Traditional vs. Commercial Caesar Dressing
The most significant factor determining whether a Caesar dressing contains raw eggs is its origin. A classic, homemade Caesar dressing, prepared in the traditional style, often relies on raw egg yolks. The yolks act as a critical emulsifier, binding the oil and acid to create the dressing’s characteristic creamy texture. Without this element, achieving the desired richness and consistency is difficult.
In contrast, virtually all mass-produced, store-bought Caesar dressings do not use raw eggs. Instead, they contain pasteurized eggs or other egg substitutes to eliminate the risk of foodborne illnesses like salmonella. The pasteurization process involves gently heating the eggs to a temperature that kills harmful bacteria without cooking the egg solids, making them a safe ingredient for commercial production. This process ensures consistency and extends the shelf life of the dressing, allowing for safe storage in the refrigerator for longer periods. For restaurants, the use of pasteurized products is often a food safety standard, though some high-end establishments may still use raw eggs in their proprietary, made-to-order versions.
Why Raw Eggs Are Used in Traditional Recipes
The emulsifying properties of raw egg yolks are what give homemade Caesar dressing its uniquely silky and rich consistency. When slowly drizzled oil is whisked into the egg yolk and acid (usually lemon juice), the lecithin in the yolk creates a stable emulsion. This process results in a thick, cohesive dressing that coats lettuce leaves beautifully. For purists, this method is an essential part of the authentic Caesar experience, capturing the essence of the recipe's improvisation by Caesar Cardini.
The Shift to Safer Commercial Alternatives
For most consumers, bottled Caesar dressing is the standard. This shift is driven primarily by food safety concerns and convenience. The risk of salmonella contamination, though relatively low, is a serious deterrent, particularly for vulnerable populations such as the elderly, pregnant individuals, and those with compromised immune systems. To protect public health, manufacturers use pasteurized eggs or safer emulsifiers like mayonnaise, which is itself an emulsion made with pasteurized eggs.
Comparison: Homemade vs. Bottled Caesar Dressing
| Feature | Homemade Caesar Dressing | Bottled Caesar Dressing |
|---|---|---|
| Egg Source | Often includes raw egg yolks | Always uses pasteurized eggs or substitutes |
| Emulsifier | Raw egg yolk and lecithin | Pasteurized eggs, mayonnaise, or stabilizers |
| Food Safety | Potential risk of salmonella; use fresh, high-quality eggs or pasteurized ones | Very low risk of foodborne illness due to pasteurization |
| Flavor Profile | Often bolder, fresher, and richer taste | Can be tangier, sweeter, or have a less complex flavor |
| Preparation | Time-intensive whisking to emulsify ingredients | Ready to serve; simply pour from the bottle |
| Shelf Life | Very short (typically 1-3 days refrigerated) | Significantly longer (weeks or months) |
Safely Enjoying Caesar Dressing: Tips and Alternatives
For those who love the creamy texture of Caesar but want to avoid the risks associated with raw eggs, several delicious and safe alternatives exist. Many home cooks now use mayonnaise as a shortcut, which is already a stable emulsion of pasteurized eggs and oil. This method delivers a creamy result with zero risk. Another popular option for a healthier, lighter version is using Greek yogurt or silken tofu, both of which provide a creamy base while also boosting protein. For an even thicker, more decadent dressing, some recipes call for hard-boiled egg yolks, which retain their emulsifying properties after being cooked.
Creating a Safe Homemade Caesar Dressing
If you prefer the control and flavor of a homemade dressing, using pasteurized eggs is the safest path. These are available in both liquid form and sometimes in-shell. They can be used just like raw eggs in a traditional recipe, providing the same emulsifying power without the salmonella risk. Another alternative is a recipe that relies solely on ingredients like Dijon mustard, which also acts as an emulsifier, to help bind the dressing. The flavor can be enhanced with key ingredients like anchovy paste, fresh garlic, and high-quality Parmesan cheese to maintain the classic Caesar profile.
Conclusion: Understanding Your Caesar Dressing
The presence of raw eggs in Caesar dressing is not a simple yes or no answer, but rather depends on its source. Traditional, homemade recipes often include raw egg yolks for their emulsifying properties, while nearly all commercial, bottled dressings contain pasteurized eggs or substitutes to ensure food safety. By understanding the distinction between these preparations, you can make an informed choice based on your health considerations and culinary preferences. Whether you opt for a store-bought bottle, use a mayonnaise base for a quick homemade version, or seek out pasteurized eggs for a traditional preparation, you can safely enjoy the bold, savory flavors that make Caesar salad a timeless favorite.

The Role of Anchovies
Contrary to popular belief, the original Caesar Cardini recipe did not include anchovies. The savory umami flavor came from Worcestershire sauce, which often contains anchovies itself. While many modern recipes now explicitly call for anchovy paste or fillets, this ingredient, much like the raw egg, is subject to variations and personal preference.
Food Safety for Vulnerable Groups
For pregnant individuals, young children, and the elderly, avoiding raw eggs is particularly important due to heightened susceptibility to foodborne illness. This is why public health organizations and medical professionals strongly advise against consuming homemade dressings with unpasteurized raw eggs. Choosing commercially produced dressings or making a safe alternative with pasteurized ingredients or substitutes is the recommended course of action.
Texture and Shelf Life Differences
The method of preparation not only affects the safety and flavor but also the dressing's texture and longevity. The natural emulsion of a raw egg dressing is delicate and will break down over time, limiting its refrigerated life to only a couple of days. Commercial dressings, with their stabilizers and pasteurized ingredients, are engineered for a much longer and more stable shelf life, remaining consistent over weeks or months.
