Place egg yolk, lemon juice, water and mustard in a narrow, tall container. I used a Weck jar. Pour over olive oil, then let the contents settle for a moment.
Using an immersion blender, process until the mayo starts to form. Once you start seeing mayo, gently move the blender up and down. Continue until all oil is emulsified. The texture will be thick.
Season to taste with kosher salt and store in the refrigerator for up to several weeks.

S on 2026-04-22 (1 stars): Unclear instructions left me with a liquid mayo that never thickened. Read comments and there’s specific instructions to make it work. Why not include that in the recipe?
Celia on 2026-02-12 (1 stars): This recipe did not work for me at all. I followed the instructions perfectly and it came out way too watery. I tried adding 1 egg and 3/4 cup of oil and it immediately turned into the perfect consistency.
Elena A on 2025-10-25 (3 stars): This did not at all work out for me. I wonder if it’s because I used EVOO? It’s all I had and didn’t think it would completely ruin the recipe. Or maybe I mixed it for too long? It just remained completely watery and tasted like olive oil. 😭
Mom on 2025-09-14 (1 stars): This recipe did not work.
Amy on 2025-08-21 (5 stars): My first time making mayo, how easy. Great recipe to follow, worked a treat, really quick.
Shellie on 2025-04-03 (5 stars): So easy!! I have been paying big bucks for someone else's homemade olive oil mayonnaise, no longer!
Ginnyg on 2025-02-21 (1 stars): A runny mess as per directions. I was about to toss it out, but I decided to throw in the egg white and it kind of worked. I would try a different recipe.
Brian Johnson on 2024-12-24 (5 stars): Years late reply, but it's a temperature issue. All ingredients should be the same temperature. Usually the issue being the eggs or mustard not being left out to room temp.
Ron on 2024-11-12 (4 stars): Keeping the blender at the bottom in the beginning is key to success, Thank you!
Mike on 2024-03-12 (5 stars): Easiest mayo ever, thank you. It turned to mayo with one squeeze the emulsion blender, wow!
