Ingredients for copycat blue cheese dressing
Six dairy ingredients, four pantry staples. That’s all it takes for restaurant-quality blue cheese dressing.
| Ingredient | Amount | Notes |
|---|---|---|
| Blue Cheese Crumbles 🧀 | 1 cup | Real crumbles, not powdered |
| Buttermilk 🥛 | ½ cup | Full-fat for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat preferred |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity |
| Mayonnaise 🥫 | ¼ cup | Duck or avocado oil best |
| Fresh Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Dijon Mustard 🌶️ | 1 tsp | Mild or medium heat |
| Cayenne Pepper 🔥 | ¼ tsp | Adjust for heat preference |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
The blue cheese is non-negotiable—real crumbles (not powder) make all the difference. Whole Foods or specialty cheese shops carry the best brands like Maytag Blue or St. Agur Blue, but any quality blue cheese works. Look for crumbles with vibrant blue-green veins—that’s where the sharpness lives. The buttermilk and sour cream? Full-fat versions (trust me on this) give you that velvety texture. I grab mine from Trader Joe’s—their organic buttermilk is my go-to, and the sour cream is always creamy. If you’re using store-brand, shake the container before measuring to mix any separated cream back in.
No buttermilk? Substitute with 0.5 cup milk plus 1 tbsp vinegar—let it sit 5 minutes to curdle. Sour cream too thick? Thin it with a splash of milk. The olive oil matters here—avoid cheap brands that taste like soap. California avocado oil or Spanish olive oil (like Picual) work best. The mayo? Duck or avocado oil mayo adds richness, but regular works in a pinch. Fresh lemon juice is key—bottled won’t cut it. Want less tang? Reduce to 0.5 tbsp. The cayenne is optional but adds that signature kick—start with 0.25 tsp and adjust to taste.
This dressing stays creamy for 5-7 days in the fridge, but the flavor deepens after 24 hours. Store it in a glass jar (plastic absorbs odors) with a lid pressed tight. For meal prep, portion into small containers—perfect for salads, dips, or drizzling. Freezes beautifully for up to 3 months if you want to make a big batch. Just thaw in the fridge overnight and whisk to recombine. Pro tip: If it separates after chilling, just whisk vigorously until smooth again—it’ll come back together every time.

Step-by-step instructions for tangy creamy blue cheese dressing
This dressing comes together faster than you can say "wings night" - creamy, tangy, and packed with that signature blue cheese punch.
Whisk Together the Creamy Base
In a medium bowl, combine the 0.5 cup sour cream and 0.5 cup buttermilk. Let these sit for 2-3 minutes while you gather the rest of your ingredients. This brief resting period helps the dairy soften slightly, making the final dressing extra velvety. I like to use a whisk here rather than a fork - it incorporates air more gently and prevents lumps from forming.
Add the 0.25 cup mayonnaise and 0.5 cup extra-virgin olive oil to the bowl. The olive oil should be at room temperature - if it's straight from the fridge, let it sit for 10 minutes first. This ensures your dressing stays smooth and doesn't separate later. Give everything a gentle whisk until fully combined, but don't overdo it - you're not trying to make meringue here.
Incorporate the Blue Cheese and Seasonings
Sprinkle the 1 cup blue cheese crumbles over the mixture in small batches. Here's the thing - I've found that adding the cheese all at once can make the dressing too thick. By adding it gradually, you give each addition time to dissolve properly. Use a rubber spatula to fold the cheese in, pressing against the bowl's sides to ensure all the crumbles break down completely.
Next, add the 1 tbsp fresh lemon juice, 1 tsp Dijon mustard, 0.5 tsp sea salt, 0.25 tsp black pepper, and 0.25 tsp cayenne pepper. The lemon juice brightens the flavors while cutting through the richness. The mustard adds subtle tang and helps emulsify the dressing. Whisk everything together until you see no more dry spots of cheese and the mixture is completely smooth. You'll know it's ready when it coats the back of a spoon with a silky consistency.
Taste and Adjust for Perfect Balance
This is where the magic happens. Taste a small spoonful of the dressing straight from the bowl - no dipping required. The flavor should be complex: creamy from the dairy, tangy from the lemon and mustard, with a sharp blue cheese punch. If it needs more tang, add another ½ tsp lemon juice. For more creaminess, stir in 1 tablespoon sour cream. Need more blue cheese flavor? Add 1 more tablespoon of crumbles, breaking them up thoroughly.
For heat preference, adjust the cayenne pepper in ¼ teaspoon increments. Remember, you can always add more heat, but you can't take it out. Let the dressing sit for 5 minutes after adjusting - the flavors will meld and you might find it needs just a tiny bit more of something. The perfect dressing should be rich enough to coat wings generously but light enough to drip beautifully without being greasy.
Pro Tips For Making Copycat Blue Cheese Dressing
- Pulse Not Stir: Blue cheese crumbles don’t dissolve—they blend. In a food processor, pulse the cheese in short bursts with the buttermilk first (about 3-4 seconds on, 10 off) until you get a rough paste. Stirring by hand just makes it lumpy, and nobody wants gritty dressing. I learned this after serving a salad with texture like wet sand.
- Chill the Base First: Cold ingredients = smooth dressing. Place your buttermilk and sour cream in the fridge for 15 minutes before mixing—this prevents the mayo from breaking when you add the olive oil. Warm dairy and oil don’t play nice, and you’ll end up with a split dressing faster than you can say "ruined wedge salad."
- Measure the Oil: Drizzle the olive oil in slowly, a teaspoon at a time, while the processor runs. Too much at once and the dressing curdles like spoiled yogurt. I used to eyeball it and wondered why my dressing always tasted thin and greasy. Now I measure: ¼ cup max for a standard batch.
- Use Real Buttermilk: Powdered buttermilk substitute? Skip it. The tang matters. If you’re fresh out, mix 1 tablespoon vinegar or lemon juice into 1 cup whole milk, let it sit 5 minutes, then drain. The acidity mimics the real thing, and your dressing won’t taste like it’s missing something—because it won’t be. I tried the shortcut once; my roommate asked if I’d added baking soda.

Frequently asked questions
Why does my blue cheese dressing get lumpy?
Lumps happen when the blue cheese crumbles aren't fully incorporated. Always whisk gradually while adding the cheese in small batches. For extra smoothness, press the crumbles against the bowl's sides with a rubber spatula to break them down completely. If lumps appear later, blend briefly with an immersion blender—just a few pulses will fix it!
Can I make this dressing without buttermilk?
Mix ½ cup milk with 1 tablespoon vinegar or lemon juice, let it sit for 5 minutes to curdle, then use it 1:1 as a buttermilk substitute. The acidity helps emulsify the dressing just like real buttermilk. For extra tang, add an additional ½ teaspoon lemon juice to the recipe.
How do I keep the dressing from separating?
Separation usually means the oil and dairy aren't properly emulsified. Whisk vigorously for 2-3 minutes until the dressing coats the back of a spoon. For extra insurance, add 1 teaspoon Dijon mustard—it acts as a natural emulsifier. If it separates after chilling, whisk again until smooth. Store in a glass jar (not plastic) to prevent oil absorption.
What’s the best blue cheese for this recipe?
Look for Maytag Blue, St. Agur Blue, or Gorgonzola Dolce—these have the perfect balance of sharpness and creaminess. Avoid powdered blue cheese (it lacks depth) and overly soft varieties. The best crumbles have visible blue-green veins—that’s where the boldest flavor lives! For a milder taste, reduce the amount to ¾ cup.
Can I make this dressing ahead of time?
Yes! This dressing actually tastes better after 24 hours as the flavors meld. Store it in an airtight glass jar in the fridge for up to 5-7 days. For meal prep, portion into small containers—perfect for salads, dips, or drizzling. If it thickens, whisk in 1 tablespoon milk or water to restore creaminess. Freezes well for 3 months in ice cube trays!
