Pasta? Check. Roasted tomatoes? Check. Creamy vegan cashew sauce? Absolutely CHECK! This recipe is so simple, but it delivers big on both flavor and creaminess. Make the cream sauce ahead of time and dinner is ready in no time.

One of my food weaknesses is a pasta tossed with cream sauce. The richness from the sauce always feels like a satisfying dinner, and I’ve yet to meet a vegetable that doesn’t go well when paired with a creamy sauce.

Of course, when cooking a vegan meal, using heavy cream is out. For these times, cashew cream is my go-to replacement.

What Is Cashew Cream Sauce?

The soft texture of the cashews puree into the creamiest of sauces to the point of where I don’t even miss the cream. The sauce is similar in texture to Alfredo and comes together by simply soaking raw cashews in a bit of water. Add the fresh herbs, and this sauce is up there as a favorite of mine.

Best of all, this is a great year-round sauce to use with any pasta recipe. Make this recipe with roasted butternut squash in the fall or some pan-fried asparagus in the spring. Still delicious.
