Step 1: Get your Pasta Water on The Stove 

I can’t stress this enough: always get your pasta water started first! Multi-tasking is a key to time-efficient meal preparation. You don’t want to get everything done, and then be waiting for the water.

A watched pot never boils! While the water is heating up, move on to step 2.

Step 2: Heat your Cashews and Almond Milk 

In a microwave safe bowl or measuring cup, heat your cashews and almond milk for 3 minutes. Stop and stir, then microwave another 2 minutes.

I choose to use an almond/cashew milk for this sauce, but any alternative (i.e. soy or oat) will work.

Microwaving these together softens the cashews quickly making it easier to blend a smooth sauce. Alternatively, you could skip the microwaving process by soaking the cashews and milk in the fridge overnight to soften them. 

Step 3: Grab a timer and Cook the Pasta 

Grab your phone or kitchen timer and set it to the required time on the package to cook the pasta to an ‘al-dente’ firm texture. Place your pasta in the boiling water and start the timer.

Here is a trick we use in restaurants: pre-cooking and shocking the pasta. To save time on cooking, boil the pasta ahead of time then ‘shock’ it in ice water to stop the cooking process.

How to Shock Your Pasta

Drain it from your pot of boiling water, place it in a bowl of ice water, and then drain it again. To prevent sticking, toss it in a little bit of olive or avocado oil. The pasta can be stored up to 5 days in the fridge. Reheat it with sauce in the microwave or on the stove top.

Step 4: Blend sauce and enjoy 

In the blender place all other ingredients for the alfredo sauce, gently pour over the cashews and warmed liquid.

Secure the lid on your blender and puree until smooth, about 2-3 minutes. Once it has been blended smoothly simply toss with your pasta and dig in!
