A recipe for bacon mayonnaise is one food everyone on the keto diet should learn how to make. Also called baconnaise, this spread is easy to make and full of bacon flavor.
Low Carb Bacon Mayonnaise Recipe
Instead of using traditional mayonnaise for your low-carb sandwiches, wraps and dressing base, consider using bacon mayo. Bacon mayonnaise is creamy like regular mayo but it is bacon flavored.
Also called baconnaise, this is a keto condiment to make as long as you have saved up your leftover bacon grease from all bacon you fry every morning on your low-carb diet. What is bacon mayo made of?
Bacon mayo is primarily made out of bacon grease and egg yolk. The egg yolk helps to form an emulsion. Vinegar or an acid like lemon juice is added to the egg yolk to help keep that emulsion together. Bacon grease is very slowly drizzled into the egg yolk while mixing constantly. If the bacon grease is added too quickly the emulsion can break and you will get an oily liquid instead of mayonnaise.
After all the bacon grease is added to the egg yolk and it has a mayo like consistency, you can add other ingredients to enhance the flavor of the bacon mayonnaise.
In this recipe, we add Dijon mustard. Consider adding any of the following to help liven up the flavor of your bacon mayo:
- cayenne pepper
- red pepper flakes
- sriracha sauce
- hot sauce
- liquid smoke
- minced red onion
- minced garlic
- bacon bits
- chives

This bacon mayo turned out delicious. I used lemon juice instead of vinegar and it still emulsified perfectly. Just be sure to drizzle the grease super slowly like the recipe says.
I followed the recipe exactly and was really impressed by how emulsifying the bacon grease slowly created such a creamy and smooth texture. Using room temperature yolks made the blending process so easy and seamless in the food processor. The dijon mustard added a subtle tang that balanced out the richness of the bacon perfectly. I also liked the hint of acidity from the apple cider vinegar, which cut through the fat just enough without making it too sharp. This mayo was incredibly thick and held its shape really well, which made it perfect as a spread for lettuce-wrapped burgers.
Has anyone tried using the wisk attachment on a kitchen aid mixer to make this?
Good idea!
So delicious! I used my immersion blender at the second speed, there’s only two. It worked so wonderfully. Thank you for sharing this recipe. ☺️
So I've tried this twice, failed twice. I used the food processor, drizzled slowly the liquid (Luke warm not hot) bacon grease and I could never get it to combine properly. I'd love some thoughts.
I tried making this and had two failures. First time round I used an emersion blender and the second time I used a food processor. Both times it became soupy, never getting thick like a mayo. Any advice? I was so bummed when it didn't work.
It sounds like you emulsion keeps breaking. You have to all the oil slowly to the egg yolk while mixing.
What is the serving size?
2 tablespoons
My emulsion broke using 1 cup of bacon grease. I think 1/2 or 3/4 cup would have been better.
Oh my! I am thankful you posted this recipe! I love it! Turned out exactly as Mayo should be. Last commenter used half bacon grease and half butter.. I think I will try that next.
Recipe was perfection!!! ? Thanks for sharing!! I used 1/2 melted butter & 1/2 bacon fat for more of a hollandaise sauce mayo. Was utterly delish! My kiddo loved it. (We also added an extra teas of lemon + vinegar, because we like it on the tangier side) Just what we're used to. ;)
I only had 1/2 cup of bacon grease so I used avocado oil for the other half. This worked perfectly with my immersion blender. The avo baconnaise is delicous!
I made this exactly as written and it came out with a very nice consistency, but then solidified once I put it in the fridge. Any ideas?
It didn’t work using an immersion blender, to liquidy. Will try again.
Sometimes you have to have the perfect speed to keep the emulsion from breaking. Try adding another yolk if that happens.
What do you use this for? It melts on anything warm. I did mix some tuna to make tuna salad but what other ideas are out there?
I use it on chaffle sandwiches.
Deviled eggs or chicken salad? anywhere you'd use regular mayo I suppose.
Devilled eggs!!
Chicken salad
Egg salad
Won’t the “Mayo” break after the bacon fat becomes solids again?
Nope, it stays in this emulsified state
How do you store this?
It will keep in the refrigerator in a tightly sealed container for up to a month.
