Salads
This vegan potato salad dressing transforms a basic side into a flavorful centerpiece with its herb-infused oil base and tangy mustard kick. The secret lies in balancing creamy vegan mayo with sharp Dijon mustard and bright lemon juice, creating a dressing that clings beautifully to every potato.
I developed this recipe after realizing traditional potato salad dressings often relied on mayo that wasn't plant-based, leaving a gap for something equally rich but cruelty-free.
The foundation starts with a simple yet powerful combination: extra-virgin olive oil infused with fresh herbs like dill and chives, which adds depth without overpowering. A touch of apple cider vinegar brightens the flavor profile, while a pinch of garlic powder and onion powder builds complexity.
What makes this dressing truly special is how it maintains its creamy texture while staying light enough to let the potatoes shine.
What you'll end up with is a velvety dressing that's rich enough to satisfy traditionalists but fresh enough to appeal to those seeking plant-based options. The herbs stay vibrant, the mustard provides that signature tang, and the oil base ensures it won't separate or turn greasy.
This isn't just a substitute—it's a dressing that elevates potato salad to new heights while keeping it completely vegan.
Perfect for meal prep or last-minute gatherings, this dressing keeps well in the refrigerator for up to a week, making it an ideal addition to your pantry.
Whether you're serving it with classic boiled potatoes or using it as a base for a veggie-packed salad, this recipe delivers restaurant-quality results at home.
Ingredients for vegan potato salad dressing
Herb-infused oil meets tangy mustard for a dressing that transforms basic potato salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity variety |
| Vegan Mayonnaise 🥫 | ½ cup | Store-bought or homemade |
| Fresh Dill 🌿 | ¼ cup | Chopped finely, stems removed |
| Fresh Chives 🌱 | ¼ cup | Chopped finely, stems trimmed |
| Dijon Mustard 🌶️ | 2 tbsp | High-quality, sharp variety |
| Apple Cider Vinegar 🍏 | 1 tbsp | Raw, unfiltered preferred |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Onion Powder 🧅 | ½ tsp | Freshly ground preferred |
| Fresh Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, strained |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
The herbs are everything here. Fresh dill and chives from the grocery store's refrigerated section (not dried) give that bright, fresh flavor. If you're at Whole Foods or a farmers market, grab the organic bunch—they're usually fresher. For the olive oil, California extra-virgin has the best fruity notes, but any good-quality brand works. The key is to chop the herbs finely so they blend in smoothly without chunks. I usually make a double batch of herbs and freeze half for next time—they keep well for 3 months in an ice cube tray.
No fresh herbs? Dried dill at one-third the amount works in a pinch, but it won't be as vibrant. Short on vegan mayo? Silken tofu blended with lemon juice and olive oil mimics the creaminess (trust me, it's genius). The Dijon mustard can be swapped for whole-grain mustard if that's what you've got, but it'll be slightly milder. For extra tang, add an extra teaspoon of apple cider vinegar. The garlic and onion powders are non-negotiable—they build that savory depth that makes this dressing special.
This dressing keeps beautifully in the fridge for 1 week if stored in an airtight container with a layer of oil on top to preserve freshness. I always make extra because it disappears fast—perfect for meal prep. If it thickens, just stir in a splash of water or extra lemon juice. And if you're feeling fancy, drizzle a little more olive oil on top before serving. It's that simple, and it makes everything taste like you put in real effort.

Step-by-step instructions for herb-infused vegan potato salad dressing
This dressing delivers bright, herby flavor with a perfect tangy balance—no mayo overload here.
Finely Chop the Fresh Herbs
Start by washing the fresh dill and chives thoroughly, then pat them completely dry with paper towels. Using a sharp chef's knife, finely chop the dill stems removed, creating tiny leaf pieces about the size of a pinhead. For the chives, trim the stems and slice them into tiny rings—this ensures even distribution throughout the dressing.
I like to work in batches for herbs like this—chop half the dill first, then taste as you go. The fresh herb flavor will brighten up the entire salad, so don't skimp. You'll need all 0.25 cup of each herb, finely chopped, for that signature herbaceous kick.
Whisk Together the Base Ingredients
In a medium mixing bowl, combine the 0.5 cup extra-virgin olive oil and 0.5 cup vegan mayonnaise. Add the 2 tablespoons Dijon mustard and whisk vigorously until fully incorporated. The mixture should become smooth and slightly thickened—this is your flavor foundation.
Next, add the 1 tablespoon apple cider vinegar and 1 tablespoon fresh lemon juice. Whisk again until everything is well combined. The vinegar adds that essential tang while the lemon juice brightens the whole dressing. This step is where the magic happens—all the flavors meld together beautifully.
Incorporate the Seasonings
Add the 0.5 teaspoon garlic powder, 0.5 teaspoon onion powder, and 0.5 teaspoon sea salt to the bowl. Whisk everything together until the seasonings dissolve completely. The garlic and onion powders provide subtle depth, while the sea salt enhances all the flavors.
At this point, taste the mixture. You might find it needs a bit more brightness or tang. If so, add a pinch more salt or another splash of lemon juice. Remember, you can always adjust the seasoning, but you can't take it out once it's in.
Fold in the Fresh Herbs
Gently fold in the finely chopped fresh dill and chives using a silicone spatula. Be careful not to overmix—you want the herbs distributed evenly but still visible for that fresh, vibrant look. The herbs should be fully incorporated, but you should still see little flecks throughout.
Once the herbs are evenly distributed, give the dressing one final taste. It should be creamy from the olive oil and mayo, tangy from the vinegar and lemon, and bright from the fresh herbs. If it's too thick, add a teaspoon of water or more lemon juice to reach your desired consistency.
Rest and Adjust Before Serving
Cover the bowl with plastic wrap and let the dressing rest at room temperature for 10 minutes. This allows all the flavors to meld together perfectly. While it rests, give it one more taste—flavors often develop more fully after resting.
If you find the dressing needs more tang, add another half teaspoon of apple cider vinegar. If it needs more richness, stir in another tablespoon of vegan mayonnaise. Once you're happy with the flavor, it's ready to be tossed with your vegan potato salad for a creamy, herby, tangy dressing that everyone will love.
Pro Tips For Making Vegan Potato Salad Dressing
- Whisk in the oil last: I used to add olive oil first, and the dressing always ended up greasy—no matter how much I stirred. Instead, mix the vegan mayo, Dijon, and herbs first, then drizzle in the oil slowly while whisking. That way, you control the texture and avoid a clumpy mess.
- Mince the herbs, don’t chop: Big dill fronds or chives just sit in the dressing like decorative garnish. Use a sharp knife or small scissors to finely mince them—aim for a paste-like consistency. This releases more flavor and blends seamlessly into every bite.
- Taste before the potatoes: Potatoes soak up everything, so if your dressing tastes bland now, it’ll stay bland later. Adjust salt, acid (a splash of lemon juice or apple cider vinegar), or Dijon to taste before mixing with the potatoes. Trust me, you’ll regret it if you wait.
- Let the dressing rest: This isn’t the prettiest method, but it’s the tastiest: Mix everything, cover, and refrigerate for at least 30 minutes. The flavors meld, and the texture thickens slightly—no weird separation, just a richer dressing. (Yes, even if you’re impatient like me.)
Essential equipment for great vegan potato salad dressing
Mixing Bowl Essentials
Start with a medium-sized mixing bowl—I prefer glass or ceramic because they keep flavors pure and don’t absorb odors like plastic. A stainless steel whisk is non-negotiable for blending the oil and mayo smoothly, while a silicone spatula helps fold in the delicate herbs without crushing them.
For measuring, a liquid measuring cup ensures accuracy with the olive oil and vinegar. 🥄
Herb Prep Tools
Invest in a sharp chef’s knife (like the Mercer Culinary Genesis) for chopping dill and chives—dull blades bruise herbs, releasing bitter flavors. A small cutting board (preferably bamboo) prevents slipping while you work.
For storage, I keep pre-chopped herbs in ice cube trays in the freezer—they thaw instantly and retain freshness. 🌿
Whisk and Storage Containers
A balloon whisk (like OXO Good Grips) is perfect for emulsifying the dressing without over-aerating it. For storage, use amber glass jars with airtight lids—they block light and preserve freshness for up to 1 week.
If you’re prepping ahead, a vacuum sealer extends shelf life to 3 months. 💡
Optional Upgrades
For a herb-infused oil base, a small saucepan and fine-mesh strainer let you gently heat the olive oil with herbs for extra depth. A microplane is handy for grating fresh garlic if you skip the powder.
And if you love tangy dressings, a pH meter helps balance acidity perfectly—though I usually eyeball it. 🔥
Budget-Friendly Swaps
No fancy tools? A fork works for whisking, and a mortar and pestle can crush dried herbs if fresh aren’t available. Store-bought vegan mayo (like Hellmann’s Vegan) is fine, but homemade versions with silken tofu elevate the texture. A spoon and small bowl suffice for mixing—just whisk vigorously! 💪

Frequently asked questions
Can I make this vegan potato salad dressing without fresh herbs?
Yes, but the flavor will be less vibrant. Use 1 teaspoon dried dill and 1 teaspoon dried chives (about 1/3 the fresh amount) and add them at the end. For extra depth, toast the dried herbs in a dry pan for 30 seconds to enhance their aroma before mixing.
How do I prevent the dressing from separating?
Whisk vigorously when combining the olive oil and vegan mayo to create an emulsion. If it starts to separate after resting, whisk again or add 1 teaspoon of Dijon mustard to help bind the ingredients. Store it in an airtight container with a thin layer of olive oil on top to preserve freshness.
What’s the best way to store leftovers?
Keep the dressing in an airtight container in the fridge for up to 1 week. For longer storage, freeze in ice cube trays (thaw in the fridge) or vacuum-seal for 3 months. Always add a splash of lemon juice before reheating to restore brightness.
Can I use this dressing for other dishes besides potato salad?
It works beautifully with vegan coleslaw, roasted veggies, or even as a dip for crudités. For heartier dishes, reduce the lemon juice slightly to mellow the tang. The herb-infused oil base also pairs well with grilled tofu or vegan burgers.
Why does my dressing taste too heavy or greasy?
This usually happens if the mayo-to-oil ratio is off or the herbs aren’t finely chopped. Reduce the vegan mayo by 1 tablespoon and add 1 extra tablespoon of lemon juice to lighten it. For extra freshness, increase the herb amount slightly (up to 0.3 cup) to cut through richness.
