• Try substituting macadamia nuts with almonds if desired, but soak them longer for a smoother texture.

• For a dairy-free version, use nutritional yeast instead of Parmesan cheese.

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)

For Serving

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

Instructions

1. Soak the nuts: Place the cashews or macadamia nuts in a cereal bowl and cover with water. Let them soak for 6-8 hours to soften, which helps create a creamy texture when blended. After soaking, drain the nuts fully and pat them dry with a clean towel.
2. Prepare the sauce: In a food processor or high-speed blender, combine the soaked nuts, red bell pepper, 1/2 cup water, nutritional yeast or Parmesan cheese, salt, onion powder, turmeric, and optional nutmeg. Blend until the mixture is completely smooth and creamy, ensuring no lumps remain.
3. Cook the pasta: In a large pot, bring salted water to a boil and cook the pasta according to the package directions until al dente. Drain the pasta thoroughly, but avoid rinsing it so the sauce adheres better.
4. Heat the sauce: Pour the blended sauce into a pot and gently heat it over medium-low heat until warmed through, stirring frequently to prevent sticking. Be careful not to boil the sauce to preserve its creamy texture.
5. Combine and serve: Pour the warm Alfredo sauce over the drained pasta or your chosen base. Stir in any optional grilled or roasted vegetables or beans for added flavor and texture. Season with additional salt and pepper if desired, then serve immediately for the best taste and texture.

Notes

• Soaking nuts overnight ensures a smooth and creamy sauce texture.
• Using roasted red bell pepper adds a smoky depth of flavor; raw peppers give a fresher, lighter taste.
• Nutritional yeast provides a cheesy, vegan-friendly flavor, while Parmesan cheese adds richness for non-vegan versions.
• This sauce pairs well with gluten-free pasta or spiralized vegetables for a lighter option.
• Store leftover sauce in an airtight container in the fridge for up to 3 days; reheat gently on the stovetop.
• You can substitute macadamia nuts for cashews if preferred, adjusting soaking time as needed.
