Healthy Probiotic Mayonnaise

You can make healthy probiotic mayonnaise in five minutes flat!

Mayonnaise is a staple in our house. We use it on a ton of different foods.

It can be a sauce for veggies, a dressing, a marinade, or a binder for chopped meat or veggie salads… and the list goes on.

Choose the Right Oil for Your Mayonnaise.

I’m not a big fan of commercial mayo and its polyunsaturated oil and hydrogenated fats.

While olive oil is great for French aioli I find it to be too heavy for a traditional American mayo. I like to use avocado oil for my homemade mayonnaise. Avocado oil is a very healthy oil full of monounsaturated fat.

I’m still trying to figure out how I can make mayo with butter, but until then…

Lacto-Fermented Whey Adds Probiotics and Helps to Preserve It.

I use the lacto-fermented whey from my raw cow’s milk yogurt in this recipe. The whey starts fermentation — adding live bacteria probiotics and preservative acids. 

All you need to do is strain some fresh yogurt to get the probiotic-rich golden whey.

  1. Add the egg yolk, mustard, whey, lemon juice, and salt to your blender cup.
  2. I use a KitchenAid handheld blender that comes with a special cup for blending. It's awesome for sauces and dressings!
  3. Blend on low speed until the mixture is light and frothy. Slowly drizzle the avocado oil into the blender while it's running. As the mayonnaise gets thicker you can move the stick blender back and forth and up and down to make sure the oil is distributed evenly. When all the oil has been incorporated you should have a thick creamy mayo that is ready for eating.
  4. Store the mayo in a jar with a tight-fitting lid in the fridge.

Hollandaise is basically a mayo made with butter, just a thinner consistency. Made me realize why I likes hollandaise so much! :)

Nourishing traditions has whey in the mayo recipe. I’ve been putting whey in mine for years(ever since I’ve had NT) and yes you should keep it out of the fridge to ferment for a few hours. I’ve had it last a lot longer than two weeks without deteriorating at all. Although it usually gets eaten sooner.

Does it, Lucy?

I guess I've never needed to even look at Sally's recipe, I've been making this one for so long. It most likely originated with her in that case! She's a brilliant woman!

Thanks for the comment,

Hi Jo,

Yes, you could use any liquid oil, but I have to be honest and I hope you don't take offense, I would not personally recommended and seed or grain oils and they are highly processed. The best oils are the traditional animal fats, olive oil, coconut oil, and avocado oil. I would urge you to get a cold pressed avocado oil for this recipe, or do 1/2 ave 1/2 olive.

To your health,

If you can’t get raw milk, you can make the mayo with the same amount of kefir water or milk. I works just as good

Hi Sarah! Thanks for the feedback!

Hi there, do you not need to leave it at room temp for several hrs before refrigerating? Other recipes say you must do this to activate the whey so that it lasts longer. How long does your keep in fridge?. Also, can you use whey powder for this?

Hi Angela! I usually leave it out only as long as it takes to make it and eat some ;). I don't think it will really make that big a difference in the probiotic count or keeping ability. The whey I use is from raw milk yogurt so it's already really active. I would say a pint of this mayo will keep at least 2 weeks in my fridge. After that it may start to separate a little but I've never had one go bad, EVER! Whey powder will probably change the texture quite a bit, I wouldn't recommend it. Powdered whey is also not a probiotic on its own. Clabber, yogurt or kefir whey will all work well in this recipe and all will still have the beneficial probiotics intact. Or you can leave the whey out completely and substitute with a bit of water. Hope this helps! Courtney
