How to make vegan fettuccine Alfredo

Cook pasta

Using a medium-sized pot, cook your fettuccine according to the package directions. 

Spiralize zucchini

If you want to add spiralized zucchini to your pasta dish, create little “zoodles” and add them to the pasta water for the last 2 minutes of cooking.

Stir so that everything is covered with water. Once the pasta is al-dente, drain the pasta and zoodles.

Make Alfredo sauce

Follow our easy 15-minute recipe: steam cauliflower, onion, and garlic in vegetable broth. Once soft, add them alongside a handful of other ingredients to a blender and blend until smooth.

Adjust to taste preferences.

Tip

If your sauce is too thick, mix it with some cooking water from the pasta!

Combine & serve

Pour the Alfredo sauce over your cooked pasta in the pot and stir gently until everything is coated.

Divide your dish between serving bowls and top with fresh herbs, lemon, and vegan parmesan!

Storage & serving suggestions

This fettuccine Alfredo is best served immediately on its own, with freshly baked bread, or alongside a green salad with a vegan dressing.

Any leftovers are best stored separately in airtight containers in the fridge. The pasta and sauce should keep well for 5 days. You can freeze any extra Alfredo sauce for up to 3 months and reheat it at your convenience!

FAQs & tips

I don’t have a spiralizer

Use a mandolin or sharp knife to create thin zucchini strips instead of making zoodles. Find out more in our spiralized veggies guide!

There’s always the option to skip the added vegetables and only use cooked pasta for your vegan Alfredo.

Dietary adjustments

  • Lower carb: use more zucchini noodles instead of wheat-based pasta.
  • Gluten-free: use gluten-free pasta for this recipe.
  • Higher protein: choose legume-based pasta and add tofu to your Alfredo sauce!
  • Higher fat: sauté the veggies for your sauce in olive oil or add 1-2 tbsp almond butter to the ingredients before blending them.

Make it kid-approved

If you assume that your kid (or any other family member) wouldn’t like this dish as written in the recipe, skip the added zucchini noodles and choose their favorite pasta instead. Then add a good handful of vegan cheese shreds to the sauce!

Although this will increase the caloric content of the dish, it will be more palatable for picky eaters!

Ingredient swaps

Add a handful of fresh spinach to your cooked pasta instead of spiralizing zucchini if you want! 

Other veggies you can add to this dish are steamed broccoli, green beans, peas, cherry tomatoes, mushrooms, or bell peppers.

Make the sauce a bit richer and soy-free by preparing it with coconut milk instead of soy milk.
