  • Total Time: Approximately 6 hours 20 minutes (including soaking) or 20 minutes active
  • Yield: 5 servings

Ingredients

Sauce Ingredients

  • 1 red bell pepper (raw or roasted)
  • 1/2 cup water
  • 1/2 cup raw cashews (or macadamia nuts)
  • 1/4 cup nutritional yeast (or Parmesan cheese)
  • 1 tsp salt
  • 2 tsp onion powder
  • 1/2 tsp ground turmeric
  • 1/8 tsp ground nutmeg (optional)

Pasta and Optional Add-ins

  • 10 oz pasta (or spaghetti squash or vegetables)
  • Optional grilled or roasted veggies (beans, etc.)

Instructions

  1. Soak Nuts: Place the raw cashews or macadamia nuts in a cereal bowl and cover them with water. Let them soak for 6-8 hours to soften, then drain completely and pat dry.
  2. Blend Sauce: In a food processor or high-speed blender, combine the soaked nuts, red bell pepper, 1/2 cup water, nutritional yeast (or Parmesan), salt, onion powder, turmeric, and nutmeg (if using). Blend until the mixture is completely smooth and creamy.
  3. Cook Pasta: Cook the pasta in a separate pot of salted boiling water according to the package instructions until al dente. Drain the pasta thoroughly but do not rinse.
  4. Heat Sauce: Transfer the blended sauce to a pot and gently heat it over medium heat, stirring occasionally, until it reaches the desired serving temperature.
  5. Combine and Serve: Pour the warm red pepper Alfredo sauce over the drained pasta. Season with additional salt and pepper if desired, and stir in any optional cooked vegetables, beans, or other add-ins to suit your taste. Serve immediately.

Notes

  • Soaking the nuts is essential to achieving a creamy texture in the sauce.
  • Roasting the red bell pepper before blending can add a smoky depth of flavor.
  • The sauce works well with traditional pasta, spaghetti squash, or steamed vegetables for a low-carb option.
  • Nutritional yeast can be substituted with Parmesan cheese if not following a vegan diet.
  • Add turmeric and nutmeg for subtle warmth and complexity.
