Understanding the Basics: What's in Aioli?
Aioli is a classic Mediterranean sauce, traditionally made by emulsifying garlic, olive oil, and sometimes egg yolk. It is essentially a garlic-flavored mayonnaise. The ingredients of traditional aioli are all naturally low in carbohydrates:
- Garlic: A single clove of garlic contains approximately 1 gram of carbohydrates, a negligible amount when distributed across a batch of aioli.
- Olive Oil: Olive oil is pure fat and contains zero carbohydrates.
- Egg Yolk: Egg yolks are a source of fat and protein with almost no carbs.
- Lemon Juice/Vinegar: The small amount used for acidity contains a minimal number of carbs.
Because these core ingredients are so low in carbs, a true homemade aioli is a carb-conscious dieter's dream. For those on a keto diet, its high fat content also makes it an excellent source of healthy fats.
The Commercial Conundrum: Store-Bought Aioli
This is where the "carb free" question gets tricky. While authentic aioli is low-carb, many store-bought varieties are not. Mass-produced condiments often contain extra ingredients to extend shelf life, improve texture, and enhance flavor. These additives are the primary source of hidden carbohydrates.
Common high-carb additives include:
- Sugar and High-Fructose Corn Syrup: Added for sweetness and balance, these can significantly increase the carb count per serving.
- Modified Food Starch: Used as a thickening agent, this is a form of carbohydrate that can affect your daily intake.
- Maltodextrin: Another common filler and thickener derived from starch.
For this reason, relying on store-bought aioli without checking the label is a gamble for anyone managing their carb intake. Even brands marketed as 'lite' or 'healthy' can sometimes have added sugars to compensate for reduced fat.
Homemade vs. Store-Bought Aioli: A Comparison
To highlight the difference, here is a comparison table showing the nutritional profiles of a typical homemade aioli recipe versus a hypothetical store-bought version. The figures are based on a 1 tablespoon serving and are approximate values.
| Feature | Homemade Aioli | Store-Bought Aioli | Verdict for Low-Carb |
|---|---|---|---|
| Main Ingredients | Olive oil, egg yolk, garlic, lemon juice | Canola oil, soybean oil, water, egg, sugar, modified starch | Homemade offers transparent ingredients. |
| Carbohydrates | < 1g net carbs | 1-4g+ net carbs | Homemade is almost always lower. |
| Added Sugar | None | Often contains high-fructose corn syrup or sugar | Homemade is sugar-free. |
| Sodium | Minimal, from added salt | Can be higher due to preservatives | Homemade allows for sodium control. |
| Macros | Very low carb, high fat | Variable, may have higher carbs | Homemade is reliably keto-friendly. |
| Cost | Less expensive per serving | More expensive | Homemade saves money. |
Making Your Own Low-Carb Aioli
Making your own aioli at home is simple and ensures complete control over the ingredients and carb count. You will need a food processor, immersion blender, or just a bowl and whisk.
Ingredients:
- 1 large egg yolk
- 1-2 cloves garlic, finely minced or puréed
- 1/2 cup high-quality olive oil
- 1-2 tsp lemon juice
- Salt and pepper to taste
Method:
- Whisk the egg yolk and minced garlic together in a bowl.
- Slowly, drop by drop, begin adding the olive oil while whisking constantly. This is the key to creating a stable emulsion.
- As the mixture thickens, you can increase the oil flow to a thin, steady stream.
- Continue until all the oil is incorporated and the aioli is thick and creamy.
- Stir in the lemon juice, salt, and pepper to taste. For a richer flavor, consider using roasted garlic.
This method guarantees a delicious, low-carb condiment that can be enjoyed with confidence. For more great ideas on how to incorporate homemade aioli into a keto lifestyle, check out resources like Virta Health's low-carb recipes.

- Vegetable Dip: A perfect dip for raw vegetables like celery, bell peppers, and cucumbers.
Conclusion
So, is aioli carb free? No, not entirely, as garlic contains a minimal amount of carbohydrates. However, a traditional, homemade aioli is so low in carbs that it is an excellent and safe choice for ketogenic and low-carb diets. The most significant risk comes from store-bought varieties, which can hide added sugars and starches. The best approach is to make your own at home, ensuring full control over the ingredients and nutritional content. This allows you to enjoy the rich, creamy, and flavorful condiment without worrying about sabotaging your diet.
