the aroma filling my kitchen. For a milder flavor, roast the garlic beforehand—sweet and mellow, almost caramelized.
- Lemon Juice: Brightens everything up with a zing. I recommend fresh lemon for that vibrant, citrusy pop—don’t skip it, even if it seems small.
- Plant-Based Milk: I prefer unsweetened almond or cashew milk for a neutral base. For a richer sauce, a splash of coconut milk can add a subtle sweetness and silky texture.
- Nutritional Yeast: (Repeated intentionally for emphasis) It’s the secret to that nutty, cheesy flavor. Keep it in your pantry—once you get used to it, it’s hard to cook without.
- Olive Oil: I use a drizzle for sautéing garlic and to finish the sauce. Look for a fruity, peppery oil—it adds a layer of complexity to the dish.

Step-by-step guide to vegan Alfredo
- Equipment & Tools: Gather a blender (for smooth sauce), a medium saucepan (to cook pasta), a sauté pan (for garlic), and a whisk (to blend).
- Cook pasta: Bring a large pot of salted water (about 4L/1 gal) to a boil at 100°C/212°F. Add your pasta and cook until al dente, about 8-10 minutes. Drain, save a cup of pasta water, and set aside.
- Prepare cashew cream: While pasta cooks, soak 1 cup of cashews in hot water for 15 minutes if they’re old or dry. Drain and rinse.
- Make sauce base: In the sauté pan, heat 1 tbsp olive oil over medium heat (about 160°C/320°F). Add 3-4 minced garlic cloves and sauté until fragrant, about 30 seconds to 1 minute. Watch for a golden hue and a nutty aroma.
- Blend cashews: In the blender, combine soaked cashews, 1 cup plant-based milk, 2 tbsp nutritional yeast, 1 tbsp lemon juice, a pinch of nutmeg, and a pinch of salt. Blend until completely smooth and creamy. If too thick, add a splash more milk or pasta water.
- Combine sauce & pasta: Pour the cashew mixture into the sauté pan with garlic. Warm gently over low heat (about 70°C/160°F), stirring constantly. Add reserved pasta water a little at a time to loosen the sauce to your desired consistency. The sauce should be velvety and cling to the pasta, not runny.
- Finish & serve: Toss cooked pasta into the sauce, ensuring each strand is coated. Taste and adjust salt or lemon if needed. For extra brightness, squeeze a touch more lemon juice. Plate immediately, garnished with fresh herbs if desired.
- Rest & presentation: Let the pasta sit for 1-2 minutes off heat to thicken slightly. Serve hot, with a drizzle of olive oil or a sprinkle of nutritional yeast for extra flavor.
Toss the pasta with the sauce in the pan, then serve immediately. Rest for 1-2 minutes off heat to let the sauce thicken slightly before plating. Garnish with herbs or a drizzle of olive oil if desired.

Equipment
Method
- Bring a large pot of salted water to a rolling boil and cook the pasta until just al dente, about 8-10 minutes. Drain and set aside, saving a cup of pasta water.
- While the pasta cooks, drain your soaked cashews and add them to a blender along with plant-based milk, nutritional yeast, lemon juice, minced garlic, nutmeg, and a pinch of salt. Blend until completely smooth and creamy, scraping down the sides as needed.
- Heat olive oil in a sauté pan over medium heat until shimmering. Add the minced garlic and sauté for about 30 seconds, or until fragrant and just starting to turn golden.
- Pour the cashew cream into the sauté pan with garlic. Warm gently over low heat, stirring constantly, until heated through and slightly thickened, about 3-4 minutes. If the sauce thickens too much, stir in a splash of reserved pasta water to loosen it to a silky consistency.
- Add the cooked pasta to the sauce, tossing gently to coat every strand evenly. Adjust consistency with more pasta water if needed, until the sauce is velvety and clings beautifully.
- Taste and adjust the seasoning with additional salt or lemon juice if desired. Serve immediately, garnished with fresh herbs or a drizzle of olive oil for extra flavor.

Common mistakes and how to fix them

- Splash a bit more lemon juice to brighten dull flavors after cooking.
- Patch over burnt garlic by adding fresh garlic and sautéing briefly again.
- Shield the sauce with a lid if it starts to crackle, to prevent scorching and keep heat even.
Prep, store, and reheat tips
- Prep the cashew cream and chop garlic a day ahead; store in airtight containers in the fridge for up to 24 hours. The nuts may sometimes firm up, so give the blend a quick whirl before reheating.
- Cook the pasta al dente, drain, and toss with a little olive oil to prevent sticking. Keep in an airtight container in the fridge for up to 2 days—reheat with a splash of plant milk or reserved pasta water until velvety.
- The sauce can be made ahead and stored in the fridge for up to 2 days. Reheat gently on low heat, stirring constantly. Expect it to thicken; loosen with a bit more milk or water to restore creaminess.
- For best flavor, reheat the sauce and pasta together, allowing the flavors to meld for a minute or two. The sauce will smell nutty and lemon-bright, with a smooth, inviting texture.
Top questions about vegan Alfredo
1. Can I skip soaking the cashews?
Use soaked, blended cashews for that creamy, velvety texture. If you skip soaking, the sauce might be grainy.
2. Is nutritional yeast necessary?
Yes, nutritional yeast adds cheesy umami. Miso paste can work as a substitute, but it’s saltier and more pungent.
3. How do I know when the pasta is done?
Cook the pasta until just al dente, around 8-10 minutes. Overcooked pasta gets mushy and less appealing coated in sauce.
4. How do I get a smooth sauce?
Add the plant-based milk gradually while blending to reach that smooth, silky consistency. Too much at once can cause clumping.
5. Can I use bottled lemon juice?
Use fresh lemon juice for brightness. Bottled lemon may lack the vibrant, zingy flavor that lifts the dish.
6. How do I reheat leftovers?
Reheat gently on low heat, stirring often. If the sauce thickens, loosen it with a splash of plant milk or reserved pasta water.
7. Can I use different plant milks?
For a richer sauce, swap almond milk with coconut milk, which adds a subtle sweetness and extra creaminess.
8. Should I roast the garlic first?
Roasted garlic adds a mellow, caramelized sweetness. Raw garlic provides a sharper, more pungent flavor, so choose based on your taste.
9. What if my sauce separates?
If the sauce separates, lower the heat and whisk vigorously. Sometimes adding a little more plant milk helps bring it back together.
10. What’s the best way to blend the sauce?
Use a high-speed blender for the creamiest texture. Stop and scrape down the sides for an ultra-smooth, velvety result.
This vegan Alfredo is more than just a pasta toss—it’s a reminder that comfort food can be ethical and still deeply satisfying. The creamy cashew base brings back memories of rich, velvety sauces without any dairy, making every bite feel indulgent and guilt-free.
