This dressing brings the iconic Old Chicago flavor straight to your kitchen. I’ve perfected the blend of fresh herbs and tangy dairy to match the restaurant’s signature taste.
The secret is balancing creamy buttermilk and sour cream with a mix of dried herbs for that familiar depth. A touch of garlic and onion powder rounds out the profile.
Whisk it together in minutes, then let it rest to let the flavors meld. The result is a classic, versatile dressing that’s perfect for salads, dipping, or drizzling.
Store it in the fridge for up to a week—if it lasts that long.

The buttermilk and sour cream are key here. Whole Foods or Trader Joe’s have great full-fat options that give that rich, velvety texture Old Chicago is known for. I always check the dates on dairy—fresher means better flavor. The mayonnaise should be a quality brand like Duke’s or Hellmann’s; skip the cheap stuff (it tastes thin and watery).
No buttermilk? Whole milk plus 1 tbsp vinegar works in a pinch. Dried herbs can be swapped for fresh at one-third the amount. If you’re missing Dijon, yellow mustard is fine (just less tangy). The vinegar can be apple cider or lemon juice—both add nice brightness. Sugar can be omitted, but it balances the acidity.
This dressing keeps for 1 week in the fridge. Give it a good stir before using—it’ll separate a bit. Store in a sealed jar for easy shaking. Don’t freeze; the dairy will curdle.

Step-by-Step Instructions for Creamy Herb Dressing
This simple method brings together all your ingredients into a smooth, tangy dressing that tastes just like the restaurant version.
Step 1: Whisk Together the Creamy Base
In a medium bowl, combine the 1 cup Buttermilk, 0.5 cup Sour Cream, and 0.5 cup Mayonnaise. I like to start with these three because they form the creamy foundation of this dressing.
Whisk vigorously for about 30 seconds until the mixture is completely smooth and no streaks of mayonnaise remain. The buttermilk will thin it slightly, creating that perfect pourable consistency we want for a dressing.
Step 2: Add the Tangy and Sweet Elements
Next, add the 1 tbsp Dijon Mustard, 1 tbsp White Vinegar, and 1 tsp Sugar to the bowl. The mustard adds depth, the vinegar brings that signature tang, and the sugar balances everything out.
Whisk again for another 20-30 seconds until all the ingredients are fully incorporated. You’ll notice the dressing starts to thicken slightly as the sugar dissolves and the vinegar reacts with the dairy. This is exactly what we want.
Step 3: Incorporate the Herb Blend
Now, add all the dried herbs: 1 tbsp Dried Parsley, 1 tbsp Dried Dill, and 1 tsp Dried Oregano. These are the flavor powerhouses that give this dressing its classic herb profile.
Also add the 1 tsp Garlic Powder, 1 tsp Onion Powder, 0.5 tsp Salt, and 0.25 tsp Black Pepper. Whisk everything together for a final 30 seconds until the herbs are evenly distributed and the dressing looks uniform.
Step 4: Chill and Let Flavors Meld
Transfer the dressing to a jar or airtight container. Cover and refrigerate for at least 1 hour before using. This resting time is crucial—it allows the flavors to develop and the herbs to rehydrate slightly in the liquid.
I’ve found that 2 hours is ideal for maximum flavor, but if you’re in a hurry, 30 minutes will still give you good results. The dressing will thicken slightly as it chills, reaching that perfect creamy consistency.
Give it a good stir before serving, as the herbs may settle during chilling. This makes about 2 cups of dressing, perfect for serving 4 generous portions.
Pro Tips For Making Old Chicago Creamy Herb Dressing
- Chill Before Serving: Let the dressing sit in the fridge for at least 2 hours—this gives the dried herbs time to rehydrate and the flavors to meld properly. I learned this the hard way when my first batch tasted flat and one-dimensional.
- Use Full-Fat Sour Cream: Skip the low-fat version; the full-fat sour cream makes the texture richer and helps the dressing cling better to salads. Sounds obvious now, but I used to wonder why mine always seemed thin.
- Whisk, Don’t Stir: Use a whisk to combine the buttermilk, sour cream, and mayo—it breaks up any lumps and creates a smoother consistency than a spoon. My grandmother swore by this, and she was right.
- Bloom the Herbs: Mix the dried parsley and dill with a tablespoon of warm water for 5 minutes before adding them to the dressing. It’s a small step, but it wakes up the flavors and makes them taste fresher.
Best Sauces and Condiments for This Dish
Salad Enhancements
This dressing transforms a simple garden salad into a restaurant-quality dish. I love it on crisp romaine lettuce with cucumbers, tomatoes, and shredded carrots. The creamy texture clings perfectly to all the ingredients.
Dip for Veggies
Use it as a dip for fresh or roasted vegetables. I serve it with celery sticks, bell pepper strips, and broccoli florets for a healthy snack. The tangy flavor pairs especially well with the natural sweetness of raw veggies.
Sandwich Spread
Spread a thin layer on sandwiches or wraps for added moisture and flavor. It works particularly well with grilled chicken or turkey. I also use it in place of mayo on my BLTs for a refreshing twist.
Marinade Booster
Thin it slightly with extra buttermilk and use as a marinade for chicken or pork. The herbs and acidity tenderize while adding flavor. I’ve had great results with chicken breasts marinated for 4-6 hours. 💪
Pasta Salad Dressing
Toss with cold pasta, cherry tomatoes, and olives for a quick pasta salad. The creamy base coats the noodles beautifully. I like using rotini or penne because they hold the dressing well in their grooves.
Baked Potato Topping
Drizzle over loaded baked potatoes instead of sour cream. The herb notes complement the earthy potato flavor perfectly. I add a sprinkle of chives on top for extra freshness and color. 🌟

Frequently Asked Questions
Can I use fresh herbs instead of dried?
Yes! Use 1/3 the amount of fresh herbs since they’re more potent. Finely chop 1 tsp fresh parsley, 1 tsp fresh dill, and 1/3 tsp fresh oregano for best results.
Why does my dressing taste too thick?
Add 1-2 tbsp buttermilk and whisk until smooth. The consistency should coat the back of a spoon but still drip slowly. Chilling for 1 hour also helps achieve the perfect texture.
How long can I keep this in the fridge?
It stays fresh for 7-10 days in an airtight container. Stir before each use, as the herbs may settle. For best flavor, make it 1 day ahead to let the flavors meld.
Can I make this dairy-free?
Substitute unsweetened almond milk for buttermilk and vegan mayo for regular mayo. Use coconut yogurt instead of sour cream. The taste will differ slightly but still be delicious.
