Avocado mayo is a blender-based condiment made from fresh avocado, egg yolks, and a slow drizzle of oil — same basic technique as regular mayo, but the avocado gives it body and a mild, creamy flavor that works especially well on burgers. It takes about 10 minutes, uses no heat, and fits gluten-free and paleo diets without any substitutions. If you keep avocados around anyway, this is a genuinely useful sauce to have in your back pocket.
What makes this version work
The key is treating this like a proper emulsion, not a dip. Blending the avocado and egg yolks together first creates a stable base before any oil goes in. Then the oil has to go in slowly — a thin, steady stream while the blender runs. Rush that step and the sauce breaks into a greasy, separated mess instead of a thick, cohesive mayo. The lime juice does double duty here: it helps the emulsion hold and slows the avocado from browning, which matters since avocado mayo oxidizes faster than standard mayo.
Ingredient notes
- Almond oil: Mild and works well, but it is pricey. A light-flavored olive oil or avocado oil are the most practical swaps — use extra-virgin olive oil only if you want a slightly bitter, more assertive flavor. Vegetable or sunflower oil works fine and keeps the cost low.
- Coconut oil: Use refined coconut oil if you do not want a coconut flavor in your mayo. Unrefined adds a noticeable sweetness. If you are out entirely, just increase the almond oil (or your swap) by the same amount.
- Pilli-pilli: This is a chili-based hot sauce or dried chili common in Central Africa. Crushed red pepper flakes, cayenne, or any hot sauce you already have will cover the heat here — start with a small pinch and adjust.
- Turmeric: Adds color and a faint earthiness. Skip it if you do not have it; the mayo still works. Do not substitute curry powder unless you want a much stronger flavor shift.
- Egg yolks: Use the freshest eggs you have, since the yolks are not cooked. If food safety is a concern, pasteurized eggs are a direct swap.
What can go wrong
- The mayo breaks and looks greasy: The oil went in too fast. If it separates, start with a fresh egg yolk in a clean cup, blend it briefly, then slowly drizzle the broken mixture into it as if it were oil — it usually comes back together.
- The mayo turns brown quickly in the fridge: Oxidation is faster with avocado than with standard mayo. Press plastic wrap directly onto the surface before sealing the container — air contact is the main culprit. Use within 2 days.
- The texture is too thin: The avocado was likely underripe. A firmer avocado has less water content and emulsifies more predictably. If it is already made and too loose, refrigerate it for 20 minutes — it will firm up slightly as the coconut oil cools.
- The flavor is flat: Avocado is mild by nature, so under-seasoning shows up immediately. Taste after adding the salt and lime, then adjust both before calling it done. A little extra lime juice makes a bigger difference than more salt here — skip adding extra oil to fix flat flavor, since that just dilutes everything further.
- The blender cannot get traction on a small batch: A standard blender jar is often too wide for a single batch. Use the tall, narrow cup that came with your blender or an immersion blender in a deep, narrow container — this is the right tool for small-volume emulsions.
Addictive Avocado Mayo Recipe
Ingredients
- 1 medium avocado
- ½ cup almond oil
- 2 tablespoons coconut oil
- 2 medium egg yolks
- 2 teaspoons turmeric
- 1 pinch salt
- 1 pinch ground black pepper
- 1 pinch pilli-pilli
- 1 medium lime
Instructions
- Squeeze out your lime and mix the lime juice with your avocado and egg yolks; it’s best to put all of the ingredients in one of those elongated measuring cups ( or the cup you got with your blender) as you will be blending these into a creamy paste.
- Once everything is blended, slowly add in the almond and coconut oil. ( like you would do with any other mayonnaise), this is where your patience needs to kick in. Keep it up until you’ve got everything blended, you’ll see that your sauce will get a thicker consistency, add in your pilli-pilli, salt and turmeric. There you go, you’ve done it.

Frequently asked questions
Can I make this without a blender?
Yes, but it takes more effort. Mash the avocado as smooth as possible, whisk in the egg yolks and lime juice until combined, then add the oil a few drops at a time while whisking constantly. The result is slightly less smooth than the blended version but still works well as a burger spread.
How long does avocado mayo keep in the fridge?
Two days is the practical limit. After that, the avocado oxidizes and the flavor turns bitter even if the surface looks fine — the lime juice slows this but does not stop it.
Can I use a whole egg instead of just the yolks?
Stick with yolks only — using a whole egg makes the mayo noticeably thinner and the texture less stable. Yolks have more lecithin, which is what actually holds the emulsion together.
My avocado is not quite ripe yet. Can I still use it?
A slightly underripe avocado will blend, but the mayo will be thinner and the flavor more grassy than creamy. If that is what you have, add an extra teaspoon of lime juice to help the blender break it down, and expect a looser final texture.
