You're probably here because you tired of the soybean oil junk in the grocery store aisles. I get it. Most "mayonnaise" on the shelf is basically just a jar of highly processed seed oils with a tiny bit of egg for marketing. But when you try a homemade mayo recipe with olive oil, things often go sideways. One minute you're whisking away, dreaming of a creamy aioli, and the next, you have a broken, greasy mess or—even worse—a spread that tastes like straight-up battery acid.
It’s frustrating.
Making mayo is basically a chemistry experiment you can eat. You are forcing two things that hate each other—water and oil—to become best friends. If you don't respect the science, the olive oil will fight back. Specifically, the polyphenols in extra virgin olive oil are "locked" inside fatty acid micelles. When you hit them with a high-speed blender blade, you tear those molecules apart. You're literally releasing bitterness that was meant to stay hidden.
The Science of the Emulsion
Let's talk about the yolk. People think the oil is the star, but the egg yolk is the glue. It contains lecithin. Lecithin is an emulsifier, which basically means it has one end that loves water and one end that loves fat. To make this work, you have to suspend millions of tiny oil droplets within the water base of the egg and lemon juice.
If you pour the oil too fast? Game over. The droplets merge. You get "broken" mayo.
If you use a room-temperature egg, the lecithin is more flexible. It bonds easier. Cold eggs from the fridge are stubborn. If you're in a rush, just put the egg in a bowl of warm water for three minutes. It makes a massive difference in how stable the final product feels on a spoon.

Choosing the Right Olive Oil
This is where most people mess up their first homemade mayo recipe with olive oil. They reach for the "First Cold Press Extra Virgin Olive Oil" because it's expensive and healthy. Don't do that. Stop.
Extra virgin olive oil (EVOO) is too intense for a 100% olive oil mayo. It’s spicy, peppery, and, as we mentioned, it gets bitter when blended. For a successful batch, you want "Light-Tasting" olive oil. This isn't "diet" oil; it's just oil that has been refined to remove the heavy particulates and strong flavors. It has a higher smoke point and a neutral profile that actually lets the lemon and salt shine through.
If you absolutely insist on using the fancy EVOO, try a 50/50 split. Mix it with avocado oil or a neutral refined tea seed oil. You get the health benefits without the "mouth-puckering" punch of a pure EVOO emulsion.
The "Everything" Method: Using an Immersion Blender
Forget the whisk. Unless you want a forearm workout that leaves you shaking for an hour, use a stick blender (immersion blender). It is the gold standard for home cooks. You need a jar that is just slightly wider than the head of the blender. This is non-negotiable. If the jar is too wide, the oil floats on top and never gets sucked into the vortex.
The Ingredients:

- 1 large egg (must be room temperature)
- 1 cup light-tasting olive oil
- 1 tablespoon lemon juice or apple cider vinegar
- 1/2 teaspoon Dijon mustard (this acts as a secondary emulsifier)
- A heavy pinch of sea salt
Put the egg in the jar first. Then the lemon juice, mustard, and salt. Pour the oil on top. Let it settle for a minute. You’ll see the egg sitting at the very bottom, trapped under a golden sea of oil.
Put the immersion blender all the way to the bottom, pinning the egg. Turn it on high. Do not move it. You will see white clouds of mayo start to explode upward from the bottom. Keep it pinned. Once about 80% of the jar has turned white and thick, slowly—and I mean slowly—tilt and lift the blender to incorporate the last bit of oil on top. It takes maybe 45 seconds total.
Troubleshooting Your Homemade Mayo Recipe With Olive Oil
Sometimes it fails. Even the pros mess up. If your mayo looks like watery soup, don't throw it away. That's a waste of good ingredients.
To fix a broken mayo, grab a clean jar and a fresh egg yolk. Put the yolk in the new jar with a teaspoon of water. Start your blender and very, very slowly—drip by drip—pour the broken mayo into the new yolk. You’re essentially restarting the emulsion process using the failed mixture as your "oil." It works every time.
Also, let's talk about salt. Salt isn't just for flavor. It helps denature the proteins in the egg yolk, which actually makes the emulsion stronger. If your mayo feels "soft" or runny, a tiny bit more salt and a splash more acid (lemon juice) can often tighten the structure.

Why Does My Mayo Taste Like Paper?
If it tastes bland, you’re missing acid. Mayo needs a "bright" finish. Most commercial brands use distilled white vinegar because it's cheap and shelf-stable. At home, you have the luxury of using fresh lemon juice or even a high-quality white wine vinegar.
If you want that "Hampton’s" style flavor, add a tiny bit of white pepper. It gives a subtle heat that you can't quite place but makes the mayo taste "expensive."
Storage and Safety
Since you are using raw egg, you need to be smart. This isn't a shelf-stable product. It lives in the fridge.
- Shelf Life: It lasts about 5 to 7 days.
- The Fermentation Trick: Some traditional food enthusiasts (like those following Nourishing Traditions by Sally Fallon) suggest letting the mayo sit at room temperature for 7 hours before refrigerating. The theory is that the enzymes in the lemon juice and the mustard act on the egg to create a mild fermentation that actually preserves it longer. Personally? I just put it straight in the fridge.
- Risk: If you are worried about Salmonella, use pasteurized eggs. You can buy them in the carton, or you can pasteurize them yourself at home using a sous-vide circulator at 135°F (57°C) for 75 minutes.
Beyond the Basic Spread
Once you master the homemade mayo recipe with olive oil, you'll realize it's just a base. It's a "mother sauce."
Add smashed garlic and you have a cheat-code Aioli. Fold in some chipotle in adobo and lime for a fish taco sauce. Or, my personal favorite, stir in some fresh dill, capers, and chopped pickles for a tartar sauce that actually tastes like food instead of plastic.
The texture of homemade mayo is also different. It's heavier. It feels more like a custard than a whipped topping. When you put this on a warm toasted sourdough sandwich, it starts to melt into the bread in a way that store-bought stuff just can't. It’s richer because of the olive oil fats, which are mostly monounsaturated, making it a much more heart-healthy option than the "Heart Healthy" labeled soybean oils at the market.
Actionable Steps for Your First Batch
- Check your oil: Ensure you are using "Light" or "Extra Light" olive oil, not "Extra Virgin," to avoid a bitter aftertaste.
- Temperature check: Take one egg out of the fridge at least 30 minutes before you start.
- The Jar trick: Find a wide-mouth Mason jar that just barely fits the head of your immersion blender.
- The Bottom-Up Rule: Keep the blender blades on the bottom of the jar until the white emulsion is thick and stable.
- Acid Adjustment: Taste it immediately. If it feels too heavy or fatty on the tongue, add another 1/2 teaspoon of lemon juice and pulse one more time.
Stop buying the jars with 15 ingredients you can't pronounce. Once you realize you can make a better version in under a minute, there's no going back. Focus on the light-tasting oil, keep the blender still, and use a room-temperature egg. That is the secret to a perfect emulsion every single time.
