Whether you’re doing it for your health, or for the benefit of the animals, trading even one animal-product-heavy meal for a vegan one makes an impact. Cholesterol-free but still decadent, this is an easy swap to make because it doesn’t taste healthier. But it totally is!
Lactose intolerant? This is the Alfredo sauce that isn’t going to send you running to the bathroom. Points for ease because you mix it in your blender. Oh, and if you just happen to be vegan? This is the comfort-food pasta of your dreams.
But given that Alfredo sauce is almost entirely made up of animal products, how do we make it vegan? Let me show you!
PLANT-BASED DAIRY SWAPS
Parmesan cheese – nutritional yeast
It might not smell like feet, but nutritional yeast will impart the right amount of nutty, cheesy flavour to your alfredo sauce.
Heavy cream – cashew cream
Cashews are wonderfully versatile as a dairy alternative. When combined with water, salt, and lemon juice or lactice acid, it makes a delicious heavy cream. And, similarly to cow’s cream, it will thicken if you heat it. If you are nut free, or just looking to switch it up a bit nutritionally, a 2-to-1 ratio of hemp seeds to water is delightfully creamy and will also thicken when cooking.
Butter – plant butter
You could use margarine, but a plant butter like Miyokos or Nuts for Cheese imparts an additional richness. Bonus points if you make your own, but I’m not usually feeling that ambitious.
When we combine these 3 with some garlic we’re ALMOST at alfredo sauce. We still need butter and heat. So add those to a deep frying pan, and once our butter is melted, transfer the pasta and at least half the sauce, stirring well to combine. Add more sauce as needed. If at any point it seizes up or gets too thick, toss in a tablespoon or two of the pasta cooking water. The added water will make it nice and silky again. Stir in or top with your add ons, and serve! Ta dah!
But wait – this recipe also works really well for meal prep. Let me tell you how!
MOVE OVER, MICHELLINAS!
Once you’ve blended your sauce nice and smooth, portion it into silicone cups and freeze overnight. Divide your cooked pasta among 4 freezer-friendly containers. Add a puck or two of sauce into each container; make sure it’s airtight and freezer safe. Keep in the freezer up to 12 weeks. When you’re ready to eat one, microwave from frozen on high for two minutes, covered. Remove cover, stir, and continue to microwave in 45 second increments until it reaches your desired temperature.
