This recipe captures the essence of a classic New York deli experience without the trip across town. I developed this after years of trying to recreate that signature flavor balance at home.
Whitefish salad requires just a handful of quality ingredients and careful seasoning to achieve that distinctive taste. The key is using fresh, flaky whitefish and letting the flavors meld properly during chilling.
What emerges is a creamy, slightly smoky spread with the perfect texture for schmearing on a bagel or serving with crackers. It’s the kind of dish that tastes even better the next day.
Serve it as a brunch centerpiece or easy appetizer. Here’s how to make this deli classic in your own kitchen.
Ingredients for Zabar’s Whitefish Salad
Fresh whitefish, creamy bases, and bright herbs bring deli flavor home with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Whitefish Fillets 🐟 | 1 lb | Skinless, boneless, flaked after cooking |
| Mayonnaise 🥚 | ¾ cup | Full-fat for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat preferred |
| Yellow Onion 🧅 | ½ whole | Finely diced for texture |
| Celery Stalks 🌿 | 2 whole | Finely diced for crunch |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed for brightness |
| Dijon Mustard 🟡 | 1 tbsp | Smooth, not grainy |
| Fresh Dill 🌿 | 2 tbsp | Chopped, stems discarded |
| Capers 🫒 | 1 tbsp | Drained and rinsed |
| Smoked Paprika 🌶️ | ½ tsp | For subtle smokiness |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarse grind for texture |
| Olive Oil 🫒 | 1 tbsp | For cooking whitefish |
The whitefish is non-negotiable here—fresh, skinless fillets from a trusted seafood counter are key. Look for firm, translucent flesh with no fishy odor. I source mine from Whole Foods or a local fishmonger (ask for center-cut pieces). The mayo and sour cream should be full-fat for that rich, authentic texture. Hellmann’s or Duke’s for mayo, and any full-fat sour cream will do.
No fresh dill? Dried dill at one-third the amount works, but fresh is ideal. Capers can be swapped for chopped cornichons if needed. For a tangier kick, add extra lemon juice or a splash of white vinegar. If you can’t find smoked paprika, a pinch of liquid smoke (just a drop!) can mimic the flavor. The celery and onion add crunch—don’t skip them.
This keeps beautifully in the fridge for 4-5 days and often tastes better after a day as flavors meld. Store in an airtight container with plastic wrap pressed directly on the surface to prevent browning. Not ideal for freezing—texture changes too much.

Step-by-Step Instructions for Zabar’s Whitefish Salad
This method delivers the authentic deli experience with perfectly flaked fish and creamy, balanced dressing.
Step 1: Cook and Flake the Fresh Whitefish Fillets
Heat the 1 tablespoon olive oil in a skillet over medium heat. Add the 1 lb fresh whitefish fillets and cook for 4-5 minutes per side until the fish is opaque and flakes easily with a fork.
Transfer the cooked fillets to a plate and let cool completely. Once cool, gently flake the fish into ½-inch chunks using a fork, being careful not to break it into too-small pieces. This texture is essential for the salad’s signature mouthfeel.
Step 2: Prepare the Aromatic Base
Finely dice the ½ whole yellow onion and the 2 whole celery stalks until you have uniform, small pieces. The onion should be small enough to blend into the salad without overpowering any single bite.
In a large mixing bowl, combine the diced onion and celery with the 2 tablespoons fresh dill, 1 tablespoon capers, ½ teaspoon kosher salt, and ¼ teaspoon freshly ground black pepper. Stir to distribute evenly.
Step 3: Make the Creamy Dressing
In a separate bowl, whisk together the ¾ cup mayonnaise, ½ cup sour cream, 2 tablespoons lemon juice, 1 tablespoon Dijon mustard, and ½ teaspoon smoked paprika until smooth and fully combined.
The dressing should be tangy with a subtle smokiness from the paprika. Taste and adjust seasoning if needed, though the fish and capers will add additional saltiness to the final dish.
Step 4: Combine and Chill for Optimal Flavor
Add the flaked whitefish to the bowl with the onions and celery. Pour the dressing over the top and fold everything together gently with a spatula. Avoid overmixing to keep the fish chunks intact.
Cover the bowl and refrigerate for at least 1 hour to allow the flavors to meld. This chilling time is crucial for developing the depth of flavor that defines this classic deli salad. Serve chilled on rye bread or with crackers.
Pro Tips For Making Zabar’S Whitefish Salad
- Poach Don’t Boil: Gently simmer the whitefish in barely bubbling water—around 160°F—so it stays tender and doesn’t turn rubbery. I learned this the hard way after my first batch came out tough as shoe leather.
- Drain Well: After poaching, let the fish sit in a colander for 10 minutes to shed excess liquid—otherwise your salad ends up watery. Sounds tedious, but it actually changes the outcome.
- Grate the Onion: Skip the dice and grate the yellow onion instead; it blends seamlessly into the mix and mellows faster in the mayo-sour cream base. My grandmother swore by this, and she was right.
- Chill Before Mixing: Refrigerate the poached fish for at least 30 minutes before flaking and combining with other ingredients—it holds its shape better and absorbs the flavors more evenly. I skip this when I’m lazy, but the dish is noticeably better when I don’t.
Storing and Reheating This zabars whitefish salad
Refrigerator Storage
Transfer your salad to an airtight container and press plastic wrap directly on the surface to prevent browning. Store in the fridge at 40°F or below for up to 4-5 days. The flavors deepen beautifully overnight. ❄️
Freezing Not Recommended
I tested freezing this in my Boston apartment kitchen, and the texture became watery and separated upon thawing. The creamy dressing doesn’t hold up well to freezing temperatures, so I’d recommend avoiding this method entirely.
Serving from the Fridge
This salad is meant to be served chilled, straight from the refrigerator. Let it sit at room temperature for 10-15 minutes if you prefer a slightly softer texture, but don’t leave it out for more than 2 hours for food safety.
Reviving Leftovers
If your salad seems dry after storage, fold in 1-2 tablespoons of additional mayonnaise or sour cream to restore creaminess. Stir gently to avoid breaking up the fish chunks too much.

Frequently Asked Questions
Can I use canned whitefish instead of fresh?
Yes, but fresh gives the best texture and flavor. If using canned, drain well and pick through for bones. The flavor will be saltier, so reduce added salt in the recipe.
Why does my salad taste too fishy?
This usually means the fish wasn’t fresh. Always check for a clean, mild smell before cooking. Soaking fillets in milk for 20 minutes before cooking can help remove any strong flavors.
How can I make it lighter?
Substitute Greek yogurt for half the mayonnaise and sour cream. The texture will be slightly tangier but still creamy. Avoid non-fat versions as they can make the salad watery.
What’s the best way to serve this?
Traditionally on a bagel with cream cheese, but it’s also great on rye toast or with crackers. For a pretty presentation, garnish with extra dill or a lemon wedge.
