Was cheese the hardest thing to give up when you switched to a vegan diet? It was for me! I can thankfully say that I don’t crave it anymore. It took about a month to get it out of my system!

But now, I do crave THIS AMAZING BEST VEGAN CHEESE SAUCE EVER!! I hope you love it as much as I do. I seriously make a batch of it every week.

In order to make this recipe cheesy, you need nutritional yeast also known as “nooch”! This makes for a noochy-licious recipe! But, the secret ingredient is… roasted red peppers! I’m starting with the key to the whole recipe!

NOW YOU KNOW!! It gives the sauce the orange color and also brings in some great flavor. You can also add a tbsp of the brine from the jar. It adds a bit of extra zing. I do this all the time, but it’s not necessary! Also, the liquid smoke brings a slightly smoky flavor, which is optional if you don’t like this, but it brings another dimension to the sauce that I can’t do without! Colgin has different flavors. I often use hickory or mesquite.

Put all ingredients into your Vitamix blender. Blend on high for about 5 minutes, until the sauce thickens and the motor sounds like it is slowing down. You will also notice that the level of the sauce is stable. This means that it is hot and has thickened. Stop the blender as soon as you reach this step.

I love my Vitamix!

Transfer to a glass dish and refrigerate. This keeps in the fridge for a week or more.

If you don’t have a blender that heats from friction, you can still make this recipe. Blend all ingredients until smooth. Then, transfer to a pot and heat on medium, stirring frequently. Once the sauce thickens, remove from heat.

This vegan cheese recipe makes approximately 6 cups of delicious cheese sauce.

What will you eat your creamy vegan oat cheese sauce with?

  • Use this in any Italian or Mexican dish!
  • Use this for macaroni and cheese recipes
  • Pour it on a baked potato or homemade potato fries.
  • tacos, taquitos, enchiladas, tortillas, quesadillas…
  • vegan cheese dip with tacos
  • pizzas, lasagnas…
  • steamed veggies (broccoli and cheese!)
  • you get the picture…

This sauce will thicken as it cools in the fridge. When reheating leftover sauce, you may need to add a bit of plant-based milk and whisk it up. Don’t worry, it will still taste great and heat up beautifully, in the microwave on 70% power.

This is not my original recipe. It was inspired by Jill McKeever at Simply Daily Recipes. I added a few options such as white beans or cashews if you want to add more protein sources to your sauce… or hide the beans in there so your kids get that hidden nutrition!

This recipe makes approximately 6 cups of sauce. 115 Calories per 3/4 cups of sauce. Add the amount of sauce needed to your pasta or other dishes. If too thick, add warm water and blend a bit more. When making pasta, reserve a bit of pasta water when draining. You can add a few tablespoons of the pasta water to the cheese sauce when mixing into the pasta. Enjoy!
I love the Vitamix Blender. I got mine refurbished from Amazon and highly recommend it. I have had no problems with it and just love that it blends everything so smoothly and even heats up under friction. Check it out here.
