When comfort food calls nothing quite compares to creamy vegan Alfredo. This is my go-to when pasta cravings hit fast. The sauce is velvety garlicky and made from simple ingredients that always seem to be on hand. In under thirty minutes dinner is done and everyone is satisfied.

I first made this recipe when my fridge was bare except for a carton of oat milk and some leftover parsley. Now it is my lazy Sunday secret weapon for fuss free creamy pasta.

Ingredients

  • Vegan butter: adds luscious creaminess and savory depth look for plant based options with simple ingredients
  • Fresh garlic: brings authentic flavor and warmth buy firm bulbs with no sprouting
  • Plant based milk: like oat or soy makes the sauce rich and smooth choose unsweetened and unflavored
  • All purpose flour: creates the essential thick and silky texture organic flour works best for me
  • Fettuccine: classic for Alfredo but any pasta will work go for bronze cut or whole grain if you like more bite
  • Vegan parmesan: brings the sharp cheesy note check labels for minimally processed versions or use homemade
  • Fresh parsley: adds brightness and balance flat leaf is best and fresher bunches hold flavor
  • Salt and pepper: essential for seasoning use flaky sea salt if possible and freshly cracked pepper for punch

Step-by-Step Instructions

Cook the Pasta:
Boil a large pot of salted water and drop in the fettuccine. Stir occasionally and cook to al dente so the noodles retain a satisfying bite. Drain well and set the pasta aside. Scoop out half a cup of the pasta water before draining to loosen the sauce later if needed.
Make the Garlic Butter Base:
Place a large pan over medium heat and melt the vegan butter completely. Add the minced garlic and let it cook gently for four to five minutes. Stir often to avoid burning and wait until the garlic is fragrant and lightly golden which unlocks its sweetness.
Add the Milk and Slurry:
Reduce the heat and slowly pour in your choice of plant based milk. Turn off the heat and whisk in your flour slurry until the mixture is completely smooth. Turn the heat back to medium and keep whisking gently as the sauce begins to bubble and thicken. If it is runny whisk in a touch more slurry until it coats the back of a spoon.
Season the Sauce:
Sprinkle in the garlic powder along with generous pinches of salt and pepper. Lower the heat and let the sauce simmer another five minutes. This is where the garlic and cheesy notes really mellow and combine for deep flavor.
Toss in the Pasta:
Tip the cooked fettuccine straight into the pan with sauce. Use tongs to toss the noodles until every strand is slicked with creamy goodness. Let it cook together for a couple more minutes so the flavors fully join.
Finish it Off:
Remove the pan from heat and stir in the grated vegan parmesan. Add the chopped fresh parsley last for a hit of color and brightness. Taste and adjust salt or pepper if needed.
Serve and Devour:
Serve hot right away for ultimate silky sauce. Add more pepper on top if you love a kick and dig in while it is creamy and fresh.

Vegan parmesan is my not so secret ingredient for Alfredo magic. Once my niece asked for thirds because it was the cheesiest pasta she ever had. This recipe is now a family favorite passed around our dinner table all year long.

Storage Tips

Let pasta cool and store in an airtight container in the fridge. It holds for up to three days. To reheat add a splash of plant milk and warm slowly in a pan stirring frequently. The sauce stays creamy with gentle heat.

Ingredient Substitutions

Swap in any plant based butter or margarine you love for vegan butter. If you do not have vegan parmesan try nutritional yeast for a savory cheesy edge. Gluten free pasta or chickpea pasta both work perfectly in this recipe.

Serving Suggestions

Pair with a crisp green salad for freshness. Garlic bread makes this meal shine with a little crunch. For extra green power toss in steamed broccoli or peas during the last step the sauce welcomes add ins.
