Butter Mayonnaise

Butter Mayonnaise - Buttered Side Up
I love homemade mayonnaise.

You can so easily customize it to your preferences. It's kind of like magic watching it thicken as you pour liquid fat into an egg. And it's awesome to know that you can always whip up a batch if you run out of your favorite brand of store-bought mayonnaise.

Butter mayonnaise is fantastic because: butter. It makes a pretty thick mayo, and it's smooth and, well, buttery. It's so so good on Mayo Salmon (recipe coming soonish), in tuna salad, or homemade ranch dressing.

Butter Mayonnaise - Buttered Side Up
The one downside to butter mayonnaise is that it gets hard in the refrigerator. However, you can put your jar in some warm water to get it soft quickly.

You can use a whisk (I don't advocate this unless you like whisking for a LONG time), a blender, or a stick blender to make this recipe. Just be careful about splatters as you pour in your butter!

As always, it's recommended that pregnant/nursing women, children, and those with compromised immune systems use caution when consuming raw eggs. I think it's important to use high-quality eggs if you choose to consume them raw.

Oh, and if you prefer a mayonnaise that stays soft in the fridge, check out my avocado oil mayonnaise on The Pioneer Woman's blog. I refer to that post often to use my own recipe.

Here's a video tutorial in case you learn better that way!

    1. @NYC Ann, If you made mayonnaise with melted butter instead of oil, you’d end up with something quite similar to hollandaise sauce. The key differences would still depend on the preparation:

      Hollandaise is cooked: It’s gently heated during preparation to thicken and stabilize the emulsion.

      Butter-based mayonnaise (cold preparation): If you made it cold, without heating, it might not have the same richness or velvety texture as hollandaise.

      In short, butter mayonnaise would be a cold, butter-based emulsion, while hollandaise gains its distinct flavor and texture from the warm emulsification process. They’re cousins, but not twins!

    2. @Paul, Butter based is smooth and creamy. steps above your regular storebought oil mayos.
      It will, while in fridge get firmer, but that is also solvable and remains creamy

  1. I make this all the time since discovering it - it's soooo good. Like having hollandaise sauce on tap! 😉 We avoid vegetable oils in our house as much as possible, and I really dislike the taste of olive oil mayonnaise, so this has been a lifesaver! 🙂 Thank you!

  2. So glad you like the recipe! 🙂 Yeah, I'm not a fan of olive oil mayo unless that's specifically the flavor you're going for. If that makes sense. Haha!

  3. I haven't done a lot of research on pasteurized eggs, but I haven't seen any local/cage free/pastured eggs that are pasteurized.

    1. @Erica Lea, you can pasteurize eggs yourself if you have a sous vide rig. Serious Eats says 130° F for a few hours.

  7. Can I use mustard powder and if so, how much? I cannot have any vinegar and prepared mustard has vinegar. I can't wait to try this. Thank you!

    1. I haven't personally tried it with mustard powder, but I'm sure it would work! Perhaps you could use extra lemon juice for acidity?
