Quick Answer

What ingredients do I need?

Four simple items are enough:

• 1cup neutraltasting oil (avocado, olive, or MCT)
• 1 large egg, roomtemperature (or 2 yolks for extra silkiness)
• 2tsp fresh lemon juice (or 2tbsp if you like more zing)
• Pinch of salt, plus optional garlic or onion powder for flavor

What equipment works best?

If you have a whisk, youll be fine, but an immersion blender or a foodprocessor makes emulsification effortless. For anyone asking how to make mayonnaise without mustard in a blender, just pour the egg, lemon juice, and salt into the blender, start it on low, and slowly drizzle in the oil while the blades whirl.

How long does it take?

Prep takes about two minutes, emulsifying another three. Youll have a smooth mayo in roughly five minutes perfect for those rushed mornings or lastminute potlucks.

StepbyStep Method

Preparing the egg & oil

Start with a roomtemperature egg. The reason? Warm egg proteins expand faster, creating a stable emulsion. If you pull a cold egg straight from the fridge, the mayo may look grainy and can split. Whisk the egg lightly, then begin adding the oil a thin stream while you continuously whisk (or keep the blender on a low setting). Patience here is the key: a slow pour lets the fat coat each protein particle, which is why the mixture turns glossy rather than curdled.

Adding the acid & seasoning

Lemon juice does double duty it adds a bright citrus note and lowers the pH enough to act as a natural preservative. If youre curious about how to make mayonnaise without mustard and lemon juice, you can swap the juice for a splash of apple cider vinegar or even a pinch of cream of tartar. I usually stick with lemon because it balances the oils richness without the sharpness of vinegar.

Troubleshooting common issues

Split mayo? Dont panic. Whisk a fresh egg yolk in a clean bowl, then slowly incorporate the broken mayo into it. The fresh yolks emulsifiers pull everything back together.

Too thick or too thin? Adjust the oil ratio. More oil thickens; a teaspoon of warm water will loosen an overly dense batch. Remember, the texture should be similar to storebought mayo glossy and spreadable.

Ingredient DeepDive

Oil choices for keto

All three oils listed below keep the carb count at zero, but they each bring a distinct flavor and health profile.

Oil	Flavor	Key Nutrients
Avocado oil	buttery, mild	High in monounsaturated fats, vitaminE
Olive oil	fruity, slightly peppery	Rich in polyphenols
MCT oil	neutral, almost oilfree taste	Quick energy source for keto brains

Egg alternatives

If rawegg safety concerns you, choose pasteurized eggs (you can find them in most grocery stores). For a fully cooked version, try keto mayo with boiled eggs: mash two hardboiled yolks and blend them with the oil and lemon juice. The flavor shifts a little, but the texture stays luxurious.

Acid and emulsifier substitutes

When a recipe calls for mustard as the traditional emulsifier, you can replace it with:

• Fresh lemon juice (our goto)
• Apple cider vinegar a tangier note
• Cream of tartar a pinch works wonders in lowacid versions

Keto Benefits & Risks

Why this mayo fits a keto diet

Possible downsides

Raw eggs can harbor Salmonella, so always use fresh, refrigerated eggs and store the mayo in the fridge no longer than a week. Also, remember that fat is caloriedense a little goes a long way, so portion control helps keep your daily macros in check.

Allergy & dietary modifications

For those allergic to eggs, a simple aquafaba (the liquid from a can of chickpeas) mimics the emulsifying power of egg whites. Blend 3Tbsp aquafaba with the oil and lemon juice, and youll get a dairyfree, vegan mayo that still satisfies your keto macro goals.
