How to make Duck Fat Mayonnaise
Mix all of the ingredients except for the duck fat in a blender until nice and smooth.
Keep the blender running on medium speed, and add the duck fat VERY slowly – like at a drip speed. It should take about 4 minutes to add all of the duck fat.
After all of the duck fat is added, blend a little longer (about 30 seconds – 1 minute) until the mixture reaches the consistency of mayo.
Gobble up and enjoy. Add it to your steaks, make my Cobb ‘Salad’ with Duck Fat Ranch Dressing, or pair it with whatever!
Store in the fridge in an air-tight container or in a condiment squeeze bottle, if you prefer.
Tips to make the best Duck Fat Mayonnaise
- When you add the duck fat to the base mixture, make sure you add it VERY slowly. I know you’re probably itching to eat this fatty goodness, but don’t rush this part!
- If storing in a condiment squeeze bottle, the mayo may firm up a bit after sitting in the fridge. Just squeeze the bottle a few times to massage it and it will end up squeezing out.

Love it! Guilt free mayonnaise. Tastes just as good if not better than traditional mayo! This is my favorite place to get recipes. I have plans to make so many of them – carnivore bread, carnivore club, honey mustard, ox tail soup, muffins. Every recipe I’ve made has been a major success on all fronts. Keep em comin!
Author
Ahhh, this is great! I’m glad that you’re enjoying the recipes. 🙂
Do you think this would work with only egg yolks? I am sensitive to the whites?
Author
Yup! Yolks only would work.
How long does it keep in the refrigerator?
Author
It will keep for a few weeks (up to about a month) in an airtight container in the fridge.
Ashley, to up the ante, would the recipe work by going the whole duck, i.e., using duck eggs instead of chicken eggs…?
Author
That would work! Many of my readers have subbed chicken eggs for duck eggs in various recipes with success.
Maybe a silly question but is the duck fat going in solid, just little blobs at a time or has it been heated and added slowly, drizzling in?
Author
I store our duck fat at room temperature. To my knowledge, duck fat should be liquid at room temperature and that’s the consistency I use to make the mayo. If yours is solid, you’ll want to heat it to get it to a liquid consistency.
Absolutely delicious. I have tried bacon fat mayo and this is much better in my opinion. Really love it. I am pulling out a loaf of carnivore bread as I type this. Thanks for all the great recipes.
Is it possible to not use lemon juice and just double the ACV?
Author
Not sure how it would taste, but yes! You could also just leave out the lemon juice and include the listed amount of ACV. No need to double unless you want to. Lemon juice was added for flavor.
I make mayo with extra virgin olive oil all of the time and have for many years. I always use the immersion blender method. I had the grand idea of using leftover duck fat from a can of duck confit some ten years ago. I tried over and over again, but never got a proper emulsion, with the mayo always breaking. Do you have any tricks about how you avoid the fat separating?
Author
Hmm, I have never used an immersion blender, so I can’t give feedback there. Have you tried a countertop blender? I’ve made this duck fat mayo plenty of times using a countertop blender and never had any issues. It always comes out thick with a consistent texture throughout, just like “regular” mayo.
My bad, I didn’t know until shortly after posting my question that duck fat at room temperature is a liquid. Sorry.
I wonder if this would work with pastured lard? That’s what I have available local to me, and the duck fat at my butcher’s shop is from several provinces over (and not organic). Have you ever tried it with other animal fat varieties? Chicken fat, pork lard, etc?
Author
I have only tried this recipe with duck fat. What is the texture of pastured lard? Is it firm like beef tallow or liquid like duck fat? If it’s similar in texture to duck fat, I don’t see why it wouldn’t work.
When you say, “add the duck fat VERY slowly – like at a drip speed”, how do you add a cup of coagulated duck fat slowly? Or, do you warm it to a liquid and then slowly pour it in?
I followed the recipe, the mixture stayed liquid ☹️
Author
Hmm. Did you use EPIC duck fat, or another brand? I assume you poured it in VERY slowly?
I love the idea that you can have foods you’re used to using but in carnivore format.
My mayonnaise struggled to get thick which may be the result of adding duck fat too quickly. To fix this I added a little unflavored gelatin. It was also very apple cider vinegar forward so I turned it into ranch. This made for a yummy addition to the pantry.
Would this work on a ninja blender or is it too big to catch all of the ingredients?
Also, have you tried this with a whisk? Manually I mean, the old fashioned way.
Author
Never tried manually. Blender will work as long as there is a hole at the top where you can pour in duck fat gradually.
I had no goose fat, so tried with melted butter omg, amazing. Then tried with goose fat and double the amount of mustard and salt, omg, to die for as makes it spicier. Then added garlic….. stunning!! Thank you for this amazing recipe x
Can this freeze ok? I’m the only one that would eat this and it may be too much for just me 🙂
Author
Hmm, never tried to freeze it. Could you make a half batch?
