Ingredients for copycat blue cheese dressing
Six ingredients, one blender, restaurant-quality tangy creaminess in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Blue Cheese Crumbles 🧀 | ½ cup | Aged 6-12 months for bold flavor |
| Sharp White Cheddar Cheese 🧀 | ½ cup | Shredded, aged 6+ months preferred |
| Sour Cream 🥛 | ½ cup | Full-fat for creaminess (not low-fat) |
| Buttermilk 🥛 | ¼ cup | Cultured, not powdered |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light, fruity variety |
| Apple Cider Vinegar 🍎 | 1 tbsp | Not balsamic or white vinegar |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarsely cracked |
The blue cheese makes or breaks this—St. Agur blue cheese or Maytag blue from the deli counter are worth the splurge. Look for crumbles that smell funky and salty, not mildewed. Sharp cheddar? Cabot or Tillamook from the cheese case (not the pre-shredded bag)—freshly grated gives the best texture. Sour cream should be full-fat (the good stuff, not the light version), and buttermilk needs to be cultured (check the label). For the olive oil, California avocado oil works too, but olive adds that fruity depth. The vinegar? Apple cider gives the most authentic tang—Bragg is my go-to.
No blue cheese? Gorgonzola crumbles at half the amount get you close, but the flavor won’t be identical. Short on buttermilk? Mix 1 tbsp lemon juice + 1 cup milk (let sit 5 minutes). Want more tang? Add 1/2 tsp Dijon mustard or a splash of lemon juice. For a spicy kick, 1/4 tsp cayenne or a dash of hot sauce works. The dressing thickens as it sits—add 1 tsp milk if it gets too stiff. And if you’re making this ahead, cover with plastic wrap pressed directly on the surface to prevent a skin.
This keeps for 5 days in the fridge, sealed airtight. The flavor actually improves overnight as everything melds. For longer storage, freeze in 1-ounce portions—thaw in the fridge and whisk to recombine. I like to make a double batch and keep one in the fridge, one frozen. The dressing reheats beautifully—just give it a quick whisk after warming. And if you’re using it on salads, add it just before serving to keep the greens crisp.

Step-by-step instructions for copycat blue cheese dressing
Here's the exact method—creamy, tangy, and perfectly balanced every time.
👨🍳 Step 1: Whisk Together the Cheese and Buttermilk
In a medium bowl, combine the 0.5 cup blue cheese crumbles and 0.5 cup sharp white cheddar cheese using a whisk. I like to break up any large cheese clumps with my fingers first—this ensures a silky texture. Add the 0.25 cup buttermilk and whisk vigorously for 1-2 minutes until the mixture is completely smooth with no visible cheese chunks.
Here's the thing—blue cheese can be crumbly, so don't rush this step. You're looking for a paste-like consistency that will emulsify beautifully with the other ingredients. If you see any dry spots, add a splash of buttermilk to help dissolve them completely.
🥘 Step 2: Incorporate the Sour Cream and Olive Oil
Next, add the 0.5 cup sour cream and 0.25 cup extra-virgin olive oil to the cheese mixture. Whisk continuously for another 2-3 minutes until the dressing begins to thicken and take on a creamy, velvety texture. This gradual incorporation prevents the dressing from separating later.
The olive oil should be added slowly while whisking—this is where the magic happens. You'll notice the mixture transform from a thick paste to a luscious, pourable consistency. If it looks too thick at this stage, that's normal—we'll adjust the texture in the next step.
🍳 Step 3: Add Acid and Seasonings for Balance
Pour in the 1 tbsp apple cider vinegar and whisk for 30 seconds to distribute evenly. The vinegar brightens the flavors and cuts through the richness of the cheese. Add the 0.5 tsp diamond crystal kosher salt and 0.25 tsp freshly ground black pepper, whisking until fully dissolved.
Taste the dressing at this point—it should be tangy, slightly sharp, and rich but not overpowering. If it needs more acidity, add another ½ teaspoon of vinegar. For extra creaminess, you can whisk in 1-2 tablespoons of buttermilk (but don't exceed the original amount). The dressing should coat the back of a spoon without being gluey.
⏰ Step 4: Rest and Adjust for Perfect Texture
Let the dressing sit at room temperature for 10-15 minutes before using. This resting period allows all the flavors to meld together and the texture to stabilize. After resting, give it one final whisk to ensure everything is well combined.
If the dressing is too thick after resting, thin it with 1-2 tablespoons of buttermilk at a time until it reaches your desired consistency. For a lighter texture, you can also whisk in 1-2 teaspoons of extra-virgin olive oil. The dressing should be thick enough to coat vegetables or salad greens but still pour smoothly.
Pro Tips For Making Copycat Blue Cheese Dressing
- Whisk in stages: Start with the sour cream and buttermilk first—this keeps the mixture smooth instead of clumping when you add the cheeses. I learned this the hard way after scraping gummy lumps off my whisk (yes, it happens).
- Use room-temperature cheeses: Take the blue cheese and cheddar out of the fridge 20 minutes before mixing—they’ll blend more evenly and won’t turn the dressing grainy. Cold cheese is stubborn; warm cheese plays nice.
- Don’t rush the olive oil: Drizzle the EVOO in slowly while whisking, not all at once—this emulsifies the dressing instead of separating it into a sad, oily puddle. Think of it like a slow-motion pour, not a dump.
- Taste before adding salt: The blue cheese and cheddar are already salty, so taste the mix first—you’ll likely need less salt than you think. I’ve ruined batches by overdoing it, and trust me, you can’t fix it.
Health benefits of this dish
Protein Powerhouse
This dressing packs a surprising protein punch with 8 grams per 2-tablespoon serving, thanks to the blue cheese and sour cream. That’s nearly 40% of your daily protein needs in a single serving—great for keeping you full and satisfied.
The combination of casein (slow-digesting) and whey (fast-digesting) proteins in the cheese creates a balanced amino acid profile that supports muscle repair and satiety. 💪
Calcium Boost
Blue cheese and cheddar are both excellent sources of calcium, with this dressing delivering about 15% of your daily value per serving. Calcium isn’t just for bones—it plays a key role in muscle function, nerve signaling, and even maintaining healthy blood pressure.
The buttermilk adds extra calcium too, making this a sneaky way to boost your intake without drinking milk.
Healthy Fats
The extra-virgin olive oil and full-fat sour cream provide monounsaturated fats, which support heart health by improving cholesterol levels. These fats also enhance the absorption of fat-soluble vitamins like A, D, E, and K from your salad ingredients.
Just 2 tablespoons of this dressing contains about 12 grams of fat, but the right kind that your body needs.
Probiotics for Gut Health
Both buttermilk and sour cream contain live cultures that act as natural probiotics, promoting a healthy gut microbiome. These beneficial bacteria help with digestion, nutrient absorption, and may even boost your immune system.
For maximum probiotic benefits, use uncultured buttermilk and ensure your sour cream is labeled as containing live cultures. ✨
Low-Carb Option
At just 2 grams of net carbs per serving, this dressing is naturally low in carbohydrates, making it a great fit for keto, low-carb, or Atkins diets. The fat content helps keep you full longer, reducing cravings for high-carb snacks.
For an even lighter version, you can replace the sour cream with Greek yogurt (but expect a slightly tangier flavor).
Rich in Vitamin K2
Blue cheese is one of the best dietary sources of vitamin K2, which works synergistically with calcium to strengthen bones and prevent artery calcification. A single serving of this dressing provides about 10% of your daily K2 needs.
This vitamin is often overlooked but plays a crucial role in cardiovascular health and metabolic function.

Frequently asked questions
Why does my dressing get grainy or separate?
This usually happens when the cheese isn't fully emulsified or the ingredients aren't combined slowly enough. Always whisk the cheese and buttermilk first until completely smooth, then add the sour cream and oil gradually. If it separates, whisk in 1 teaspoon of buttermilk at a time until creamy again. The resting period (10-15 minutes) also helps stabilize the texture.
Can I make this dressing ahead of time?
It actually tastes better after resting. Store it in an airtight container in the fridge for up to 5 days. The flavors meld beautifully overnight, and it keeps its creamy texture. For longer storage, freeze in 1-ounce portions—thaw in the fridge and whisk to recombine before using.
How do I adjust the tanginess or thickness?
For more tang, add ½ teaspoon extra vinegar or a splash of lemon juice. If it's too thick, thin with 1 tablespoon buttermilk at a time. Need it richer? Whisk in 1 teaspoon olive oil. The dressing should coat a spoon without being gluey—adjust gradually to avoid over-diluting.
What's the best cheese substitute if I can't find blue cheese?
Use ½ cup Gorgonzola crumbles (it's milder but similar) or ½ cup Roquefort. For a non-blue cheese option, blend ½ cup sharp cheddar + ¼ cup crumbled feta, but the flavor won't be identical. Always shred cheeses yourself—pre-shredded versions contain anti-caking agents that make the dressing grainy.
Is this dressing keto-friendly?
Yes! With only 2 grams net carbs per serving, it fits perfectly into keto, low-carb, or Atkins diets. The high fat content from cheese and olive oil keeps you full, and the probiotics from buttermilk support gut health. For extra fat, add 1 tablespoon heavy cream per serving—just whisk it in before using.
