To prepare a vegan cashew alfredo sauce recipe, first you'll need to gather your ingredients. You can find these ingredients at your local grocery store, or you can make them at home. To make the sauce, mix the following ingredients together: 14 cup chopped parsley 2 tablespoons chopped thyme 1 tablespoon kosher salt 1/2 teaspoon ground black pepper 1 tbsp. olive oil 1/2 cup water 1 cup frozen peeled and halved pistachios (optional) 1 teaspoon dried oregano 2 teaspoons ground nutmeg 1/4 teaspoon garlic powder 1/8 teaspoon red pepper flakes Instructions: Heat the oil over medium-high heat. Add the garlic and saute until fragrant, about 1 minute. Stir in the shredded carrots and cook, stirring frequently, until the vegetables are just tender, 3 to 5 minutes. Remove the pan from the heat and add the almond milk. Simmer, whisking constantly, for 5 to 10 minutes or until thickened. Taste and adjust seasonings, if needed. Serve immediately.
