Step‑by‑Step Instructions for Creamy Red Pepper Alfredo Pasta
Step 1: Soak the Nuts
Begin by placing your raw cashews or macadamia nuts in a bowl and covering them with water. Let them soak for 6 to 8 hours at room temperature. This step is essential for achieving that velvety texture in your Creamy Red Pepper Alfredo Pasta, so make sure the nuts become soft and slightly plump.
Step 2: Blend the Sauce
Once the nuts are soaked, drain and rinse them before adding them to a high-speed blender. Combine the softened nuts with one chopped red bell pepper, ½ cup of water, nutritional yeast, salt, onion powder, turmeric, and nutmeg. Blend everything on high for about 1-2 minutes or until the mixture is completely smooth and creamy, ensuring no lumps remain.
Step 3: Heat the Sauce
Transfer the silky red pepper Alfredo sauce into a medium saucepan. Over low heat, warm the sauce for about 5-7 minutes, stirring occasionally to prevent sticking. As it heats, you’ll notice the sauce thickening and becoming even more aromatic, perfectly ready to coat your pasta or vegetables.
Step 4: Cook the Pasta
While the sauce is warming, bring a pot of salted water to a boil and cook your pasta according to the package instructions, usually around 8-12 minutes. Stir occasionally until the pasta reaches your desired tenderness, visualizing it becoming al dente, ready to soak up that delicious Creamy Red Pepper Alfredo.
Step 5: Combine and Serve
Once the pasta is cooked, drain it well without rinsing, allowing the starch to help bind the sauce. Pour the warm red pepper Alfredo sauce over the pasta, gently tossing to combine until every strand is beautifully coated. Feel free to add any optional grilled vegetables or beans for an extra burst of flavor and nutrition before serving.

How to Store and Freeze Creamy Red Pepper Alfredo Pasta
Fridge: Store any leftover creamy red pepper Alfredo pasta in an airtight container for up to 5 days. Reheat gently on the stove or microwave, stirring well to maintain creaminess.
Freezer: For longer storage, freeze the sauce separately in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: When reheating, add a splash of water or vegetable broth to the sauce to help restore its creamy texture. Stir frequently to prevent sticking.
Airtight Storage: To keep flavors intact and prevent freezer burn, ensure your containers are well-sealed. This will help maintain the delicious taste of your creamy red pepper Alfredo pasta.
