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 low 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!

  • 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, 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.

    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.

    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.
