Healthy Homemade Alfredo Sauce (Lower Fat & Full Flavor)
This lower fat alfredo sauce recipe takes a plant-powered twist by using soaked cashews and unsweetened soy milk as the creamy base. Nutritional yeast adds the essential “cheesy” flavor, while garlic, onion, and lemon juice provide layers of depth and brightness.
It’s an ideal option for an easy weeknight dinner, offering a quick, satisfying, and wholesome meal solution.
As a Flexitarian Dietitian, Here’s Why This Recipe Stands Out
- Simple ingredients for a healthier Alfredo sauce that’s quick and easy to make with items from your local grocery store.
- Healthy recipe that’s plant-powered with creamy soaked cashews and protein-packed unsweetened soy milk.
- Delicious recipe with bold flavor thanks to nutritional yeast, garlic, lemon juice, and sautéed onion.
- Lower fat Alfredo sauce that’s rich, creamy, and satisfying without relying on heavy cream or butter.
- Versatile and meal-prep friendly. Make it ahead of time and enjoy it fresh or as leftovers the next day.
This sauce isn’t just a “healthier version” of Alfredo, it’s a completely elevated recipe that’s plant-forward, protein-packed, and rich in flavor. It’s perfect for anyone looking for a nourishing, creamy option that’s as comforting as the classic.
Ingredients
- Raw Cashews (3/4 cup): Soaked overnight or in hot water for at least 30 minutes. Soaking softens the cashews, making it easier to blend into a creamy sauce. Cashews bring healthy fats to the recipe, supporting heart health and satiety.
- Unsweetened Soy Milk (1 1/2 cups): Soy milk is a nutritional powerhouse — it’s naturally high in protein, which isn’t something you’d normally get from traditional Alfredo sauce. The protein keeps you fuller for longer!
- Nutritional Yeast (3 tablespoons): This is the “secret weapon” for cheesy flavor in vegan and plant-based recipes. As a dietitian, I love recommending it because it’s rich in B12, a nutrient that’s crucial for energy production, especially for those following a plant-forward diet.
- Lemon Juice (2 tablespoons): Brightens and balances the richness of the sauce. It’s also a source of vitamin C, which can aid in the absorption of certain nutrients like iron when paired with plant-based meals.
- Onion (1 medium, finely chopped):Cooking onion with olive oil builds a flavorful base for the sauce. It also provides prebiotics, which support gut health by feeding beneficial gut bacteria. I do not recommend swapppign the fresh onion for onion powder. The sauteed onion adds bulk and texture to the sauce.
- Garlic Clove (4 cloves, minced): Garlic’s bold flavor is essential in any Alfredo recipe. Garlic also contains allicin, which has been linked to heart health benefits. For a milder garlic flavor, you can swap in 1/2 teaspoon of garlic powder. Option to use 1/2 tsp garlic powder.
- Olive Oil (1 tablespoon, plus extra for sautéing): Olive oil is a heart-healthy fat that’s rich in antioxidants and monounsaturated fats. It adds richness to the sauce while enhancing the flavors of onion and garlic.
- Pasta water or water: optional to use a little bit or more for thinning
Step-By-Step Instructions
- Soak the Cashews: If you haven’t already, soak the raw cashews overnight or in hot water for at least 30 minutes. Drain and set aside. (RD Tip: If you’re short on time, boiling water works in a pinch — soak for 30 minutes to achieve a similar result.)
- Sauté the Onion and Garlic: Heat a drizzle of olive oil in a pan over medium-high heat. Add the chopped onion and sauté for 3-5 minutes until soft and translucent. Add the minced garlic and cook for another minute. Remove from heat. (RD Tip: I add the garlic seperately to ensure it doesn’t burn.)
- Blend the Cashew Sauce: In a high-speed blender, combine the soaked cashews, unsweetened soy milk, nutritional yeast, lemon juice, sautéed onion and garlic, salt, black pepper, and nutmeg (if using). Blend on high until the sauce is completely smooth and creamy. Taste and adjust seasonings as needed. (RD Tip: If you’re adjusting the consistency, add water (or soy milk) a tablespoon at a time, blending between additions to avoid over-thinning.)
Serving Ideas & Flexitarian Tips
My version of Alfredo sauce is as versatile as it gets.
Use it to create these delicious healthier recipes:
- Pasta Night Upgrade: Toss it with fettuccine or your favorite pasta and garnish with fresh parsley, for a comforting, creamy fettuccine alfredo. Using protein pasta in this classic dish is a great way to boost the protein content of the meal and make it more filling.
- Vegetable Casseroles: Use it as a sauce base for baked casseroles, like a dairy-free “creamy broccoli bake.”
- Grain Bowls: Drizzle it over whole grains (like quinoa or farro) and roasted veggies.
- Pizza Sauce: Top it with Italian seasoning, fresh vegetables, and plant-based proteins like beans or tofu. Finish with vegan or traditional mozzarella and a sprinkle of shredded Parmesan cheese.
- Dip for Veggies: Serve thick and as a dip for roasted veggies or crackers.
Why This Recipe Works for Flexitarians
As a flexitarian dietitian, I’m always looking for recipes that meet these criteria:
- Flavor: This sauce delivers bold, cheesy, umami-rich flavor that’s just as satisfying as traditional Alfredo.
- Nutrition: Packed with plant-based protein, heart-healthy fats, and essential vitamins like B12, it’s a functional way to incorporate whole foods into your diet. This sauce is lower in fat than traditional Alfredo sauces.
- Sustainability: Plant-based meals like this are lower in environmental impact, making them a great choice for those who want to eat more sustainably.
Common Questions & RD Answers
1. Can I make this healthy alfredo sauce recipe ahead of time?
Yes! This sauce keeps well in the refrigerator for up to 5 days. Reheat on the stovetop or microwave, adding a splash of water or soy milk to thin if needed.
2. Can I freeze it?
Yes. Store it in an airtight container and freeze for up to 3 months. Thaw overnight in the fridge and re-blend or whisk to bring it back to its smooth consistency.
3. What if I’m allergic to nuts?
Swap the cashews for sunflower seeds, tofu, or white beans. The texture will be a little different, but it’s still delicious and creamy.
4. What if I’m allergic to soy?
If you’re allergic to soy, you can substitute soy milk with oat milk, almond milk (if not allergic to nuts), coconut milk, or other non-dairy milk alternatives. Double-check any store-bought non-dairy milks for potential cross-contamination with soy.
4. Can I make this oil-free?
Yes! Sauté the onion and garlic in a splash of water or veggie broth instead of olive oil.
