Don't like Cashews? - While cashews work the best if you don't love them, I have had luck subbing in raw slivered almonds into this sauce. I would just make sure to soak them a bit longer.
Nutritional Yeast - I'm not a fan personally, but if you are, you can add it to this sauce for some extra "cheesy" flavor. If you add it, I would stick with about ¼-⅓ of a cup.
Add Vegetables - I am a huge fan of adding things like sauteed mushrooms, spinach, kale, and even broccoli to alfredo. Feel free to add what you like.
Want more spice? Add in a bit of your favorite Italian seasoning for a bit more flare. You can even add a bit of cajun spice to make turn this into a cajun alfredo.
How long will this sauce keep?
This sauce is best fresh but it will keep in the fridge for 2-3 days.
Can you freeze this dairy-free alfredo sauce?
While I would say no with traditional alfredo sauce, this one is different. This sauce actually freezes really well. It works best to freeze it by itself before adding it to pasta. When you are ready to use it, just thaw it overnight in the fridge or warm it up on the stove over medium heat.
More ways to use this sauce
Add it to some rice for a bowl of creamy rice, over your favorite veggies, or even as a base for the perfect dairy-free alfredo pizza sauce. The possibilities are endless.
