I love trying all kinds of new plant milk recipes, and this oat milk alfredo did not disappoint! I tried sauces with almond milk and coconut milk, soy milk, or even cashew milk but this oat milk took the cake. Thick and creamy, this sauce is the perfect pantry staple dinner. I used a simple homemade oat milk recipe for this – but you can use any unsweetened store-bought oat milk brand you love.
Loaded with fresh garlic and parsley, this sauce is a great vegan version of this classic alfredo.  And if you can’t get enough of oat milk pasta, try my Oat Milk Mac and Cheese recipe too!  It’s creamy, dreamy, and family friendly.

What’s In This Alfredo with Oat Milk Recipe?

See the recipe card below for full ingredient amounts and recipe instructions!

  • Pasta: I used a long linguine pasta, but you can use fettuccine pasta, spaghetti, angel hair, bucatini, or any other long pasta shape!
  • Extra Virgin Olive Oil
  • Fresh Garlic Cloves
  • Corn Starch: A mixture of corn starch and cold water will thicken the sauce making this an irresistible creamy and luscious pasta dish!
  • Oat Milk: I used my easy homemade Unsweetened Oat Milk recipe, but you can use store-bought oat milk… just make sure to use unsweetened/unflavored!  If making your own, use certified GF oats.
  • Garlic Salt: for a little extra flavor and spice in this pasta.
  • Fresh Ground Pepper: I use tellicherry pepper corns because they have a nice flavor with a hint of spice, and are a great value for the quality of fresh pepper corns.
  • Fresh Parsley: to give the alfredo pasta sauce a bright fresh finish.

Optional Add-Ins

  • Cooked protein – crispy tofu, rotisserie chicken, or sauteed tempeh.
  • Nutritional yeast could give this a cheesy vegan flavor if you had any on hand – a great vegan parmesan cheese alternative.
  • Garlic Powder – for a little extra flavor in spice form.
  • Lemon Juice or Lemon Zest – for a extra hit of acidity and flavor.
  • Raw Cashews – for extra crunch

How Do I Make This Oat Milk Pasta Sauce Recipe?

  1. Cook pasta according to package instructions.  Save 1 cup of the pasta water and set aside.
  2. While pasta is cooking, in a large pot heat olive oil over medium heat. Add the garlic and sauté for 2 or 3 minutes until the garlic begins to brown. Sprinkle in the corn starch and stir until a thick paste forms.
  3. Add the oat milk, garlic salt and pepper, and stir.  Add the pasta to the sauce and top with parsley.  If sauce is too thick, add the cooked pasta water 1/4 cup at a time until the sauce is the consistency you prefer.  If the sauce is too thin, add 1 tablespoon of corn starch and turn up the heat as you whisk!
  4. Top with black pepper and fresh parsley, and enjoy hot.

  • 8 ounces pasta of choice use certified gluten free pasta if needed
  • 2 tablespoons olive oil
  • 4 garlic minced
  • 1 tablespoon corn starch
  • 1 tablespoon cold water
  • 1 cup unsweetened oat milk recipe below
  • 1 teaspoon garlic salt
  • 1/4 teaspoon Black Pepper
  • 1/4 cup fresh parsley


  • Cook pasta according to package instructions.  Drain, saving 1 cup of the pasta water and set aside.
  • While pasta is cooking, in a large pot heat olive oil over low heat. Add the garlic and saute for 2 or 3 minutes until the garlic begins to brown.
  • Add the corn starch and the cold water in a separate dish, and mix until corn starch has dissolved. Pour this mix over the garlic.
  • Add the oat milk, garlic salt and pepper, and stir until the sauce begins to thicken.
  • Add the cooked pasta to the sauce and top with parsley. 


To Make Your Own Unsweetened Oat Milk:

  1. .Combine 1 cup oats (use certified gluten free if needed), 4 cups water, and pinch of salt to a blender.  Allow the ingredients to sit for 10 minutes before blending.
  2. Blend on high for 30 seconds.  Strain immediately though a fine mesh strainer, cheese cloth, or a nut milk bag. Do NOT squeeze the oat milk, let it drain naturally. Squeezing it can cause it to become slimy.
To thicken your sauce: add 1 tablespoon of cold water to 1 teaspoon of cornstarch in a separate bowl, mix well to combine. Add corn starch mixture to the pasta sauce while it is warming and stir for a minute or two until it thickens.
If sauce is too thick, add the cooked pasta water 1/4 cup at a time until the sauce is the consistency you prefer.

Dietary Modifications

  • To make this recipe gluten free, Make sure the oats and pasta you are using are certified gluten free. While oats are naturally gluten free, there can be cross-contamination during processing, so always make sure your oats have the Certified GF stamp on the packaging if you must avoid wheat.
    • If you are using a pre-made oat milk, many are not gluten free, so always buy one that has the certified stamp on it.

    Delicious. I used full fat milk by Oatly, 4 garlic cloves, salt and pepper and corn starched. I also used gluten free elbow noodles. It was easy I love recipes that don’t require 30 ingredients. Only thing I would change is not using so much garlic, I would probably use two next time. Still good either way.

    This was quick, easy and tasted great! I had no problems thickening this up at all. I do always use Arrowroot powder so I didn’t use flour. I also added in some Nutritional yeast shortly after the milk. I did have to add a little of the pasta water to thin it a bit. And I do have to admit I am usually heavy handed where garlic is involved… 🙂 This is a keeper for me but may have to increase the amount so I have plenty to cover mushrooms, or broccoli or cauliflower along with the pasta! Thank you for the recipe!

    My girlfriend wanted a creamy pasta and I didn’t have any (vegan) cream in so I tried this instead, not expecting much as it just uses oat milk. But I was completely wrong! This was absolutely delicious and easy to make from ingredients I always have in. Also a 15 min recipe that actually only took me 15 mins!

    It looks like some people have had trouble getting the sauce to thicken. A couple of tips: I think you do need to use corn flour/starch (not just plain flour) and you might need to increase the heat a decent amount. It probably took about 10 mins for me.

    I’m a bit confused. You provided what ingredients to use, but not the measurements. How much garlic? How much black pepper? How much oat milk? How are we to create this amazing looking dish without proper measurements? I’d genuinely like to know.

    • Michelle

      I couldn’t find it either. I had to scroll through 4 times before the ingredients and instructions showed up. All the ads were super slow loading so maybe it just takes a little while for the ingredients part to pop up, too? Looking forward to trying it, tho!

    made this for myself today so that I could have dairy and GF alfredo sauce on my pasta, only made one serving. I have to say it was pretty good. I did use more cornstarch than indicated, and more minced garlic and will use even more next time, and some onion flakes. I did not have fresh parsley so I used the dried variety which I only added when I ate. I did not have any vegan parmesan so I ate it without. Next time I will add more spices (I will have to research this to find out what would give it even more flavour). Thank you

    I attempted this recipe, and I was a little discouraged at first. With just a single tablespoon of flour, I couldn’t get it to thicken to save my life. I had been cooking for 30-40 minutes, and it was still really runny. I added some more flour, and continued to cook for about 20 more minutes. Ultimately, it took about 1 and a half tablespoons of flour, a higher heat, and 50-ish minutes for it to finally get to where I needed it. I will say it was very yummy once I finally got everything in check. I’ll use this recipe again, but I’ll be sure to just add a little more flour, heat, and cooking time.
