Author:
Recipe type: Sauce
Cuisine: American
Serves: 4 to 6 servings
Ingredients
  • ¼ cup raw cashews (see the Nut Options below)
  • 2 cups water, divided
  • ¼ cup diced tomatoes
  • ¼ cup nutritional yeast flakes, or to taste
  • 2 tablespoons non-GMO cornstarch or arrowroot starch
  • ½ tablespoon lemon juice, or to taste
  • 1 to 1½ teaspoons sea salt, to taste
  • ¼ teaspoon garlic powder
  • ½ teaspoon onion powder
Instructions
  1. Grind the cashews in a spice grinder or small food processor until powdered.
  2. Pour the cashew powder into your blender. Add the 1 cup water, tomatoes, nutritional yeast, starch, lemon juice, 1 teaspoon salt, onion powder, and garlic powder. Puree until smooth. Add the remaining 1 cup water and briefly blend to combine.
  3. Pour the mixture through a sieve into a saucepan. Place the pan over medium heat, and cook, stirring constantly, until the sauce thickens, about 5 minutes. Taste test and add more salt, if needed.
Notes
Nut Option: Cashews produce the creamiest results, and we think they provide the best flavor. But you can substitute almonds (preferably blanched) or macadamia nuts, in a pinch. For nut-free, sunflower seeds work fairly well.

  1. Hi. I glanced at a free cheese alternatives but am wondering if they will help me leave dairy cheese alone. I LOVE cheese: American, Cheddar, Mozzarella, etc. I overuse it n my omelets, sautéed spinach, kale, onion concoction, and so forth. Are there alternatives to that if not aforementioned?! Thank you

    Hi, I live in South Africa and have no idea what Nutritional Yeast is…? My daughter has dairy and soy allergies as well as peanuts and most legumes. I’m interested in your cheese substitutes, not so much for her but for me! When I’m breastfeeding (nursing) I have to be on her allergy-free diet. We have instant dry yeast that comes in sachets for breadmaking but I’m pretty sure that’s not what you’re referring to. Is it called by any other name?

    • Hi Nicole, nutritional yeast is quite different from the yeast that you would use in breadmaking. It is an inactive yeast that has a pungent almost cheesy flavor and is typically fortified with B vitamins (hence the “nutritional” name). It comes in flakes or powder that are a mustardy yellow color and quite lightweight – not nearly as heavy as active yeast. I’m not sure where you could source it in South Africa – perhaps online or from a natural food store?
