Caesar Salad Dressing Recipe With Olive Oil: Rich Anchovy-Infused Creaminess

This Caesar salad dressing recipe with olive oil delivers the rich, umami-packed flavor that makes classic Caesar salads unforgettable. 💛 I developed it after years of testing—balancing anchovy depth, creamy texture, and bright acidity while letting the olive oil shine as the base.

The secret lies in proper anchovy infusion and emulsification, creating a dressing that clings perfectly to romaine without separating.

The foundation starts with high-quality olive oil, which carries the flavors while adding a subtle fruity note that traditional recipes often miss. We combine it with garlic, Dijon mustard, and Worcestershire for that signature tangy-savory punch, then finish with freshly grated Parmesan for nutty richness.

The anchovies dissolve completely, creating a smooth, cohesive dressing that's far more complex than store-bought versions.

What you'll end up with is a velvety, anchovy-infused dressing that's creamy yet balanced—just tangy enough to cut through rich toppings while maintaining that classic Caesar flavor profile. It stays emulsified for days, making it perfect for meal prep or gifting.

The olive oil base also makes this dressing more stable than traditional mayo-based versions, resisting separation even when stored.

This recipe serves as the perfect foundation for classic Caesar salads, crostini, or even as a marinade for grilled chicken. The dressing keeps well in the refrigerator for up to 5 days, with flavors deepening over time. Let's make dressing that rivals your favorite restaurant's—without the shortcuts.

Ingredients for caesar salad dressing recipe with olive oil

High-quality olive oil and anchovies form the heart of this velvety Caesar dressing.

The olive oil is non-negotiable—look for extra-virgin with fruity notes at specialty stores like Whole Foods or Trader Joe's. Anchovies should be high-quality, finely chopped—Brioschi or Colosetti brands are my go-to. Fresh garlic and Parmesan elevate the dressing beyond store-bought versions. For the buttermilk, Cultivate brand from the refrigerated section works best—it's tangier than regular milk. If you're short on time, plain yogurt mixed with a splash of lemon juice is a decent substitute, though it lacks the same creaminess.

No anchovies? Worcestershire sauce plus a dash of soy sauce mimics the umami, though you'll lose some depth. Swap Dijon mustard for regular yellow mustard if needed, but the coarse grind adds complexity. The buttermilk can be replaced with half-and-half plus 1 tsp vinegar, though texture will differ slightly. For a dairy-free version, unsweetened almond milk plus 1 tsp lemon juice works surprisingly well. Fresh lemon juice is ideal, but bottled works in a pinch—just add a pinch of sugar to mimic freshness. The Worcestershire sauce? Lea & Perrins is the gold standard, but any good brand will do.

This dressing stays emulsified for 5-7 days in the fridge, with flavors deepening over time. Store it in a glass jar with a tight seal—shake well before each use. For meal prep, divide into small containers so you're not shaking the whole batch. Freezes beautifully for up to 3 months—just thaw in the fridge overnight. The Parmesan will separate slightly when frozen, so give it a good stir after thawing. If it thickens too much, thin with a splash of olive oil or warm water to restore consistency.

Step-by-step instructions for Caesar salad dressing with olive oil

Here's how to create a velvety, anchovy-infused dressing that elevates every Caesar salad.

Heat the 0.75 cup extra-virgin olive oil in a small saucepan over low heat until it reaches 120°F—just warm enough to release the anchovies' umami without cooking. Add the 4 whole anchovy fillets and let them dissolve completely, about 2-3 minutes. This infusion transforms the oil into the dressing's flavor foundation.

Remove the pan from heat and stir in the 3 cloves garlic cloves, minced to a paste. Let the mixture sit for 5 minutes to steep—this allows the garlic's aromatic compounds to fully meld with the oil. You'll notice a subtle shift in scent, from fresh garlic to something deeper and more complex. Strain through a fine-mesh sieve into a clean bowl to remove any solids, leaving you with a rich, briny base.

To the warm oil mixture, add the 2 tbsp Dijon mustard and 1 tbsp Worcestershire sauce, whisking vigorously to combine. The Dijon adds a bright tang that cuts through the richness, while the Worcestershire deepens the umami profile. Add the 2 tbsp fresh lemon juice next—this balances the flavors with a sharp acidity that prevents the dressing from tasting too heavy.

Incorporate the 0.5 cup finely grated Parmesan cheese gradually, whisking constantly to prevent clumping. The cheese should melt into the mixture, creating a thick, creamy consistency. If the dressing appears too thick at this stage, don't worry—it will emulsify further as we add the buttermilk. Taste and adjust seasoning with 0.5 tsp Diamond Crystal kosher salt and 0.25 tsp freshly ground black pepper—this is where you can fine-tune the balance of saltiness, acidity, and heat.

Slowly drizzle in the 0.25 cup buttermilk while whisking continuously. The buttermilk's natural acidity helps emulsify the dressing, creating a silky texture that clings beautifully to romaine leaves. Keep whisking for 2-3 minutes until the mixture thickens and becomes homogeneous. You'll see it transform from a loose sauce to a velvety, cohesive dressing that coats the back of a spoon.

Here's the thing—if the dressing starts to separate, simply whisk in 1-2 teaspoons of warm water to restore its smooth consistency. The buttermilk's fat content and the anchovy oil create a stable emulsion, but sometimes a little extra liquid helps. Let the dressing rest for 10 minutes before using—this allows the flavors to fully meld and the texture to set properly. The result should be a dressing that's rich, tangy, and perfectly balanced, ready to elevate your Caesar salad to restaurant-quality.

Troubleshooting perfect results

Oil Separation Fix

If your dressing separates after mixing, don't panic—this happens when oil and liquid phases split. The quick fix is to whisk in 1 tsp warm water or 1 tsp olive oil to re-emulsify. For stubborn separation, blend the dressing briefly with an immersion blender until smooth.

I've found that using extra-virgin olive oil with 0.05% acidity or less (check the label) helps prevent this issue from recurring. 💛

Anchovy Bitterness

Overcooking anchovies during infusion can make them bitter. Keep the oil at 120°F or below—never let it smoke. If you notice bitterness after mixing, balance it with 1 extra tbsp lemon juice or a pinch of sugar.

I once burned a batch by cranking the heat too high; the dressing tasted like anchovy soap. Trust me, low and slow is key here.

Too Thick or Too Thin

Texture issues usually stem from ingredient ratios. For a thicker dressing, whisk in 1 tbsp grated Parmesan or 1 tsp Dijon mustard. To thin it out, add 1 tsp warm water or 1 tsp olive oil while whisking continuously.
