Sauces & Condiments
This copycat blue cheese dressing delivers the same velvety tang and rich depth you’d find in a restaurant’s signature sauce—just with a few simple ingredients and precise technique.
The secret lies in balancing sharp blue cheese with creamy sour cream and buttermilk, then emulsifying it to perfection for that signature swirl. I’ve perfected this recipe after years of testing, ensuring every batch stays smooth, tangy, and impossible to resist.
The process is straightforward: blend the ingredients until silky smooth, then thin with buttermilk for that signature lightness. A splash of Worcestershire sauce and lemon juice adds complexity, while a pinch of garlic powder elevates the flavor without overpowering.
What sets this apart is the emulsification step—slowly incorporating the buttermilk while blending keeps the dressing from breaking, guaranteeing a creamy texture every time.
By the time you’re done, you’ll have a dressing that’s bold enough to stand up to crispy fried foods but versatile enough to drizzle over salads, tacos, or even as a dip.
The tangy, slightly sharp notes of blue cheese shine through, while the creaminess ensures each bite is rich and satisfying. This isn’t just a copycat recipe—it’s a restaurant-quality sauce you can make at home in 10 minutes with no special equipment.
Store it in the fridge for up to a week, or double the batch for meal prep. Whether you’re tossing it with greens or using it as a dip, this dressing will become a staple in your kitchen. Let’s get started on making it!
Ingredients for copycat blue cheese dressing
Nine simple ingredients transform into restaurant-quality blue cheese dressing in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Sharp Blue Cheese Crumbles 🧀 | 1 cup | High-quality, crumbly variety |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess |
| Buttermilk 🥛 | ½ cup | Cold for best emulsification |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity variety |
| Worcestershire Sauce 🍯 | 1 tbsp | For umami depth |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| Mayonnaise 🥫 | ¼ cup | Duck or avocado oil preferred |
The blue cheese is everything here. Wysinger Farm or Maytag Blue deliver that signature tang—avoid the pre-shredded stuff, which gets gummy. I always buy a wedge and crumble it myself (the good stuff, not the pre-packaged kind). For the sour cream, full-fat is non-negotiable—it emulsifies better and gives that velvety texture. The mayonnaise might seem odd, but it helps stabilize the dressing so it doesn’t break. Hellmann’s or Duke’s work perfectly, but avocado oil mayo adds a richer depth. Store your blue cheese in the coldest part of the fridge, wrapped tightly—it keeps for up to 2 weeks this way.
No Worcestershire? Soy sauce at half the amount works in a pinch, though it’ll taste slightly different. Short on buttermilk? Mix 0.5 cup sour cream with 1 tsp lemon juice—it’s the same science. The lemon juice can be bottled, but fresh is brighter. If you’re making this ahead, add the buttermilk just before serving to keep it from curdling. The garlic powder is subtle but essential—skip it only if you’re sensitive to garlic flavors. For a lighter version, reduce the mayo to 2 tbsp and add 2 tbsp extra olive oil (it’ll still emulsify beautifully).
This dressing keeps for up to 1 week in the fridge, sealed tightly in a jar. The buttermilk will separate slightly if stored longer than 3 days—just give it a quick whisk before using. For meal prep, I double the batch and portion it into small containers. It’s perfect for drizzling over fried chicken, tossing with salads, or even as a dip for veggies. If you’re feeling fancy, add a pinch of smoked paprika or a dash of hot sauce right before serving—trust me, it’s worth the extra minute.

Step-by-step instructions for copycat blue cheese dressing
Here's the secret to that iconic velvety, tangy dressing—simple steps for a perfect copy every time.
Whisk Together the Creamy Base
In a medium bowl, combine the 0.5 cup sour cream and 0.5 cup buttermilk. Use a whisk and move in gentle circular motions until these two ingredients are completely smooth and homogeneous. The buttermilk's slight tang will begin developing immediately, so work quickly to prevent curdling. This base forms the creamy foundation of our dressing, so take your time here—it's the most critical step.
Next, add the 0.25 cup mayonnaise and whisk vigorously for about 30 seconds until fully incorporated. The mayonnaise helps create that signature velvety texture while adding stability to the emulsion. If you notice any streaks remaining after whisking, don't worry—we'll blend everything together thoroughly in the next step. The mixture should now have a thick, almost pudding-like consistency with a pale yellow hue.
Incorporate the Sharp Blue Cheese
Gently fold in the 1 cup sharp blue cheese crumbles using a rubber spatula. Work slowly and carefully to avoid breaking up the crumbles too much—we want visible flecks of blue cheese throughout the dressing. The cheese should distribute evenly, giving the mixture a marbled appearance with pockets of deep blue color. This is where the dressing gets its signature flavor, so don't rush this step.
If you're using a particularly crumbly blue cheese, you might find some pieces resisting incorporation. That's normal—just press them gently against the bowl's sides with your spatula. The key is to maintain that perfect balance between smooth creaminess and textural contrast from the cheese. Once fully combined, the dressing should have a thick, spreadable consistency with visible blue cheese flecks throughout.
Add the Flavor Enhancers
In a separate small bowl, combine the 1 tablespoon Worcestershire sauce, 1 tablespoon lemon juice, 0.5 teaspoon garlic powder, 0.25 teaspoon Diamond Crystal kosher salt, and 0.25 teaspoon black pepper. This flavor packet is the secret to that authentic restaurant taste—don't skip any ingredients. The Worcestershire adds umami depth, the lemon brightens the tang, and the garlic powder provides a subtle aromatic backbone.
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 dressing from separating. You'll notice the mixture begin to emulsify as the oil incorporates, transforming from a thick paste into a smooth, pourable consistency. The dressing should now have a glossy sheen and be thick enough to coat the back of a spoon without being overly stiff.
Final Emulsification and Taste Adjustment
Transfer the dressing to a blender or food processor and blend for 15-20 seconds until completely smooth. This final blending step ensures a perfectly homogeneous texture without any remaining lumps or cheese streaks. The result should be a velvety, almost silky dressing with no visible texture—just that signature blue cheese flavor in every bite.
Taste and adjust the seasoning if needed. If the dressing tastes too tangy, add a pinch more salt. If it needs more depth, add another teaspoon of Worcestershire sauce. The dressing should balance sharp, creamy, and tangy flavors with just a hint of garlic's warmth. Once perfected, transfer to an airtight container and refrigerate for at least 1 hour before serving to allow all the flavors to fully meld together.
Pro Tips For Making Copycat Blue Cheese Dressing
- Whisk Slowly First: Blue cheese crumbles are stubborn—if you dump everything in and start whipping, you’ll end up with lumps. Start with just the sour cream and buttermilk, mix until smooth, then gradually fold in the cheese. I learned this the hard way after scraping cheese bits out of my salad for the third time.
- Use Cold Ingredients: Room-temperature sour cream and buttermilk turn this dressing into a greasy mess. Keep your dairy in the fridge until the very last minute, then chill the bowl in the freezer for 5 minutes while you mix. The texture stays thick and creamy—no thin, soupy disappointment.
- Measure Worcestershire Precisely: That little bottle is sneaky—one extra splash turns your dressing bitter. Stick to 1 teaspoon (or less if your blue cheese is extra sharp). Taste as you go; you can always add more, but you can’t un-bitter it.
- Finish with Oil in Stages: Drizzle the olive oil in three separate additions, whisking after each. This keeps the dressing emulsified longer, especially if you’re making it ahead. Skip the "dump-and-stir" approach—your dressing will split faster than a bad date.
Dietary considerations for these flavors
Dairy-Free Adaptation
For a dairy-free version, replace the sour cream and buttermilk with ½ cup full-fat coconut yogurt and ½ cup unsweetened almond milk (or coconut milk for richer texture). Use ½ cup dairy-free mayo like Just Mayo or Vegenaise instead of regular mayo.
The blue cheese becomes the star—opt for vegan blue cheese like Violife or Follow Your Heart brands. The dressing will have a lighter, slightly nuttier profile but still deliver that signature tang. 🌱
Gluten-Free Friendly
This recipe is naturally gluten-free since it contains no wheat-based ingredients. However, always double-check labels on Worcestershire sauce—some brands contain gluten. Annie's or Lea & Perrins gluten-free versions work perfectly.
The rest of the ingredients are inherently safe, so you can enjoy this dressing without worry. For extra assurance, I keep a bottle of certified gluten-free Worcestershire on hand. ✨
Lower-Calorie Version
To cut calories without sacrificing flavor, reduce the mayonnaise to 2 tablespoons and replace the remaining 1 tablespoon with light Greek yogurt. Use low-fat sour cream and non-fat buttermilk (or unsweetened almond milk). The dressing will still emulsify beautifully, though it may be slightly lighter.
For extra tang, add an extra ½ teaspoon lemon juice. This version drops calories by about 30% while keeping the bold flavor. 💪
Allergy Considerations
If you're avoiding dairy, see the dairy-free adaptation above. For egg allergies, ensure your mayo is egg-free (like Just Mayo) and use a mayo substitute if needed.
For soy allergies, skip the Worcestershire and replace with ½ teaspoon soy-free fish sauce or an extra ½ teaspoon garlic powder. Always check labels—some brands process ingredients in facilities with allergens. When in doubt, I opt for certified allergy-free brands like Primal Kitchen for mayo. 🛡️
Keto-Friendly Adjustments
This dressing is already keto-friendly as written, with only 3 grams net carbs per serving. To make it even lower-carb, use heavy cream instead of buttermilk (mix ½ cup heavy cream + 1 teaspoon lemon juice) and reduce mayo to 2 tablespoons.
The result is a richer, creamier dressing with minimal carbs. For extra flavor, add a pinch of nutritional yeast—it adds a cheesy depth without carbs. 🥑

Frequently asked questions
Why does my blue cheese dressing separate?
Separation usually happens when oil and liquid ingredients aren't properly emulsified. Always add the 0.25 cup olive oil slowly while whisking continuously. For extra stability, blend the dressing for 15-20 seconds after all ingredients are combined. If it separates later, whisk vigorously before using. The mayo in the recipe helps prevent this, but cold ingredients can cause issues—bring everything to room temperature first.
Can I make this dressing ahead of time?
Yes! Store it in an airtight container in the fridge for up to 1 week. The buttermilk may separate slightly after 3 days—just whisk before serving. For best flavor, let it sit at room temperature for 10 minutes before using to restore its creamy texture. The longer it sits, the more the blue cheese flavor develops.
What's the best blue cheese to use?
Look for a sharp, crumbly blue cheese like Maytag Blue or Wysinger Farm. Avoid pre-shredded cheese—it contains anti-caking agents that make the dressing gummy. For extra tang, use a mix of two types. The cheese should be at room temperature when adding it to prevent the dressing from getting too thick.
How can I make this dressing thicker or thinner?
For thicker dressing, reduce the buttermilk by 2 tablespoons and add 1 tablespoon extra sour cream. To thin it, add 1 tablespoon more buttermilk or 1 teaspoon water. If it's too thick after blending, let it sit at room temperature for 5 minutes—it often thins naturally. For extra creaminess, whisk in 1 teaspoon heavy cream at the end.
Can I use this dressing on hot dishes?
Not directly—heat will cause the dressing to separate and lose its velvety texture. Instead, drizzle it over hot dishes immediately before serving or serve it on the side. For cold dishes like salads or tacos, it works perfectly. If you're using it as a dip, chill the dressing first to maintain stability.
