Ingredients for making Easy Vegan Pasta Sauce.

Roasted sweet potato is a healthy way to add creaminess and a touch of sweetness to this pasta sauce. It's rich in vitamins A and C, fiber, and potassium.
Blended white beans add protein, iron, and fiber to this sweet potato tomato sauce. Plus, they give it a delicious creamy texture.
Nutritional yeast is high in vitamin B₁₂, and is a complete protein. It gives this dish a cheesy taste, similar to parmesan cheese.
Cashews make this vegan pasta sauce extra creamy. They are a good source of heart healthy fats, and a moderate source of protein.

💡 Expert Tips

Cut the veggies according to the recipe to minimize the cooking time. Larger veggies take longer to roast.

Soak the cashews for 20 minutes in boiling water if you do not own a high-speed blender. This makes them easier to blend.

High-speed blenders are a game changer when it comes to blending soups, sauces, and nuts. It is a worthwhile investment if you plan on eating more plant-based meals. Research different high-speed blenders based on reviews, and choose the best one you can afford.
