I'm calling this entree recipe a showstopper because it's just that good. My Ridiculously Creamy Vegan Fettuccine Alfredo has a velvety, dairy-free Alfredo sauce drenched over top tender fettuccine pasta.
The flavor is cheesy with a hint of lemon and garlic -- yet ironically has zero cheese or even nutritional yeast! And this recipe can be made in about thirty minutes, no prep needed! Get the recipe...
It's all about this sauce..

And then the pasta goes for a swim...

Any Pasta Works
And yes, you can use any variety of pasta if you do not have fettuccine. Vegan Fettuccine Alfredo can easily be made with spaghetti, penne or whatever pasta you have on hand. You could even use the sauce to coat veggies like broccoli or even zoodles.

A sprinkling of chopped herbs (or anything green to brighten the plate) and serve!..
Pair this Vegan Fettuccine Alfredo entree with some roasted veggies, a side salad or your favorite vegan protein and you have a meal worth craving.
Vegan Fettuccine Alfredo is:
- Fast! - Easy to whip this up in about thirty minutes.
- Plant-Based - Made using simple plant-based ingredients.
- Cozy + Lovable - Cravable. Comfort food.
- Veggie Optional - Easy to liven up with veggies! Fold in peas, garlicky kale, broccoli or chopped asparagus. Here is one example of mine.
- Perfectly Sauced - This sauce is epically velvety and airy. Must have: high speed blender or food processor to really whip those cashews and fluff the sauce.
Cashew-Based Sauce
My Vegan Fettuccine Alfredo uses a cashew-based sauce.
Raw cashews give creaminess. And big bonus.. you do not need to soak them prior to starting this recipe. Really.
Do a Roux - it's easy...
Roux. This Vegan Fettuccine Alfredo is made extra delicious by starting with a roux.
I used a roux to thicken the sauce to a velvety state. A roux may sound like a fancy technique, but it took me about two minutes to melt the vegan butter and whisk in the flour. Then I simply added the cashew blend, whisked again and done.
Creamy Vegan Fettuccine Alfredo
Ingredients
- 1 cup raw cashews
- 1 ½-2 cups pasta water, or hot water -- see notes
- 2 tablespoon lemon juice, fresh
- 1 ½ tablespoon white miso paste
- ⅛ teaspoon black pepper
- 1 garlic clove, optional
- ¼ teaspoon salt
- 2 tablespoon vegan butter
- 2 tablespoon flour, all purpose
- 6 oz fettuccine pasta
- garnish: chopped basil or parsley, optional
Instructions
- Bring a large pot of water to a boil and add the fettuccine pasta. Stir your fettuccine to break any pieces apart. Tip: Adding a teaspoon of oil can help prevent your fettuccine from sticking. Cook until tender.
- As your pasta cooks, start your sauce. Add to a high speed blender: cashews, miso, lemon, pepper, salt and the HOT water. Also add the optional garlic clove. For the water, you can use purified water that you boil, very very hot tap water – or scoop out some of the hot, starchy pasta water from your pot as the fettuccine cooks.
- Blend everything from low to high. Keep the blender at the highest speed for about two minutes to really create a silky sauce base.
- In a medium sauce pan, add the vegan butter over medium heat. Using a whisk, stir and melt the butter. When the butter is just about melted, reduce the heat to low and add in the flour. Briskly whisk to create a roux base. Turn off the heat when your roux forms – you do not want to burn it.
- Pour your blended cashew mixture into the roux base and briskly whisk everything together. Turn the heat back to low for a minute or two to allow the sauce to thicken just a bit. When your sauce is nice and whisked and creamy. Turn off the heat and set aside.
- Your pasta should be done by now, so if you haven’t already, drain the water. Using tongs, transfer the cooked pasta to the sauce pot and toss gently until the pasta is coated in sauce. Note: You could also do the sauce-tossing in a separate large mixing bowl if you want to control the sauce amount a bit more precisely.
- Transfer the tossed pasta to serving bowls, top with a pinch of chopped basil or parsley and serve!
