StepbyStep Method

Ingredient List & Measurements

Measure everything precisely; small changes can throw off the emulsion.

• 2 large egg yolks (room temperature)
• 1tsp Dijon mustard (heaped)
• 1cup avocado oil or extravirgin olive oil for a keto mayonnaise recipe with olive oil
• 1tbsp freshly squeezed lemon juice (or apple cider vinegar)
• Pinch of sea salt (optional)

Equipment Youll Need

An immersion blender works like a magic wand, but a sturdy whisk or a food processor will do the trick. If youre using a blender, a tall, narrow container keeps the splash down.

How to Blend (ImmersionBlender Version)

1. Drop the yolks, mustard, lemon juice, and salt into the container.
2. Start the blender on low for about five secondsjust enough to combine.
3. While the blade whirs, drizzle the oil in a thin, steady stream. Patience is key; the mixture will thicken as the oil incorporates.
4. Continue blending until the sauce is glossy and holds its shape (roughly 3045 seconds total).
5. Give it a quick taste. Need more tang? Add a splash of lemon. Too salty? A dash more oil balances it out.

Variations You Might Love

• Keto mayo without mustard: Swap the mustard for a pinch of xanthan gum; it helps thicken without the flavor.
• Sugarfree mayo: No added sweeteners, just the natural carbs from the egg and lemonpractically zero.
• Eggfree version: Use aquafaba (the liquid from canned chickpeas) as the base, then follow the same oildrizzle technique.

Troubleshooting Tips

If your mayo breaks (oil separates), it usually means the oil was added too fast or the eggs were too cold. Warm the eggs to room temperature, slow the pour, and start the blender on the lowest setting. A broken batch can be rescued by whisking in a fresh egg yolk and slowly reincorporating the split mayo.

Why Avocado or Olive Oil?

Both oils are rich in monounsaturated fatsthink hearthealthy oleic acid. Compared with typical soybean or canola oils, they bring a buttery mouthfeel and a subtle, pleasant flavor. If you choose olive oil, youll notice a brighter, slightly peppery note that pairs beautifully with salads and grilled veggies.

Potential Risks & How to Stay Safe

Raw eggs can harbor Salmonella. The good news? The acidity from lemon juice (or a splash of vinegar) lowers the risk, and you can always opt for pasteurized eggs, which are heattreated without cooking them.

For those who arent on a keto plan, remember that the mayo is still high in fat. Portion control is keyone tablespoon makes a hearty dressing, but a whole cup can add up quick.

Frequently Asked Questions

Can I Substitute Avocado Oil With Olive Oil?

Absolutely. Olive oil gives a fruitier flavor and works just as well in the emulsion. Use a highquality extravirgin variety for the best taste.

Is This Mayo Truly SugarFree?

Yes. No sugar, honey, or sweeteners are added. The only carbs come from the egg yolk and a tiny amount from the lemonboth well under 1g per tablespoon.

Do I Need an Immersion Blender?

While an immersion blender makes the process nearly foolproof, a vigorous whisk or a food processor will also create a stable mayo. The main thing is to add the oil slowly while the base is already moving.

How Does Homemade Mayo Compare To StoreBought SugarFree Brands?

Store brands often contain preservatives, stabilizers, and hidden carbs. A quick glance at the label shows a sugarfree mayo can still have 12g carbs per serving, plus unpronounceable additives. Your homemade version is 100% transparentno mystery ingredients, no extra sugar.

What About Heinz? Is Their Mayo KetoFriendly?

Heinz Classic Mayo contains about 0.5g carbs per tablespoon, which technically keeps it under the lowcarb threshold, but the brand uses soybean oil and some added sugar. If youre strict keto, youll likely prefer the pure fats in avocado or olive oil.

Can I Make Keto Mayo Without Mustard?

Sure thing. Mustard acts as an emulsifier, but a pinch of xanthan gum or even a tiny bit of gelatin can do the job. The flavor will be milder, giving you more freedom to customize with herbs or spices.

Its easy to go overboard with salt or lemon. Taste as you go, and remember you can always add more laterbut you cant take it out.

Do	Dont
Use roomtemperature eggs.	Pour oil in a thick stream.
