Vegan Fettuccine Alfredo
Equipment
- 1 blender
- 1 Large pan
Ingredients
- 4 ounces fettuccine or preferred gluten-free pasta
- 1 tablespoon extra virgin olive oil
- 5 ounces mushrooms sliced
- ½ cup cherry tomatoes halved
- 1 cup vegan cashew Alfredo sauce
- 1 handful baby spinach
Instructions
- Prepare the Cashew Alfredo Sauce: Before cooking the pasta, ensure your vegan cashew Alfredo sauce is ready. If using a homemade version, blend soaked cashews with plant-based milk, nutritional yeast, garlic, lemon juice, salt, and a pinch of pepper until completely smooth and creamy. Taste and adjust seasonings, keeping in mind that the sauce will thicken slightly when heated. Set aside while you cook the pasta.
- Boil the Pasta Perfectly: Bring a large pot of salted water to a rolling boil. Add your fettuccine or preferred gluten-free pasta and cook according to the package instructions until al dente—tender but still slightly firm to the bite. Before draining, reserve about ¼ cup of the starchy pasta water, which will help the Alfredo sauce cling beautifully to the noodles. Drain the pasta and set aside.
- Sauté the Mushrooms: Heat 1 tablespoon of extra virgin olive oil in a large pan over medium heat. Once shimmering, add the sliced mushrooms. Sauté them gently, stirring occasionally, for 5–6 minutes, or until they release their moisture and begin to turn golden brown. This step enhances their natural umami flavor, which adds depth to the sauce.
- Cook the Cherry Tomatoes: Add the halved cherry tomatoes to the pan with the mushrooms. Stir occasionally and cook for about 2–3 minutes, just until the tomatoes start to soften and release a little juice. Be careful not to overcook—they should retain their shape and a fresh, vibrant color, adding a subtle sweetness to the dish.
- Incorporate the Alfredo Sauce: Pour the prepared cashew Alfredo sauce into the pan with the sautéed vegetables. Stir gently to combine, creating a smooth, creamy base. If the sauce feels too thick, gradually add a tablespoon or two of the reserved pasta water, stirring continuously, until it reaches a silky, pourable consistency that will coat the pasta evenly.
- Add Fresh Baby Spinach: Toss a handful of fresh baby spinach into the sauce. Stir for 1–2 minutes until the leaves begin to wilt. The spinach not only adds vibrant color but also boosts the dish with fiber, iron, and a fresh, mild flavor that balances the richness of the Alfredo sauce.
- Combine Pasta and Sauce: Add the cooked fettuccine to the pan with the vegetables and sauce. Using tongs or a large spoon, gently toss everything together until every noodle is thoroughly coated with the creamy sauce. If necessary, add a splash more pasta water to loosen the sauce and ensure it clings perfectly to each strand.
- Season and Taste: Taste the pasta and adjust the seasoning as needed. Add a pinch of salt, freshly ground black pepper, or a squeeze of lemon juice to enhance brightness and flavor. Stir well and ensure the seasoning is evenly distributed throughout the dish.
- Plate and Serve Beautifully: Divide the creamy vegan fettuccine Alfredo onto plates or bowls. For an extra touch, garnish with fresh herbs such as parsley or basil, a sprinkle of nutritional yeast, or a few toasted pine nuts if desired. Serve immediately while hot and creamy for the ultimate comfort meal experience.
- Enjoy and Store Leftovers: Savor each bite of this rich, plant-based Alfredo. If you have leftovers, allow the pasta to cool slightly, then transfer it to an airtight container. Store in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave with a splash of plant-based milk to restore creaminess.
Notes
- Pasta Choice Matters: You can use any type of fettuccine or long pasta, including gluten-free varieties or zucchini noodles, for a lighter option. Just adjust cooking times accordingly.
- Reserve Pasta Water: Always save a small amount of starchy pasta water when draining. It helps the sauce cling to the noodles and enhances the overall creaminess.
- Vegetable Variations: Feel free to swap mushrooms or cherry tomatoes with your favorite seasonal vegetables, such as asparagus, peas, or bell peppers. This adds variety and nutrients to the dish.
- Sauce Consistency: If the cashew Alfredo sauce is too thick, gently thin it with a little plant-based milk or reserved pasta water. Conversely, if too thin, simmer briefly to thicken.
Chef’s Secrets: Elevate Creamy Alfredo Flavor

For extra richness, a small squeeze of lemon juice brightens the sauce without overpowering it.
Always stir the pasta gently when combining with the sauce to ensure every strand is coated evenly, creating a luxurious, restaurant-quality finish.
