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.

Although we can’t afford to 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. But recently when I was making a batch of mayonnaise I wondered… Hummmm…

I've made our mayonnaise homemade for a long time but recently got to thinking... BACON! Now I almost always make Baconnaise! #TexasHomesteader


When I make homemade mayonnaise I typically use 1/2 olive oil and 1/2 another kind of oil.  But I wondered, what if I used 1/2 olive oil (or melted coconut oil) and 1/2 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.

So I brought out the few simple ingredients necessary for my mayo: one of our hen’s large eggs, lemon juice, bacon grease, olive oil, salt and mustard powder. I cracked the egg into a wide-mouth repurposed jar and added the lemon juice. 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. I also measured out my bacon grease & sat it on the counter as well for it to warm up a bit.

After 10 minutes I added the salt, dry mustard, and bacon grease to the jar. I pulled out my stick blender and got everything blended smooth. Then I measured out my olive oil and poured it verrrrry sloooooowly to emulsify the whole shebangie into mayo. Yeah, making mayonnaise 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 but I always include this step just in case.

Now since the texture of bacon grease is more solid when it’s cold, I don’t worry too much this time about running the stick blender until everything gets ‘mayonnaise thick’. I know a stint in the fridge will thicken it up nicely anyway. I just blend it until it’s thick-ish and call it good. 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. Although I’m typically an Italian 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!

Author www.TexasHomesteader.com


  • 1 Egg (at room temperature)
  • 1 teaspoon Lemon Juice (at room temperature)
  • 1/8 teaspoon Salt
  • ¼ t Mustard Powder
  • ¼ Cup Softened Bacon Grease
  • ¼ Cup Extra Virgin Olive Oil (or maybe melted coconut oil instead?)
  • 2 Tablespoons Whey from Yogurt


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

  2. Add the salt, mustard powder & softened bacon grease to the jar. With an immersion blender at the bottom of the jar start blending, until ingredients are fully blended.

  3. Then in a VERY THIN STREAM and very slowly pour in the olive oil. The ingredients will emulsify about halfway through but keep pouring slowly until all oil is incorporated. This should take about 3-4 minutes total. Finally add in the whey and blend together. Store in the refrigerator.

Recipe Notes

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!

    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!

    This sounds heavenly.
    Will be making this for sure. Will bring a whole new flavor to deviled eggs I bet; sprinkled with tiny bacon bits
