Creamy Cashew Alfredo
Silky ribbons of pasta cloaked in a rich, garlicky sauce blended from soaked cashews, coconut milk, and nutritional yeast, brightened with lemon juice and finished in warm olive oil.
Why You'll Love This Recipe
This is a weeknight pasta for anyone who loves the plush, garlicky comfort of a classic cream sauce but wants to skip the butter and cream. The whole dish comes together in about the time it takes the pasta to boil, and it leans on a handful of pantry staples rather than anything specialized. It is generous enough to feel like a treat, yet simple enough to become a regular in the rotation for a family dinner or a quiet meal at home.
Soaked cashews do what cream would. Once softened in hot water and blended, they break down into a creamy base, carrying richness the way cream would. Coconut milk adds body and a round, silky mouthfeel, while nutritional yeast brings the savory, faintly cheesy depth that makes the sauce taste like more than the sum of its parts. Gently cooking the minced garlic in olive oil first builds a mellow, sweet backbone, and a squeeze of lemon juice keeps the whole thing bright instead of heavy. Finishing with starchy pasta water is what emulsifies everything into a glossy coat that clings.
Real richness and real substance both show up here. The cashews and olive oil supply healthy fats that make the sauce feel indulgent and keep you full, while the nutritional yeast and cashews together add plant protein. The pasta gives steady, comforting energy, and the garlic and lemon carry big flavor without a long ingredient list. It tastes richer than its ingredient list suggests, which is the whole point of a dairy-free cream sauce.
Ingredients
- 4 cups cooked pasta
- 1 cup raw cashews, soaked
- 1/2 cup light coconut milk
- 1/4 cup nutritional yeast
- 4 cloves garlic
- 2 tbsp olive oil
- 1 tbsp lemon juice
- 3/4 tsp salt
Instructions
- Soak the cashews: Place the raw cashews in a heatproof bowl and cover them with boiling water. Let them sit until softened and plump, about 15 minutes, then drain. This softening is what lets them blend into a completely smooth, cream-like sauce.
- Cook the pasta: Bring a large pot of well-salted water to a rolling boil. Add the pasta and cook until tender with just a slight bite in the center. Before draining, scoop out and reserve a mug of the starchy cooking water, then drain the pasta and set it aside.
- Blend the sauce: Add the drained cashews, coconut milk, nutritional yeast, lemon juice, salt, and water to a blender. Blend on high until the mixture is completely smooth, silky, and pourable, stopping to scrape down the sides once or twice so no gritty bits remain.
- Warm the garlic: Peel and finely mince the garlic. Warm the olive oil in a large skillet over medium-low heat, add the garlic, and cook gently, stirring often, until fragrant and pale gold, about 1 to 2 minutes. Keep the heat low so the garlic sweetens rather than browns and turns bitter.
- Warm the sauce: Pour the blended sauce into the skillet with the garlic and stir to combine. Warm it through over low heat, stirring, until it steams and thickens slightly, about 2 to 3 minutes. Do not let it boil hard, which can make it grainy.
- Toss and serve: Add the hot drained pasta to the skillet and fold gently until every strand is coated. Loosen the sauce with a splash of the reserved pasta water, a little at a time, until it turns glossy and clings to the pasta. Serve right away while hot.
Variations
- Roasted broccoli: Toss broccoli florets with olive oil and salt and roast at 425°F (220°C) until the edges are browned and crisp-tender, then fold them in with the pasta for a green, slightly charred contrast to the creamy sauce.
- Mushroom: Slice mushrooms and sauté them in a little olive oil until deeply golden and their moisture has cooked off, then stir them through. They add a meaty, savory bite that plays well with the garlic.
- Sun-dried tomato and basil: Fold in chopped sun-dried tomatoes and a handful of torn fresh basil at the end for pops of tangy sweetness and a fresh, herbal lift against the rich sauce.
- Spicy garlic: Add a pinch of red pepper flakes to the oil while the garlic cooks for a gentle heat that builds through the sauce; adjust the amount to your tolerance.
- Extra green protein: Stir shelled edamame or white beans into the finished pasta to warm through; this adds legumes and makes the plate heartier and higher in protein.
Storage & Leftovers
Store leftovers in an airtight container in the refrigerator for up to four days. The sauce will thicken and set as it chills, which is normal.
To reheat, warm the pasta gently in a skillet or saucepan over low heat, adding a splash of water or plant milk and stirring as it loosens back into a smooth, glossy sauce. Avoid high heat or long microwaving, which can make the cashew sauce break or turn grainy; if microwaving, use short bursts and stir between them.
To get ahead, make the blended sauce up to three days in advance and keep it in a jar in the refrigerator. When you are ready to eat, cook fresh pasta, warm the garlic in oil, and stir the sauce in to finish. The sauce also freezes well on its own for up to three months; thaw overnight and whisk to bring it back together.
Notes & Tips
- A high-speed blender is your friend: The smoother you blend, the more luxurious the sauce. A high-speed blender gives the glossiest result; if yours is less powerful, soak the cashews longer in hot water so they break down fully with no grit.
- No soak time? Use a shortcut: If you are short on time, simmer the raw cashews in water for about ten minutes instead of soaking. They will soften enough to blend smooth.
- Nutritional yeast is the savory secret: This is what gives the sauce its cheesy, umami depth. Start with less and taste; add more if you want a stronger savory note, since brands vary in intensity.
- Save more pasta water than you think: The sauce firms up fast off the heat, so keep extra starchy water on hand to loosen it at the table. It reheats beautifully with just a splash stirred in.
- Balance the brightness: Taste before serving and add a few extra drops of lemon juice if it feels heavy, or a pinch more salt if it tastes flat. That final adjustment is what makes it sing.
- Serve it with something green: A simple side of peppery arugula dressed in olive oil and lemon, or a plate of roasted vegetables, cuts the richness and rounds out the meal.
Nutrition & Mindful Eating
- The cashews, the coconut milk and the pasta work together here. The nuts give the sauce its body, the coconut milk loosens it to a pourable cream, and the whole wheat pasta underneath has enough texture to hold up to all of it.
- Cashews are what make this sauce a sauce. Soaked and blended, they go completely smooth and turn glossy in the pan, and the unsaturated fat and magnesium they carry come along inside that richness.
- Whole wheat pasta has a nutty, slightly chewy bite that keeps its shape under a heavy sauce, and the fiber in the bran is a good part of why this bowl settles in and stays with you.
- Garlic goes into warm oil first, so it turns sweet and mellow before the cream ever reaches the pan, and the lemon juice stirred in at the end is what lifts the whole bowl and stops it from tasting flat.
- Nutritional yeast melts into the sauce with a toasted, deeply savory flavor that ends up being the backbone of the dish, and it brings B vitamins along with that savoriness.
- As you eat, notice how the sauce coats the back of the spoon and how the lemon arrives just after the richness, and let yourself slow down enough to feel the bowl doing its work.
Frequently Asked Questions
Can I make this without a high-speed blender?
Yes. Soak the cashews longer in hot water, or simmer them for about ten minutes, so they are very soft. A regular blender or even an immersion blender will then get them smooth, though you may need to blend a bit longer and scrape the sides more often.
Will this taste like coconut?
Not noticeably. The light coconut milk adds creaminess and body, but the garlic, nutritional yeast, and lemon dominate the flavor, so the finished sauce tastes savory and garlicky rather than tropical.
My sauce got too thick after sitting. How do I fix it?
That is normal, since the cashews continue to set as the sauce cools. Warm it gently and stir in a splash of the reserved pasta water, plain water, or plant milk a little at a time until it turns glossy and pourable again.
Can I use roasted or salted cashews instead of raw?
Raw cashews give the cleanest, creamiest, most neutral result. Roasted cashews will tint the sauce beige and add a toasty flavor, and salted ones will throw off the seasoning, so reduce the added salt and taste as you go if that is all you have.
