Quick 15-Minute Creamy Vegan Pasta Sauce

This creamy vegan pasta sauce is the kind of recipe that makes a weeknight dinner feel a little more put together, without any extra work. Raw cashews blend into a silky, savory sauce that coats every strand of pasta.

It comes together in about 15 minutes, start to finish. No dairy, no long soak, just a blender and a pan.

Why This Sauce Stays in My Weeknight Rotation

The texture is the selling point. It is smooth and rich, just like a dairy-based cream sauce, but without any of the heaviness. Nutritional yeast gives it a savory, slightly cheesy depth, while lemon brightens everything up.

I keep a jar of this sauce in the fridge and toss it with pasta for quick lunches, or thin it out as a dipping sauce for veggies. It works with nearly any pasta shape, and it never breaks when you reheat it.

Ingredients

• 1 cup raw cashews: plain, unsalted, and unroasted. No soak needed if you have a high-speed blender.
• 1 cup fresh water: plus more for soaking.
• 2 tbsp nutritional yeast: adds a savory, cheese-like flavor.
• 1 tbsp lemon juice: fresh gives the best brightness.
• 1 garlic clove: use a small one or a roasted clove for a mellower taste.
• ½ tsp salt: adjust to your taste at the end.
• ¼ tsp onion powder: rounds out the savory notes.

Variations and Swaps

• Nut-free: swap the cashews with raw sunflower seeds. Soak them the same way.
• Herby: blend in a handful of fresh basil or parsley after the sauce is smooth.
• A little heat: add a pinch of red pepper flakes or a small seeded jalapeño.
• Tangier finish: stir in an extra teaspoon of lemon juice right before serving.

Creamy Vegan Pasta is an easy way to put this sauce to good use.

How to Make Creamy Vegan Pasta Sauce

Step 1: Soak the Cashews

Place the 1 cup of raw cashews in a heatproof bowl and cover them with boiling water. Let them sit for 10 minutes, then drain. If your blender is very powerful, you can skip this and use the dry cashews straight from the bag.

Step 2: Blend Into a Creamy Sauce

Add the drained cashews, 1 cup fresh water, 2 tbsp nutritional yeast, 1 tbsp lemon juice, the garlic clove, ½ tsp salt, and ¼ tsp onion powder to a blender. Blend on high until completely smooth, about 1 to 2 minutes. Stop once to scrape down the sides, then taste and add a pinch more salt if it needs it.

Step 3: Toss and Serve with Pasta

While the cashews soak, bring a large pot of salted water to a boil and cook 12 oz of dry pasta until al dente. Before draining, scoop out about ½ cup of the starchy pasta water. Return the hot drained pasta to the pot, pour the sauce over it, and add a splash of the reserved pasta water. Toss over low heat for about 1 minute, just until the sauce is warmed through and clings to every piece. Serve in bowls with a crack of black pepper and a drizzle of good olive oil.

A Few Tips Before You Start

• Soak the cashews in boiling water right when you start heating the pasta pot. By the time the pasta is done, the cashews are soft and ready.
• Use the leftover sauce as a spread for sandwiches or a base for creamy salad dressings. Just thin it with water or lemon juice.
• If the sauce thickens in the fridge, whisk in a splash of plant milk or cold water when you reheat it.
• A pinch of turmeric blended in gives the sauce a pale yellow color that looks inviting on the plate.

Scale the sauce to your batch size:

Storing Leftovers

Refrigerate: Keep the sauce in a sealed jar for up to 5 days. It will thicken as it chills. Reheating: Warm it gently on the stove with a splash of water or plant milk, stirring often so it stays smooth. You can also use it cold as a spread or dip.

What to Serve with Creamy Vegan Pasta Sauce

Long pasta like fettuccine or linguine holds the sauce especially well, but short shapes like penne work too. A side of roasted broccoli or blistered cherry tomatoes gives you a little char to contrast the creaminess. Garlic bread on the side never hurts.

Frequently Asked Questions

Can I use almonds instead of cashews?

You can, but the sauce will be less smooth and more gritty. Blanched almonds give the best shot at a creamy texture.

What is a good nut-free option?

Raw sunflower seeds work nicely. Soak them the same way and expect a slightly earthier taste.

Why did my sauce turn out grainy?

A lower powered blender might not get raw cashews completely smooth. Soak them longer, up to an hour in cool water, and blend for an extra minute.

Can I freeze this sauce?

Yes. Freeze it in a sealed container for up to 3 months. Thaw overnight in the fridge, then whisk it back together as it warms.
