Ingredients for alfredo pasta sauce recipe without cream
Nine simple ingredients transform into creamy, restaurant-style Alfredo without dairy.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for toasting |
| Garlic Cloves 🧄 | 6 whole | Peeled, for toasting |
| Raw Cashews 🥜 | 1 cup | Unsalted, soaked overnight |
| Nutritional Yeast 🍞 | ½ cup | Fortified, for cheesy flavor |
| Vegetable Broth 💧 | 1 cup | Low-sodium preferred |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| White Wine Vinegar 🍷 | 1 tsp | For tangy balance |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Plain Water 💧 | ½ cup | For thinning as needed |
The butter and garlic are your flavor foundation. Use unsalted butter—it gives you full control over seasoning. Toast the garlic in cold butter until golden (about 5 minutes), not browned—this adds nutty depth without bitterness. Trader Joe's sells pre-peeled garlic cloves, which saves time. For the cashews, soak them overnight in water—this makes them blend silky smooth. I usually double the batch and store the extra in the freezer for quick sauce days. Nutritional yeast is the secret weapon here—Bob's Red Mill brand is my go-to for that authentic cheesy flavor.
No cashews? Walnuts or almonds work in a pinch, but soak them longer (up to 12 hours). Short on nutritional yeast? Miso paste at half the amount adds umami, though it'll be less cheesy. The white wine vinegar might seem odd, but it brightens the sauce—substitute lemon juice if you don't have it. For a richer texture, blend in 1/4 cup silken tofu with the cashews. And if your sauce gets too thick, just add a splash of warm water or broth—it should coat the back of a spoon but still flow smoothly.
This sauce keeps beautifully. Store it in an airtight jar in the fridge for up to 5 days—it actually tastes better after the first night as flavors meld. For freezing, portion into ice cube trays, then transfer to a bag. Thaws in minutes under warm water. The sauce reheats perfectly—just stir in a little water or broth if it thickens too much. I always make extra because it disappears fast, especially when tossed with fettuccine or gluten-free noodles. Leftovers make great pasta salad too!
Why You'll Love This Recipe
- No-Fuss Blend: I swear by this sauce because it’s literally three ingredients blended until smooth—no straining, no waiting for cashews to soak. Toss in the broth, simmer, and you’ve got a velvety base in 10 minutes flat, even if you’re still holding a toddler on one hip.
- Umami Magic: That nutritional yeast? It’s the secret weapon—cheesy, nutty, and rich without a drop of dairy. The cashews add natural creaminess while the garlic roasts gently in the butter, giving it that deep, savory punch that makes you forget it’s “healthy.”
- Weeknight & Meal Prep: Between us, this sauce is my go-to for busy nights—toss it with any pasta, or use it as a base for veggie stir-fries. It even reheats beautifully, so I make a big batch on Sundays and freeze half for when I’m too tired to cook.
- Budget-Friendly Luxury: Cashews and nutritional yeast might sound fancy, but they stretch further than heavy cream. A small bag of cashews makes four batches of sauce, and the broth keeps it light on calories but heavy on flavor—no guilt, just satisfaction. (Yes, even on a Tuesday night.)
Step-by-step instructions for creamless Alfredo pasta sauce
Here's how to make a velvety, nutty Alfredo sauce without cream—it's easier than you think.
Toast the Garlic and Butter for Deep Flavor
Start by melting the 0.5 cup unsalted butter in a medium saucepan over medium-low heat. Once melted, add the 6 peeled garlic cloves and let them cook gently for 3-4 minutes until they turn golden brown and smell intensely fragrant. This step is crucial—it builds the nutty, toasty base that replaces cream.
Watch the garlic closely—it burns quickly once it turns golden. If it starts to darken too much, remove the pan from heat for 30 seconds to cool slightly before continuing. The butter should foam and bubble gently, creating a rich foundation for the sauce.
Blend the Cashews and Nutritional Yeast
While the garlic toasts, drain and rinse the 1 cup soaked raw cashews if they haven't been soaked overnight. Transfer them to a blender along with the 0.5 cup nutritional yeast, 1 cup vegetable broth, 1 tbsp lemon juice, 1 tsp white wine vinegar, 1 tsp salt, and 0.5 tsp black pepper. Blend until completely smooth, scraping down the sides as needed.
The cashews act as a natural thickener and fat substitute, while the nutritional yeast adds that signature cheesy depth. Blend for about 1-2 minutes until no lumps remain. If the mixture is too thick, add 1-2 tablespoons of plain water to help it blend smoothly.
Combine and Simmer the Sauce
Pour the blended cashew mixture into the saucepan with the toasted garlic and butter. Stir well to combine, then bring the mixture to a gentle simmer over medium heat. Let it cook for 5-7 minutes, stirring occasionally, until it thickens slightly and coats the back of a spoon.
If the sauce is too thick, whisk in 1-2 tablespoons of plain water at a time until it reaches a smooth, pourable consistency. The sauce should be creamy but still coat the pasta nicely without being gluey. Taste and adjust seasoning—add more salt or lemon juice if needed.
Finish with Fresh Lemon and Pepper
Once the sauce is smooth and well-combined, remove it from heat. Stir in an extra ½ teaspoon of black pepper and ½ tablespoon of lemon juice to brighten the flavors. The sauce should be rich, nutty, and slightly tangy—perfect for tossing with cooked pasta.
For best results, keep the sauce warm in the saucepan until ready to use. If it thickens too much while waiting, thin it with a splash of hot vegetable broth or plain water. This sauce holds up well when reheated, making it ideal for leftovers.
Pro Tips For Making Alfredo Pasta Sauce Recipe Without Cream
- TOAST THE CASHEWS: Soak your raw cashews for at least 2 hours—or overnight if you’re impatient like me—then drain and pat them thoroughly dry before blending. I learned this the hard way: wet cashews turn your sauce into a gluey mess. A quick 30-second toast in a dry pan before blending adds depth without burning.
- LOW AND SLOW WITH BUTTER: Melt the unsalted butter over medium-low heat—no rushing. If you crank it too high, the garlic will burn before the butter even foams, and you’ll taste smoke instead of nutty richness. Let it bubble gently, and resist the urge to stir constantly; just swirl the pan occasionally.
- BLEND IN STAGES: Start with just the soaked cashews, garlic, and a splash of broth in the blender—no yeast yet. Pulse until smooth, then add the nutritional yeast in small batches while tasting. Too much at once? Your sauce will taste bitter. I usually add half the yeast first, then adjust.
- SALT THE BROTH FIRST: Season your vegetable broth before adding it to the sauce—about ½ teaspoon salt per cup. Nutritional yeast is salty, and if you wait to season, your sauce might end up flat. Trust me, your taste buds will notice the difference, especially if you’re using low-sodium broth.
Common mistakes when making great alfredo pasta sauce recipe without cream
Skipping the Soak
One of the biggest mistakes is skipping the overnight soak for the cashews. Raw cashews are tough and won’t blend smoothly without it. I’ve tried blending them dry, and the result is a gritty, uneven sauce. Soak them in water for at least 8 hours—or overnight for best results.
If you’re short on time, boil them for 10 minutes first, then blend. Never skip this step, or your sauce will taste unpleasantly grainy. 🥜
Overcooking the Garlic
Burnt garlic ruins the entire sauce. The moment it turns golden brown, it’s ready—don’t let it darken further. I’ve seen people walk away for just a minute, and suddenly, the kitchen smells like smoke. If your garlic starts to brown too quickly, reduce the heat to low and stir constantly.
The goal is nutty, not bitter. A quick sniff test tells you when it’s perfect—intense but not harsh. 🧄
Using Unsalted Broth
Low-sodium broth is key here, but some people forget to check the label. If you use regular broth, your sauce will be overwhelmingly salty. I always double-check the label before adding 1 cup vegetable broth.
If you’re stuck with regular broth, cut the salt in the recipe by half. Taste as you go—adjusting seasoning is easier than fixing oversalted sauce later. 🧂
Not Blending Long Enough
Rushing the blending process leads to lumps, and lumps mean a textured, unsatisfying sauce. Blend the cashew mixture for at least 1-2 minutes, scraping down the sides every 30 seconds.
If your blender isn’t powerful enough, add 1-2 tablespoons of water to help it puree smoothly. A smooth sauce is the difference between homemade and store-bought quality. ⚡
Ignoring the Simmer
Simmering the sauce is where the magic happens—it thickens and melds flavors. Skipping this step or walking away while it cooks can leave you with a thin, watery mess. Keep the heat at medium-low and stir occasionally for 5-7 minutes.
If it thickens too much, thin it with a splash of warm water or broth. Patience here ensures a creamy, restaurant-worthy finish. 🔥
Overlooking the Lemon
The lemon juice isn’t just for flavor—it brightens the sauce and balances the richness. Some people skip it or use too little, leaving the sauce flat. Add the full 1 tablespoon of lemon juice (plus the extra ½ teaspoon at the end**)—it’s what makes this sauce taste fresh and vibrant.
If you’re not a fan of lemon, a splash of white wine vinegar works too. 🍋

Frequently asked questions
Can I make this sauce without cashews?
Yes! For a nut-free version, substitute 1 cup cooked silken tofu or ½ cup white beans (rinsed well) for the cashews. Blend with the same liquid ingredients, but you may need to add 1-2 extra tablespoons of water for smoothness. The texture will be slightly different but still creamy and delicious.
Will this sauce work with gluten-free pasta?
This creamy sauce pairs beautifully with gluten-free noodles like brown rice or chickpea pasta. The rich, nutty flavor actually enhances the texture of gluten-free strands. Just toss the sauce with freshly cooked pasta and adjust consistency with a splash of warm water if needed.
How can I make this sauce even creamier?
For extra richness, add 1 tablespoon of olive oil to the toasted garlic butter or blend in ¼ cup coconut cream with the cashews. Another trick is to simmer the sauce for 10 extra minutes on low heat—this deepens the flavor and thickens the texture naturally.
Can I use this sauce for other dishes besides pasta?
This versatile sauce works perfectly for creamy dips, veggie dinners, or even as a base for stuffed peppers. For dips, thin it slightly with more broth. For vegetables, toss with roasted broccoli or asparagus. The nutty flavor also complements grilled chicken or tofu. The possibilities are endless!
Why does my sauce taste bitter?
Bitterness usually comes from overcooked garlic or nutritional yeast that's too strong. Keep the garlic golden brown (not dark), and use Bob's Red Mill nutritional yeast for the best flavor. If needed, balance bitterness with an extra ½ teaspoon of lemon juice or a pinch of salt. Taste as you go!
