Homemade Bacon-Flavored Mayonnaise – BACONNAISE!

by Texas Homesteader ~ 

RancherMan likes to eat tuna sandwiches. He usually takes the quick route by just opening the tuna can, draining it and placing the meat on a mayonnaise-covered piece of bread.  LOL.

And when I’m making egg salad sandwich spread I use mayonnaise for that as well.

But I don’t typically buy mayonnaise. I’ve written before about making Garlic-Flavored Mayonnaise and I do still make that flavor from time to time. But I began experimenting with various flavors, oils & fats when making my mayonnaise.

But recently when I was making a batch of mayonnaise I wondered… Hummmm…

I can make my own bacon-flavored mayonnaise in minutes. #TexasHomesteader

Although we don’t eat bacon often, I have a couple of families saving their bacon grease for me. It’s a necessary ingredient in my Buttermilk Biscuits and homemade Sandwich Bread too. So I very much appreciate their saving this bacon byproduct for me.

When I make homemade mayonnaise I typically use 1/2 cup of oil.  But I wondered, what if I added a tablespoon or so of bacon grease?

Oh man, I’ve gotta try that, who doesn’t love the flavor of bacon??!!

And Bacon-Flavored Mayonnaise? BACONNAISE! Yeah, I’m *so* gonna do that.

My Baconnaise Ingredients

So I brought out the few simple ingredients necessary for my bacon-flavored mayo: one of our hen’s large eggs, lemon juice, bacon grease, oil, salt and mustard powder. I prefer canola oil, but I’ve made it with olive oil or vegetable oil in the past as well. 

UPDATE: I now prefer to just squirt about a teaspoon of prepared mustard instead of using mustard powder. It turns out just as tasty and there’s no measuring needed. LOL

Bacon-flavored mayonnaise ingredients. Bacon greas, oil, egg, dry mustard and lemon juice. I've made our mayonnaise homemade for a long time but recently got to thinking... BACON! Now I almost always make Baconnaise! #TexasHomesteader

I cracked the egg into a wide-mouth repurposed jar and added the other ingredients. Then I gave ’em a light mix together and let the mixture sit out on the counter for about 10 minutes to attain room temperature. I dunno, I’ve read that’s a necessary step so I always do it.

Using A Stick Blender For Fast Results

Now that everything’s room temp, here’s the difficult part. I pulled out my stick blender and pushed the blade all the way to the bottom of the jar. I turned it on but left the blender at the bottom of the jar without moving it. The magic started to happen pretty immediately.

I left the stick blender operating from the bottom of the jar for about 20-30 seconds. Then I gently rocked the blender to make sure everything was getting incorporated. More & more it was looking like mayonnaise!

When things started to thicken up I slowly raised the stick blender toward the top of my mayonnaise to get everything incorporated.

Finally I lowered & raised the stick blender throughout the mayo a few times just for good measure. It was now thick like mayonnaise. success!!

Now remember, you’re using bacon grease. As such, there are two things to consider.

  1. Bacon grease gets more solid when it gets cold. So even if your mayonnaise is somewhat thinner than you like, it’ll thicken right on up once it’s cold!
  2. Since bacon grease tends to be salty, use caution when adding any additional salt. it’s easy to go overboard here.

But yeah, making homemade baconnaise really is just that easy!

Finally I stirred in a little whey my my homemade yogurt. It’s said that adding whey helps the mayonnaise last longer in the fridge.

We typically go through our mayo pretty quickly anyway so I don’t always add it. If you’re planning on storing it in the fridge for longer than a week or two it might be good to add a smidge of whey.

A quick label by writing directly on the jar & then my baconnaise is stored in the fridge.

So BOOM!  Baconnaise! It’s a nice twist with RancherMan’s tuna sandwiches and it’s delicious in our Egg Salad Spread too.

But I really, REALLY love to make my homemade Thousand Island Dressing with it.

Bacon-flavored mayonnaise goes great in my homemade thousand island salad dressing. #TexasHomesteader

Although I’m typically an Italian Dressing or Healthy Yogurt-Based Salad Dressing kinda girl, my lips smack for that Thousand Island dressing when it’s made with Baconnaise!

Homemade Bacon-Flavored Mayo - BACONNAISE!

I've made our mayonnaise for a long time but recently got to thinking...  BACON!  Now I almost always make Baconnaise instead by adding a touch of bacon grease along with the oil. #TexasHomesteader

Cuisine American
Keyword bacon, Mayonnaise
Prep Time 5 minutes
Author www.TexasHomesteader.com


  • 1 Extra-Large Egg (at room temperature)
  • 1 teaspoon Lemon Juice (at room temperature)
  • 1 teaspoon Prepared Mustard (at room temperature)
  • 1 Tablespoon Softened or Melted Bacon Grease
  • ½ Cup Mild oil such as Extra Virgin Olive Oil or Canola Oil
  • Salt to taste (note, bacon grease is often salty enough)


  1. Crack the egg into a wide-mouth canning jar and add the remaining ingredients. Blend together and let the mixture sit until it gets close to room temperature – about 5-10 minutes.

  2. When all is room temperature, with an immersion blender at the bottom of the jar start blending, leaving blender head on the bottom of the jar until ingredients are fully blended & thickened.

    Then gradually raise the blender toward the top of the mixture to make sure all is blended and your mayonnaise is thick.

    (Note: the bacon grease will thicken your mayo a little more when it gets cold)

  3. Store in the refrigerator for a week or so.

Recipe Notes

NOTE: if using melted coconut oil in your oil mixture, only use a couple of tablespoons since it will harden in the refrigerator and make your mayonnaise too thick.

We go through our mayo pretty quickly so I don’t really know how long it will keep, I’ve read that it will keep several weeks but I’ve never had it long enough to test that. Let me know how long your Baconnaise lasts!

    This is delicious. I’ve made homemade mayo before but the addition of a little bacon flavor is amazing. And the consistency tends to be a little thicker when it’s chilled with the addition of bacon grease too. BACONnaise for me from now on!

    Just need some grassfed bacon.
    Thanks for sharing.

      We went through lots of mayo too DavetteB, that’s why I wanted to learn to make it in the first place. But BACONnaise?? Oh yeah!

    Oh my goodness………. yes. Yes to Baconnaise.
    In January we butchered a couple of pigs & (for the first time) brined our own bacon & then had it smoked. The stuff is gold to us – never had better, honest. I never used to cook in bacon grease from store bought bacon because I didn’t think it added much flavour. Now, I’m a total convert. I run every batch of grease through a coffee filter & use it in SO many dishes for a strong hint of bacon flavour; I even started making a COOKIE recipe with bacon fat!
