Tartar Sauce
A bright, tangy, herb-flecked classic that transforms humble fish into something special — this quick no-cook tartar sauce balances creamy richness with briny capers, crunchy gherkins, and fresh parsley for a condiment that belongs on every fried fish lover's table.
Tartar sauce is one of those condiments that seems simple — and it is — but the difference between a good one and a great one comes down to texture and balance. Too many store-bought versions are gloppy, one-note, and cloying. This homemade version, made with a base of mayonnaise and low-fat quark (or sour cream), delivers the perfect ratio of creamy to tangy to briny. The onions, capers, and gherkins are chopped finely enough to distribute evenly but coarsely enough to provide little pops of texture and flavor in every bite. A brief rest in the refrigerator allows the flavors to meld and the onion to mellow, resulting in a sauce that is greater than the sum of its parts. It comes together in 10 minutes and keeps beautifully for several days — the kind of all-purpose condiment that belongs in permanent rotation.
Ingredient notes: Use low-fat quark (a fresh dairy product common in Europe) or full-fat sour cream — both provide tang without thinning the sauce excessively. Do not use nonfat sour cream or Greek yogurt, which can be too thick and sour. For the gherkins, use the small French-style cornichons if available; they have a superior crunch and vinegary snap. If using larger dill pickles, chop them very fine and pat dry with a paper towel to remove excess moisture.
- Chef's knife
- Cutting board
- Measuring spoons
- Small bowl
- Rubber spatula or spoon
- Fine-mesh strainer (optional, for draining capers)
- Airtight container for storage
- Prepare the onion (3 minutes). Peel the onion and cut it into very fine dice — about ⅛-inch (3 mm) pieces. The finer the dice, the better the onion integrates into the sauce without overwhelming each bite. If the onion is particularly sharp or pungent, rinse the diced onion in a fine-mesh strainer under cold water and pat thoroughly dry with paper towels. Pro tip: A sharp knife is essential for fine dicing without crushing the onion cells and releasing excessive sulfur compounds. If you are sensitive to raw onion, the 30-minute chilling step will also help mellow its bite.
- Chop the capers and gherkins (2 minutes). Drain the capers and chop them finely. Chop the pickled gherkins into pieces about the same size as the chopped capers — roughly ⅛-inch (3 mm). The goal is uniformity: a mix of large and small pieces leads to an uneven distribution of flavor. Pro tip: If your capers are large salt-packed ones (not brine-packed), rinse them thoroughly and soak in cold water for 10 minutes to remove excess salt before chopping.
- Prepare the parsley (1 minute). Rinse the parsley under cold water and shake or pat dry thoroughly. Chop the leaves and tender stems finely. Discard any thick, tough stems. Measure 2 loosely packed tablespoons. Pro tip: Wet parsley will make the sauce watery. Dry the leaves thoroughly between paper towels or in a salad spinner before chopping.
- Combine all ingredients (2 minutes). In a small bowl, combine the mayonnaise, low-fat quark (or sour cream), chopped onion, chopped capers, chopped gherkins, and chopped parsley. Stir gently but thoroughly with a rubber spatula or spoon until everything is evenly distributed. The sauce should look creamy with visible specks of green herbs and crunchy pickle pieces. Pro tip: Fold rather than stir vigorously — you want to combine without breaking the mayonnaise emulsion or crushing the gherkin pieces.
- Season (1 minute). Add the salt and a few grinds of black pepper. Stir gently to combine. Taste the sauce and adjust seasoning. It should taste bright, creamy, and savory with a noticeable tang from the pickles and capers. If the sauce tastes flat, add another pinch of salt and a few drops of lemon juice. Pro tip: The saltiness will vary depending on your capers and gherkins — salt-packed capers are much saltier than brine-packed ones. Start conservatively with the salt and adjust after tasting.
- Chill (30 minutes minimum). Cover the bowl with plastic wrap or transfer the tartar sauce to an airtight container. Refrigerate for at least 30 minutes before serving. This resting period is essential — it allows the flavors of the onion, capers, and herbs to meld with the creamy base, and it gives the onion time to mellow. The sauce will also thicken slightly as it chills. Pro tip: For the best results, chill for 1 to 2 hours. The sauce improves significantly with time — overnight is even better. The raw onion sharpness fades and the herb flavors infuse the cream base.
- Serve (1 minute). Stir the chilled sauce gently before serving. Spoon alongside fried fish, over seafood, or next to crispy potato wedges. The sauce should be thick enough to hold its shape on a spoon but soft enough to dollop easily.
- Alongside beer-battered fish and chips or crispy pan-fried fillets (cod, haddock, halibut, or sole)
- As a dip for potato wedges, french fries, sweet potato fries, or onion rings
- With steamed or chilled shrimp, crab cakes, or lobster rolls
- On fried oyster or clam po' boys
- Dolloped onto grilled salmon or trout
- As a spread for fish burgers or tuna melts
- Alongside roasted or grilled vegetables — especially artichokes, asparagus, or zucchini
- Fine dice is non-negotiable. Large chunks of onion or gherkin make the sauce difficult to use and create uneven bites. Take the time to cut everything into uniform ⅛-inch dice — the texture and distribution of flavors depend on it.
- Dry everything before adding. Wet ingredients (onion rinsed to mellow it, capers from brine, parsley from washing) will water down the sauce. Pat everything thoroughly dry with paper towels before combining.
- Chill to meld, not just to cool. The 30-minute rest transforms the sauce from a collection of separate ingredients into a cohesive, harmonious condiment. Do not skip it.
- Taste and adjust salt carefully. Capers, gherkins, and mayonnaise all contribute salt. Add the initial salt sparingly, then taste after chilling and adjust before serving.
- Scale the onion to your tolerance. If you love raw onion, use the full amount. If you prefer a milder flavor, use half the onion or swap in 2 tablespoons of finely chopped scallion (white and light green parts only).
- A squeeze of lemon brightens everything. If the sauce tastes a bit flat after chilling, a few drops of fresh lemon juice will lift it considerably.
- The fat ratio matters. A 50:50 mix of mayonnaise and quark/sour cream gives you the creaminess of full-fat mayo with the tangy brightness of fermented dairy. Adjust the ratio to your preference: more mayo for richness, more quark for tang.
| Mistake | Why It Hurts | The Fix |
|---|---|---|
| Using pre-chopped onion from a jar | The onion is soft, watery, and lacks the crisp texture and fresh bite needed | Always chop fresh onion — the texture and pungency are irreplaceable |
| Not drying the capers and gherkins | Excess brine dilutes the sauce and makes it thin and watery | Drain and pat dry with a paper towel before chopping |
| Over-salting before tasting | Capers and gherkins vary widely in saltiness; the sauce can become inedibly salty | Add salt sparingly at first, taste after chilling, and adjust |
| Using a blender or food processor | The gherkins and capers are pulverized into a paste, losing all textural contrast | Chop everything by hand with a knife — the uneven pieces are part of the charm |
| Skipping the chilling step | The onion is harsh and sharp, the herbs taste raw, and the flavors remain separate | Refrigerate for at least 30 minutes to let the flavors meld |
| Using dried parsley instead of fresh | Dried parsley has no flavor or color and adds a straw-like texture | Use fresh flat-leaf (Italian) parsley only |
- Herb Tartar Sauce: Add 1 tablespoon each of chopped fresh dill and chopped fresh chives along with the parsley. The dill adds a lovely anise-like note that pairs beautifully with salmon.
- Lemony Tartar Sauce: Add 1 teaspoon of fresh lemon zest and 1 tablespoon of fresh lemon juice along with the mayonnaise. The extra acidity brightens the sauce considerably.
- Spicy Tartar Sauce: Add 1 teaspoon of hot sauce (Tabasco or Crystal) and ¼ teaspoon of cayenne pepper. For extra heat, include ½ finely minced jalapeño (seeds removed).
- Dijon Tartar Sauce: Whisk 1 teaspoon of Dijon mustard into the mayonnaise base before adding the other ingredients. The mustard adds a gentle heat and helps emulsify the sauce.
- Creamy Tartar Sauce (no mayo): Substitute the mayonnaise with an equal amount of full-fat Greek yogurt blended with 1 tablespoon of olive oil. The result is lighter, tangier, and dairy-forward.
- Caper-Lemon Tartar Sauce: Double the capers to 2 teaspoons and add 1 tablespoon of capers brine along with the lemon juice for an extra-briney, punchy version.
- Smoked Tartar Sauce: Add ¼ teaspoon of smoked paprika and ½ teaspoon of liquid smoke for a deeply savory, barbecue-adjacent condiment that pairs beautifully with grilled fish.
| Storage Method | Details |
|---|---|
| Refrigerator | Store in an airtight container for up to 5 days. The sauce will thicken slightly as it sits. |
| Best Before | Peak flavor is after 2 to 24 hours — the onion mellows and the herb flavors fully infuse the cream base. |
| Reviving | Stir well before serving; if the sauce has thickened too much, stir in 1 to 2 teaspoons of cold water or lemon juice to restore the desired consistency. |
| Freezing | Not recommended — the mayonnaise and dairy base will separate upon thawing, resulting in a grainy, broken sauce. |
This tartar sauce pairs beautifully with the same wines you would serve with fried fish or seafood:
- Muscadet Sèvre-et-Maine (Loire) — The classic pairing: bone-dry, mineral-driven, with a briny edge that mirrors the capers and gherkins. A perfect match.
- Albariño (Rías Baixas, Spain) — Bright, citrusy, and saline, with enough body to stand up to the creamy sauce and fried fish.
- Picpoul de Pinet (Languedoc, France) — Lean, zesty, and mouthwateringly acidic — this wine cuts through the richness of the sauce like a squeeze of lemon.
- Grüner Veltliner (Wachau, Austria) — White pepper and green apple notes complement the herbal, tangy character of the sauce.
- Sauvignon Blanc (Loire or Marlborough) — The grassy, citrusy profile provides a clean, refreshing contrast to the creamy sauce.
- For beer lovers: A crisp Czech pilsner or a Belgian witbier — both have enough acidity and carbonation to cut through the creamy richness.

Can I use Greek yogurt instead of quark or sour cream?
Yes, but the sauce will be tangier and thicker. Use full-fat Greek yogurt and consider reducing the amount by 1 tablespoon to compensate for its thicker consistency. If using low-fat or nonfat Greek yogurt, the sauce will be noticeably thinner and more acidic.
How long does homemade tartar sauce last?
Stored in an airtight container in the refrigerator, homemade tartar sauce keeps for up to 5 days. The onion and herbs will gradually lose their brightness, and the sauce may darken slightly from oxidation, but it will remain safe and flavorful. Discard if you notice any off-smells or visible mold.
Can I use dill pickles instead of gherkins?
Yes. Use 2 small dill pickle spears, finely chopped (about 40 g / ⅓ cup). Pat them dry thoroughly before adding, as dill pickles are usually wetter and more brine-packed than cornichons. The flavor will be slightly more dill-forward, which is delicious with salmon.
My sauce is too thin — what went wrong?
This is usually caused by excess moisture from wet ingredients. Make sure your onion, capers, gherkins, and parsley are all thoroughly dried before adding to the sauce. If the sauce is already made and too thin, you can try stirring in an additional tablespoon of mayonnaise to thicken it, or let it chill for 1 to 2 hours — the cold temperature will firm it up.
Can I make this sauce vegan?
Yes. Substitute the mayonnaise with vegan mayonnaise and the quark/sour cream with a thick, plain vegan yogurt (coconut or soy-based). The flavor will be slightly different but still delicious. Do not use a thin, watery vegan yogurt — it will make the sauce runny.
Should I rinse the capers?
It depends. Brine-packed capers should be drained but not rinsed — the brine adds valuable acidity and salt. Salt-packed capers should be rinsed thoroughly and soaked in cold water for 10 minutes to remove excess salt before using. Taste a caper before adding to gauge the salt level.
