Aussie Potato Salad Recipe: Crisp Celery Crowns and Mustard-Anchovy Zing

This Aussie potato salad recipe delivers the crisp celery crowns and mustard-anchovy zing that makes it a backyard BBQ staple. The secret lies in perfectly cooked potatoes tossed with a tangy mayo base, finely chopped celery, and a bold blend of mustard and anchovies that creates unmistakable depth.

I've perfected this version after years of testing—it's the one that actually holds up through the heat and keeps guests reaching for seconds.

The foundation starts with waxy potatoes boiled until tender but still firm, then chilled to develop that satisfying bite. A classic Aussie touch is the celery, which we dice into fine "crowns" for maximum crunch, and the mustard-anchovy dressing that gives it that signature sharp, umami kick.

This isn't your average mayo-heavy salad—it's balanced with just enough vinegar to keep things bright and fresh.

What you'll end up with is a salad that's creamy yet crisp, tangy yet satisfying, with every component in perfect harmony. The anchovies dissolve into the dressing, adding savory complexity without overpowering, while the celery maintains its satisfying crunch even after hours in the sun.

This is the kind of potato salad that elevates any BBQ spread from good to legendary.

Serve it alongside grilled meats, slathered on burgers, or packed in lunchboxes—it's versatile enough for any occasion. The recipe scales beautifully too, so you can make a big batch for gatherings or keep a smaller version on hand for weeknight dinners. Let's get cooking!

Ingredients for aussie potato salad

Waxy potatoes, crisp celery crowns, and that signature mustard-anchovy tang—this Aussie salad is all about balance.

The potatoes are the backbone—Yukon Gold or red potatoes hold their shape best when boiled and chilled. Costco or grocery store pre-washed bags save time, but scrubbing them yourself ensures no dirt gets trapped. Look for firm potatoes with smooth skins—none of that sprouting or soft spots. For the celery, freshness matters most. The stems should snap crisply, not bend. I usually grab a bunch and chop all three stalks—it's worth the extra crunch. Anchovies can be intimidating, but Trader Joe's or Whole Foods carry them in small packs that dissolve perfectly into the dressing.

No anchovies? Two tablespoons of soy sauce plus a dash of fish sauce mimics that umami punch. Short on mayo? Greek yogurt mixed with a little mayo cuts the richness. The mustard can be swapped for Dijon or whole-grain mustard—just taste as you go. For the celery crowns, a sharp chef's knife and steady hand make all the difference. If you're feeling fancy, toss in a handful of chopped capers for extra briny depth. The red onion adds color and a mild bite, but skip it if you're serving kids—some folks just don't love that sharpness.

Potatoes stay fresh for 3 days in the fridge after boiling, but they're best eaten the same day for that perfect bite. The dressing keeps for 5 days in the fridge—make extra for sandwiches or burgers. Store the chopped celery and onion in a sealed container with a damp paper towel to keep them crisp. This salad tastes even better the next day as flavors meld, so double the batch if you're feeding a crowd. The eggs, if using, should be peeled and stored separately until ready to add.

Step-by-step instructions for Aussie potato salad

Here's how to craft this iconic Aussie dish with crisp celery crowns and bold mustard-anchovy dressing.

Place the 3 lb waxy potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp salt and bring to a rolling boil over high heat. Once boiling, reduce heat to medium and cook for 12-15 minutes until the potatoes are fork-tender but still hold their shape when pierced.

Drain immediately and transfer to a colander. Let them cool completely for 10 minutes, then gently shake the colander to rough up the potato skins slightly. This creates better texture for the dressing to cling to. I like to work in batches if needed, but don't skip this cooling step—warm potatoes will make the salad soggy.

In a medium bowl, dissolve the 4 whole anchovy fillets in 2 tbsp white vinegar using a fork. This creates the base for our signature tangy dressing. Add the 0.5 cup yellow mustard, 1.5 cups mayonnaise, 1 tbsp granulated sugar, and 0.5 tsp black pepper. Whisk everything together until smooth and fully combined.

Here's where the magic happens: the anchovies and vinegar cut through the richness of the mayo, while the sugar balances the acidity. I like to let this mixture sit for 5 minutes while I prep the remaining ingredients—this allows the flavors to meld slightly before coating the potatoes.

Cut the 3 whole celery stems into fine crowns—this means cutting each stem into ¼-inch thick slices, then chopping those slices into small pieces. You want bite-sized pieces that will stay crisp in the salad. Finely dice the 0.5 cup red onion into tiny pieces so it distributes evenly throughout.

I know it seems tedious, but these small pieces make all the difference. The celery crowns should be uniform in size so they cook evenly when tossed with the potatoes. If you're worried about bitterness, soak the onion pieces in ice water for 5 minutes before draining and adding to the salad.

In a large mixing bowl, gently fold together the cooled potatoes, mustard-anchovy dressing, celery crowns, and diced red onion. Start with half the dressing and mix carefully to coat the potatoes evenly. Add more dressing gradually until fully combined but still leaving some texture—you want the potatoes to be coated but not swimming in dressing.

Here's the thing—don't overmix. You want the potatoes to stay intact with some bite, not mashed. Taste and adjust seasoning if needed, adding a pinch more salt or pepper as necessary. The salad should have a bright, tangy flavor with a subtle umami kick from the anchovies.

Cover the salad bowl and refrigerate for at least 2 hours, preferably 4 hours or overnight. This chilling time allows all the flavors to meld together perfectly. The potatoes will absorb the dressing and become even more tender while maintaining their shape.

Before serving, chop the 4 whole hard-boiled eggs and sprinkle them over the top along with the 2 tbsp fresh dill. The eggs add a creamy contrast to the crisp celery and potatoes. Serve chilled with crusty bread or alongside grilled meats for the ultimate Aussie spread.

Dietary considerations for aussie potato salad

Gluten-Free Adaptations

This Aussie potato salad is naturally gluten-free, but always double-check your ingredients. The mayonnaise should be certified gluten-free (I recommend Hellmann's Gluten-Free or Best Foods Gluten-Free Mayo). The yellow mustard and anchovy fillets are typically gluten-free, but brands like French's or Mustard Branch label their products clearly.

For extra safety, swap regular mustard with Dijon-style mustard—it's usually gluten-free and adds a smoother texture. 🌾

Dairy-Free Options

For a dairy-free version, replace the mayonnaise with vegan mayo (like Hellmann's Vegan or Sir Kensington's) or a mix of Greek yogurt and lemon juice for brightness. The hard-boiled eggs can be omitted or replaced with chopped avocado for creaminess.

Keep the mustard-anchovy dressing the same—it's already dairy-free and provides that signature tang. The celery and onion remain unchanged, ensuring that crisp texture stays intact.

Vegetarian Modifications

This salad is already vegetarian-friendly, but you can boost its protein with additions like chopped chickpeas (½ cup, drained and rinsed) or crumbled tofu (½ cup, pan-fried for extra texture). For a smoky twist, stir in 1 tbsp smoked paprika or 1 tsp liquid smoke into the dressing.

The anchovies can be swapped for soy sauce or miso paste (1 tbsp each) to maintain that umami depth without fish. The eggs can be replaced with extra celery or diced bell peppers for color and crunch.

Low-Carb Adjustments

To make this salad lower in carbs, reduce the potatoes to 2 lb and add ½ cup diced cucumber or ½ cup shredded cabbage for volume and crunch. Swap the red onion for green onions (½ cup, finely chopped) to cut carbs further.

The dressing remains the same, but you can reduce the sugar to ½ tbsp if you're strict about carbs. The celery crowns stay a staple—they’re naturally low-carb and add that essential texture. 🥦

Allergen-Friendly Swaps

For egg allergies, skip the garnish or use chopped avocado or toasted pumpkin seeds instead. If anchovies are an issue, replace them with 2 tbsp soy sauce + 1 tsp fish sauce for umami.

For mustard allergies, use Dijon mustard (often safer) or apple cider vinegar + 1 tsp honey for tang. Always check labels on mayo and vinegar for hidden allergens like soy or sesame.

The salad’s core ingredients—potatoes, celery, and onion—are typically safe for most allergies, making this a versatile option.
