Sauces & Condiments
This copycat blue cheese dressing recipe delivers the same velvety, tangy swirls you crave from your favorite restaurant—without the hefty price tag. The secret lies in balancing sharp blue cheese crumbles with buttermilk and mayo for that signature creamy yet slightly thick texture.
I’ve perfected this version over years of testing, ensuring every batch achieves that perfect harmony of tangy, salty, and rich flavors.
What sets this recipe apart is its simplicity: just five ingredients and 10 minutes of active time, yet it delivers restaurant-quality results. The key technique involves whisking the ingredients slowly to create a smooth emulsion—no lumps, just velvety perfection.
This dressing isn’t just for salads; it elevates fried chicken, tacos, or even mashed potatoes with its bold, complex flavor.
The texture is where this recipe truly shines—thick enough to cling to greens but still pourable, with a slight tang that cuts through richness. The blue cheese crumbles dissolve into tiny, flavorful bites, while the buttermilk adds just enough acidity to balance the richness.
Once you try this version, you’ll never go back to store-bought again.
For extra versatility, adjust the thickness by adding more buttermilk for a lighter drizzle or a splash of mayo for a richer consistency. Store any leftovers in an airtight container in the fridge for up to five days, though it rarely lasts that long. Let’s make this dressing!
Ingredients for copycat blue cheese dressing
Five ingredients transform into restaurant-worthy blue cheese dressing with velvety texture and perfect tang.
| Ingredient | Amount | Notes |
|---|---|---|
| Blue Cheese Crumbles 🧀 | 1 cup | Sharp blue cheese preferred |
| Mayonnaise 🥛 | ½ cup | Duck or avocado oil preferred |
| Buttermilk 🥛 | ½ cup | Cold for best emulsification |
| Dijon Mustard 🌶️ | 1 tbsp | High-quality for tang |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Fruity, peppery variety |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarse grind for texture |
| Lemon Juice 🍋 | 1 tsp | Freshly squeezed |
The blue cheese is non-negotiable—Gorgonzola Dolce or Stilton deliver the most complex flavor profile, but Wisconsin Blue works well too. Look for crumbles with visible moisture and vibrant blue streaks. Whole Foods and specialty cheese shops carry the best selections, though the pre-packaged blue cheese at Trader Joe's is surprisingly good for a quick fix. The mayonnaise should be high-quality—Hellmann's or Duke's are reliable, but duck or avocado oil mayo adds a luxurious richness. Store your mayo in the fridge to prevent oil separation, and use it within three months for optimal flavor.
No blue cheese? Substitute crumbled goat cheese with extra lemon juice—it won’t be identical, but the tang remains. Short on buttermilk? Sour cream thinned with milk works in a pinch, though the texture will be slightly heavier. The Dijon mustard is critical for emulsification—Maille or Amoy brands are worth the investment. For a lighter dressing, increase buttermilk by 1 tbsp and reduce mayo by the same amount. If you prefer a richer version, swap the olive oil for walnut oil, which adds a nutty depth that complements the cheese beautifully.
This dressing emulsifies best when whisked at room temperature, so let ingredients sit for 10 minutes before combining. Store in an airtight container with a thin layer of plastic wrap pressed directly onto the surface to prevent a skin from forming. Keeps for 5 days in the fridge—though it rarely lasts that long. For long-term storage, portion into ice cube trays, freeze, and transfer to a bag. Thaws in 10 minutes and maintains perfect texture. The lemon juice can be omitted if you prefer a milder tang, but it’s essential for balancing the richness in the original recipe.

Step-by-step instructions for copycat blue cheese dressing
This method delivers the signature velvety tang and rich texture of restaurant-quality blue cheese dressing.
Combine the Base Ingredients
In a medium mixing bowl, add the 0.5 cup mayonnaise and 0.5 cup buttermilk. Use a sturdy whisk to combine these ingredients until they're fully incorporated and smooth. The buttermilk should blend seamlessly into the mayonnaise without any visible streaks. This foundational mixture creates the creamy base that will carry the bold blue cheese flavor.
Next, add the 1 cup blue cheese crumbles to the bowl. Using the whisk, gently fold the crumbles into the mayonnaise mixture until they're fully distributed. Be careful not to overmix at this stage—just enough to break up any large clumps. The cheese should begin to dissolve into the mixture, creating a thick, marbled texture. This is where the dressing starts to develop its signature depth of flavor and complex tang.
Incorporate the Mustard and Seasonings
Add the 1 tablespoon Dijon mustard to the bowl and whisk vigorously to fully incorporate it into the mixture. The Dijon mustard adds a subtle tang that balances the richness of the blue cheese and enhances the dressing's overall complexity. Next, add the 0.5 teaspoon Diamond Crystal kosher salt and 0.25 teaspoon freshly ground black pepper. Whisk these seasonings into the mixture until they're completely dissolved and evenly distributed.
The salt and pepper serve as the flavor anchors in this dressing. The kosher salt enhances the blue cheese's natural saltiness, while the freshly ground black pepper adds a subtle heat that cuts through the richness. At this point, the dressing should have a thick, creamy consistency with visible swirls of blue cheese throughout. If the mixture appears too thick, you can proceed to the next step—it will emulsify further as you add the olive oil.
Emulsify with Olive Oil and Lemon Juice
With the mixer running on low speed, slowly drizzle in the 0.25 cup extra-virgin olive oil while continuing to whisk. The olive oil should be added gradually to prevent the mixture from breaking. As you add the oil, the dressing will begin to thicken and develop a glossy sheen. This emulsification process is critical—it creates the velvety texture that sets this dressing apart from ordinary blue cheese mixtures.
Once the olive oil is fully incorporated, add the 1 teaspoon lemon juice and whisk until the mixture is smooth and homogeneous. The lemon juice brightens the flavors and adds a subtle acidity that prevents the dressing from tasting overly heavy. The final texture should be thick yet pourable, with a luxurious, almost buttery consistency. Taste the dressing at this point and adjust the seasoning if needed—you may want to add a pinch more salt or pepper to achieve the perfect balance of tangy, salty, and creamy flavors.
Rest and Adjust for Perfection
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 texture to stabilize. During this time, the blue cheese will continue to dissolve slightly, deepening the dressing's richness. If the dressing appears too thick after resting, you can thin it with 1-2 teaspoons of cold water or additional buttermilk, whisking until smooth.
The dressing is now ready to use. Its velvety texture and complex flavor profile make it perfect for drizzling over salads, pairing with crisp vegetables, or serving as a dip for fresh bread. The key to its success lies in the careful balance of ingredients and the emulsification process—each step ensures the dressing remains creamy, tangy, and utterly irresistible. Store any leftovers in an airtight container in the refrigerator for up to 5 days, giving it a gentle stir before each use to restore its smooth consistency.
Pro Tips For Making Copycat Blue Cheese Dressing
- Whisk in Stages: Don’t dump all the buttermilk in at once—start with half, then mix in the rest while tasting. The dressing thickens as it sits, so adding liquid gradually keeps it smooth and prevents clumping. (Yes, even if you’re impatient like me.)
- Use Room-Temp Cheese: Cold blue cheese crumbles melt into the mayo unevenly and can turn the dressing grainy. Let the crumbles sit out for 10 minutes before mixing—just enough to soften them slightly. Trust me, it makes a real difference.
- Skip the Pre-Mixed Mayo: Store-bought mayo often has stabilizers that make the dressing too thick or separate later. Make your own mayo (just egg yolks, oil, and a pinch of mustard) or use a high-quality brand—your taste buds will notice the upgrade.
- Taste Before Adding Oil: The olive oil is the last step, but don’t just eyeball it. After blending everything else, taste the dressing first—you might need less oil than the recipe says. Sometimes, the buttermilk and mustard already bring enough richness.
Flavor customization for copycat blue cheese dressing
Herb-Infused Variations
Add 1 tablespoon chopped fresh dill or 1 teaspoon dried thyme for a bright, herbal twist that pairs beautifully with seafood salads or grilled vegetables. I often use 1 tablespoon finely chopped chives for a milder, oniony note that complements the tangy blue cheese without overpowering it.
For a Mediterranean flair, stir in 1 teaspoon dried oregano and a pinch of red pepper flakes—this version works wonderfully with roasted eggplant or bruschetta. 🌿
Spicy Kick Options
For heat lovers, blend in 1 teaspoon hot sauce (like Cholula or Tabasco) or ½ teaspoon cayenne pepper to intensify the dressing’s tang. I’ve also experimented with 1 teaspoon smoked paprika for a deeper, slightly smoky profile that elevates fried chicken or loaded baked potatoes.
If you prefer a sweeter heat, drizzle in 1 teaspoon honey or maple syrup to balance the spice. 🌶️
Thickness Adjustments
Need a lighter dressing for drizzling? Thin with 1-2 tablespoons cold water or buttermilk until it reaches a pourable consistency—ideal for Caesar salads or as a dip for veggie sticks.
For a richer, more luxurious version, reduce the buttermilk by 2 tablespoons and add 1 tablespoon sour cream or Greek yogurt to deepen the creaminess. This thicker version clings beautifully to hearty dishes like fried chicken tenders or steak bites.
Sweet & Savory Balance
Add a touch of sweetness with 1 teaspoon honey or maple syrup to mellow the tang, especially if you’re using a very sharp blue cheese. I’ve also found that 1 teaspoon minced shallots or garlic adds a savory depth that rounds out the flavors.
For a dessert-friendly twist, stir in 1 teaspoon vanilla extract and drizzle over cheesecake bites or fruit salads—the contrast of creamy and tangy is surprisingly delightful. 🍯
Regional Twists
For a Southern-inspired version, swap the Dijon mustard for 1 tablespoon yellow mustard and add ½ teaspoon smoked salt—perfect for fried green tomatoes or cornbread.
A French bistro adaptation calls for 1 teaspoon white wine vinegar and 1 teaspoon chopped tarragon to brighten the dressing, ideal for goat cheese crostini or charcuterie boards. 🗺️
Dairy-Free Adaptations
Replace the blue cheese with ½ cup crumbled dairy-free feta (like Violife) and the buttermilk with ½ cup unsweetened almond milk thinned with 1 tablespoon lemon juice. Use avocado oil mayo for a neutral base, and add 1 teaspoon nutritional yeast for a cheesy depth.
This version works well for vegan Caesar salads or as a dip for crudité. The texture will be slightly lighter but still creamy. 🌱

Frequently asked questions
Why does my homemade blue cheese dressing turn grainy?
The most common cause is overmixing the blue cheese crumbles, which creates lumps instead of dissolving them. Always whisk gently to break up large pieces, and let the dressing rest for 10-15 minutes—this allows the cheese to fully emulsify. If it still looks grainy, strain through a fine-mesh sieve for a silky texture.
Can I make this dressing without buttermilk?
Yes! Substitute with ½ cup sour cream thinned with 2 tablespoons milk for a tangier version, or use ½ cup plain yogurt for a lighter texture. The key is maintaining the same acidity level—if your substitute is too thick, add a splash of water or lemon juice to compensate.
How do I adjust the thickness of this dressing?
For a lighter drizzle, thin with 1-2 tablespoons cold water or buttermilk until pourable. For a richer, clingier version, reduce the buttermilk by 2 tablespoons and add 1 tablespoon sour cream or Greek yogurt. Always whisk thoroughly to restore the smooth emulsion.
What’s the best way to store leftovers?
Transfer to an airtight container and press plastic wrap directly onto the surface to prevent a skin from forming. It keeps for 5 days in the fridge—give it a gentle stir before using. For longer storage, freeze in ice cube trays, then transfer to a bag. Thaw in 10 minutes in the fridge and whisk to restore texture.
Can I use this dressing on non-salad dishes?
This versatile dressing elevates fried chicken, tacos, mashed potatoes, or even grilled steak. For a dessert twist, drizzle over cheesecake bites or fruit salads—the tangy-sweet contrast is unexpected but delicious.
