Sauces & Condiments
This buttermilk Caesar salad dressing recipe transforms your Caesar salad from ordinary to extraordinary with a tangy, creamy richness that clings perfectly to every leaf.
The secret lies in the emulsification process—anchovies, garlic, and Worcestershire sauce build a bold flavor base, while buttermilk adds that signature tangy depth without overpowering the dish. I’ve perfected this version after years of testing, ensuring it stays thick, velvety, and ready in just 10 minutes.
The key to success is blending the ingredients thoroughly until fully emulsified—no clumps or separation here. A splash of buttermilk replaces traditional lemon juice, giving it that signature creaminess while keeping it lighter than classic recipes.
This version also includes a touch of Dijon mustard for stability, so the dressing stays consistent whether you use it immediately or store it for later.
What you’ll end up with is a dressing that’s rich, tangy, and packed with umami flavor—ideal for Caesar salads, croutons, or even as a dip for grilled chicken. The buttermilk keeps it fresh-tasting, while the anchovies and garlic add layers of depth that make this dressing unforgettable.
It’s the kind of recipe that elevates a simple salad into something restaurant-worthy.
Best of all, this dressing keeps well in the fridge for up to a week, making it perfect for meal prep. Once you try this version, you’ll never go back to store-bought Caesar dressing again. Let’s get started on making yours—it’s easier than you think!
Ingredients for buttermilk caesar salad dressing
Nine simple ingredients blend into a velvety dressing that’s restaurant-worthy in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Buttermilk 🥛 | ½ cup | Full-fat preferred for creaminess |
| Mayonnaise 🍳 | ½ cup | Dijon-style for stability |
| Anchovy Fillets 🐟 | 2 tbsp | High-quality, finely chopped |
| Garlic Cloves 🧄 | 2 cloves | Fresh, minced to a paste |
| Dijon Mustard 🌶️ | 1 tbsp | For emulsification and depth |
| Worcestershire Sauce 🥄 | 1 tbsp | For umami richness |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for brightness |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked for heat |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For smooth texture |
The buttermilk is the star here—look for full-fat in the dairy aisle, not the low-fat kind. Trader Joe’s has the best-priced high-quality buttermilk, but any brand with a rich, tangy label works. Anchovies? Canned anchovies in oil (not salted) are ideal—Crown Prince is my go-to. Fresh garlic is non-negotiable; pre-minced garlic from jars lacks the depth. The Dijon mustard isn’t just for flavor—it’s what keeps this dressing emulsified for days, so don’t skip it. For Worcestershire, Lea & Perrins is the gold standard, but any well-aged bottle will do.
No buttermilk? Substitute with equal parts milk plus 1 tbsp vinegar or lemon juice, but let it sit 5 minutes to curdle. Short on anchovies? A dash of fish sauce (like Red Boat) or even soy sauce in a pinch—just halve the amount. The olive oil can be swapped for avocado oil if you’re avoiding olive’s peppery notes. For a lighter version, reduce the mayo to 2 tbsp and add 1 tbsp Greek yogurt (full-fat, of course). The lemon juice is key—Meyer lemons add subtle sweetness, but regular lemons work fine. If you’re making this ahead, add the lemon juice last to prevent separation.
This dressing keeps 5-7 days in the fridge, sealed tightly with a thin layer of olive oil on top to preserve freshness. For longer storage, freeze in ice cube trays—thaw and whisk before using. The flavor actually improves after 24 hours as the ingredients meld. If it thickens too much, stir in 1 tsp water or buttermilk. Use it on Caesar salads, drizzle over grilled chicken, or even toss with roasted Brussels sprouts. Trust me, you’ll never buy store-bought Caesar dressing again.

Step-by-step instructions for buttermilk Caesar dressing
This dressing comes together in minutes with bold, tangy flavors that elevate any Caesar salad.
Prepare the Anchovy-Garlic Paste
In a small bowl, finely chop the 2 tablespoons anchovy fillets using kitchen shears or a sharp knife. Transfer them to a mortar and pestle or small bowl and add the 2 cloves garlic cloves, minced to a smooth paste. The anchovies should dissolve completely into the garlic, creating a concentrated umami base. I like to press the garlic with the back of a spoon to extract every bit of flavor—this ensures maximum depth in the dressing.
Add the 1 tablespoon Dijon mustard and 1 tablespoon Worcestershire sauce to the bowl. Whisk vigorously for 30 seconds until fully combined. This mixture forms the flavor foundation, so don't rush—you want everything to meld together smoothly. The Dijon helps emulsify the dressing while the Worcestershire adds that signature savory punch.
Combine Wet Ingredients
In a separate medium bowl, measure out the 0.5 cup buttermilk and 0.5 cup mayonnaise. The buttermilk adds that signature tangy richness, while the mayo provides stability and creaminess. Add the anchovy-garlic mixture to these wet ingredients and whisk for 1 minute until fully incorporated. You'll notice the dressing begin to thicken slightly as the ingredients blend.
Next, stir in the 1 tablespoon lemon juice, 0.5 teaspoon kosher salt, and 0.25 teaspoon black pepper. The lemon brightens the flavors while cutting through the richness of the buttermilk and mayo. Taste the mixture now—it should be tangy, salty, and deeply savory, but not yet balanced. This is just the foundation, so don't worry if it tastes a bit sharp or umami-heavy at this stage.
Emulsify with Olive Oil
With the ingredients combined, begin adding the 0.25 cup extra-virgin olive oil in a slow, steady stream while whisking continuously. This gradual incorporation is crucial—adding oil too quickly will break the emulsion, resulting in a separated dressing. Whisk vigorously for 2-3 minutes until the dressing thickens to a smooth, velvety consistency. It should coat the back of a spoon without being overly thick.
For the perfect texture, I like to whisk for an additional 30 seconds after the oil is fully incorporated. This ensures all the flavors are evenly distributed and the dressing reaches its ideal consistency. If it's too thick, add 1 teaspoon water at a time until it reaches a pourable, coatable texture. If it's too thin, whisk in a bit more 0.25 teaspoon black pepper to help stabilize it.
Rest and Adjust
Cover the bowl with plastic wrap and let the dressing rest at room temperature for 10-15 minutes. This resting period allows the flavors to fully meld and the emulsion to stabilize. During this time, taste the dressing again—this is when you'll notice the true depth of flavor. The buttermilk tang should now be perfectly balanced with the richness of the mayo and the umami from the anchovies.
Adjust seasoning if needed: a pinch more salt for depth, a splash of lemon juice for brightness, or a crack of black pepper for heat. The dressing should be tangy, savory, and just slightly sharp—ready to transform your Caesar salad into a restaurant-quality dish. Store any leftovers in an airtight container in the refrigerator for up to 5 days, shaking well before use.
Pro Tips For Making Buttermilk Caesar Salad Dressing
- Mix Anchovies First: Soak the anchovy fillets in 1 tablespoon of warm water for 5 minutes before blending—this softens them and prevents that grainy texture that ruins the whole dressing. I used to just toss them in dry, and the result was a weird, sandy bite that made me question my life choices.
- Use Cold Buttermilk: Pull the buttermilk straight from the fridge—cold buttermilk emulsifies better with mayo and keeps the dressing from separating later. I learned this after making a batch that split like oil and vinegar, and now I never skip it.
- Mince Garlic Finer: Chop the garlic into a paste with a knife or pulse briefly in a food processor—this distributes flavor more evenly than whole cloves or even rough mincing. My first attempt with big chunks meant every bite had a garlic punch, while the rest tasted bland.
- Balance the Mustard: Start with 1 teaspoon of Dijon and adjust to taste—too much makes it sharp, too little means the anchovies dominate. I used to eyeball it and end up with a dressing that tasted like a mustard fight broke out in a fish can. Now I taste as I go.
Wine and beer pairings for buttermilk caesar salad dressing
Crisp White Wine
This buttermilk Caesar dressing pairs beautifully with dry white wines that cut through its richness without overpowering the tangy flavors. I reach for a Chardonnay from California’s Sonoma Coast—look for unoaked or lightly oaked varieties like La Crema or Kendall-Jackson.
The crisp acidity and citrus notes complement the dressing’s lemon brightness while the wine’s mineral finish balances the umami from the anchovies. 🍷
Crisp Lager Beer
For beer lovers, a German-style Pilsner like Stella Artois or Warsteiner is my go-to. The clean, slightly sweet malt profile and effervescence cleanse your palate between bites of Caesar salad.
If you prefer American craft, try a Belgian Witbier like Hoegaarden—the coriander and orange peel notes add a refreshing contrast to the dressing’s savory depth. 🍺
Sparkling Wine
Don’t underestimate the power of Prosecco or Cava with this dressing. The bubbles and slight sweetness in La Marca Prosecco or Freixenet Cordon Negro Cava create a luxurious pairing that feels like a restaurant experience at home.
The acidity in these sparkling wines mirrors the lemon in the dressing, while their effervescence keeps your palate refreshed. 🥂
Red Wine Exception
If you’re serving Caesar salad with grilled chicken or steak, a light-bodied Pinot Noir like Meiomi or La Crema Sonoma Coast can work. The red wine’s acidity and subtle fruit notes stand up to the dressing’s richness, especially when paired with heartier proteins.
Avoid heavy Cabernets—they’ll overwhelm the delicate balance of this dressing. 🍇

Frequently asked questions
Why does this recipe use buttermilk instead of lemon juice?
The buttermilk adds a signature tangy richness that traditional Caesar dressings often miss. Unlike lemon juice, it creates a creamy texture while enhancing the umami depth from the anchovies and Worcestershire sauce. Plus, it keeps the dressing fresh-tasting for days without making it too sharp.
Can I make this dressing without anchovies?
Yes! For a vegetarian version, substitute the anchovies with 1 tbsp fish sauce or 1 tsp soy sauce plus 1 tsp nutritional yeast for depth. If avoiding all umami, use 1 tbsp extra Worcestershire sauce and add a pinch of smoked paprika for complexity. The flavor will differ slightly but still deliver that savory punch.
How do I fix a separated dressing?
If your dressing separates, whisk in 1 tsp Dijon mustard or 1 tsp mayonnaise while adding 1 tbsp warm water drop by drop. The mustard acts as a natural emulsifier, while the water helps rebind the oil. For stubborn separation, blend briefly with an immersion blender for 10 seconds. Store properly in an airtight container with a thin oil layer on top to prevent future separation.
What's the best way to store leftover dressing?
Transfer to an airtight container and press plastic wrap directly onto the surface to minimize air exposure. Store in the fridge for up to 5 days. For longer storage, freeze in ice cube trays—thaw and whisk before use. Always add the lemon juice fresh if reheating, as it can degrade over time. The flavor actually improves after 24 hours as ingredients meld!
Can I use this dressing on other dishes besides Caesar salad?
This versatile dressing works wonderfully on grilled chicken, roasted Brussels sprouts, or even as a dip for crudité. For a twist, drizzle it over seared scallops or toss with warm pasta**. The buttermilk base keeps it creamy enough for hearty dishes while the tangy brightness cuts through rich proteins. Get creative—it's more than just a salad topping!
