Holy Grail Creamy Vegan Cheese Sauce gets made a lot. Usually, I make one batch and freeze half of it.
When I first went vegan, I experimented with many mac and cheese “cheese” sauce recipes. Results were mixed, but nothing had really blown my mind. I was on a quest. I continued to experiment. Eventually, I combined the spices of my favorite vegan cheese ball recipe with the base of my favorite vegan Alfredo sauce recipe.
After much tweaking, there was a lot of, “Oh mah godddd, that’s good!” as we repeatedly ate spoonfuls directly out of the blender. It was a red-letter day in my two-person household. We haven’t been the same since. It was positively life-changing. At long last, Holy Grail Creamy Vegan Cheese Sauce.
We use Holy Grail Creamy Vegan Cheese Sauce to make:
- burritos
- mac & cheese
- nachos
- queso dip by adding pico or salsa
- in a power bowl with kale, veggies, and quinoa
This recipe uses sautéd onions and cashews as a base.
I use a food scale to weigh the onions after chopping and slicing because onions vary in size.
Let’s make Holy Grail Creamy Vegan Cheese Sauce
First, chop and slice up your onions, they don’t have to look pretty just try to keep them around or under ¼ inch thick. Also, if you haven’t soaked your cashews, put them in a pot with enough water to cover them, bring them to a boil and then turn the heat off and let them sit in the hot water while you sauté your onions and load the blender.
Next, put the tablespoon of Earth Balance in big sauté pan and get it to sizzle. Then at medium to medium-high heat, sauté the onions.
While you sauté your onions you can then start adding ingredients to the blender, but keep an eye on the onions and keep them moving, you want to get them to brown a little. In the blender put 1 & 1/2 cup of the broth, lemon juice, salt, black pepper, nutritional yeast, apple cider vinegar, mellow white miso, tomato paste, onion powder, mustard powder, cumin, turmeric powder, cayenne pepper.
Once onions are browning, add garlic to the pan. Sauté the garlic. Once the garlic looks amber in color, pour 1 cup of broth into the pan and turn the heat up a little. Let the onions get soft and soak up most of the broth.
This is what the onions and garlic look like, you want them to brown to add some depth of flavor.

Drain the cashews with a strainer and add the cashews to the blender. Let the onion-garlic mixture cool slightly and transfer it to the blender.
Blend until creamy. Add broth if you think the sauce is too thick. If you will be adding salsa to make this a queso, leave it thick and adjust after adding salsa. Taste and adjust seasonings, if desired (see notes below). Serve, store or freeze (see notes below). Enjoy!



It freezes well
To Freeze: Before closing the container, I put a layer of plastic wrap over the top to keep it airtight. At first, when thawing, it may appear gritty. Also, it may look as though it has separated after it has been frozen and defrosted. Just heat and stir and it will go back to being creamy and luxurious.


If it thickens in the fridge, just add broth
When storing this amazing creamy goodness in the fridge, it may thicken. To thin it back out, just stir in some low sodium no-chicken broth. You’ll have some broth left over if you make the sauce from a new container.

Equipment
- high speed blender
- large non-stick pan
- cutting board
- knife
- food scale (recommended)
Ingredients
- 450 grams yellow onion about 2 medium onions, sliced fairly thin or chopped, it doesn't have to be pretty it's going into the blender
- 1 tbsp Earth Balance or oil of choice, or omit and cook onions in a little broth in a non-stick pan
- 2 – 3 cups low sodium no-chicken broth I use imagine, you may need more to thin the sauce, depending on your preference

- 3 – 5 tbsp minced garlic (about 8 – 10 cloves of garlic) I sometimes use minced garlic from a jar
- 1 cup "raw" cashews un-roasted, unsalted, soaked overnight or boiled while you make the onions, then drained. Be sure to measure your cashews before soaking or boiling. If using whole cashews make it a heaping cup, if using cashew pieces right about a cup is good.

Did you make this recipe? What’d you eat it with or on? Tell me about it in the comments below.
This sounds like the most promising recipe for “cheese” sauce I have run a crossed. And I have tried them all. Can’t wait to try it. Thanks fore sharing your recipe. What do you think about adding some tapioca flour to give it that stretchy consistency? How much would you suggest?
Hi Cheryl! Thank you much for your kind comment. I haven’t tried doing this cheese sauce with tapioca starch, but I think it’s a great idea. I have used tapioca starch when playing around with vegan mozzarella recipes and it made stretchy cheese. I am not sure how much I would try, maybe just use a similar quantity from another recipe and start with a small amount because a little can go a long way. Please let me know how it goes, if you try it out.
