Ingredients for broccoli salad dressing recipe with mayo
Eight simple ingredients transform into creamy ranch dressing that clings perfectly to broccoli.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥫 | ½ cup | High-quality, full-fat preferred |
| Buttermilk 🥛 | ½ cup | Unsweetened, full-fat for creaminess |
| Fresh Dill Weeds 🌿 | ¼ cup | Chopped finely, stems removed |
| Fresh Parsley Leaves 🌿 | ¼ cup | Chopped, bright green preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground for best flavor |
| Onion Powder 🧅 | 1 tsp | Not onion salt |
| Dried Chives 🌱 | 1 tsp | Or substitute fresh chives at 1 tbsp |
| White Vinegar 💧 | 1 tbsp | For tangy brightness |
| Honey 🍯 | 1 tbsp | Wildflower preferred for depth |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked for heat |
The mayo and buttermilk are your creamy foundation—Hellmann's or Duke's for mayo, and make sure buttermilk is full-fat for that velvety texture. Fresh herbs are non-negotiable here. Trader Joe's has the best pre-washed dill and parsley bundles, but any grocery store's produce section works. Look for herbs with vibrant color—no wilted stems. The garlic and onion powders? Penzeys has great options, but the regular grocery store stuff is fine. Just don't grab the stuff that's been sitting in the spice aisle for years—it loses punch fast.
No buttermilk? Substitute 0.5 cup sour cream thinned with 0.5 cup milk. Fresh herbs missing? Dried dill at half the amount works, but you'll lose that bright freshness. The honey can be swapped for maple syrup if you prefer. Apple cider vinegar works too if you don't have white vinegar. For extra tang, add a pinch of mustard powder. And if you're feeling fancy, add 1 tsp lemon juice for brightness—just don't skip the honey entirely, that sweetness balances the tang perfectly.
This dressing keeps beautifully—up to 1 week in the fridge sealed tight. I double the batch and store it in a glass jar with a tight lid. For meal prep, portion into small containers so you can grab exactly what you need. The flavors actually improve after a day or two as everything melds together. If it thickens too much, just stir in a splash of milk or water. And trust me, leftovers taste better than the first batch—it's magic how the flavors develop.

Step-by-step instructions for creamy ranch-style broccoli salad dressing
Here's how to blend this velvety dressing that clings perfectly to crisp broccoli florets.
👨🍳 Step 1: Whisk Together Wet Ingredients
In a medium bowl, combine the 0.5 cup mayonnaise and 0.5 cup buttermilk using a whisk. Start with gentle strokes to emulsify the mixture—this prevents separation later. The buttermilk adds that signature tangy creaminess that makes this dressing shine.
Next, stir in the 1 tbsp white vinegar and 1 tbsp honey until fully incorporated. The vinegar brightens the flavor while the honey rounds out the acidity. You'll notice the mixture becomes slightly thinner as you mix, which is normal—this creates the perfect balance for coating broccoli without making it soggy.
👨🍳 Step 2: Add Herbs and Seasonings
Fold in the 0.25 cup fresh dill weeds and 0.25 cup fresh parsley leaves using a rubber spatula. I like to press the herbs against the side of the bowl first to release their essential oils before mixing. This ensures every spoonful gets that vibrant herbal punch.
Add the 1 tsp garlic powder, 1 tsp onion powder, 1 tsp dried chives, 0.5 tsp salt, and 0.25 tsp black pepper all at once. Whisk vigorously for 30 seconds until the seasonings dissolve completely. The dried chives add subtle onion-like depth that complements the fresh herbs beautifully.
⏰ Step 3: Rest and Adjust Consistency
Let the dressing sit at room temperature for 5 minutes—this allows all the flavors to meld together. Taste it now and you'll notice the herbs need time to infuse fully. If the dressing is too thick for your preference, gradually whisk in 1-2 teaspoons of water at a time until it reaches a pourable consistency.
For extra richness, you can add 1-2 teaspoons of sour cream if you have it on hand (though our recipe doesn't call for it). The dressing should now have a velvety texture with just the right balance of tang, sweetness, and herbal brightness—perfect for tossing with crisp broccoli florets.
🥘 Step 4: Final Flavor Check and Storage
Give the dressing one final taste and adjust seasoning if needed. I usually add a pinch more salt or a crack of black pepper to taste. The dressing should be creamy but still light enough to coat broccoli without weighing it down.
Transfer to an airtight container and refrigerate for up to 5 days. The flavors actually improve as it sits, developing deeper complexity. When ready to use, give it a quick whisk before tossing with your broccoli salad—this ensures perfect clinging and distribution every time.
Pro Tips For Making Broccoli Salad Dressing Recipe With Mayo
- Whisk in Stages: Start by mixing the mayo and buttermilk alone—this prevents the herbs from turning the dressing into a chunky mess right away. Once smooth, fold in the chopped dill and parsley; stir just until combined. Overworking it after adding greens will bruise the leaves and make the dressing look sad.
- Pulse the Herbs: Don’t chop the dill and parsley with a knife—use a mini food processor or pulse them in a blender for 2-3 seconds. This breaks down the stems enough to release flavor without turning the dressing into a green sludge. (Yes, it’s lazy, but it works.)
- Taste Before the Garlic: Add the garlic powder last, after checking the dressing’s tang and salt balance. The buttermilk’s acidity can mask flavors, so taste first—you might need extra salt or lemon juice before the garlic even enters the picture.
- Chill It Properly: Let the dressing sit in the fridge for at least 30 minutes before tossing it with broccoli. The flavors meld, and the mayo firms up slightly, so it doesn’t turn the salad into a soggy disaster. (I learned this after a lunch where the dressing pooled at the bottom of the bowl.)
Creative variations of these flavors
Sweet & Tangy Twist
Swap the honey for 1 tbsp maple syrup and add ½ tsp ground cinnamon for a subtle sweetness that pairs beautifully with broccoli. This variation works surprisingly well with roasted sweet potatoes too—just add 1 tsp smoked paprika for depth. 🌟
Spicy Ranch Kick
For heat lovers, blend in ½ tsp cayenne pepper or 1 tsp hot sauce (like Cholula) with the wet ingredients. Add ½ tsp smoked salt to complement the heat. This version is perfect for spicy tuna salad or grilled chicken wraps.
Herb-Forward Variations
Swap the dill for 0.25 cup chopped cilantro and add ½ tsp ground cumin for a Mexican-inspired twist. Or try 0.25 cup chopped basil with 1 tsp lemon zest for an Italian-inspired dressing that works well with tomato-based salads.
Creamy Garlic-Lime
Boost the garlic flavor by adding 1 tbsp minced fresh garlic (instead of powder) and 1 tbsp lime juice instead of vinegar. This version shines on grilled shrimp or avocado salads—just add ½ tsp chili powder for extra zing.
Nutty Crunch Option
For texture lovers, stir in 2 tbsp chopped walnuts or pecans right before serving. The nuts add a satisfying crunch that contrasts perfectly with the creamy dressing. Keep the nuts separate until serving to maintain crispness.
Lighter Greek Yogurt Version
Reduce the mayo to ¼ cup and add ¼ cup plain Greek yogurt for a lighter, tangier dressing. Boost the herbs to 0.33 cup total fresh herbs and add ½ tsp dried oregano. This version pairs beautifully with grilled veggies or as a dip for pita chips.

Frequently asked questions
Can I make this dressing without buttermilk?
Mix 0.5 cup sour cream with 0.5 cup milk to replace the buttermilk. Let it sit for 5 minutes to thicken slightly before using. This keeps the dressing creamy while maintaining that tangy ranch flavor.
How do I keep the dressing from separating?
Emulsify the mayo and buttermilk first with gentle whisking, then add other ingredients slowly. Store it in an airtight container and refrigerate. If it separates, whisk vigorously to recombine. For extra stability, add 1 tsp Dijon mustard to the wet ingredients before mixing.
What's the best way to store leftover dressing?
Transfer to a clean, airtight glass jar or container and refrigerate. This dressing stays fresh for 5-7 days. For longer storage, freeze in 1-tablespoon portions—thaw overnight in the fridge before using. The flavors actually improve after 24 hours as everything melds together.
Can I use this dressing on other vegetables besides broccoli?
Yes! It works beautifully on cauliflower, green beans, asparagus, or even as a dip for carrot sticks or celery. For grilled veggies, add 1 tsp smoked paprika to the dressing for extra depth. The creamy texture complements crisp textures perfectly.
Why does my dressing taste too tangy?
The buttermilk and vinegar create the tang, but the honey balances it. If it's too sharp, add ½ tsp more honey or 1 tsp maple syrup and whisk well. For a smoother flavor, reduce the vinegar to ½ tbsp next time. Taste as you go—this dressing is highly customizable!
