How To Make Vegan Alfredo Sauce
The full recipe & ingredients list are below, but here you’ll find a quick overview for making this recipe perfectly, along with useful tips and info!
Soak the raw cashews in hot water. I pour hot water over mine and let them sit for 30-60 minutes while I do other things. (This is optional but helps positively ensure a smooth sauce.
Drain the cashews and add to a high-speed blender along with other ingredients, and blend on high speed. (See the top tips if you don’t have a high-speed blender!)
Toss with the hot, cooked pasta and serve!
Top Tips For Making Vegan Alfredo Sauce
- If you don’t have a high-speed blender, you MUST soak your cashews in hot water for several hours. Otherwise your sauce will not get the right consistency!
- Reserve a little of your pasta water and add it to your alfredo a tablespoon at a time to help thin the sauce and help it cling to the noodles.
