After testing countless variations in my Boston kitchen, I've perfected a dry mix that delivers restaurant-quality results with just a sprinkle.

The measurements are precise—just tablespoons and teaspoons—to ensure perfect results every time.

What makes this seasoning truly special is its versatility. Use it as-is for a classic potato salad or experiment with variations like adding extra herbs for brightness or a pinch of smoked paprika for depth.

Ingredients for watkins potato salad seasoning

Nine simple spices transform your potato salad into picnic perfection every time.

The celery salt is non-negotiable here—Diamond Crystal gives that authentic tang you taste in classic Watkins salads. I always grab mine from Whole Foods or the bulk section at Trader Joe's—it's worth the extra penny for that signature flavor. For the herbs, Penzeys Spices has the best dried parsley flakes and chives, but the regular grocery store stuff works fine if it's fresh-smelling. Pro tip: if your spices smell like dust, toss them—even the best brands lose potency after six months. The smoked paprika? McCormick or Gourmet Garden are my go-tos for consistent quality.

No white vinegar powder? Dried lemon peel at half the amount gives a similar zing. Short on dill? Dried basil works in a pinch—just use half the quantity. Want more heat? Swap the smoked paprika for cayenne pepper at a quarter teaspoon. The mustard powder is key for that tangy bite—Stonewall Kitchen makes a great one if you can't find it in your local store. For a deeper herb profile, add extra dried chives or parsley (up to an additional tablespoon each). This blend is your flavor foundation, so don't skimp on the quality spices—they make all the difference in that first bite.

Store this mix in an airtight glass jar in a cool, dark place—it'll keep its magic for up to 6 months. I always make a double batch because once you try this, you'll never go back to store-bought seasoning. For extra convenience, portion it into small jars or silicone molds—just enough for one salad at a time. The vinegar powder might clump slightly, but a quick stir with a fork before using fixes that right up. This blend is the secret weapon in my Boston kitchen—just a sprinkle transforms ordinary potatoes into the star of every picnic table.

Step-by-step instructions for Watkins potato salad seasoning

This bold herb and vinegar blend captures the essence of classic picnic potato salad—simple yet spectacular.

In a medium mixing bowl, begin by adding the 3 tablespoons of celery salt and 2 tablespoons of black pepper. These foundational ingredients create the signature salty backbone that makes Watkins seasoning so distinctive. Use a wire whisk to break up any clumps in the celery salt—this ensures even distribution throughout your potato salad.

Next, incorporate the 1.5 tablespoons of dried mustard powder and 1.5 tablespoons of dried parsley flakes. The mustard powder delivers that signature tangy punch, while the parsley flakes add a bright, fresh herbal note. Whisk these dry ingredients together until fully integrated with the celery salt and black pepper mixture. You'll notice the blend immediately takes on a vibrant green hue from the parsley.

Pour in the 1 tablespoon of dried chives, 1 tablespoon of garlic powder, and 1 tablespoon of onion powder. These aromatic powders work together to create a complex flavor profile that mimics the depth you'd get from fresh herbs and alliums. The chives contribute a subtle onion-like sweetness, while the garlic and onion powders add savory warmth.

Use your whisk to thoroughly combine these ingredients with the existing mixture. You should see the blend darken slightly and develop a more cohesive texture. At this stage, give the mixture a quick sniff—you should detect the sharp aroma of garlic and onion powder mingling with the earthy notes of the celery salt.

Add the 0.5 tablespoon of dried dill weed and 0.5 tablespoon of smoked paprika. The dill weed brings that classic picnic potato salad freshness, while the smoked paprika introduces a subtle BBQ-inspired depth that elevates the blend beyond ordinary seasoning mixes. Whisk these ingredients together until they're evenly distributed throughout the mixture.

Here's where the magic happens: the smoked paprika will create a faint reddish tint in the blend, while the dill weed adds a bright herbal aroma. This combination is what gives Watkins seasoning its signature complexity—both smoky and fresh at the same time.

Finally, add the 0.5 tablespoon of white vinegar powder. This is the secret ingredient that captures the signature tang of classic Watkins potato salad seasoning. The vinegar powder will dissolve into the blend, creating a subtle acidic note that balances the richness of the other ingredients. Whisk vigorously for about 30 seconds to ensure complete integration.

At this point, your seasoning blend should have a rich, complex aroma with notes of herbs, garlic, onion, and that unmistakable tang. The texture should be fine and powdery, with no visible clumps. If you're making this for immediate use, you can proceed to mix it directly with your potato salad. For best results, though, transfer the seasoning to an airtight container for long-term storage.

Transfer your completed seasoning blend to an airtight container with a tight-sealing lid. This preserves the freshness and prevents moisture absorption that could clump the seasoning. Store in a cool, dark place—like your pantry—for up to 6 months, or in the refrigerator for up to 1 year for even longer shelf life.

When you're ready to use it, simply shake the container well before measuring out portions. This ensures you get an even distribution of all the flavor components in every serving. The seasoning will maintain its vibrant color and potent aroma when stored properly, guaranteeing that every batch of potato salad you make tastes like it came straight from a classic American picnic.

Pro cooking tips for this recipe

Whisk Like a Pro

Use a fine-mesh wire whisk—not a spoon—to combine these spices. I learned this the hard way when I tried stirring with a wooden spoon and ended up with stubborn clumps that ruined the texture.

A whisk creates a smooth, even blend that dissolves perfectly into your potato salad. For best results, whisk in circular motions for about 30 seconds between each addition to prevent separation. 💫

Spice Freshness Check

Before measuring, give your spices a quick sniff test. If they smell like dust or nothing at all, toss them—even the most expensive brands lose potency after 6 months.

I keep a small jar of spices in my fridge for extra freshness, especially the dried herbs like parsley and dill. For this recipe, Penzeys Spices or McCormick brands are my go-tos for consistent quality. Never skip this step—the flavor difference is night and day. 🌿

Vinegar Powder Hack

The white vinegar powder can be tricky to find, but don’t stress—dried lemon peel works in a pinch. Use half the amount (¼ tsp instead of ½ tsp) for a similar tangy kick.

If you’re making a large batch, consider adding 1 tsp of powdered citric acid for extra zing. The vinegar powder is what gives this blend its signature tang, so if you’re substituting, taste as you go. 🍋

Storage Secrets

Store your seasoning in an airtight glass jar—plastic can absorb odors and ruin the flavor. I like using amber-colored jars to block light, which helps preserve the herbs’ potency. For long-term storage, keep it in the fridge where it’ll last up to 1 year.

If you’re prepping for a picnic, portion the seasoning into small silicone molds—just enough for one salad at a time. This keeps everything fresh and ready to go. ❄️

Adjust for Heat

Want extra kick? Swap the smoked paprika for ¼ tsp cayenne pepper or add ½ tsp red pepper flakes. For a milder version, reduce the black pepper to 1.5 tbsp and add ½ tsp dried basil instead.

The beauty of this blend is how easily it adapts—just tweak the spices to match your taste. I once accidentally doubled the cayenne and still loved the result (though my family wasn’t as thrilled). 🌶️

Picnic-Perfect Prep

Make a double batch and store it in your car’s glovebox for spontaneous picnics. I keep a small jar in my beach bag too—just add it to cold potato salad right before serving.

The seasoning mixes best with room-temperature potatoes, so let your salad sit for 10 minutes after adding the blend. This ensures even distribution and maximum flavor impact. Trust me, your picnic guests will ask for the recipe. 🏖️
