Step 1 (Boil Pasta): Bring a large pot of salted water to a boil. Cook the macaroni according to package instructions until al dente (approx. 7–10 minutes). Drain and set aside.
Step 2 (Boil Veggies & Soak Cashews): Boil the peeled potato and carrot chunks in a small pot for 10–15 minutes until fork-tender. Simultaneously, soak raw cashews in boiling hot water for 15 minutes.
Step 3 (Blend Cheese Sauce): In a high-speed blender, combine the boiled potato, boiled carrot, drained soaked cashews, onion, garlic, olive oil, nutritional yeast, water, coconut milk, lemon juice, salt, pepper, and a pinch of turmeric. Blend on high until completely smooth and creamy.
Step 4 (Combine Sauce & Pasta): Add the cooked macaroni back to your pot or a large bowl. Pour the velvety blended cheese sauce over the pasta.
Step 5 (Toss & Adjust): Stir thoroughly until every noodle is evenly coated. Taste and adjust seasoning with extra salt, pepper, or lemon juice as needed.
Step 6 (Serve Hot): Transfer to serving bowls, garnish with fresh parsley or extra nutritional yeast, and serve hot!
