Classification Overview
Traditional homemade mayonnaise is an emulsion of egg yolks and oil, both of which are zero-carbohydrate ingredients, resulting in a near-zero carbohydrate condiment.
Primary Ingredients
Egg yolks contain approximately 0.5g carbohydrates per yolk. Pure oil (avocado, light olive, grapeseed) contains zero carbohydrates. Together these form the bulk of mayonnaise with negligible carbohydrate contribution.
Secondary Ingredients
Lemon juice contributes approximately 1g carbohydrate per tablespoon. Dijon mustard contributes approximately 0.5g per teaspoon. At the small quantities used per batch of mayonnaise, the per-serving contribution from these ingredients is approximately 0.1–0.2g.
Comparison with Commercial Mayonnaise
Standard commercial mayonnaise (Hellmann’s/Best Foods) made without added sugar contains approximately 0–1g carbohydrates per tablespoon and is also classified as compliant. Some commercial brands add sugar or modified food starch; homemade versions guarantee no added carbohydrates.
Summary
Homemade mayonnaise is classified as Allowed under standard keto guidelines. Its primary ingredients — egg yolks and oil — contain zero carbohydrates, resulting in approximately 0–0.5g carbohydrates per tablespoon. Published keto resources consistently list homemade mayonnaise as one of the most keto-compatible condiments. No added sugar, controlled ingredients, and high fat content make it well-suited for keto meal planning.

Homemade mayonnaise provides control over ingredient quality — particularly the oil used. Some commercial mayonnaise products add sugar or modified starch; homemade versions eliminate this concern.
Does homemade mayonnaise contain sugar?

Is aioli the same as homemade mayonnaise for keto?
Traditional aioli is an emulsion of garlic and olive oil, sometimes without egg. Modern aioli is often a garlic-flavored mayonnaise. Both contain near-zero carbohydrates from the same base ingredients as mayonnaise, and both are classified as Limited or Allowed (depending on any added non-compliant ingredients) under standard keto guidelines.
