Step-By-Step Instructions for Creamy Red Pepper Alfredo Pasta
Step 1: Soak the Nuts
Begin by placing 1 cup of raw cashews or macadamia nuts in a bowl, covering them completely with water. Let them soak for 6-8 hours or overnight to achieve the creamiest texture. Once soaked, drain the nuts and pat them dry, ensuring they’re ready for blending into your creamy red pepper Alfredo pasta.
Step 2: Blend All Ingredients
In a high-speed blender, combine the soaked nuts with 1 roasted red bell pepper, 1 cup of water, 1/4 cup of nutritional yeast, 1 teaspoon of onion powder, 1/4 teaspoon of ground turmeric, and salt to taste. Blend on high until the mixture is completely smooth and velvety, which should take about 1-2 minutes. This creamy base will be the heart of your Alfredo sauce!
Step 3: Heat the Sauce
Transfer the blended sauce into a medium-sized pot and set it over low to medium heat. Stir occasionally, allowing the sauce to warm through for about 5-7 minutes. This gentle heating ensures that the flavors meld beautifully as you prepare your pasta, which should be cooked simultaneously according to package directions.
Step 4: Cook the Pasta
While the sauce warms, bring a pot of salted water to a boil and add 10 oz of your favorite pasta. Cook according to the package instructions until al dente, approximately 8-12 minutes, depending on the type. Once done, drain the pasta thoroughly, but do not rinse it to retain some of the starch that helps the sauce adhere.
Step 5: Combine Pasta and Sauce
Carefully add the drained pasta into the pot with your creamy red pepper Alfredo sauce. Toss well to coat the pasta, ensuring each strand is covered in the exquisite sauce. Adjust salt and pepper to your taste, sprinkling in ground nutmeg if desired to enhance the flavors of the creamy red pepper Alfredo.
Step 6: Add Optional Ingredients
For a heartier dish, consider stirring in cooked vegetables or proteins such as sautéed spinach, steamed broccoli, or chickpeas at this stage. Let everything combine for another 2-3 minutes over low heat, allowing flavors to meld together beautifully, ensuring your creamy red pepper Alfredo pasta is as delicious as possible.
Step 7: Serve and Enjoy
Once combined, remove from heat and serve your creamy red pepper Alfredo pasta immediately. For a delightful finish, garnish with fresh herbs or additional nutritional yeast. This dish not only looks appetizing but is also a warm, comforting meal that’s perfect for sharing or enjoying by yourself.

How to Store and Freeze Creamy Red Pepper Alfredo Pasta
Fridge: Store leftovers in an airtight container for up to 5 days. This allows the flavors to meld while keeping the sauce creamy and delicious.
Freezer: For longer storage, freeze the creamy red pepper Alfredo sauce in an airtight container for up to 3 months. When ready to use, thaw in the fridge overnight.
Reheating: Gently reheat the sauce on the stove over low heat, stirring frequently to maintain its creamy texture. Add a splash of water or plant-based milk if it thickens too much.
Avoid Freezing with Pasta: It’s best to store the sauce separately from the pasta to avoid texture changes. When reheating, simply mix the desired amount of sauce with freshly cooked pasta.
